Silica sand flotation -Sinonine

In silica sand processing and sand washing plant, flotation is an important way to obtain high purity silica sand.Through flotation, not only the residual weak magnetic iron in silica sand can be removed, but also the aluminum oxide, mica and other non-magnetic materials embedded in the silica sand can be removed, thus making the silica sand more pure

US6098810A - Flotation process for separating silica from

A separation process is provided for treating a feed material comprising silica, feldspar, and metal impurities, including at least one of mica, iron impurities, or refractory heavy minerals, to form one or more products for use in making glass. In the process, the feed material is floated in the presence of a depressant to inhibit the flotation of feldspar and thereby form a concentrate
