2022-11-2 In the future, gold and copper extraction from the earth could be undertaken with plants this technique is called “phytomining”. In the last step of gold processing, refineries analyse the gold obtained and separate it from other minerals and elements. The result is fine gold with up to 99.99 % gold content the outcome of gold production.

2017-9-7 At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost

2016-4-6 By mixing mercury with crushed ore, even the finest particles of gold could be collected. After heat-treating the resulting slurry, miners could separate the mercury and gold for processing. Gold cyanidation dates back to 1783 when Carl Wilhelm Scheele discovered that gold could be dissolved in an aqueous cyanide solution.
