The iron precipitation method is used to produce antimony metal from concentrated antimony ores or from the crude antimony issued from the liquation process In this process, scrap iron is added to molten Sb 2 S 3 to displace the antimony in order to form antimony ,
In view of increasing emissions of antimony (Sb) into the environment due to industrialization and consequent carcinogenicity, it is essential to remove this metal from the ecosystem Antimony and arsenic (As) are analogs Although numerous studies examined arsenic removal, few reports are available on Sb removal In this review, various Sb removal techniques are described to understand how .
The process of extracting tin from tin ore varies according to the source of the ore deposit and the amount of impurities found in the ore The tin deposits in Bolivia and England are located deep underground and require the use of tunnels to reach the ore

POLYESTER FIBRE: Fibre manufacturing process: Today over 70 to 75% of polyester is produced by CP( continuous polymerisation) process using PTA(purified Terephthalic Acid) and MEGThe old process is called Batch process using DMT( Dimethy Terephthalate) and MEG( Mono Ethylene Glycol) Catalysts like 5b3O3 (ANTIMONY TRIOXIDE) are used to start and control the reaction
The industrial methods for refining antimony are roasting and reduction with carbon or direct reduction of stibnite with iron , An emerging application is the use of antimony in microelectronics , Production process The extraction of antimony from ores depends on the quality and composition of the ore
For roasting sulphide ores two methods are used, viz, simple roasting yielding mainly antimony tetroxide, and volatilisation roasting yielding mainly antimony trioxide In the former, reverberatory furnaces are employed, the flue gases passing through a condensing plant for the recovery of any antimony trioxide that may be formed

A method is described in which arsenic, antimony, and tin are separated from most of the lead in babbitts, type metals, solders, and the like, by digestion in hydrofluoric, nitric, and sulfuric acids, and from most of the copper, zinc, lead.
A more efficient method uses a reverberatory furnace and continuous liquation, however a reducing atmosphere must be provided to prevent oxidation of antimony sulfide and loss by volatilization The oxide volatilization process to recover additional antimony usually treats the residue, containing 12–30% antimony
