A highquality flake graphite product that closely resembles natural flake graphite can be made from steelmaking kish. Kish is a largevolume nearmolten waste skimmed from the molten iron feed to a basic oxygen furnace, and consists of a mix of graphite (precipitated out of the supersaturated iron), limerich slag, and some iron.
The seal oil system may be combined with the lube oil system if the gas does not adversely affect the lubricating qualities of the oil, or provided the oil made unserviceable by the gas does not return into the oil system. Figure 5. There are two methods of combining lube oil and seal oil systems: booster or combined systems.

In graphite flotation, a variety of nonpolar oils such as kerosene and fuel oil are generally used in combination with frothers such as pine oil or higher alcohol. In many respects, graphite responds to flotation in a similar way to coal or molybdenite.
Graphite is mined by both open pit and underground methods. Graphite usually needs beneficiation, or the treatment of raw material to enhance its chemical or physical properties. This may be carried out by handpicking the pieces of gangue (rock) and handscreening the product, or by crushing the rock and floating out the sample of graphite.
