4 Extraction Processes for Gold-Pyrite Ore

2020-10-21  The Extraction Processes of Gold-Pyrite Ore The treatment principle of gold-pyrite ore is to separate the sulfide from the gangue and dissolve the gold in the cyanide solution. In order to remove antimony, arsenic, carbon and other substances that absorb fluoride, roasting treatment is required before cyanidation. There're 4 extraction processes.

Ask The Experts How do I recover gold in pyrite?

Miners who process gold ores will get free gold particles that can be melted into bars, but they also recover pyrite that has small amounts of gold within it. Often the majority of the gold is in the free particles, but sometimes the pyrite can also contain important amounts of gold.

The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag 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 Au-Ag tellurides, and very fine-grained gold (<10 µm) locked
