At the beginning of the Merrill-Crowe process, before leaching with cyanide takes place, amalgamation tailings are mixed with gravity concentration tailings, resulting in a product consisting of 150–350 mg kg −1 of mercury and 1.5–5 mg kg −1 of gold.
Gold Extraction Process. Sod ium cyanide has been used in the extraction of gold from ore for over a century. Today it is still considered the most efficient extraction method – with sodium cyanide used in the leaching process in most gold mining operations. Orica is one of the largest producers of sodium cyanide for the mining industry.

During this process, the cyanide leaching solution passes through columns filled with ore. The process is highly effective for removing gold from low grade ore. Resin Recovery Technologies Resin RIL (Resin-in-leach)/RIP (Resin-in pulp) In recent years, resin is replacing carbon as the gold recovery substrate of choice.
Cyanide leaching is the predominant process of gold extraction in large scale mining. Current initiatives for reducing the use of mercury in small scale and artisanal mining tend towards the cyanide technology as the only feasible alternative. Thus, the deliberate handling in consideration of the ...
The cyanide process is probably the best method yet devised for the chemical treatment of gold ores. In this process the ore is crushed and ground if necessary and the pulverized ore treated in wooden vats with a potassium or a sodium cyanide solution varying from one half to one per cent in strength.

CYANIDATION. Cyanide leaching is the standard method used for recovering most of the gold throughout the world today. The process originated around 1890 and quickly replaced all competing technologies. The reason was strictly economical in nature. Where amalgamation plants could recover about 60% of the gold present, cyanide could …

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.
Process. Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.

The net result is the complication of the chemistry involved in the cyanide process. Compare Cyanide VS Thiosulphate gold Leaching. No two ores are exactly alike. Therefore, it is practically impossible to predict how an ore will act during cyanidation, although broad generalizations can sometimes be made.
Xinhai gold extraction equipment can efficiently seperate gold and gangue by all slime cyanidation(CIP) ... Gold Heap Leaching Process
The gold mud containing high gold and silver will be re-smelted to high-pure gold ingot. At present, this process as the cyanidation gold extracting method is widespread used to process flotation concentrated gold ore.It is a high technological enterprise that integrated research , manufacture, sales and service .
silver from 1991 to 1995. Operations included the heap leaching of gold from ore, using a weak cyanide solution. Nevada Goldfields used seven processing ponds and one sediment pond to process the “pregnant” solution that contained the gold. After the closure of the mine, the approximate 10-acre Main Pit began to fill with water.
