Beryllium metallurgy is a metallurgical technology for extracting beryllium from beryllium-bearing ore. Beryllium oxides were discovered in 1798 by N. -L. Vauquelin, a Frenchman.
Beryl Ore. In contrast to bertrandite, beryl ore contains beryllium in a tightly bound crystalline structure. Therefore, in order to effectively l each the beryllium with sulfuric acid, it is first necessary to destroy the crystalline structure. The Kjellgren-Sawyer process is used commercially for the extraction of beryllium from beryl. In this
When uranium and beryllium in the ore were leached simultaneously, a complicated downstream separation process was needed. Based on the different chemi-cal stabilities of uranium and beryllium, an acid leaching method was employed in this work to selectively extract uranium from uranium–beryllium ore.
This shows that the extraction of total Be2+ and Al3+ increases with increasing pH from 1 to 6. The beryllium extraction increased from 51.03to 91.68% as the pH of the leachate was adjusted to pH 3 and decreases moderately afterwards. At pH values 4, 5 and 6, 89.54, 88.48 and 88.39% beryllium extraction were obtained, respectively.
Beryllium is a lightweight metal that occurs naturally in rocks, coal, soil, and volcanic dust. Commercially, bertrandite and beryl ore are mined for the recovery of beryllium. Because beryllium is the lightest non-reactive metal and is very rigid, it has many uses in the electronics, aerospace, and defense industries. Beryllium is released into the …
The extraction of beryllium from beryl ore is a cumbersome process because beryl ore is very inert in the sense that no mineral acids under the normal conditions of temperature and pressure attack it (except HF). The extraction process is further complicated due to the requirement of eliminating silica from the reaction products.
