The production of beryllium oxide from beryl ore is described. The acid‐resistant crystalline beryl ore is converted to a reactive form by melting the ore in an electric furnace and quenching the melt. The reactive material is treated with sulfuric acid and beryllium sulfate is produced by a crystallization process. The beryllium sulfate is converted to beryllium oxide by heating. The production of beryllium‐copper in an electric arc furnace by direct reduction of beryllium oxide with carbon in presence of copper is described. Data are given on laboratory results and on production on an industrial scale.
