PROCESS TO MANUFACTURE PURIFIED CARBON FROM BROWN COAL AND PROCESS LINE THEREFORE Russian patent published in 2008 - IPC B03B7/00 C10L5/04 

FIELD: mining industry.

SUBSTANCE: process to manufacture purified carbon from brown coal implies treating loosened batch mixed with water in cavitation apparatus, which provides for disintegration of organic portion of carbon-containing mixture down to particles of less than 20 mcm. Then, resulting water-carbon mixture is directed to separation tank for sedimentation of mineral mass, which is regularly dumped. From the separation tank, mixture is fed to electrophoretic separation device, out of which paste-like carbon-containing mixture is extracted. Cavitation apparatus power is selected in such a way so as to obtain inorganic particles larger than the organic ones in the water-carbon mixture. Impact cavitation action is applied to continuous slurry flow, while water-carbon mixture is held in the separation tank for at least 20 sec.

EFFECT: high efficiency; production of low-ash purified carbon from brown coal.
