What Is the Percolation Leaching Process?

What Is the Percolation Leaching Process?

May 11, 2020 · The percolation leaching process is a kind of leaching method in which the leaching agent penetrates the fixed ore bed in a topdown or horizontal manner by means of gravity or pressure. It is the key to ensuring the economic benefit of the concentrator to choose the appropriate percolation leaching .

A model for the leaching of oxide ores is developed and correlated with laboratory tests for percolation leaching of copper oxide ore. Using the model, recovery of metal values and lixiviant concentration of the effluent solution at any time may be evaluated. For the copper oxide ore, a simplified version of the model is examined for the leaching mechanism consisting of (1) a surface flush reactio

percolation leaching of copper ore

Percolation Heap leaching, (see Mular et al. pp. 1571–1630, loc. cit.) is very widely applied to the ores of copper and precious metals, but percolation is also conducted on a smaller scale in batch tanks or vats and in continuous or dump extractors. In the heap leaching of lowgrade oxidized gold ores, for instance, a dilute alkaline solution of sodium cyanide is distributed over a heap of ...
