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 ...

Flotation separation of Na-feldspar from K-feldspar by ...

2001-7-1  A major proportion of feldspar ores contain both Na-feldspar (Albite) and K-feldspar (microcline or orthoclase) in the same matrix, usually in quantities of about 3–5% Na 2 O and K 2 O. Despite their identical crystal structures and physicochemical properties, flotation appears to be the only plausible method of separating these minerals.
