Cyanide Use in Gold Mining Earthworks

Vat (or tank) leaching: The ore is mixed with cyanide solution in large tanks. Although the chances of spills are lower because the leaching process is more controlled, the resulting waste, known as tailings, is stored behind large dams (tailings impoundments) which can and do fail catastrophically. Cyanide's efficiency makes mining more wasteful

Improving the process performance of gold cyanide leaching

dissolve, gold cyanide leaching reactors are usually very large, with a size of up to 5000 m3. For the same reasons, the solids content in tank leaching is kept at a high level, around 40 wt.%. Currently, a typical agitator configuration in a cyanide leaching reactor is two downward-pumping hydrofoil impellers, as illustrated in Figure 1.

Application Note Cyanide Leach Process pH

Cyanide Leach Process pH Mining: Gold Processing While there are many different processes to remove gold from its encapsulating ore, cyanide leaching (cyanidation) is perhaps the most common and well known. A cyanide solution (NaCN or KCN) is elevated to a high pH level (>10.5pH) so that free cyanide (CN-) will dissolve the gold in the ore.

How to Fix Agitator Mixer Problems in a Gold Leach Circuit

A cyanide leaching circuit usually consists of large agitated tanks for mixing mineral slurry with cyanide in order to extract gold. Typically, the slurry consists of 30-40% solids by weight with the solid particles being less than 100 microns (0.1mm) in size. Air or oxygen is often bubbled through the slurry to improve the leaching reaction
