Sažetak
The research results are demonstrated on the electrical resistance and beginning softening temperature of the highash coals of Saryadyr, Borly and Zhamantuz deposits (Republic of Kazakhstan). Such parameters of the charge in the ore-thermal furnace provide a low fraction of the charge conductivity, and thereby contribute to the release of a main energy fraction in a reaction zone of the furnace where a metal is formed. The research results showed that a value of the electrical resistance of the charge at the non-isothermal heating to the high temperatures depends on the chemical and mineralogical composition of the charges, and on processes of phase transformations in a sample.
