Treatment of small scale gold mining wastewater using pilot-scale sedimentation and Cocopeat filter bed system

The use of amalgamation process to recover gold from mined ores by the small-scale gold miners in the Philippines and other developing countries produces and dispose of untreated wastewater to the receiving water bodies. In this study, a field-scale filter bed system was constructed to treat heavy metal metal-laden wastewater collected from small-scale gold mining site in Paracale, Camarines No...

Management challenges on small-scale gold mining activities in Brazil.

This article presents a focused study of environmental management in small-scale gold mining, called garimpo, at the Tapajós River in the Amazon basin (Brazil). Environmental management is necessary in this very important area not only for Brazil but for the general world welfare. The fact that this is a very dispersed area, with a very low economic and education level, complicates the issues. ...
