gold processing
High sulfide gold ore refers to a certain gold ore with 20% -30% of gold wrapped by sulfide (mainly pyrite). Because most of the gold in high-sulfide gold ore exists in the form of sulfide-encapsulated gold, when using direct leaching process, the consumption of gold leaching agent and cost of gold leaching production will increase, and gold processing efficiency is not good.

The SI prohibits processing and washing plants, ore stockpiles, slime dams or setting ponds constructed within 500 metres from river banks or highest flood line of any water source. In its report copied to various government departments and security arms, CRD implored responsible authorities to clamp down on illegal gold processing in Penhalonga and surrounding communities.

Some of the metallurgical relationships that must be considered from the testwork program as follows: ore grade relationship to gold recovery, crushing and grinding parameters and their relationship to the ore variability in the ore body, effect of other minerals on the process, minerals and/compounds that negatively impact processing cost such as oxidized copper minerals and organic matter.

This is a piece of gold ore from the famous Witwatersrand gold deposits of South Africa. The ore consists of conglomerate pebbles mostly of quartz, in a sandy matrix, with abundant pyrite in the cement. The gold, which occurs in the cement but not in the pebbles, is closely connected with the pyrite and is not visible to the naked eye.

If your gold is unrefined, your best option may be to ship it to a refiner. These processes may be challenging and cost-prohibitive for you. Another issue is that if you try to refine your own scrap, you may only recover the gold and not the other precious metals that may be present, such as silver and platinum.

When gold is mined, it must be extracted from its surrounding materials. Gold extraction refers to the methods used to remove gold from its raw state in gold ore. A number of processes are employed to achieve extraction, including separating the gold from its surroundings by physical force, exposure to heat, or chemical means.

At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost
