Beneficiation of Graphite - Stratmin Global Resources ...

Beneficiation is any process which reduces the amount of unwanted ore or waste from the target metal or mineral which in this case is Graphite. At the lowest level this can be achieved by picking out lumps of raw material that looks high in Graphite or on a larger scale by not processing raw material thought to be low in Graphite.

HB graphite grading scale - Pencils

The HB graphite grading scale is used to determine the hardness and the darkness of pencils. The 'H' in the HB scale stands for hardness. The higher the number next to the 'H', the harder the pencil lead inside is. The hardness is determined by the amount of clay added to the pencil leads during production, the more clay then the harder the pencil.
