Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from lowgrade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the goldcontaining solution is leached. Then used the method of carbon adsorption, zinc powder displacement device and so on to separate gold from the liquid ...

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), cyanidation is accomplished by vat ...

· Gold mixes with different minerals, which will affect the look of the ore. If you are looking for larger chunks of gold, stick to lode deposits, where plate tectonic activity has brought gold to the surface. Lode deposits usually form gold in larger veins, so it should be easier to see. Smaller flecks of gold are more common in placer deposit gold ore, which tends to look like that area''s ...

Only a few minerals are important as gold carriers. Native gold is by far the most important, followed by gold tellurides. Other gold compounds are economically irrelevant. There is a series of minerals that can carry gold as a physical constituent such as pyrite and arsenopyrite. The mineralogy determines the recovery process of gold. Two types of gold ores can be distinguished: Non ...

A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pretreatment in order for cyanidation to be effective in recovery of the gold.

The principal gold minerals that affect the processing of gold ores are native gold, electrum, AuAg tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the AuAg tellurides, and very finegrained gold (<10 µm) locked ...
