US5139752A Method for extraction of gold and silver from . From an ore containing gold and silver, the gold and silver are extracted by a method which comprises pulverizing the ore and bringing the pulverized ore into contact with an elemental halogen, a halogenated salt, and an organic solvent thereby converting the gold and silver into.
These ores occur in much larger accumulations, the iron is easier to extract and the metal is not contaminated with sulfur, If pyrite contains 0.25 gold and the gold price is $1500 per troy ounce, then one ton of pyrite will contain about 73 troy ounces of gold worth over $109,000.

Gold CIP process (carbon in pulp) is one of the gold . 3．Gold CIP method is not suitable for gold ores with high silver content Experts in the United States have tested that when the gold ore contains than 30g t of silver, it is not suitable for CIP method 4．Since sodium cyanide cannot be recycled, it consumes a lot and pollutes the environment (PS.
The implementation of an “intelligent” process control system helped significantly in achieving steady low roasting temperatures, thus obtaining high gold recoveries of 92 to 93 percent. Under these conditions, several roasting campaigns with high-arsenic-containing ores were conducted, which resulted in a significant decrease in gold recovery.
