Title: Improvements relating to the hydrometallurgy of nickel and cobalt
IPC: C01G51/00
Filed: 1952-09-09
Abstract: A nickel-free cobalt product is separated from a solution comprising nickel and cobalt salts by adjusting the salt-forming anion ratio of the solution to provide at least three chemical equivalents of said anion to each mol. cobalt, and at least two of each mol. nickel, saturating the solution with ammonia, and oxidizing at a temperature of at least 150 DEG F., up to 450 DEG F., and pressure at least equivalent to the vapour pressure of the solution with a substantially sulphur-free oxidizing gas, e.g. oxygen and/or air. Where sulphate solutions are treated, the adjustment of the sulphate content may be effected by adding ammonium sulphate.  The cobalt precipitate corresponds approximately to [CO(NH3)6](SO4)32H2O and contains up to say 85 per cent. of the cobalt originally in solution. After removal of the precipitate, the nickel solution may be again treated with ammonia and if desired with oxygen to remove the remainder of the cobalt.  The second precipitate may contain nickel and is either returned to the initial oxidation step, or used for the recovery of a mixed metal product.  Ammonia may be further added after the initial oxidation.

Title: Improvements in and relating to a method of treating products by oscillating high-frequency electrical currents producing alterations of the products
IPC: A23L3/01
Filed: 1946-08-09
Abstract: Processes of a physical, chemical or biological nature are furthered by the passage of an intermittent oscillating high-frequency current through the mixture, gas, liquid or tissue to be influenced.  The ratio of pulse time to the interval between pulses is so chosen that the heat developed during the pulse time is led away in the course of the whole period and so is unable to produce secondary processes to a detrimental extent.  The method is applicable, for example, to the production of ozone, nitric p  oxide, acetylene, sulphur dioxide, and in polymerization and sterilization, and in the checking of cell growth.
