A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.

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.

Water samples from Xikuangshan (China), the world largest antimony (Sb) mine with a Sb mining and smelting history of more than 200 years, were analyzed. These water samples ranged from stream water in the vicinity of the mining and smelting area that received seepage from ore residues to the underground mine-pit drainage.

Excessive mining and smelting lead to a significant release of Sb to the water and soil environment (Casiot et al., 2007, Majzlan et al., 2016, Wen et al., 2016, Yang and He, 2015). Disorderly stacking of antimony smelting residues is one of the main sources of antimony pollution (Liu et al., 2010). Therefore, revealing and controlling the Sb ...

The leading antimony mineral is stibnite In smelting stibnite ore two processes are available, precipitation and roasting-reduction The former is suited, only for high-grade or As low-grade ores are more common than high-grade, roasting-reduction is of greater importance than precipitation In the roasting process the aim may be to leave the oxidized antimony in the ore, or it may be to ....

The invention relates to a smelting production method of antimony trioxide. The method includes the following steps of: raising the furnace temperature of a smelting furnace to 700DEG C-900DEG C, pushing an antimony ingot into the furnace by a mechanical arm and then stopping heating, and introducing air into the furnace body, letting the oxygen in the air and the antimony ingot undergo an ...

The smelting of crude antimony requires a high temperature environment to allow the oxidation reaction of antimony sulfide and subsequent desulfurization [5]. In this way, the antimony oxide containing arsenic, lead, and other impurities (namely, crude antimony) is created and to remove the arsenic impurity, further refining is required.

In addition, they report no smelting since 1991. If you still work at a smelter, work with management to make certain the antimony levels are below the OSHA standard. Avoiding excessive or unnecessary dust exposure will help prevent occupational lung disease.

Antimony is used in lead bullet alloys - IIRC, linotype is about 84% lead, 12% antimony and the balance is tin. One issue with melting and casting is that when the metal does finally melt, it does so immediately and you can have a potentially dangerous situation if you aren't prepared for that event.
