Zimbabwe has a substantial number of mines and 67 minerals have been mined in the country since 1900 but at present only 30 different minerals are being mined. Exploitation of a variety of ores, in rocks of diverse composition, provides the potential for a range of pollution problems. ... gold-mine dumps, base-metal mine dumps (dumps associated ...
It is therefore an established fact that mine dumps generate severe acidic and chemically noxious environments that effect the health of people living close to mine dumps. With time, wastes from mine dumps find their way in water bodies and they have great impact on agricultural land, they contaminate groundwater and surface water; and …

Abstract The effect of seepage from a gold mine slime dam on the levels of trace heavy metals in a nearby receiving stream and dam were studied between 1993 and 1995. The heavy metals studied include Cd, Mn, Fe, Co, Ni, Pb, Ag, Cu, Zn and Cr. The major cations Na+, K+, Ca2+, Mg2+, the SO4 2‐ anion, pH, alkalinity, and hardness …

Mercury exposure can be deadly. So why are gold miners in Zimbabwe using the dangerous chemical — and risking their lives and the health of their communities in the process?
His main research has been on groundwater and groundwater pollution cases near mine dumps and operating mines for the 12 years. He worked on the effect of cyanide in gold mine dumps in Zimbabwe, then proceeded to work on the Berg Aukas mine dumps and slags in Namibia, which led to the re-location of the Youth service camp to a different …
From the study it emerged that the minor metals dumps show the worst pollution risk, followed by base metal dumps, gold-mine dumps, platinum group metals mine dumps, chromite asbestos mine dumps and sulphur mine dumps.
A combination of factors are considered important in causing the failure and subsequent development of a flowslide of a gold mine waste dump (or tailings dam) at Arcturus, …
Dr Steve Chingwaru, a 26-year-old geometallurgist, has made a discovery that could revolutionise South Africa's gold mining industry and inject billions into its economy. His groundbreaking PhD ...
A combination of factors are considered important in causing the failure and subsequent development of a flowslide of a gold mine waste dump (or tailings dam) at Arcturus, near Harare, Zimbabwe. These factors comprise poor basal drainage, steep perimeter walls, saturation of the walls and basal sediments through continued spigoting of slurry during …
We discovered that mining caused extensive environmental destruction, creating artificial hills and open pits as well as promoting massive soil erosion, …
The objectives of this study were to: (i) assess the environmental impacts of illegal artisanal gold mining in Chewore Safari Area (CSA) and (ii) assess trends in …
