  • Analysis of Ore Pass Hang-Ups in Long Vertical Ore Passes by 3-D DEM

    • Abstract: Publication year: 2020Source: International Journal of Mining Engineering and Mineral Processing , Volume 9, Number 1Akira Sato, Haowen TangLimestone is one of the most important natural resources in modern society, and it is the only mineral for which Japan has 100% self-sufficiency. In general, limestone deposits are located in mountainous areas. Thus, the bench-cut method, combined with a carry-out system using vertical ore passes, is widely used in Japan. To extract ores from mountainous areas, the ores are stored in the vertical ore passes, and then they are carried out from the bottom of the ore passes. During the storing process in the vertical ore passes, the hang-up phenomenon occurs sometimes, and several examples of hang-ups have been reported in Japan. Once it happens, it causes severe damage to the mining operations, and much effort is necessary to remove the hang-ups. To understand the mechanism of hang-up phenomena, ore flow simulations in long and vertical ore passes were carried out using the three-dimensional discrete-element method, and the influences of cross-sectional shapes, the shape of the exit at the bottom of the ore passes, and the height of the stored limestone in the ore pass were investigated. It was found that the hang-up phenomenon is strongly influenced by the cohesion and the friction coefficient. As for the size of the ore passes, a larger cross section was preferable for avoiding ore pass hang-ups. It was also found that the cross-section shape and the bottom shape of the ore pass influenced the occurrences of hang-ups, and that a square shape was preferable to avoid hang-ups. The elimination of hang-ups was also simulated. It was found that it is possible to eliminate hang-ups if a method is used to reduce the friction coefficient and cohesion. It was also found that using oscillations with higher frequency was effective.
       
  • Assessing Water Resource Issues in the US Pacific North West Region

    • Abstract: Publication year: 2019Source: International Journal of Mining Engineering and Mineral Processing , Volume 8, Number 1E. C. Merem, Y. Twumasi, J. Wesley, M. Alsarari, S. Fageir, M. Crisler, C. Romorno, D. Olagbegi, A. Hines, G. S. Ochai, E. Nwagboso, S. Leggett, D. Foster, V. Purry, J. WashingtonIn a country where ground water ranks highly as one of the nation’s most important natural resources, water stands out as a strategic item in the US West. For that, agricultural, commercial and urban communities require water for their yearly operations. Even though, groundwater serves cities and rural areas, it sustains irrigation and industries. The present levels of ground water deposit are not only at risk of over use and degradation, but in the past several years, the Western region continues to experience depletion of some of its major sources with declines occurring faster than surface water amidst grave consequences. Furthermore, in some neighboring states, water depletion has reached a critical stage with mounting threats to communities. Because over pumping of ground water sources created declines in water tables, without access to regular information on water stress and usage, managers face uphill tasks tracking the risks involved. While this issue emanates from socio-economic and physical elements including climate, the literature is sketchy on a comprehensive regional analysis. To fill that void in the literature, the paper assesses water resource issues in the US Western region using mix-scale techniques of GIS and descriptive statistics. With emphasis on the issues, water use trends, factors, impacts and efforts. While the results point to changes in water use, widespread depletion and visible impacts due to socio-economic indicators, policy and natural forces. The GIS mapping of the trends reveals the pressures to water security from various stressors (drought, depletion and the encroachment of urbanization and water intense farms) across the region. The Suggestions for mitigation ranged from the need for monitoring, sustainable use, GIS analysis, and effective policy to a regional water information system.
       
  • Economics of Exploitation Phosphate Ore Wastes

    • Abstract: Publication year: 2018Source: International Journal of Mining Engineering and Mineral Processing , Volume 7, Number 1Mohamed Abuel Kasem Mohamed, Galal Abd El Azim Ibrahim, Ahmed Mohamed Ebrahim Rizk, Mahmoud Mohamed Ahmed, Ahmed Mohamed El Nozahi, Nagui Aly Abdel-Khalek, Hasan BakheatDuring the beneficiation of phosphate ores, huge amounts of oversize phosphate ores are rejected from crushers. This reject mostly contains low P2O5 content and high gangue content. Phosphates are vital nonrenewable resources. The treatment of phosphate ore wastes of El-Nasr Mining Company, Sepaeya, Egypt aims to upgrade P2O5 percent, adds a new economic value, development of the national income, and aids to clean the mine district. The main aim of this paper is to compare different processing alternatives methods to concentrate and upgrade of phosphate ore tailings assayed 18.37% of El-Nasr Mining Company, Sepaeya, Egypt. The concentration of wastes not only add an economic value but also safe the human, animals, and plants. Two options of sizes obtained from grinding and sieving (-250 µm and -100 µm were separated to obtain the highest grade of P2O5 with the greatest recovery). The leaching process on size -100 µm raised P2O5% from 23.88% to 28.44% with mass recovery of 28.29%. The leaching process on size -250 µm raised P2O5% from 21.41% to 25.51% with mass recovery of 51.69%. For economic production, the grade of P2O5 in the host phosphate rocks should be at least 24%. In this paper, four options of different percentages of P2O5 ranged from 21.41% to 28.44% obtained from different mineral processing operations were economically compared. These options were obtained from suggested capacity of 190,000 ton/year of phosphate ore tailings assayed 18.37% of Nasr Mining Company, Sepaeya, Egypt. The net annual profit was more than 18,000,000 LE for each option. Option_2 (-250 µm resulted from grinding process) was giving the maximum profit (30,330,800 LE), the least payback period (0.16 year), and the maximum accounting rate of return (630%).
       
  • Correlations between Point Load Strength Index and Physical Properties of
           Hydrothermally Altered Rocks

    • Abstract: Publication year: 2018Source: International Journal of Mining Engineering and Mineral Processing , Volume 7, Number 1Masanori Kohno, Hiroyuki MaedaThe purpose of this study was to clarify the correlation between point load strength index and several physical properties in hydrothermally altered rocks, which are typical of the soft rocks found in northeastern Hokkaido, Japan, using axial and irregular lump point load strength test specimens. The numbers of specimens tested were 3,828 rock specimens for the point load strength test. These came primarily from the earth’s surface in ancient hydrothermal fields. The rock specimens underwent point load strength test using a laboratory testing machine with specimens in dry and saturated conditions. This study clarified the decrease in strength that can be assessed by measuring the elastic wave velocity. In addition, the results suggest that future landslide and collapse potential within a hydrothermal area can be assessed based on the hydrothermal alteration type, and point load strength index change ratio.
       
  • Modified Fatty Acids: Molecular Modeling and Docking Method for
           Optimization of Non-Sulfide Ore Flotation

    • Abstract: Publication year: 2017Source: International Journal of Mining Engineering and Mineral Processing , Volume 6, Number 1P. M. Solozhenkin, Sanda Krausz, O. I. IbragimovaFatty acids are known as oxhydryl collectors which are used in practice for non-sulfide ore flotation. However, the selectivity of these collectors is low towards to gangue minerals occurring in the ore. In the present study the introduction of substitutes into the aliphatic chain of fatty acids has been suggested as the way for improvement the selectivity of collectors. Molecular modeling of alkaline earth mineral and modified fatty acid clusters has been performed using Chem Bio 3D and ChemOffice2005 by Cambridge Soft with optimization by MM2. DTF approach has been used to determine HOMO, LUMO and SOMO energies. The occurrence of the classical transfer of charge in bidentate complex with the decrease in charge on the calcium atom of the mineral cluster has been established. The strategy of prognosis of collector activity evaluation (PCAE) has been proposed as a consistent approach to estimate the interaction between a collector and a mineral cluster as a difference of total energy and sum of cluster energy and collector energy. The approach has proved useful in identifying relevant candidates for alkaline earth mineral flotation with modified fatty acids. The strengthening effect of binary mixture of modified fatty acids on flotability of alkaline earth mineralshas been established. To optimize the flotation the combination of oleic acid(OA) and ω - ((N,N-diethyl dithiocarbamato) undecanoic acid(DEDTCUA) has been investigated with the ratio of 1:1. By using this technique the fluorite concentrate has been upgraded up to 96,3% with the recovery of 85,35%.
       
  • Assessing the Ecological Effects of Mining in West Africa: The Case of
           Nigeria

    • Abstract: Publication year: 2017Source: International Journal of Mining Engineering and Mineral Processing , Volume 6, Number 1E. C. Merem, Y. Twumasi, J. Wesley, P. Isokpehi, M. Shenge, S. Fageir, M. Crisler, C. Romorno, A. Hines, G. Hirse, S. Ochai, S. Leggett, E. NwagbosoNigeria’s abundant solid minerals constitute some of the largest known deposits in recent years under different categories. With the activities in the sector characterized by production and a growing environmental decline often overlooked. This research uses a mix scale approach of descriptive statistics and GIS methodology in analyzing the ecological impacts of mining in Nigeria. Emphases are on the issues, environmental and spatial analysis of the trends, factors associated with the issues and current efforts. The results not only reveal large deposits and changes in production, Nigeria’s mineral deposits showed continual growth much of the time despite a few declines. From a -16.98% drop in 2010-2011, aluminium deposits rose by 22.64-63.08% in 2008 to 2009 and the other years. With time, Illegal mining in Pandogari, Niger state stretched through a 17.5 km2-130 km2 radius from 1992 to 1998. By the year 2000, mining operations extended further into a vast area measuring 200 km2 and continued in 2004-2006 with more incursions onto 254-312 km2. The heavy toll of mining on the environment comes with the declines in forest land area in Bukuru, Plateau state where forest area of 420.52 km2 in 1975 fell to 399.56 km2 by 1986. The downward slide continued almost 20 years after in 2005 with only 155.63 km2 area left with green cover. The other burden of pollution risks involves the 1,000 abandoned mine ponds, alongside 1,100-4,000 tin and columbite mines left behind from the mining booms of past eras in the 1960s and spread all over Jos, Plateau. These threats are compounded further by the 400 fatalities from lead poisoning triggered by illegal quarrying in Zamfara in 2010. The GIS mapping of the trends showed clusters of areas prone to hazards and the dispersion of solid mineral potentials in the nation with the impacts linked to socio-economic elements. For mitigation, the study offered suggestions ranging from education to regular assessment of ecological liabilities and the need for policy enhancement.
       
  • Reduce the Iron Content in Egyptian Feldspar Ore of Wadi Zirib for
           Industrial Applications

    • Abstract: Publication year: 2016Source: International Journal of Mining Engineering and Mineral Processing , Volume 5, Number 2Ahmed M. M., Ibrahim G. A., Rizk A. M. E., Mahmoud N. A.The presence of coloring materials such as iron oxides in feldspar decreases its quality. To use feldspar minerals in industry, some upgrading processes should be executed to remove impurities. The most important uses of feldspar are in ceramic and glasses. The present paper aimed to reduce the iron content in Wadi Zirib feldspar ore, as well as, to obtain an optimal grade of feldspar concentrate for some industrial applications. The first processing stage was the disposal of slime’s fraction (-38 µm) which contains clay minerals. Comminution and de-sliming processes removed about 30% of iron content into -38 μm fraction. The attrition process removed only about 6% of iron content. A dosage of 97 gm/ton of Quaternary ammonium salt solution was an optimum value for mica’s minerals flotation where the percentage of Fe2O3 was about 13.65% with mass recovery of 0.44% and component recovery of 9.84%. The rejected percentage of valuable minerals into the floated mica’s minerals didn’t exceed 0.5%. A flotation test was carried out at optimum conditions for flotation of feldspar minerals. The mass recovery of feldspar concentrate was 52.11% of feed (-250+38) µm. At such optimum conditions, a suitable feldspar concentrate was obtained with 0.4% Fe2O3. The component recovery of iron content removed into feldspar tailing was about 56%. The specifications of feldspar concentrate obtained in this research fulfilled the requirements of some industries, i.e. glass, ceramic vitreous tiles, and semi vitreous tiles. The final results revealed that the total disposal percent of iron content was about 75% of that present into the feed head sample.
       
  • Design an Appropriate Mining Method for Extraction of Ore between 330ml
           and 400ml at Baluba East Upper T-Block

    • Abstract: Publication year: 2016Source: International Journal of Mining Engineering and Mineral Processing , Volume 5, Number 1Njamba Mike Njamba, Victor MutamboBaluba mine was commissioned in 1973 and since then over 55 million tonnes of ore has been mined leaving out only 8.4 million tonnes reserves at very low block grade and structurally thin and difficult to mine. The area referred to as Baluba east has the ore body lying below 330 ml and 400 ml. The ore-body has thickness ranging from 6 to 10.5 m with a dip of 21 degrees and erratic grade. Attempt to mine the area in question has not been so successful as the reserves become thinner and also occur in poor ground conditions area. Therefore, this study was undertaken in order to select an appropriate mining method for extraction of the ore between the above mention levels within T- Block from SS 37 to SS 40. The study involved three phases: Analysis of actual geotechnical information at the mine; selection of the mining method using the University of British Columbia method (UBC) and the UNZA Mining method Selection tool. The best Mining method (Single level caving) was then subjected to cost analysis to establish its viability. The total cost calculated for the project was $ 2,990,869.92 and the expected revenue is $ 4,782,590.77 giving a payback period for the investment of approximately 6 months.
       
  • Comparative Analysis of Rock Mass Rating Prediction Using Different
           Inductive Modeling Techniques

    • Abstract: Publication year: 2016Source: International Journal of Mining Engineering and Mineral Processing , Volume 5, Number 1Sajjad Hussain, Noor Mohammad, Mujahid Khan, Zahid Ur Rehman, Mohammad TahirThe rock mass rating (RMR) classification system is the integral part in the engineering design and accomplishment of underground structures especially tunnels and caverns within the rock mass. Therefore, it is very necessary to evaluate/predict the quality of rock mass and in turn the RMR value with more precision. This paper presents the estimation of RMR value using three different techniques including conventional method, Multiple Linear Regression (MLR) and Artificial Neural Networks (ANN) using the real time geological and technical data obtained along the tunnel axis at Golen Gol Hydropower Project Chitral, Pakistan. The RMR values were estimated using ANN-based and MLR models, the results were compared and analyzed. On the basis of comparison, it was observed that ANN-based models results in more realistic values of average RMR than other models for all three bore holes. In comparison with ANN-based models, the MLR model overestimates the RMR value which is not appropriate according to stability point of view. The improved RMR value predicted using ANN-based models can be used for the recommendation of the reliable support system for tunnel.
       
  • Experimental and Analytical Studies to Achieve an Optimised Cemented
           Backfill Mix to be Used in a Cut-Fill Mining Method

    • Abstract: Publication year: 2016Source: International Journal of Mining Engineering and Mineral Processing , Volume 5, Number 1Kambiz Tahzibi, Mehdi Nasiri, Bijan Mashoof, Shokrollah LotfiThe use of backfill in underground mines is increasing due to the need to achieve maximum ore recovery and to maintain the stability of underground excavations. The mechanical response of the backfill in narrow openings is significantly influenced by its interaction with the surrounding rock mass. This paper discusses the compressive strength required for cemented backfill used in mine backfilling and the method which is to be applied in VENARCH Manganese Mine in Iran. The minimum required compressive strength of the backfill is determined by the analyses results and the loader weight operating in the mine. The magnitude and distribution of the major principal stress contours demonstrate that the required uniaxial or unconfined compressive strength (UCS) of the backfill materials would need to be at least 1MPa. Cognisance of this requirement, together with the laboratory test results, demonstrates the need for a cemented backfill mix. Moreover, the mixture should have an appropriate level of rheological properties and sufficient compressive strength to meet the anticipated static and dynamic loads, while minimising the overall execution cost. This paper deals with the design of a Low Cement Content High Workability Concrete (denoted as LCHWC) mix, which is aimed at meeting the requirements.
