Three Stages Of Ores

Stages of hydrometallurgical processes

· Process Stages Heap leaching ore is crushed piled onto an artificial pad and then solution is trickled on it [9]• A major advantage of heap leaching is the elimination of expensive milling operations since the ore body need not be crushed to sizes much smaller than 20 to 25 mm [4] Figure3 Heap Leaching 9 10 Process Stages Vat Leaching The ore meant to be leached is loaded into vats
