Abstract
A process is provided for separating minerals from a mixture of minerals having different densities. The minerals are provided in the comminuted state to liberate the minerals one from the other, following which the minerals are slurried in an aqueous solution of lithium metatungstate selected to provide a density between the densities of the minerals to be separated, whereby the minerals having a density greater than that of the solution will sink and the minerals having a density less than that of the solution will float.
