      Abstract: The Bonsa river is an important tributary of the Ankobra river in the Western Region of Ghana. The catchment of the Bonsa river has been undergoing rapid land cover changes due to human activities such as farming, illegal mining, population growth, among others which are likely to promote soil erosion and sediment yield in the river basin. To estimate the amount of soil eroded over a period and subsequent sediment yielded along the Bonsa river basin, the Revised Universal Soil Loss Equation (RUSLE) was integrated with Geographic Information System (GIS) to model the spatial distribution patterns in soil erosion and sediment yield within the catchment. Data used included annual rainfall records, soil map, Digital Elevation Model (DEM) and land-use map of the study area. Parameters of the model were determined and converted into raster layers using the raster calculator tool in ArcMap to produce a soil erosion map. The concept of Sediment Delivery Ratio (SDR) was applied to determine the annual sediment yield by combining a raster SDR layer with soil erosion map. The predicted soil loss and sediment yield values were found to be low. This may be due to high soil protective cover provided by vegetation as well as low topographic relief in the river basin. Though, the elements and processes responsible for soil erosion and sediment yield prevailing in the basin was found to be low, adverse situations could be developed with time if the prevailing conditions are not checked, as soil erosion is a natural gradual slow process. The gains made could be sustained by putting measures in place to control human activities, particularly, illegal mining (galamsey) in the basin, indiscriminate cutting down of trees and farmining activities along the Bansa river basin. This study will support monitoring, planning of water resources and help to improve sustainable water quality.

      Abstract: Cement bound concrete materials and complementary fittings are requisite ingredients for all civil engineering works. In all these, Portland cement, a basic binding ingredient for the concrete work is the dominant binder. In Ghana, there are various brands of cement on the market. Five major brand products currently in circulation include the Ghana Cement (GHACEM), Western DIAMOND Cement (DIAMOND), CIMAF Cement, DANGOTE Cement and SUPACEM Cement. Increased infrastructural development has placed high demand on cement consumption. Consequently, new products keep emerging in the market. Indeed, a standard measure to provide product marking and evaluations of conformity to standard Class thresholds are required for the desired specification, properties and the performance quality of the cement products. This research therefore sets to ascertain the strength quality of the five cement brands on the Ghanaian market by checking their conformity to C-30 and C-40 standard compressive tests, using their 32.5-R and 42.5-R flagship brands. To achieve this, concrete cubes were moulded with fixed mix ratio of 1:1⅟2:3 and 1:1:2 for C-30 and C-40 respectively. To achieve the desired strength conformity, the slump as well as the coarse and fine aggregate constituents were standardised. The results indicated that the cement brands despite parading same strength thresholds in the market, do not exhibit same strength build-up. There are significant variations in growth of compressive strength over time. It was observed also that conformance threshold within 28 days was not attained for a number of the brands. Indeed, not until 56 days or more some of the brands could not achieve their desired compressive strength thresholds.

      Abstract: The objective of this research is to establish the importance of Sample Repeatability Index (SRI) as a measure to ensure error minimisation in exploration drilling protocols, during sample preparation of the prospect areas. Almost all the stages entailed in the exploration stages involve sampling. Samples collected and prepared within the field are well checked for a good Quality Assurance and Quality Control (QA/QC) methods. However, samples sent out for testing in the laboratory outside the field are not under the control of the exploration team, hence a measure must be taken to assess the efficiency of the laboratory and accuracy of the laboratory results. Sample Repeatability Index is one of the tools that can be used to ensure the degree of confidence in the laboratory results. To achieve this, QA/QC procedures were employed to monitor precision, accuracy and potential sample contamination in order to ensure confidence in the sampling system. A total of twelve thousand and eighty-one samples taken from eight different deposits, considered within a 4-year period were used in this study. Field duplicate pairs were used to check sample repeatability, Relative Difference and Half Absolute Relative Difference (HARD) plot were used to calculate Sample Repeatability Indexes for the deposits. Results of the study showed that Sample Repeatability Index for all the deposits with exception of deposit 2 fell below the Customer Specification Threshold (CST). Deposit 2 produced somewhat better of 77% at 20% precision as compared to the other deposits. Deposit 3 recorded poorly of 60% at 20% precision. It is advisable to have sampling protocol designed to suit different geological domain on each individual deposit.

      Abstract: On average, small-scale miners can recover gold ranging from 20% to 70% of the total available gold by the conventional gravity separation methods only. As a result of this, tailings materials from Artisanal Small-Scale Gold Mining (ASGM) operations contain a significant amount of gold, and characterisation of these materials would inform metallurgical decisions concerning reprocessing of the tailings from ASGM. In this study, size-by-size analysis, gold grade, gold deportment, and cyanidation studies were carried out on ASGM tailings samples collected from five different locations (Asankragua, Bogoso, Prestea, Wassa-Akropong, and Tarkwa) in the Western Region of Ghana. Head grades of tailings samples from Asankragua, Bogoso, Prestea, Wassa-Akropong, and Tarkwa were 1.84 g/t, 4.12 g/t, 0.45g /t, 0.17 g/t, and 5.97 g/t, respectively. The 80% (P80) of the tailings materials passed through 1.797, 0.578, 1.636, 3.210, 0.380 mm screen sizes for samples from Asankragua, Wassa-Akropong, Tarkwa, Prestea and Bogoso, respectively, with an average of 1.52 mm. Also, the gold deportment analysis revealed that the highest metal distribution of 42.03% in -106 µm size fraction for samples from Bogoso, followed by 31.0% for Wassa-Akropong, 29.7% for Tarkwa, 27.0% for Prestea, and 22.0% for Asankragua. It was shown after cyanidation test works that the highest gold recovery was 81.5%, 72.3%, 75.3%, 65.6%, and 38.5% for samples from Wassa-Akropong, Asankragwa, Prestea, Tarkwa, and Bogoso, respectively. Cyanidation can thus be employed to get higher gold recovery in ASGM.

      Abstract: To present information such as causes of accidents and their consequences on the Ghanaian mining industry in the safety literature, classification schemes for incident analysis within the safety literature were studied. Human Factor Analysis and Classification Scheme (HFACS) emerged suitable for incident analysis. Base on its suitability for incident analysis within the Ghanaian Mining Industry (GMI), a derivative of the HFACS, namely HFACS-GMI, was proposed. This research seeks to study the usefulness and the applicability of the HFACS-GMI. Collectively, 56 incident investigation reports were obtained from an open cast gold mine in Ghana and analysed using the HFACS-GMI. Two cases, an equipment damage incident and an injury incident, were used to demonstrate the coding processing in identifying the causal factors. The analysis shows that most mishaps are associated with adverse workplace/operator conditions (151 references), with the physical environment (72.2%) being cited as the major causal code under the tier. Management decision showed a major contribution (74.1%) to mishap under the causal codes. Most cases were attributed to mistake error (57.4%) followed by the contravention (51.1%) of set rules and procedures with the operator's act tiers. Inadequate work standards (27.8%) and failure to ensure competency (24.1%) under the operational process and leadership flaw causal codes, respectively, were identified as the most cited nanocode. Management decision is critical in a mishap and should be given much attention in developing accident prevention strategies. The study has demonstrated that HFACS-GMI is very useful and applicable for incident analysis within the mining industry and is recommended to study causal factors across the mines.

  • Assessing the Toxicity of Colocassia Esculenta (Cocoyam Plant) Grown on
           Mercury Contaminated Soil

      Abstract: The unsafe disposal of heavy metals is a serious environmental problem all over the world as it has devastating effects on plant biodiversity as well as animal and human health. Contamination can be caused by effluents from industries and exposure of rocks containing metalloid or heavy metals such as arsenic (As), lead (Pb), and mercury (Hg). Several techniques have been used to clean up soil and water bodies contaminated with these heavy metals or metalloid. Phytoremediation is one of the emerging methods which has proven to be ecofriendly and efficient. Plants such as Colocasia esculenta have been reported to be a hyperaccumulator. However, there are concerns regarding the excessive metal uptake by the plant when grown on mercury-contaminated sites, since high Hg levels can cause toxicity in human beings. This study was thus carried out to ascertain the toxicity of C. esculenta plants cultivated in 10 ppm Hg-induced soil sample for four weeks. The concentration of mercury in soil, water and cocoyam samples decreased after 28 days of planting. Accumulation of Hg in plant tissues was measured, and Translocation Factor (TF) was calculated. TF was in the order of Root-Stem (0.60) > Root-Leaves (0.56) > Soil-Root (0.23).  The results indicated that Cocoyam plants have an excellent ability to remove Hg from contaminated soils and further accumulate it in their tissues. With the threshold level of Hg at 0.0016 mg/kg body weight (FAO/WHO), the results obtained suggest that cocoyam plants grown in such contaminated areas may pose health threats to humans.

      Abstract: Most toxic Heavy Metals (HM) persist in oil-based mud and ecosystem for many decades after the application of mud for drilling oil and gas wells. This study assessed the attenuation of such heavy metals from waste oil-based mud using activated carbon produced locally. The oil-based mud analysed presented variable levels of Iron (Fe), Copper (Cu), Nickel (Ni), Potassium (K), Arsenic (As), Chromium (Cr), Manganese (Mn) and Zinc (Zn). Adsorption is a highly effective means of separation to remove a wide range of pollutants in waste streams. Coconut shell activated carbon (CS-AC) was locally produced to remove heavy metals from the waste oil-based mud to encourage value addition to waste. The adsorption data was fitted to Langmuir and Freundlich isotherm model using linear regression analysis. The data was more fitted to the Langmuir isotherm as indicated by the high goodness of fit values (R2). To reduce the heavy metal concentrations below threshold levels optimum CS-AC dosage required for Fe, Cu, Ni, K, As, Cr, Mn and Zn is 5 g/l of CS-AC for a contact time of 30 minutes. The characterization of the produced carbons shows good results comparable to other commercial activated carbons. CS-AC is a viable and economical product for the removal of toxic heavy metals from waste oil-based mud before disposal.
