Abstract
524,321. Beryllium compounds. I.G. FARBENINDUSTRIE AKT.-GES. Jan. 24, 1939, No. 2499. Convention date, April 5, 1938. [Class 1 (iii)] Solutions containing beryllium in the form of fluorine compounds are treated, e.g., at 50‹C., with an alkaline earth (including magnesium) hydroxide, and the beryllium is separated from the mixed precipitate (a) by treatment with a solution of caustic alkali or of an alkali metal or ammonium carbonate, filtering, and boiling the filtrate to precipitate beryllium hydroxide or basic beryllium carbonate, or (b) by calcining the precipitate, e.g., to 500-700‹C. to convert the beryllium hydroxide into oxide and chlorinating at an elevated temperature in the presence of carbon to volatilize beryllium chloride. In examples, the beryllium solutions treated are obtained from the decomposition of beryllium ores with sodium silico-fluoride; calcium hydroxide is added to the solutions and the suspensions treated with carbon dioxide to convert any caustic soda formed into sodium bicarbonate; ammonium carbonate is then added, the solution filtered and the filtrate boiled to precipitate basic beryllium carbonate.
