Gold Ore Cyanidation Plant

In the cyanide production process, especially for ores containing more sulfide components, it is usually necessary to control the concentration of lime in the leaching operation. For the gold concentrate cyanide plant, the CaO concentration of the general control leaching process is between 2 and 510,000.

This research was carried out on aghdareh gold ore. the aghdareh mine and gold processing plant is located 32 km from takab city in the western azerbaijan province, iran, at 461765830n and 361763929e. the grade of gold ore is 3 ppm. also, cyanide leaching is used to process gold in the aghdareh mine . the main problem in extraction is achieving an acceptable separation of au from its ore.

Cyanide Use In Gold Mining Earthworks
Cyanide Use In Gold Mining Earthworks

Heap leaching in the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. the cyanide dissolves the gold from the ore into the solution as it trickles through the heap. the pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted.
