Breaking of ore from the size delivered from the mine into smaller and more uniform fragments to be then fed to grinding mills or to a leach pad. Dor. The final, saleable product of a gold mine.
The plant was commissioned and commenced production in August 1994. The annual design capacity was to produce approx. 500 kg of gold. The process plant was a simple conventional cyanide leaching method with the gold recovery by activated carbon. The gold ore produced by OMCO was sent to an overseas refinery for further processing.
Feb 27, 2019 The carbon in pulp method can also be called all-sliming cyanidation. It is a method in which activated carbon is put into cyanidation pulp to adsorb the dissolved gold onto the activated carbon, and then the gold is extracted from the activated carbon. The carbon in leaching method is developed on the basis of the carbon in pulp method.

Here the carbonate in the oxide ore is used to neutralize the acidic autoclave discharge slurry. The combined oxide slurry and autoclave discharge slurry are further neutralized with lime before treatment in the CIL circuit. The CIL circuit is used to concurrently leach gold from the ore and adsorb it onto activated carbon.
Using carbon allows the gold to be recovered on coarse pellets (16 mesh) of activated carbon. Activated carbon is made from coconut shells or peach pits to ensure the material is hard and doesnt abrade during contact with the solid particles in the pulp. The carbon is first conditioned to remove sharp corners and to remove fines.
