Potential heavy metal pollution of soil and water

2019-4-1  Globally, small-scale mining is noted to be a major contributor to the pollution of water resources because it makes use of huge volumes of water thereby polluting the water resources (Cunningham et al., 2005; Owens et al., 2005). Most artisanal mining operators have no concession of their own and, thus, operates illegally.

Assessment of Soil Pollution (Heavy Metal) from Small

Small scale gold mining activities can cause negative impacts on both society and the environment [1], [3], [8-9]. The nature and type of the impacts depend on the type of the mineral being mined, the mining and mineral processing methods in use and the mining phase [3]. Uncontrolled mining operations can be a source of heavy metal pollution to

Heavy Metal Pollution in Soil and Water in Some

Illegal small scale gold mining popularly called “Galamsey” in our local communities is on the increase. This has led to concerns about the level of environmental pollution resulting from these mining activities. This work was conducted to determine the level of heavy metal contamination in the environment due to the activities of the small scale miners.

This work examined heavy metal pollution from a large-scale cyanidation gold mining operation, which is distinguished from artisanal and small-scale amalgamation gold mining, in Jilin Province, China. A total of 20 samples including one background sample were collected from the surface of the mining area and the tailings pond in June 2013.
