Abstract

Thermodynamic calculations performed on the computer by the proposed method determined the possibility of predicting the degree of sulfuric acid decomposition of iron oxide-sulfide associates of different composition and phase ratio. The high probability of galvanic interactions between the components of associates during their dissolution was shown.
