primary processing of graphite

Fall 2011 America's EDM Forum

There are two primary molding methods used to produce graphite: The extrusion process which results in a high degree of grain directionality, and the isostatic process which minimizes grain direction by pressing the billet equally in all directions simultaneously.

Therefore a Carbon/Graphite or Graphite Material is truly the sum of its parts: Raw Materials + Processing + Imprengnant. Coatings Carbon components can be coated with Teflon™ or Pyrolitic Graphite to seal a surface and maintain chemical resistance.

Graphite production further processing - Carbon and Graphite

The final step in graphite manufacture is a conversion of baked carbon to graphite, called graphitising, i.e. heat-treating the material at temperatures in the region of 2600°C – 3300°C. During the graphitising process, the more or less pre-ordered carbon (turbostratic carbon) is converted into a three-dimensionally ordered graphite structure.

Individual pencils cut from the sandwich are ready for further processing. Any pencils with defects, such as uncentered leads or chipped wood, are discarded at this point. Next, each pencil is painted in a machine receiving from 4-10 coats of lacquer, depending on the desired quality of the finish and the color depth.

Flotation studies on low grade graphite ore from eastern India

A low grade graphite ore from eastern India was beneficiated by flotation to improve its quality. The ore was composed of 87.80% ash and 8.59% fixed carbon. Primary coarse wet grinding ( d 80 : 186 μm) followed by rougher flotation in Denver flotation cell using diesel as collector and pine oil as frother yielded a rougher concentrate.
