ABSTRACT:
A process is provided for recovering a saline mineral from an ore containing the saline mineral and impurities. The process generally comprises the steps of separating a first portion of impurities from the ore by density separation, electrostatically separating a second portion of impurities from the ore, and magnetically separating a third portion of impurities from the ore. The process can further include the steps of crushing the ore and dividing the crushed ore into a plurality of size fractions before the above-referenced separating steps. Furthermore, in order to increase the efficiency of the separating processes, the process of the present invention may further include the steps of drying the ore to remove surface moisture therefrom and de-dusting the ore to recover valuable fines.
