The environmental impact of gold production

processing. As non-refractory ores become depleted, the ability to recover gold from refractory ores has become more important. For an ore grade (i.e. metal content) of 3.5 gram per tonne of ore, the study estimated that production of each tonne of gold from non-refractory ore used approximately 200,000 gigajoules (GJ) of energy and 260,000 tonnes of water. It produced 18,000 tonnes of GHGs ...

How Is Gold Extracted From Gold Ore? | Sciencing

Another process involves ground ore being passed over plates which are coated with mercury. The gold and the mercury form an amalgam, leading to the name of the process, amalgamation. Once the amalgam has formed, it is heated until the mercury gas is boiled off, leaving the gold. The mercury gas is highly toxic and must be handled carefully.
