| 摘要 | Mineral concentrates are obtained from aluminosilicate and alkali and alkaline earth metal aluminosilicate, phosphate and fluoride ores in a beneficiation process in which the ore is conditioned prior to flotation with a C20 to C22 saturated or unsaturated fatty acid or a mixture of C20 to C22 saturated or unsaturated fatty acids and C18 or lower fatty acids. | ||||||
| 权利要求 | 1. IN A BENEFICIATION PROCESS INCLUDING FROTH FLOTATION OF GROUND LITHIUM ALUMINOSILICATE ORES TO PROVIDE A LITHIUM ALUMINOSILICATE MINERAL CONCENTRATE, THE IMPROVEMENT CONSISTING ESSENTIALLY OF CONDITIONING SAID ORE PRIOR TO FLOTATION WITH FROM ABOUT 0.25 TO ABOUT 4 LBS. PER TON OF ORE BASED ON THE ORE BEING TREATED, OF A COLLECTING AID CONSISTING ESSENTIALLY OF A MEMBER SELECTED FROM THE GROUP CONSISTING OF A FATTY ACID CONTAINING 20 TO 22 CARBON ATOMS AND A MIXTURE OF FATTY ACIDS CONTAINING FROM ABOUT 15 TO ABOUT 75% OF A FATTY ACID CONTAINING 20 TO 22 CARBON ATOMS, BALANCE C18 OR LOWER FATTY ACIDS, SAID PERCENTAGE BEING BY WEIGHT, BASED ON THE WEIGHT OF THE FATTY ACID MIXTURE. 2. The process of claim 1 wherein said collecting aid is a fatty acid containing 20 to 22 carbon atoms, said fatty acid being a member of the group consisting of saturated fatty acids, unsaturated fatty acids or mixtures of saturated and unsaturated fatty acids in any proportion. 3. The process of claim 1 wherein said fatty acid is erucic acid. 4. The process of claim 1 wherein said collecting aid is a mixture of fatty acids containing from about 15% to about 75% of a fatty acid containing 20 to 22 carbon atoms, balance C18 or lower fatty acids, said percentages being by weight based on the weight of the fatty acid mixture. |
