Antimony Recovery from End-of-Life Products and

08/02/2016· Antimony is produced from stibnite ore (Sb 2 O 3) which is processed into antimony metal and antimony oxide (Sb 2 O 3). The industrial importance of antimony is mainly derived from its use as flame retardant in plastics, coatings, and electronics, but also as decolourizing agent in glass, alloys in lead-acid batteries, and catalysts for the production of PET polymers. In 2014, the European

Extraction of Antimony

With oxidised ores recovery of antimony is incomplete unless anthracite is added to the charge. Thus, treated at 900° C. without anthracite, only the antimony present as sulphide is recovered, while with anthracite almost complete recovery has been effected. Using an ore containing 3.3 per cent, antimony, partly sulphidic and partly oxidised, the average anthracite consumption was 15 to 20

Electrolytic recovery of antimony from natural stibnite ore

01/11/1996· After dissolving the ore in concentrated acids, tartaric acid is added to the solution before dilution with water, to avoid the hydrolysis of antimony; tartaric acid alone dissolves some oxidized antimony minerals. 3.2.3. Sulphuric acid leaching Concentrated H2SO4 is an efficient solvent for the decomposition of sulphide and oxide antimony ores [19] and gives good recovery when used alone

US3883345A Process for the recovery of antimony

A process for the recovery of antimony values from a material containing the same is described wherein the material is subjected to a controlled roasting step, the resulting calcine leached with an alkaline solution to extract antimony values and the antimony-pregnant solution acidified to precipitate antimony values. The roasting step is carried out in a reducing environment thus assuring
