The separation of beryllium from iron, aluminium and …

The separation of Ti(IV) and Cu(II) from beryllium is not satisfactory and requires rather large columns. Bi(III), Pb(II), Hg(II) and the alkali metals are eluted together with beryllium, but can be separated by other methods. Typical elution curves and results for the quantitative separation of binary synthetic mixtures are presented.

Quantitative separation of beryllium from magnesium

A much better separation of copper(II) from beryllium can be obtained by eluting copper(II) with HC1—acetone [17,18] or HBr—acetone [19] mixtures while beryllium is retained. Titanium(IV) can be separated in an additional procedure by elution with 0.5 M sulphuric acid containing 0.15 % hydrogen peroxide while beryllium is retained [20].

Determination of Beryllium by Fluorometric Method

Chemical separation of other ions is usually unnecessary. The method gave reliable beryllium determinations on samples in the 0.01- to 0.37-percent BeO range. The method is particularly applicable to low-grade beryllium ores; however, semiquantitative beryllium determinations have been made on beryl containing 12.0 …

Review on the Beneficiation of Li, Be, Ta, Nb-Bearing

Sometimes, when the separation methods such as manual or color sorting, gravity separation, magnetic separation, or flotation cannot fully meet the mineral separation requirements, the leaching method is used instead [89,90,91]. For example, in LPPO, it is difficult to obtain a high-grade beryllium concentrate by flotation when the …
