Beryllium concentrating mill

Beryllium Extraction and Beneficiation

In general, beryl will concentrate with the feldspar flotation product. Depressing the feldspar and reflotation of the beryl into a high grade marketable concentrate (at least 8.0% BeO) is the usual procedure. GRINDING AND CLASSIFICATION For the grinding of beryl and other non-metallic ores a Rod Mill is used to minimize sliming.

Beryllium Copper

Beryllium Copper Overview. Copper beryllium alloys are used for their high strength and good electrical and thermal conductivities. There are two groups of copper beryllium alloys, high strength alloys and high conductivity alloys. The wrought high strength alloys contain 1.6 to 2.0% beryllium and approximately 0.3% cobalt.
