Abstract This study assesses the contribution of small scale mining towards environmental degradation. Field observation, insitu measurements and laboratory analysis were conducted to determine environmental consequences caused by poor adherence to standard mining practices by artisanal and small scale miners in Ashiraq Mines in Tanzania. Field observation revealed significant land and soil disturbance in the study area such as the existence of abandoned old workings. Direct measurements of p...
Box 35176, Dar es Salaam, Tanzania Abstract Soil stabilization by addition of industrial solid wastes in order to increase trace metals retention and (a minor secondary effect) to dilute their concentrations is an environmentally friendly and attractive soil remediation process that attenuates trace metals impact. In this study, non-hazardous industrial by-products (sugar foam, gypsum, zeolitic materials and fly ashes) were tested using laboratory scale STECH,4(2), S/NO 10, MAY, 2015 87 Copyr...
Abstract The objective of this experimental study was to determine the kinetics and equilibrium sorption of Cr(VI) in soils collected from Hengshui City of Hebei Province, China, based on batch experiments. The main concentration for this paper is on the effect of soil pH, solute concentration and ionic strength as the variable factors in the sorption of Cr(VI) in soils and the assessment of their implications to the environment. Atomic Absorption Spectrophotometer (AAS) was used for Cr(III) ...
ABSTRACT The Paboase deposit located in the Chirano gold district is hosted in Paleoproterozoic rocks within the Sefwi-Bibiani volcanic belt of the Birimian, which has been regionally metamorphosed to greenschist facies. Gold mineralization at Paboase is largely hosted by albite-pyrite-carbonate altered mafic and porphyry intrusive rocks rather than Birimian sedimentary rocks and graphitic shear zones which are well known style of mineralization in southwest Ghana. Multi-element geochemistry ...
ABSTARCT A seismological and geological investigation for earthquake hazard in the Greater Accra Metropolitan Area was undertaken. The research was aimed at employing a mathematical model to estimate the seismic stress for the study area by generating a complete, unified and harmonized earthquake catalogue spanning 1615 to 2012. Seismic events were sourced from Leydecker, G. and P. Amponsah, (1986), Ambraseys and Adams, (1986), Amponsah (2008), Geological Survey Department, Accra, Ghana, Ampo...
ABSTRACT Assessment of viability of an ore deposit depends on the accurate estimation of the quantity and quality of the commodity, which is a function of the sample data quality. SAMEVA Limited, a fully owned Ghanaian company, wants to acquire Kojina Gold deposit as an investment opportunity in the gold industry of Ghana. The decision to invest in the mining industry comes with huge capital requirement and the associated risks are very high. The major objectives with regards to evaluating th...
