Antimony process - American, Smelting Refining

The process for preparing antimony oxide which comprises softening antimonial lead thereby yielding an antimonial slag, reducing and concentrating said slag into an antimonial product containing from 65% to 80% of antimony, volatilizing antimony oxide from said product, recycling the residual metal until the copper content builds up to approximately 8%, then withdrawing the residual metal, cooling same …

Lead and tin removal from antimony metal by refining ...

The fire refining processes for antimony with the objective to primarily remove tin and lead as much as to receive respective residuals of 0.002% and 0.02% in the metal are multistage processes, associated with significant antimony losses during the slag phase, particularly when deep treatment for tin removal. This effect is observed due to the very close thermodynamic affinity of tin and ...

sumption of antimony. 4. The mineral processing of antimony Originally antimony was mined and hand sorted to effect con-centration. Since the bulk of primary production is in China, where labor is plentiful and cheap, surprisingly, hand sorting still finds a large application. However, in recent years, many other unit operations are used in the mineral processing of antimony. These include ...

Refining process for removing antimony from lead bullion ...

In using aluminum for antimony removal, the refining process is carried out at a temperature of 1300° F. The aluminum, upon addition, melts and is mixed into the bullion to react with the antimony to form an aluminum-antimony intermetallic which rises and is separated from the bullion as a dross. In this process, a considerable amount of lead is also physically entrapped in the dross.

REFINING OF NON-FERROUS METALS - EPrints

Arsenic and antimony, if pre-sent, are removed by using soda-ash and lime, the lime being added to reduce the wear and tear on the furnace lining. These latter ele-ments are, of course, removed after the nor- mal slagging process has been completed. Selenium and tellurium cannot be removed by fire-refining, although there are possibil-ities of some success using soda-ash under reducing ...
