This article investigates the behavior of tin and antimony, both commonly present as trace elements in electrical and electronic waste, in secondary (i.e., sulfur-free) copper smelting conditions. The experiments were conducted in oxygen partial pressure range of 10−10–10−5 atm, covering the different process steps in copper smelting.
A New Pyrometallurgical Process for Producing Antimony …
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 …
Antimony smelting process generating solid wastes and …
A large amount of solid waste has been produced by the smelting processes in the Xikuangshan area. Specifically, the antimony smelting activities have historically produced 2 × 10 5 tons of arsenic-alkali residue (AAR), the majority of which has not yet been properly handled (Li and Liang, 2010). Currently, the amount of AAR in the Xikuangshan area is increasing by 5 × …
Process for smelting and separating antimony from gold
A process for smelting and separating antimony from gold includes the following steps: feeding auriferous oxygen powder obtained from a blast furnace by volatilization smelting into a reverberator, obtaining auriferous refined antimony by reduction smelting at a temperature of 800 to 1000 degrees centigrade, adding the auriferous refined antimony into an antimony white …
