Behavior of Tin and Antimony in Secondary Copper Smelting ...

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.

How to melt antimony - Gunloads.com

Nov 25, 2018· The trick is to submerge the antimony chunks in the melt or it just floats on the surface. I perforated the bottom of a can that fits the pot and made a wire handle to move it up and down for agitation while dissolving. I wouldn't mess with antimony dust. To melt antimony I've used a charcoal furnace with blower - more trouble than it was worth.

Smelting - an overview | ScienceDirect Topics

Antimony, arsenic, and tin. Depending on the smelting regime employed, the operator can drive the majority of these elements either in the bullion metal or in the slag. In most cases, these elements are recovered in the lead bullion and subsequently used to produce alloys, although there will always be some metal loss to the slag fraction.

MIT's accidental smelting discovery unlocks the potential ...

The traditional method of producing antimony metal is through heat smelting. However, researchers at MIT claim to have accidentally stumbled upon a new method of smelting using electrolysis rather than heat. Research was funded by the US Department of Energy, the Advanced Research Projects-Energy (ARPA-E), and French energy company Total SA.

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 ...
