DIAMOND MINING AND THE ENVIRONMENT FACT SHEET

Diamond mining uses water, rather than chemicals, for extraction, but of course, water is scarce in many parts of Africa, where diamond mining companies often operate. This makes it even more important that the diamond mining process does not pollute natural water sources and that it uses as little as possible. Taking action

The Mining Process – Waihi Gold

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.
