Recovery of tin bearing minerals from hard rock deposits involves multiple processing stages. Mineral Technologies can aid the processing of historical tin tailings by designing a suitable gravity circuit comprising spirals and wet shaking tables that will recover tin minerals down to approx. 38 microns.. Pictured below is a pilot plant, designed and built …

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 recovery of …

Operations that want to increase their recovery of metals like tin and tungsten will need to do so at a microscopic level. With the addition of a Falcon Gravity Concentrator, economic particle recovery is possible from minerals that would otherwise be rejected. Both tin and tungsten can be recovered down to a minuscule 3 microns in size.
