Silica and Iron Recovery from a Residue of Iron Ore

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%).

5 Factors Affecting Silica Sand Flotation - Mining-pedia

2020-11-23  Flotation is one of the commonly used methods for silica sand beneficiation. It is mainly used to remove mica and feldspar minerals that are symbiotic with silica sand. However, in the actual production process, the flotation process will be affected by many factors, including: feed size, slurry temperature, slurry liquid chemical composition, flotation reagents and other flotation conditions.
