Abstract

1,027,394. Beneficiation of beryllium ores. UNITED KINGDOM ATOMIC ENERGY AUTHORITY and COUNCIL FOR SCIENTIFIC & INDUSTRIAL RESEARCH. Feb.12, 1963 [Feb. 15,1962], No. 5945/62. Heading B2H. Beryl concentrate is upgraded by conditioning the pulp with a phosphate solution and re-floating under acid conditions. As shown in the flow diagram aqueous pulp concentrate, assaying 2% beryllium oxide from a previous beneficiation process, is conditioned in a tank 1 with a phosphate solution such as sodium hexameta-phosphate, phosphoric acid or ammonium phosphate. Water is added to give a density of 30% solids. In such condition a cyclone washer is employed to remove slimes smaller than 24 microns from the pulp and a second such wash is considered advisable. The pulp is then frothed in a chamber 5 with the addition of sulphuric acid to give a pH of 4. 5. The railings from chamber 5 are given added water and sulphuric acid and proceed with a pH of 2. 5 to a tank 8 where petroleum sulphonate collector is added at a rate of 2. 5 1bs/ton with a frother such as methyl isobutyl carbinol. A second concentrate is now extracted from a flotation chamber 9 and, together with the concentrate from the earlier flotation chamber 5, passes to a thickener 10. By way of tank 14 the thickened pulp is drained on a drum filter 15 the scrapings from which are dried in a rotary drum 17.
