There is no method for separating gold from silver, or other precious metals, when smelting. The ore containing the metal when melted will form an amalgam – an alloy of gold and silver, or whatever precious metals are in your concentrates. Let the refinery separate precious metals – it9s really the easiest and cheapest in the long run.

The gold ore crushing process often uses jaw crusher for coarse crushing, standard cone crusher for medium crushing, and short head cone crusher and roll crusher for fine crushing. Most medium and small gold processing plants use two-stage closed-circuit crushing, and large-scale processing plants use three-stage closed-circuit crushing process.

Pyrite Processing Plant. Ore information: The mineral ores contain 35.68% sulfur, 29.24% iron, and 3.65g/t gold, with a high extraction value. According to phase analysis, the gold in the ore mainly exists as gold sulfide, gold oxide, and gold silicate. We must destroy the pyrite crystal structure in the sample to fully expose the gold mineral before we can recover the gold.
