The new process also can be used to extract gold from consumer electronic waste. Current methods for gold recovery involve the use of highly poisonous cyanides, often leading to contamination of the environment. Nearly all gold-mining companies use this toxic gold leaching process to sequester the precious metal.
Kelly added: "Using our technology, we currently estimate average value for typical fly ash at around $200-$250 per tonne. "Even at observed average concentrations of 7.5ppm of gold in fly ash, a 50% recovery would increase this value to $350-$400 per tonne, while recovery would increase this to around $500-550 per tonne."

Activated carbons are used to recover gold from cyanide solutions, which are percolated through gold-containing ores, aka 'pay dirt'. Three main technologies exist for recovering gold from cyanide leachate solution: – Carbon-in-Pulp (CIP) – Carbon-in-Leach (CIL), includes 'Heap Leach' – Carbon-in-Column (CIC)
The proposed technology allows to decrease preg-robbing activities of concentrates treated by subsequent cyanidation. Total gold recovery by the proposed technology from the ore with a head grade of 0.8 g/t was 83.9 per cent. The gold loading onto the activated carbon from CIL process was 6.500 g/t.

One process for gold recovery is known as cyanide leaching. We use a cyanide solution to dissolve the gold out from the gold mine, collect the solution, and then use a reducing agent to reduce the gold out and retrieve it. Cyanide leaching produces almost 80% of the gold in the world. But cyanide is very toxic, so it is very hazardous to the ...

fine gold. This fine gold may be recovered by amalgamation which involves the dissolution of gold or silver in mercury. The resulting alloy, amalgam, is relatively soft and will adhere readily to other pieces of amalgam or to mercury.5 Historically, amalgamation was widely used in the United States for recovery of gold and silver from their ores.
