A comprehensive investigation of Au leaching from gold ores with a solution containing thiourea and ammonium thiocyanate was performed. A gold ore A with 18 g/t of Au and 1.15 wt.% of sulfur and another gold ore B with 55.7 g/t of Au and 11.67 wt.% of sulfur were used. The percentages of extracted Au were 57%, 66% and 95% for the …

The treated ore is then cyanided in the usual way and the gold recovered by electrolytic precipitation. Whether or not any precious metal was dissolved in the preliminary cyanide treatment was not stated. In another elimination method the copper mineral is dissolved out by means of ammonia after which the ore is cyanided as usual.

Removing the gold-bearing 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.
