dc.description.abstractInvestigations of the slag, obtained from the non-ferrous metals, are of great importance to expand the raw material base for complex utilization, to increase the extraction of useful elements and to protect the environment. The kinetic of reduction of the waste fayalite by calcium carbide was investigated for two ratios of 1:1 and 1:10. Thermogravimetric analysis was carried out. Activation energy was determined, the maximum for the ratio 1:1 was 18.81 kJ/mol, and for ratio 1:10, Ea = 21.31 kJ/mol. The rate constant is also determined and the equations for the two defined temperature ranges were respectively derived. The maximum rate of reactions for the two mixtures is obtained, for the first mixture υ = 1,7176.10-3 mg/min at a temperature 1221 K, and for the second mixture the maximum rate is υ = 1.2339.10-3 mg/min at 1230 K.
