Home Effluent Limitation Guidelines For Copper Mines And Mills
The physical and chemical qualities of the process effluent and the tailings dam wastewater of AngloGold-Ashanti Limited, a gold mining company in Ghana, were studied from June to September, 2010. The process effluent from the gold extraction plant contains high amounts of suspended solids and is therefore highly turbid. Arsenic, copper and cyanide were …
Effluent guidelines are national standards for wastewater discharges to surface waters and municipal sewage treatment plants. We issue the regulations for industrial categories based on the performance of treatment and control technologies.
Chapter 6 Water Quality-Based Effluent Limits 6.1 Overview of Water Quality Standards WQBELs involve a site-specific evaluation of the discharge and its effect on the receiving water.
