The development of dry mineral process is a priority issue in the mining industry aimed at saving raw
materials and energy resources. In spite of this, industrial coal beneficiation technologies are currently
based on water processes although use of such wet processes entails certain environmental and
economic consequences. The development of an efficient dry coal beneficiation technique becomes
possible on the condition of preliminary heat treatment of coal without the access of air and
subsequent ash removal through dry electromagnetic separation. These chemical transformations will
open up new processing opportunities.
In this contribution, we report the results on a study performed on sample of high-ash Kuzbass coal
collected from the Karakan coal deposit in order to study the properties of coal under thermal and
chemical conditioning for dry beneficiation .
