Feldspar Beneficiation & Flotation Process. Beneficiation by Flotation of feldspar is well established. It is a simple matter by flotation to remove the contaminating impurities and keep the alumina (Al2O3) content at 19% even on low grade feldspar ores. Dry recovery methods are economically limited to about 17% Al2O3.

Feldspar occurs mostly as white, green or red-brown, ranging from flesh colour to the colour of brick. A special type of feldspar is extracted from pegmatites in very small quantities (50-100 t per year) at a mine near Buckingham, Québec. This feldspar has a glassy lustre, is high in potassium oxide (K 2 O), and low in sodium oxide (Na 2 O ...
Notes. Theoretically speaking, the term 'feldspar' refers to a family of minerals with a specific crystalline presence. However actual feldspar powders are made from crushed crystalline rock containing a mixture of aluminum silicates of sodium and potassium (with minor amounts of lithium or calcium). They normally contain 10-15% alkali (K 2 O, Na 2 …

In the present study, effects of several operating parameters on the separation efficiency of mica from feldspar by spiral concentrator were investigated. For this purpose, an albite ore containing mica was treated in a full scale Reichert spiral (model HG7) under various test conditions. During the study, particle size distribution, solid ...
Feldspar. Feldspar (silicate, chemical formula Na (AlSi 3 O 8 ), where Na can also be replaced by K) is one of the main constituents of the Earth's crust. Feldspar can be characterised by: High inertness in various media. Low fine crystalline silica fraction (no labelling) (Unispar PG (W)) Whiteness (Unispar PG W).
