Graphite for Industrial Use

Home » Technology » New Technologies » Metal and Metalworking Industry » Graphite for Industrial Use

Process

A process for the production of different grades graphite.


Uses

Wide ranging uses in crucible, pencil, electrical and foundry industries.


Salient Features

Simple and low cost process. Different grades of graphite are produced in down stream steps. Recovers as much as possible in flake size in flaky raw graphite. The process can treat flaky, as well as amorphous variety.


Environmental Considerations

There should be well planned disposal of waste and effluents.


Scale of Development

The process has been developed on 20 tpd continuous run pilot plant scale.


Commercialisation Status

  • A 10 tpd graphite beneficiation plant for Patna State Mining Company at Titlagarh, Orissa,
  • Process know-how, technological flow-sheet and consultancy given to M/s. BSMDC for a 150 tpd graphite beneficiation plant
  • A plant to product 50 tpd crucible grade graphite in Banswara, Rajasthan running since 1982.

Major Raw Materials

Graphite ore, Cresylic acid, Pine oil, Sodium silicate, Lime.


Major Plant Equipment/Machinery

Crusher, Distintegrators, Rod mills, Conveying systems, Concentrating tables, Conditioners, Flotation banks, Reagent feeders, Thickeners and pumps, Rake separators.


Techno-Economics

A 40 tpd plant will require a capital investment of Rs. 120 lakhs.
