Using Gravity Concentration to Recover Tin and Tungsten. 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.


Most gold ores should be milled to at least 50–80% passing 75 µm for effective gold exposure (Marsden and House, 1992). Therefore, at least 10 kg of each representative composite sample is milled to 50% passing 75 µm for the initial testwork (grading, heavy liquid separation and/or gravity separation). A split aliquot of 1 kg is milled to
