Abstract

The solid pyrometallurgical calcination product containing antimony was dissolved in H2 SO4 under conditions that ensured a high extraction of the oxidized antimony compounds into the solution. The key conditions were [H2 SO4 ]-180 g/l, duration - 2 hours, temperature - 80 º?, T: J = 1:6, and a rotation speed of 400-450 rpm. The study determined a high degree of antimony dissolution is possible and found the optimal points for the proposed process.
