Oxide Copper Leach Modeling

In the study of copper oxide leaching, the consumption of acid is too high to be explained by copper release alone, particularly in the later stages of leaching. An independent term due to gangue materials has, therefore, to be taken into account for R, the net rate of generation of acid in the column. In this investigation R is represented by three different constants corresponding to the ...
