Abstract

A method for improving coal, in which a raw coal is treated with a metal-containing compound, in order to increase the magnetic susceptibility of one or more impurities susceptible to treatment with metal-containing compound, thereby allowing separation of these impurities by magnetic separation, characterized by the operation of pretreating the carbon by heating it to a temperature and for a period of time, both sufficient to meet or exceed a relation of time and temperature expressed as: ** (see formula) ** Where d is the time in hours and t is the temperature in degrees celsius, not being less than about 95º c, and where k is at least about 0.5.
