US Environment Protection Agency USEPA regulations require mining operations to remediate their waste streams prior to environmental discharge. Wastewater streams from gold mine operations can be particularly toxic due to the potential for cyanide contamination and the concentration of metals contained in the wastewater effluent.
Oct 07, 2020 Connecting a remote mine to a central treatment plant via pipeline is expensive, time-consuming, and requires negotiation of complex right-of-way issues, so mining operations typically require decentralized treatment of water and wastewater. Decentralization, in a nutshell, means siting treatment near the water source, demand, or ideally both.
