The processing of gold scrap varies not only with the gold content but also with the amenability of the gold in the scrap to extraction Thus the bulk of the gold may be recovered by leaching techniques using cyanidation or aqueous chlorination and the residue may then beMore Details
Amalgamation is accomplished by passing a slurry of ore over copper plates coated with mercury by mixing a slurry of ore and mercury in a cylindrical or conical vessel called an amalgam barrel or by grinding the ore in a ball rod or pebble mill to free the gold from the mineral matrix and then adding mercury to the mill and continuing grinding until the gold has dissolved in the mercuryMore Details
