Question

Beryl is an important ore of :
A. $Be$
B. $Ba$
C. $Mg$
D. $Sr$

Answer 1

Hint: In metallurgy we have studied about some very important ores .We now that ore is made up of one or more valuable minerals deposited in the earth crust. The definition of ore is , ‘’The substance which is found in earth crust and a great source of economically useful minerals are called ores. This extraction should be economically beneficial.’’

Complete step by step solution:
Beryl is an important ore of beryllium ($Be$). $Be$ is commonly extracted from beryl ore which can be done by sintering using an extraction. The process of sintering involves mixing beryl with sodium fluorosilicate and soda at temperature about ${770^o}$ C so that sodium fluoroberyllate, silicon dioxide and aluminium oxide can be formed. Then beryllium hydroxide is precipitated from the solution in the water. Then the extraction of beryllium is done by a melt method which involves mixing grinding of ore into powder and heating it then quickly cooled with water.

Additional information:
Beryllium has atomic mass 4and found in group 2 of alkaline earth metal in periodic table. Its electronegativity is 1.57. It is a very rare element found in the universe It has white gray metallic appearance.

Note: The crystal structure of beryllium is hexagonal close packed (hcp). It is used in aerospace material for aircraft components, spacecraft and high speed jets. Beryllium can be extracted from beryl ore by flowsheet flotation method also which offers the best extraction of beryl ore. We can remember that beryl is the ore of beryllium as its name is beryl ore which clearly indicates beryllium.
