Tin processing
In a typical reverberatory process (the most commonly used), the furnace is heated to 1,300–1,400 °C (2,375–2,550 °F) for a period of some 15 hours, during which it is stirred frequently, especially during the later stages. This process produces a pool of molten tin, on top of which floats a slag containing most of the unwanted impurities.

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.

Before leaching, Bangka tin slag (BTS) was characterized through XRF. The slag was then 900°C-roasted, quenched, and dewatered. Next, BTS underwent a sieving process with size classifications of +100, -100+150, -150+200, -200+250, and -250 mesh. After that, the -200+250 mesh slag was leached with 8M NaOH.
Tin Metallurgy | SpringerLink
Tin ore has very low grade (tin content 0.005–1.7%), so it needs to experience mineral processing to generate the concentrate with tin content 40–70%. Gravity separation is the main process for tin ore mineral processing. There are other physical processes such as flotation and leaching.
