Sulfur fixation and reduction roasting of stibnite for ...

2019-12-1  The direct sulfur fixation and reduction roasting of antimony sulfide (Sb 2 S 3) were investigated for antimony extraction, based on the combination of metallurgy and beneficiation.Zinc oxide (ZnO) and carbon, used as the sulfur-fixing agent and reductant, respectively, were roasted with Sb 2 S 3 to form Sb metal and zinc sulfide (ZnS). The products were separated by gravity separation and ...

A New Pyrometallurgical Process for Producing Antimony ...

2014-6-6  Antimonial dust is a by-product of lead smelting and an important material for extracting antimony. A new pyrometallurgical process for producing antimony white from the antimonial dust is reported. The process mainly consists of three steps, which are reduction smelting, alkaline refining, and blowing oxidation. First, the reduction smelting of antimonial dust is carried out in an oxygen-rich ...

Characterization of antimony-containing metallurgical ...

1. Introduction. Owing to the scarcity of Sb reserves and growing Sb consumption, there is an increasing sense of urgency to recover Sb from metallurgical residues and end-of-life products (EC, 2017; Dupont et al., 2016; Karlsson et al., 2018).The current Sb recovery from end-of-life products merely concentrates on lead-antimony alloys from waste lead-acid batteries ().

US Patent for Process for the recovery and separation of ...

1991-1-29  Fume generated by roasting speiss is contacted with an oxygen-containing gas at an elevated temperature for a sufficient time to product arsenic and antimony products which may be separated from each other by means such as condensation. Further, in the roasting of antimony-containing phases (such as speiss) the presence of arsenic can enhance the volatility of the antimony.

Separation and Recovery of Antimony from High Arsenic ...

The recovery of antimony from high arsenic-bearing flue dusts was carried out by a selective oxidation roasting process using MnO 2, in which the arsenic was removed through a volatilization and antimony was oxidized to Sb 2 O 4 staying in the roasted products. In a certain range, the MnO 2 additive has an active effective on the arsenic volatilization for the reason that structures of some ...
