Beryl Ore

18 · A transparent, beryllium-containing, naturally occurring mineral that forms distinctive hexagonal crystals in a variety of colors due to different impurities that emits toxic fumes of beryllium oxides upon heating and is colorless in its pure form. Beryl ore is found in deeply buried rocks mainly in pegmatites. This mineral is primarily used to produce beryllium metal and beryllium compounds ...

Beryllium

15 · Beryllium is a chemical element with the symbol Be and atomic number 4. It is a relatively rare element in the universe, usually occurring as a product of the spallation of larger atomic nuclei that have collided with cosmic rays. Within the cores of stars, beryllium is depleted as it is fused into heavier elements. It is a divalent element ...

Beryllium Extraction Kinetics on Low Grade Ore

8 · Table of ContentsOreApparatus and ProcedureEffect of H2SO4 Concentration 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).

Sources of Beryllium Metal and Extraction Locations

Today, the extraction of beryllium begins with the mining of raw materials (bertrandite ore and/or beryl ore). Beryl ore is melted in industrial furnaces, solidified and crushed, then treated with sulfuric acid to produce a water-soluble sulfate. Bertrandite ore is crushed, made into slurry and treated with sulfuric acid to form a sulfate.

Extraction of beryllium from Indian beryl by …

A new technique of decomposing beryl ore at low temperature with ammonium hydrofluoride (NH 4 HF 2) is proposed.Removing the fluorides of silicon and aluminium from the reaction product as volatile and insoluble compounds, respectively, have been investigated experimentally and the feasibility of the process has been established to extract beryllium fluoride (BeF 2) as a soluble compound.

Selective extraction of uranium from …

When uranium and beryllium in the ore were leached simultaneously, a complicated downstream separation process was needed. Based on the different chemical stabilities of uranium and beryllium, an acid leaching method was employed in this work to selectively extract uranium from uranium–beryllium ore.
