Oct 20, 2014 The Metallurgy of Cyanide Gold Leaching An Introduction. Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative. Cyanidation Heap Leach Column leaching using cyanide solution to assess heap-leaching potential of gold bearing ores can be conducted using columns ranging from 100mm diameter x 1m high to 1.8m diameter x 10m high. All columns are made in-house according to the client/project specifications (for example, sectional columns,

Gold CIP, CIL System, Heap Leaching, Cyanidation Process . Gold Mine Heap Leaching Process. Crushed by jaw crushers and cone crushers to a certain particle size (30 50mm), raw ore is directly sent for heaping or granulated (to make finer particles agglomerate into coarse powder), and then transported to the ore heap site for heap construction. Gravity was the first method developed to recover gold from ore. But, currently there are very few deposits left that contain ores suitable for gold recovery strictly by this method. Cyanide leaching now recovers the greatest amount of gold and contributes to a variety of flowsheets from heap leaching to agitated leaching circuits.
