Beryllium - University of Denver

The processing of beryl to produce beryllium metal or the oxide is one of the most difficult tasks in extractive hydrometallurgy. This difficulty arises from the fact that the beryl ore is refractory to almost all chemical leachants including boiling sulfuric acid (Schwenzfeier, Jr., 1955; Engle and Hopkins, 1924).

Beryl: Mineral information, data and localities.

The metal beryllium is mined by its extraction from the beryl ores. It does not occur free in nature. A relatively abundant metallic element in the Earth's crust, beryllium, has not been widely used due to the high cost of production and its limited consumption. The beryl ore seems to have more content of beryllium compared to the bertrandite ore because of which it becomes an extremely ...
