“…In order to extract beryllium from low-grade minerals like bertrandite, the Materion Corporation in the U.S.A. has employed sulfate leaching combined with solvent extraction, using a mixture of D2EHPA, ethanol, and kerosene as the extractant to concentrate beryllium. Organic solvents such as CYANEX 921, CYANEX 272, and tributyl phosphate have also been reported for beryllium extraction from aqueous solutions. ,, However, the use of traditional organic solvents causes serious environmental challenges. Noxious volatile organic compounds (VOCs), which are produced by some molecular diluents traditionally used in liquid–liquid extraction, have been rigorously controlled .…”

Beryllium is a very important strategic metal and has been applied in high-tech industries. Since the low beryllium content in minerals, the enrichment technique is a vital aspect of beryllium smelting. In this study, we present a novel protic ionic liquid, 4-Hydroxymethyl-5-methylimidazolium p-Chlorobenzoate ([Hymim][pCb]), as an efficient and environmentally friendly extraction solvent for beryllium preconcentration in aqueous solution. Our research demonstrates that Be II can be captured rapidly with high efficiency, reaching nearly 99.6% within 2 h. By controlling the initial metal concentration and pH condition, we could achieve the selective extraction of beryllium in the presence of other heavy metal ions. Our findings also shed new light on the extraction mechanism established by the material characterizations and density functional theory (DFT) calculation, revealing that metal ions disrupt the proton transfer between the cation and anion in the ionic liquid, leading to metal chelation with the cation and subsequent translation of the anion into an aqueous solution. Overall, our research presents a novel method for the enrichment of beryllium in the smelting process while also expanding the scope of protic ionic liquid applications. The efficient and selective extraction of beryllium demonstrated in this study holds great promise for the advancement of beryllium-related industries.

Processing of the beryl from received geological sample collected from Eastern Desert of Egypt has been studied via acidic fusion process using K 2 SO 4 under different factors. The recovery of beryllium from the prepared sulfate solution has been accomplished by solvent extraction namely; TOA. The optimum conditions for sulfate fusion for almost complete breakdown of beryllium guarantee 1/3 ore/salt ratio at 550°C for 3.5 h. The relevant conditions for the extraction and stripping of beryllium by trioctyl amine determined. The studied optimum extraction conditions involved 8 × 10 -3M TOA concentration, 1/1 O/A ratio at a pH of 0.8 and 15 min. Beryllium was stripped by 1.5M H 2 SO 4 solution in 1/1 O/A ratio for 20 min. From the corresponding McCabe-Thiele diagrams, it was noticed that 3 theoretical stages for each of the extraction and stripping separately were required. From the stripped solution, beryllium was precipitated as beryllium hydroxide at pH 9 using 10% NaOH solution. The produced beryllium hydroxide has then been properly dried at 150 °C for 1 hr and analyzed using AAS.
