The occurrence state of gold-bearing minerals is mostly related to pyrite. Most of the gold-bearing minerals form inclusions in pyrite or silver-gold ore and pyrite form conjoined bodies. Other metal sulfide minerals such as chalcopyrite sphalerite galena stibnite etc. all appear in clumps and veins and part of the stibnite is oxidized

2. Sulfide suppression flotation process for high sulfide gold ore. The flotation process is one of the commonly used processes for sulfide gold processing. Because flotation can maximize the enrichment of gold into sulfide concentrates. According to the nature of high sulfide gold ore sulfide suppression flotation process is preferred
Nordwick 1996. Finally the alkaline sulfide solutions which are barren of gold can be recycled for further gold leaching or further processed with low temperature oxidation to sodium sulfate Na 2SO 4. This has been practiced in industry. The resultant sodium sulfate is further treated by purification and crystallization to Corresponding author
Sulfide precious metal ores are difficult to amalgamate using mercury due to the complex iron-sulfur-gold and other metals present which do not allow the gold to come into contact with the mercury. It is not uncommon for only 20 to 30 recovery of gold and silver by mercury amalgamation from sulfide

Barben Application Note - pH ORP Measurement in the Cyanide Leaching Process for Gold Processing
The gold ore must be pretreated to oxidize sulfide minerals associated with gold and to remove other minerals and chemical compounds that interfere in the cyanidation leaching process
the low costs associated with a heap process. A thin layer of gold-bearing refractory sulfide concentrate is coated onto any one of a number of supports such as coarse rock. The coated support rocks are placed in a heap or vat inoculated with iron and sulfur oxidizing microorganisms and allowed to biooxidize6. After biooxidation several
