The objective is to design a stockpile that will minimize the grade variation of stockpile The efficiency of an ore processing unit depends on the consistency of the characteristics of raw material entering the plant When the mined ore is highly variable in quality the only way to ensure Mar 24 32 As a rule of thumb open pit mining can process ore for $10 per tonne and where the ore grade is more than double that at $20 per tonne results would be

The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters Flotation tailings are then leached for further gold recovery The ore processing rate is approximately 35 million tonnes per annum Typical head grade is approximately 08 gram per tonne gold and 011 per cent copperSince inception of the mine refractory ore from the copper production process was surface stockpiled KCM has now developed a process to extract copper from the refractory ore stockpile The company also produces several by products including sulphuric acid produced from the smelting process which is largely consumed in the leaching process

Ore examples shown above are from the high grade native copper oxide stockpile that has been found to contain significant quantities of cuprite and chalcocite All details shown above highlight high grade copper ore estimated between 8 10 Cu containing malachite azurite chalcocite cuprite and native copper mineralscopper ore will therefore also produce close to 200 000 tonne/day of tailings Low grade stockpiles contain ores that are sometimes used for blending during normal operations However they can contain ores that have uneconomical grades at the time of mining but have the potential to be economic if metal prices improve They may be economic but
