Then I took the vise and put a bag under it. Then I put the two pieces in the jaw and crushed them, it took 5 run before a good part of the ore was crushed to frit. 14 g of frit was obtained and 6.6 g pieces. About 0.9 g was lost during crushing. The frit was mixed with equivalent weight of calcium carbonate.

Beryllium. Beryllium (Be) is a silver-white and very light metal. It has a very high melting point at 2349 °F (1287 °C). It is found in nature primarily as bertrandite, which is mined in Utah, or as beryl. The combination of its light weight and high melting point makes it valuable for making metal alloys which are used in electronic and ...
particle size reduction of ore is known as comminution which is accomplished by crushing and grinding. Com-minution is followed by concentration to increase the metal percentage in the ore by removal of gangue minerals. Min-eral concentration is achieved by different methods such as gravity separation, magnetic separation, froth flotation, etc.
