seperation of minerals from their waste

Gangue - Wikipedia

Early mining ventures, having relatively unsophisticated methods, often could not achieve a high degree of separation, so significant quantities of minerals found their way into the waste mineral dumps of mines. As the value of a mineral increases, or when new and cheaper means of processing the gangue to extract the ore are introduced, it may

Electrostatic Separation Procedure

Separation of minerals utilizing differences in their electrical properties may be carried out using an electrostatic separator. It will separate electrical conductors (minerals such as cassiterite and rutile) from those that are electrical non-conductors (minerals such as zircon and siderite). The principle of separation is that as the particles to be treated are passed through an intense
