EXTRACTION OF BERYLLIUM FROM ORES ANACONDA
The extraction and the recovery of beryllium substantially devoid of zinc and other impurities from low and medium grade acid-leachable berllium bearing ores, e.g., bertrandite, is accomplished by acid leaching at a pH below about 2 but above about 1.2, preferably between 1.3 and 1.5, and advantageously with the aid of a soluble fluoride additive to recover the beryllium in solution

the extraction and the recovery of berylium substantially devoid of zinc and other impurites from low and medium grade acid-leachable beryllium bearing ores is accomplished by acid-leaching at a ph in the range from about 1.2 to about 2, preferably between 1.3 and 1.5, and advantageously with the aid of a soluble fluoride additive followed by raising the ph of the leach liquor initially to
Extraction of beryllium from its ore
2021-8-25 2021-8-25 The properties that make beryllium useful also make it difficult to extract from its ores. Robert Maddox, Howard Gimperline, Jack Valliquet, Richard Shank, and other chemical engineers at Brush Wellman’s plant in Elmore, Ohio in the early 1960’s devised a unique solvent extraction process.
