Extraction of Antimony

Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated. The concentrate is then reduced to metal by smelting with wrought iron in pots, in reverberatory furnaces or sometimes in blast furnaces,

Process for leaching sulphide concentrates of the ...

The concentrates are repulped into an aqueous ferrous sulphate solution with an established and controlled solid-liquid ratio which is thereafter oxidized by an oxygen containing gas in a reactor, thereby oxidizing the sulphides to sulphates, precipitating iron as ferric arsenates and antimoniates and yielding a lixiviation pulp in which the solid phase contains the iron, antimony and arsenic as well as the insoluble sulphates

Metal Sulfides - an overview ScienceDirect Topics

Nonferrous metal sulfide concentrates containing arsenic, antimony, and bismuth can be treated prior to smelting by either pyro- or hydrometallurgical routes to recover these elements as by-products. During the thermal treatment, however, a minor part of these elements will remain as an undesirable impurity in the raw nonferrous metal produced.
