SULFUR DIOXSIDE UTILIZATION BY THE TREATMENT OF PYRITE- CHALCOPYRITE SULFIDE CONSENTRATES, COMBINING MECHANICAL AND METALLOTHERMIC PROCESSES	2017	6	.pdf	application/pdf	3479	171	45	= -693.86 – 0.59T kJ/mol Therefore, one can assume that due to the mechanochemical activation, the transformation of sulfides into sulfates promotes their aluminothermic reduction and extraction of sulfur in the form of CaS. Aluminothermic reduction was carried out with the samples prepared from the mixture of copper concentrate, aluminum powder, copper shavings, CaO and NaNO3[7,8].As a result metallic and slag phases were obtained, which were easily separated from each other after the cooling. In both c... 3FeSO4+10Al=3Fe+Al2S3+4Al2O3, (G = -4431.76 + 2.72T kJ/mol 3CuSO4 + 10Al = 3Cu + Al2S3 + 4Al2O3, (G = -4894.34 – 0.36T kJ/mol Most probably the following reaction takes place as well: Al2S3+3CaO=3CaS+Al2O3, (G = -693.86 – 0.59T kJ/mol Therefore, one can assume that due to the mechanochemical activation, the transformation of sulfides into sulfates promotes their aluminothermic reduction and extraction of sulfur in the form of CaS.
