METHODS FOR PROCESSING OF ANTIMONY …
concentrates are converted into antimony oxide for subsequent melting with a carbon reducing agent. For this purpose, firing is used "tightly" at 400℃ - 500℃ to convert antimony sulfide into non-volatile tetraoxide Sb 2 O 4. In these cases, the formation of antimony trioxide is unacceptable, since volatile trioxide leads to the loss
