The details of product purification are discussed in the next section. 8.2.1 Centrifugation. Centrifugation is a method used for the separation of particles from a solution according to their size and density and rotor speed applied. It works using the principle that large and dense particles will sediment faster than small and light objects ...
Abstract Quartz (trigonal, low-temperature α-quartz) is the most important polymorph of the silica (SiO2) group and one of the purest minerals in the Earth crust. The mineralogy and mineral chemistry of quartz are determined mainly by its defect structure. Certain point defects, dislocations and micro-inclusions can be incorporated into quartz …
Such adsorbents include certain clays, such as diatomite, bentonite etc, as well as some synthetic products, such as silica gel, alumina oxide, activated clays, activated charcoal, zeolite etc. Mineral oil is also processed with the byproduct of alumina silicate production (crumbs), which cannot be used in the catalytic oil cracking process.

The initial purification process includes the process of crushing which releases the graphite flakes from the mineral parent rock. This helps improve the beneficiation efficiency. The size of the flakes and the carbon content of the sourced graphite are the most important factors in determining the final grade of the graphite.
