Beryllium Extraction Kinetics on Low Grade Ore

Beryllium is recovered from the fluoride leach liquor by precipitating it as beryllium hydroxide with caustic soda. In the sulfate process, beryl ore is melted (with or without fluxes such as CaCO3 or Na2CO3) in an electric furnace at about 1625C and quenched in cold water to obtain a glass. Get price

NDLI: IMPROVEMENTS IN OR RELATING TO EXTRACTION

A process for extracting Be from beryl ore is outlined in which only a minor proportion of the Al in the ore is also extracted. The process comprises leaching the ore with an aqueous solution containing 0.2 to 5 N H/sub 2/SO/sub 4/ and 0.1 to 0.5 N HF at a temperature between 200 deg C and the critical temperature of the leaching solution, preferably at least 300 deg C.
