2020-8-15 The main sulfur-containing impurity present in coal, pyrite, has a higher permittivity and heats up faster than the bulk coal. Further, the magnetic properties of pyrite in coal are enhanced after heat treatment, which is conducive to the development of magnetic separation technology . Hence, microwave pretreatment of pulverized coal can stimulate the rapid pyrolysis of the pyrite in the coal and transform

ABSTRACT Wet high gradient magnetic separation (WHGMS) of an Egyptian coal sample was carried out to minimize its pyritic-sulfur content reaching 1.60% (2.9% total sulfur). Optimization of the process using the Boxmag Rapid separator included feeding rate, pulp density, applied magnetic field, and the canister loading %. This was conducted through the CCRD and RSM, using Design Expert 6.0 ...
