gold mining process control using cyanide

Gold Ore Processing  ScienceDirect

Gold Ore Processing ScienceDirect

Gold roasting is a process, applicable to refractory ores and concentrates that contain sulfide sulfur, organic carbon, and potentially arsenic. Removal of these compounds is necessary to achieve high gold recovery (gt;90%) during cyanide leaching. Gold roasting is typically a metallurgical fluidized bed process.

Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.
