4 Extraction Processes for Gold-Pyrite Ore - Mining

2. 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.

Beneficiation of pyrite from coal mining - ScienceDirect

2016-12-15  An abundant mineral in nature and despite its potential as raw material for different segments of industry, when it comes from coal mining, pyrite (FeS 2) is treated as waste, and its disposal culminates in environmental problems for the coalfields. Increasing the purity of pyritic tailings, increasing its iron disulfide content, strengthen the possibility of turning it into a value-added by-product.

Massive Sulfide Ores in the Iberian Pyrite Belt ...

The Iberian Pyrite Belt (IPB) is recognized as having one of the major concentrations of volcanogenic massive sulfide (VMS) deposits on Earth. Original resources of about 2000 Mt of massive sulfides have been reported in the province. Recent classifications have considered the IPB deposits as the bimodal siliciclastic subtype, although major differences can be recognized among them.
