COMPARATIVE LEACHING OF FILIZCHAY ORE AND PYRRHOTINIZED PRODUCTS OBTAINED FROM IT IN THE PRESENCE Fe2(SO4)3 AND FeCl3
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
