The froth flotation process 30, although shown as a single stage, may involve a number of successive flotations, as is well known. Thus, in the case of feldspar ore or spodumene ore, in a final flotation step, feldspar particles are floated as part of the froth 32, while silica particles settle as tails 34, both of which are recovered as products.
Nov 23, 2020 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.
