The process for separating gold from ore usually involves crushing the ore and then treating it with a cyanide solution. this bonds itself to the gold and drains it from the rock. but the waste, called tailings, is left behind after the gold is extracted.See Details
The boddington copper gold ore is of similar rock competency to that selected for this study and thus provides a good contrast between comminution processes designed to liberate minerals for flotation, in which the whole ore is ground to fine size, and the comminution process with the staged rejection of silicates.See Details
The processing of gold ores has traditionally made use of conventional crushing and grinding circuits. in each case where gold is formed either as coarse native particles or in coarse grained sulphides, it is recovered by gravimetry concentration in the in the comminution circuit in addition to recovery of finer values by leaching.See Details
For starters, you need around 12 tons of ore to produce a single ounce of platinum. turning this ore into platinum is a complex process that involves: crushing the ore into small particles. mixing the crushed ore with water and other chemical reagents. blowing air into the mixture to force platinum particles to the top of this chemical soup.See Details
From ore to dor . more gold is recovered by cyanidation than by any other process. in cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. when gold dissolution is complete, the goldbearing solution is separated from the solids. with ores of higher gold content (greater than 20 grams of gold per tonne of ore.See Details
