Gold extraction refers to the processes required to extract gold from its ores This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

Gold is mined in Australia using various methods, including an underground method According to mining company Citigold, this process involves accessing the gold using two downward angled tunnels or declines five meters long and five meters high, allowing for the mining equipment to fit through it

2000 A The amount of gold you will get from 4 tons of circuit boards may not be worth the effort and cost There are at least two ways to get the gold: 1 cut off the tabs and strip them in cyanide 2 burn the entire collection, smelt the copper and gold out of the ash, then extract the gold from the copper

The dissolved gold in solution is adsorbed onto activated carbon When the carbon is loaded with enough gold it is removed from the circuit and sent to elution where the adsorption process is reversed and the gold is stripped off the carbon back into solution, electrowon and smelted into bars

Gold cyanidation also known as the cyanide process or the MacArthur-Forrest process is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex It is the most commonly used leaching process for gold extraction Production of reagents for mineral processing to recover gold, copper, zinc and silver represents
