What Is the Process of Refining Silver? Silver is found embedded in several different minerals, namely copper, zinc and lead, and the refining process varies depending on the source. Silver derived from copper and its derivatives, including copper sulfide, requires different handling and refining techniques than silver minerals taken from zinc ...

Heating ores to elevated temperatures is called roasting, and it causes the oxygen in the air to convert the sulfur in the ore to sulfur dioxide, which is a gas and is emitted to the air. The process works best when the ore is crushed to small pieces before roasting.

> At the Kurara gold project the ore was so viscous it would not flow out of the mill even with lower densities. > Also cyclone efficiency is negatively affected resulting in a less sharp separation. Clays affect the grinding efficiency necessitating operating the mill with a lower density to flush the clay out of the mill

Ore processing consists of the following stages: crushing and grinding of the ore. addition of process water (generally decanted from the tailings pond) to form a slurry. addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into solution.

Plant surveys demonstrated that the gold was liberated in the primary grinding circuit and concentrated in the primary cyclone underflow streams .From this point on. the capacity to recover this gold is hindered by overgrinding, flattening, and tarnishing of the surfaces of liberated gold particles.

The entire furnace charge is then poured into moulds, resulting in bars of gold bullion ready for shipment. Gold is recovered from pregnant (gold bearing) solution by the process of electrowinning. An electric current is passed through the solution causing solid gold to plate out on steel wool cathodes.

Agglomeration Drums for Processing Gold Ore
