Heap leaching is very commonly used for low-grade ore, which would otherwise not be economical to send through a milling process. Following mining, transporting, and crushing to a consistent gravel or golf ball-size, the crushed ore is piled into a heap on top of an impenetrable layer, on a slight slope.

Oct 01, 2011 For the copper sulfide ore, copper recovery was independent of the crushing method since about 8090 of copper is recovered during the initial period of leaching . Recovery values were higher than those for the copper oxide ore samples, apparently due to the higher head grade, greater grain exposure and perhaps a more aggressive leach solution.
Apr 11, 2017 The sand tailing from the mill is treated by ammonia leaching and the slime tailing by flotation. Since metallic copper is malleable, it cannot be broken and pulverized as can the more friable minerals, and after first picking out the larger lumps or nuggets of copper by hand, crushing is done by steam stamps pebble mills instead of ball mills ...

Additionally assign to commission the pilot project on heap leaching of the MUF West Copper Oxide ore, whilst there improved the tonnage output of 0.5 tons to 20 tons in the heap leach plant, also worked as plant metallurgist SX-EW in the solvent extraction plant carrying out tests like the rise and drop tests. monitor the cathode produced ...
This mechano-chemical process can leach 97-99 copper directly on site, from concentrates as low as 5 copper in less than six hours. This makes it feasible for you to produce cathode copper from concentrate directly at the site rather than to sell the concentrate to a smelter. The ROL process can even leach copper from arsenic-ladden concentrates.
