"This ore is mined from a quartz vein which is refined by small seams of graphitic clay material, and the walls of the vein consist of a sort of graphitic shaley material. The above graphitic materials break down under treatment into a rather peculiar clay which was called primary colloidal slime. The milling process in use consists of stamp milling followed by the separation into sand and primary slime in Dorr Duplex Classifiers. The primary slime overflow from these classifiers, which is all practically thru 220 mesh, is thickened and treated by flotation. Normally and with a good supply of …
