Abstract

Beryllium values are recovered from beryllium ores by treating the fused and quenched or the sintered ore with sulphuric acid and simultaneously or subsequently leaching the sulphated ore with a mixture of ethanol and water containing 70 to 95% by weight of ethanol. An excess of sulphuric acid e.g. 33% by weight, is used above that necessary to convert to their sulphates all the metal oxides contained in the beryl. The leaching may be effected either by heating the sulphated material under reflux with an 85% ethanol water mixture or by grinding the sulphated material in a ball mill at ambient temperature, with a 75% ethanol water mixture. Ratios of leach liquid to ore are given as 200 mls. ethanol/water to 5 gms. ore, 100 mls. ethanol/water to 5 gms. ore, or 50 mls. ethanol/water mixture to 5 gms. ore according as to whether the ore is leached by reflux, by ball milling, or simultaneously with the sulphation. The sulphated ore is heated prior to leaching to render the silica content insoluble, or when simultaneous leaching is employed, the leach liquid is evaporated the residue heated to render the silica insoluble and the beryllium values extracted with water. The residual ore after leaching may be subjected to a further leaching with an ethanol/water mixture, and the acidity of this mixture may be adjusted to a pH of 2 by the addition of sulphuric acid.
