Copper and Bronze: The Far-Reaching Consequences of Metallurgy
Copper melts at 1,085 degrees Celsius, which implies the use of an enclosed furnace and of forced draught or the introduction of overpressure of air. By adding only 10 percent tin to the alloy (bronze), its melting temperature drops to 1,000 degrees Celsius, which still requires a furnace, but not forced draught.

In industrial applications, a fuming furnace is usually used to treat low-grade tin materials, and the treatment of tin materials is economically viable for the tin grade of greater than 1%(Liao et al., 2014; Zulhan and Gede, 2018). In the reduction smelting process, pyrite is mainly used as the sulfurizing reagent.

on reduction smelting of cassiterite In case the cassiterite ore contains Fe 3 O 4, the impact on Sn recovery in addition to the smelting temperature, time and the reducing agent, is the possible formation of Fe-Sn spinel during roasting [7]. However, this spinel can be reduced to Sn metal by smelting with strong reducing conditions.

Extraction of Tin/ Stannum-Tin-
Extraction of Tin/ Stannum. Extraction of tin consists of three parts, i.e. tin ore concentration, smelting and refining. Cassiterite is the main source of tin ore, with specific gravity of 6.8-7g/cm 3, density larger than most of gangue. Therefore, 90% of tin concentrate is mainly obtained from cassiterite through gravity separation.
