ABSTRACT:
Kish graphite can be separated from fume in kish graphite-fume mixtures and can be recovered as a clean usable product by screening the kish graphite-fume mixtures to separate the mixtures into a screen overflow and screen underflow. The screen overflow is mixed with a solution of a washing agent and a surface active agent. The mixture is stirred to thoroughly "wet" the surfaces of the kish graphite. The mixture is filtered. The kish graphite is recovered as a filter cake. The effluent which consists of the washing agent, the surface active agent and fume, is passed to waste. The kish graphite retains its integrity through the separation, recovery, and cleaning steps.
