pH Control in Solvent Extraction Circuits

The control of pH in solvent extraction circuits is an old technique but one which has a large potential for future use. The equilibrium position of any reaction which has hydrogen or hydroxide ions, either as products or as reactants, can be controlled by pH adjustment. Several examples of reaction types which are important in solvent extraction systems and which also show a pH dependence are

Introduction to Mineral Processing

Solvent Extraction Solvent extraction is a hydrometallurgical process. The organic solution returns to the extraction circuit to load more copper, thus repeating the cycle. The strip solution is pumped to the tankhouse where the copper is electrowon (electroplated). This solution then returns to the extraction circuit to repeat the cycle.

Solvent Extraction an overview ScienceDirect Topics

Solvent extraction is generally not used to treat in organics (acids, bases, salts, heavy metals). Solvent extraction processes are not designed to treat particular compounds, and extraction efficiencies and processing rates are lower when there are high concentrations of indigenous organic compounds (humic and tannic acids in soil).
