Application of SART to Heap Leaching of Gold-Copper

Therefore, if the ore has 40 g/t of cyanide-soluble copper, then the minimum quantity of cyanide required for copper leaching is 0.1 kg NaCN/t. If the quantity of copper extracted increases to 300 g/t then the cyanide requirement increases to 0.7 kg NaCN/t. Viewed another way, since the 3 moles of cyanide that are complexed with each mole of

The progression of metallurgical testwork during heap

Heap leaching is used extensively for the processing of copper and gold ores. Low capital and operating costs and simple atmospheric leach processes make heap leaching suitable for low- grade ores and small deposits. Disadvantages include low recoveries, long ramp-up times, large footprint and acid-mine drainage of wastes3.

Reasons for Copper Ore Sorting cont. • Pre-concentrate feed into high-grade and low-grade stockpiles: Optimize multiple process streams i.e. send ore to either mill, heap leach or smelter. Allows smaller mills to be built or increase capacity of an existing mill. Manage ore blending programs more effectively.
