Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery. The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently leach low grade pyritic ores. Perhaps there is some room here for a pretreatment, to ...

The following gives an overview of how copper is extracted from its ore and converted into pure metal. Mining. The ore is removed from the ground in either open pit or underground mines. Underground – sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Openpit – 90% of ore is mined using the open pit method. Ores near the surface ...

· In this paper, the use of seawater in leaching of the chalcopyrite ore samples with copper grade of % in acidic media is investigated. Different leach solutions were prepared using different acids (H 2 SO 4, HCl and HNO 3) with and without seawater. Cupric chloride and ferric chloride were added as oxidant in the leaching process.
Primary gold mineralization is typically associated with pyrite/chalcopyrite sulphides and quartz/dolomite gangue. There is a correlation between vein frequency and gold grade. Weathering locally modified the mineralization, to depths typically up to 200m, with the boundary between oxide and primary mineralization being irregular.
