At present, most of the tin concentrate sent to the smelter is the product of shaker beneficiation. Jigs are mostly used for the purification of coarse and medium-sized cassiterite. The spiral concentrator is used to recover cassiterite with a size of 0.074~1mm. For the sludge smaller than 37μm, it is mainly purified by centrifuge and sluice box.Web

Cassiterite is the only economic tin-bearing mineral from which tin metal is extracted [6]. Due to the compact embedding and fine-grained distribution of cassiterite in iron-bearing minerals and gangue minerals, it's difficult to recover tin from the Fe-Sn skarn iron ores using the present physical mineral processing methods, including ...Web

Because the density of cassiterite is higher than that of co-existing minerals, the traditional beneficiation process of tin ore is gravity beneficiation. With the passage of time, the granularity of cassiterite in the selected ore has been continuously reduced, so that the cassiterite flotation process has emerged.Web

The above cassiterite processing methods can produce tin concentrates with a tin content of 60% or higher, and a tin recovery rate of 70% or higher. Finally, the extraction of tin can be carried out according to the actual situation. The cassiterite processing is often determined by ore properties, beneficiation plants, and budget.Web

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 recovery of …Web
