Tin is released into the environment from both natural and anthropogenic sources. Metallic tin is a natural compound of the earth's crust, where it is present at concentrations between 2 and 3 mg kg −1 (Budavari 2001).Cassiterite (SnO 2) is the main ore of Sn; the other significant minerals of Sn are stannite (Cu 2 SnFeS 4) and …

The raw material of the placer tin (cassiterite) is often mixed with large stones such as waste rock and pebbles. These stones are completely free of tin minerals, which will affect the next stage of jigging separation work. Therefore, the first step in the beneficiation of placer tin (cassiterite) is to screen out these useless stones.

Tin is a silvery-white metallic element. The most important ore mineral of tin, cassiterite (tin dioxide), is formed in high-temperature veins that are usually related to igneous rocks, such as granites and rhyolites; it is often found in association with tungsten minerals. Tin is mined in 22 countries; China, Indonesia, and Peru are the three major producers.

The economic deposits of cassiterite are known in two types of geological occurrences – primary vein or hard-rock deposits and secondary placer. Processing of tin ores. Cassiterite is the prime tin mineral present in the earth crust followed by stannite, kesterite, mawsonite, and other tin sulphides (Benzaazoua et al., 2003; Xu et al., 2012).

1. Introduction. Historically, the dominant beneficiation strategy to recover cassiterite (SnO 2) from tin ores has been gravity separation (including jigs, spirals and tables), which could be followed by sulfide flotation for further upgrading (Bulatovic, 2010).As gravity concentration techniques are very sensitive to particle size, the …
