ABSTRACT:
A desirable metal such as gold in a low grade ore has its concentration increased by electro-kinetically separating gangue from other components in the ore to form a concentrate. Separation is effected by inducing movement of externally conductive particles upwardly and radially outwardly over the walls of a container enclosing a dielectric liquid within which the ore is initially contained. An electric field is established for this purpose between the container walls and an electrode positioned above the surface of the dielectric liquid.
