Abstract
There is described a process for separating from a mixture of mineral components at least one of the components. The process comprises the steps of (a) dispersing the mixture of mineral components in water so as to form an aqueous suspension containing said mixture of mineral components, (b) mixing together said aqueous suspension and a non-polar organic liquid in which there has been dissolved or suspended an anionic collector for at least one of the components of the mixture of mineral components, the volume ratio of said aqueous suspension to non-polar organic liquid being controlled and the conditions under which said aqueous suspension and non-polar organic liquid are mixed together being such that only a small amount of energy is dissipated therein in a short time in order to effect the mixing together thereof and one liquid is uniformly dispersed in the other but a stable emulsion is not formed and (c) thereafter separating, or allowing to separate, the two liquid phases.
