Abstract

There is studied the possibility of increasing the quality of cryptocrystalline graphite which is connected with searching for more complete opening, the aggregates of graphite and ash admixtures. To achieve this purpose, there was used mechanoactivation and microbiological processing. The developed technology including mechanoactivation, sintering, chemical and microbiological processing, allows to reduce the ash content of cryptocrystalline graphite from 20-25 down to 1-10 % depending on the initial quality and the area of using graphite
