minerals separated by screening

Minerals and other materials are separated electrostatically through the difference in degree of electrical conductivity of the particles, however many minerals, metallic and non metallic, and other materials, accumulate a surface frictional charge through rubbing together in transit conveying or through coming into contact with various metals
