Eco-friendly gold leaching | Eco-Goldex Reagent

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

Seismic analysis and design of cyanide leach tank foundations

The agitation leaching method is to concentrate the slurry, obtained after grinding and classifying of the gold-containing ore, to a suitable concentration, place it in a leaching tank, add a cyanide solution, and aerate to carry out leaching. The main equipment used in the agitation leaching process is a cyanide leaching tank.

Improving the process performance of gold cyanide leaching ...

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.
