Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold per ton of rock. In all methods of gold ore refining, the ore is usually washed and filtered at the mine, then sent to the mill.
ContactThere are four main processes of gold extraction: Mechanical processes for preparing and washing the ore. Preparation of the ores, with simultaneous or subsequent amalgamation. Chemical extraction-processes. Smelting of certain ores.
Contact2021-2-24 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
Contact2015-9-15 Whole-of-ore CIL extracted between 28 and 79 percent of the gold in feed, with an average of about 61 percent. These results would indicate there is some degree of refractory gold, which would require alternative processing to recover.

Contact2020-12-1 Under neutral conditions, the gold extraction rate from refractory ore reaches 80%.
Contact2000-12-1 Both of the suggested mechanisms were found to play a role in enhancing gold extraction, with the controlling mechanism most strongly dependent on the ore's mineralogy. The preg-robbing characteristics of the ore and the cyanide concentration used for gold leaching were also important factors in the enhancement of gold extraction.
ContactAmongst these methods, cyanidation is the most common method used in the leaching of gold from the ore. This process involves the dissolution of gold containing ores in dilute cyanide solution in the presence of lime and oxygen.
ContactFrom received gold-containing eluate it is extracted gold by decomposition reaction or by electrochemical method. Additionally decomposition reaction is implemented by metals such as magnesium, zinc or iron, or by sulphides. Then it is implemented recovery of heavy-basic anionite by solution of mixture of sulfite and sodium sulfide and ammonium.
