Recovery of Copper by Solution Mining Methods

2015-7-23  Solution mining is a mining practice that employs solutions (i.e. water or dilute acid) to recover a desired commodity from an ore deposit where it stands without also extracting the rock. There are essentially two types of solution mining: 1) in-situ and 2) in-place. In-place solution mining employs permeability enhancement techniques such as blasting or previous mining activities (i.e. block-caving) to fragment or increase the permeability of the rock prior to applying a leaching solution to liberate a desired commodity from the ore. In-situ methods

Leaching Solution an overview ScienceDirect Topics

The final pH of the leaching solution is higher than the original pH because of the alkalinity of the fly ash. Figure 1 shows the evolution of the final pH after extraction as a function of AD. Between acid dose 0 and 4 mol/kg, the pH decreases rapidly. Here, only small amounts of basic metal salts dissolve, so that the added acid is not neutralised.
