Abstract
A SIMPLE method has been devised for the separation of minerals with a relatively high electrical conductivity in rock powders. It is based on the selective deposition upon these minerals of metallic iron, in an electrolytic cell, enabling them to be separated from the non-conducting grains with a magnet.
