Gold Ore Cyanide Process In Cameroon

2020 9 23 Gold cyanidation also called cyanide leaching is a process used to extract gold from raw ore taken from the ground It uses cyanide to dissolve the gold within the rock which itself is not soluble in cyanide

Cyanide Process Gold Cyanidation Process Gold

Now the gold is soluble This method of making soluble gold is known as leaching In the process of leaching a dilute form of sodium cyanide is added into the ore containing the gold Since gold is soluble after the leaching process it is free to move through the membrane while the rest of ore cannot pass through the membrane Lime is added
