2015-9-17 Bibiani like any other surface gold mining can be a major source of pollution to the surrounding water bodies. The major chemical used in extracting gold in CAG is mainly sodium cyanide solution in the Cyanide Inland Leach (CIL) plants. This chemical used in the gold extraction and the leachate from the waste and / or ore dumps turns to affect the

2020-11-2 Cyanide is often spilled into waterways during gold mining, and when ponds filled with mine wastes burst and spill. Mining companies say that cyanide in water quickly becomes harmless. But this is true only when there is lots of sunlight and oxygen. Even then it leaves behind other harmful chemicals.

2015-1-4 The gold is then purified. Mining companies state that under sunlight cyanide in water rapidly breaks down into largely harmless substances such as carbon dioxide and nitrate. It also tends to react readily with many other chemical elements, however, and is known to form hundreds of different compounds. While generally less toxic than the ...
