In the present work oxidation of Filizchay polymetallic ore and pyrrhotinized product in solution with trivalent salts (Fe₂(SO₄)₃, FeCl₃) of iron was studied. The influence of temperature, concentration of solvent ions, acidity of a solution and experiment time on dissolution process was studied by laboratorial experiments. Derivatographic analysis of pyrrhotinized product with Fe₂(SO₄)₃and FeCl₃was conducted, according to the results kinetic parameters were calculated and activation energy was found
