May 22, 2016 Sink and Float separation process. One of the first commercial applications of a medium to effect a sink-float separation used a fine silica sand suspension for treating anthracite coal and is known as the “Chance” process. The method used for cleaning the medium is decantation which limits the minimum grain size of the solid in the suspension.

Ferric oxides are separated from silicates by flotation or magnetic separation. The residue generated by magnetic separation consists of fine iron oxide and silicates. Two types of residues are generated by flotation. One of them is similar to sand and consists of quartz particles (greater than 85 wt%) and iron oxides (less than 15 wt%).
