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 ...

Heap leaching SX-EW is a method of extracting pure copper from oxide ore by placing the crushed ore on a pad in a heap and spraying the leaching solution, sulphuric acid, over the heap. The acid trickles through the heap and dissolves the copper mineral into solution. The leach solution collects at the bottom of the pad in a collection pond.

Recently, HGI has been helping a copper heap leach facility in Arizona with its end ...
Abstract The bioleaching of low-grade copper sulfide ore and the selective extraction of copper were investigated. Lix984 dissolved in kerosene was used as extractant. The results show that it is possible to selectively leach copper from the ores by heap leaching. The copper concentration of leaching liquor after 250 d is 2.17 g/L, and the copper concentration is 0.27

The geotechnical characteristics of the ore are important in understanding the kinetics of a copper heap leach. These characteristics can indicate potential problems and can be used to determine the semi-quantitative changes in field kinetics as compared with column kinetics. The application of this approach allows a more rigorously based determination of scale up factors
