The demand for feldspar as a raw material for the ceramic industry is continuously increasing. Magnetic separation and froth flotation testwork was carried out, in order to decrease the iron contamination and increase the feldspar content.
Feldspar beneficiation plant flow chart:
(1)high quality feldspar manufacturing from the pegmatite: hand picking-broken-grinding (or water-powered roller)-grading.
(2) weathered feldspar of granite: crushing, grinding, classification and flotation (except iron, mica)-flotation (quartz, feldspar separation).
(3) fine grain rock of feldspar (generally contained mica, sometimes contain iron) : crushing, grinding, screening and magnetic separation.
(4) Feldspathic sand: Water elution putty-screening (or flotation separation quartz, etc.).

Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
