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.

Beryllium (Be), a lightweight metal with significant industrial applications, poses notable environmental and health risks due to its toxicity and persistence, and widespread use, particularly in the mechanical, aerospace, and electronics sectors. It is commonly alloyed with other heavy metals to enhance material properties. The primary environmental pathways for Be release include emissions from coal and fossil fuels combustion, as well as the incineration of solid wastes. Once introduced into the natural environment, primarily Be associated with soil particles and sediments, particularly in terrestrial and aquatic ecosystems. This review examined the pathways through which Be enters the environment, including atmospheric deposition, industrial discharge, and leaching from natural geologic deposits. The paper highlights the bioavailability and mobility of Be in soil and water systems, emphasizing the geochemical and physical factors influencing its persistence and potential for bioaccumulation. Risk appraisal methodologies are evaluated, with a focus on human exposure routes, including inhalation of airborne particulates and ingestion of contaminated water and food. The toxicological impacts on human health are critically analyzed, detailing both acute and chronic effects, such as respiratory diseases and carcinogenicity. This review evaluates existing regulatory frameworks and remediation strategies, assessing their efficacy in mitigating environmental contamination and exposure to Be. By integrating interdisciplinary research, this paper provides an in‐depth understanding of the environmental behavior and toxicology of beryllium, offering insights that can inform robust policy frameworks and shape future research directions.
