摘要： A process is disclosed for producing tungstosilicic acid which involves adding sodium silicate to a first solution of sodium tungstate while assuring that the pH of the resulting mixture is from about 2 to about 6, the pH adjustments being made with a cation exchange resin on the hydrogen cycle, to produce a second solution. The solids are removed from the second solution which is digested at a temperature of greater than about 50.degree. C. and then contacted with a cation exchange resin on the hydrogen cycle to produce a third solution which is essentially a tungstosilicic acid solution containing at least about 99% by weight of the starting tungsten as tungstosilicic acid.

摘要： A process is disclosed for producing ammonium tetrathiomolybdate. The process involves reacting an ammoniacal molybdate solution with hydrogen sulfide gas, the solution and the gas being in a closed system and the flow of the gas being regulated at an elevated pressure to form a slurry consisting essentially of a solid essentially all of which is ammonium tetrathiomolybdate containing a portion of the starting molybdenum and a mother liquor containing the balance of the molybdenum. The slurry is then cooled to ambient temperature and the solid is removed from the major portion of the mother liquor. The solid is then washed with water and with alcohol followed by removal of the resulting respective water and alcohol washes to remove the remaining portion of the mother liquor and soluble impurities from the solid. The resulting washed solid is then dried at ambient temperature to form the final ammonium tetrathiomolybdate.

摘要： A process is disclosed for recovering tungsten and rhenium from a relatively impure tungsten and rhenium solution. The process involves adjusting the pH of the solution to from about 9.0 to about 10.0 to precipitate impurities, and removing the impurities. The purified solution is adjusted to a pH of from about 0.5 to about 7.0 with a mineral acid. To the purified solution is added a solution containing sufficient hexamine to subsequently form a first hexamine tungsten solid containing the major portion of the tungsten. The hexamine solution is at essentially at the same pH as that of the pH adjusted purified solution. The resulting hexamine-tungsten-rhenium mixture is agitated at a sufficiently low temperature for a sufficient time to form the first solid and a first mother liquor containing the major portion of the rhenium. The first solid is separated from the first mother liquor.A process is disclosed for accomplishing the above in which a relatively impure tungsten and rhenium solution is purified as above. A hexamine solution which is not pH adjusted is added to the purified solution followed by adjustment of the pH of the resulting hexamine-tungsten-rhenium mixture to about 0.5 to about 7.0 as described above to form a first solid containing the major portion of the tungsten and a first mother liquor containing the major portion of the rhenium, followed by removal of the first solid from the first mother liquor.
