A Brief Note on the Heap Leaching Technologies for the ...
In this paper, the authors reported the heap leaching plan and design for copper leaching by the mathematical model named MINLP and BARONGAMS solver. They studied different primary variables such as acid price, variable costs, and ore grade quality. These were highly effective on the production capacity of copper. It is possible to recover 60% of copper through heap bioleaching . The authors ...

23/07/2013 · Though minor amounts of the primary copper sulfide minerals, chalcopyrite and bornite, are present, the plant is designed to leach the secondary copper minerals. The heap is formed with multilift stacking. This entails stacking ore to a depth of 8–10 m, leaching for a time, followed by placing another 8–10 m of ore (a lift) on top of the first layer with more leaching; .
