Cyanide Heap Leaching Processwonder Cement Salary

a brief note on the heap leaching technologies for the,the foremost application of the tank leaching method is the extraction of aluminum at low pressures and temperatures .the heap leaching process is obviously suitable method and has lot of advantages as mentioned above: however, as per the environmental concern it has some draw backs, such as time consumption, water loss, accidental leakages of pregnant leach solutions, slow heap leach kinetics,.gold fields - mineral resource and mineral reserve,the north heap leach was commissioned in 1998 to process the initial high porus ore. phase v heap leach pad construction was completed in 2009 and a further three phases of heap leach pad construction have been accounted for in the lom plan. as the mine gets deeper so the percentage of weathered ore amenable to heap leaching decreases..
