MINING & CYANIDE - Environmental Impacts

Mining and Cyanide

The management and treatment of cyanide-containing wastes and wastewaters from gold mining operations continues to be closely scrutinised by regulatory authorities. There have been examples of excursions of wastewaters containing cyanides due to spills and leaks from mills, ponds, leach pads, tailing dams, etc.

Clearly, cyanide containing effluents must be treated prior to disposal to receiving water environments. This also applies to cyanide-containing wastes such as spent heap leach agglomerates.

Troubleshooting

EnviroGulf Consulting can undertake trouble-shooting assignments and field investigations of mining operations having environmental cyanide problems and liaise with government regulatory authorities on behalf of clients. Often there is much debate on the correctness of cyanide analytical methods and the application of water quality criteria for cyanides, especially where ambient standards are applied at the boundary of mixing zones in receiving waters. The Principal of EnviroGulf Consulting has solid experience in this area and has successfully negotiated with regulatory authorities on behalf of clients.

Discussions with mining and process engineers will serve to identify and characterise existing operations, particularly with regard to ore types and blends which may give rise to cyanide problems through excess cyanide demands with resulting spikes of cyanide in process circuits and discharges.

Relevant Experience
