What is the Principle of Magnetic Separation?
What is Magnetic Separation? Magnetic separation is a method of using magnets to remove magnetic and ferrous materials from mixtures. Essentially, when a magnetically susceptible material is placed in a magnetic field, magnets can exert magnetic forces on those materials, attracting them closer while non-susceptible materials remain unaffected.

Beryllium Extraction and Beneficiation
Beryllium Processing & Extraction Problem. Beryl, the principal Beryllium mineral, is found generally in pegmatites associated with mica, feldspar, and quartz. Its specific gravity is almost identical to quartz and feldspar, thus ruling out the possibility of gravity separation methods. Beryl is harder than quartz.
