ABSTRACT:
In solvent-in-pulp extractions where aqueous leach slurries containing dissolved metal values and gangue particles of the silica, sericite or sulphide types are contacted with organic amine extractants, the loss of amine extractant to the solids is decreased sharply by pretreating the slurries with organic non-ionic hydrophilic material which is adsorbed by the gangue solids and decreases the affinity of the gangue solids for the amine. A combination of inexpensive materials has been found to be most effective. Crud formation is substantially avoided and the separation of phases is facilitated.
