Holes are drilled into the rock face at the end of a tunnel and explosives are placed into the holes. The explosions blast the rock into pieces. The broken rock is taken out of the mine to a mill where it is crushed and the gold collected. Tunnels are dug deep underground to
By 2000 bc the process of purifying goldsilver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower. By ad 100, up to 40,000 slaves were employed in gold mining in Spain. The advent of Christianity somewhat tempered the demand for gold until about the

A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation, and the separating of silver and gold by leaching with nitric acid is referred to as parting.

Extraction of gold and silver involves leaching with CN ion. Silver is later recovered by : Option 1) liquation Option 2) distillation Option 3) zone refining Option 4) displacement with Zn
Parting of Gold from Silver The parting of gold from silver is effected by melting the raw product with sufficient silver to make the ratio of the gold to silver 1:3, or quot; quartering,quot; the alloy being then treated with concentrated sulphuric acid or nitric acid.
Removing the goldbearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
