  • Patent number: 5993758
    Abstract: A process for the simultaneous recovery of substantially pure alumina and silica from an aluminosilicate. The process comprises the following steps: (i) heating the aluminosilicate with hydrated CaCl.sub.2 to obtain calcium-alumino-silicate and calcium-aluminate products, wherein the CaCl.sub.2 is substantially free of MgCl.sub.2 ; (ii) leaching the products with HCl to form a solution comprising AlCl.sub.3 and CaCl.sub.2, and insoluble silica; (iii) separating the insoluble silica from the solution; and (iv) crystallizing AlCl.sub.3 from the solution and recovering the alumina from the crystallized AlCl.sub.3. The process may further comprise the following steps: (v) substantially removing MgCl.sub.2 from the CaCl.sub.2 solution of step (iv); and (vi) recycling the CaCl.sub.2 solution for use in step (i).

  • Patent number: 5009791
    Abstract: A method of magnetically treating drinking water for domestic livestock comprises the steps of: mechanically filtering the water to effect removal of ferromagnetic particles; causing the water to pass through a magnetic field of alternating polarity of an intensity between 600 and 6500 gauses and of a field gradient of between 0.2 and 6.0 kgauss/cm, whereby the flow is laminar at a velocity of between 0.5 and 2.4 m/s.; recirculating water not consumed by the animals by pumping it again through the magnetic field, while choosing the distance between the points of alternating polarity and the water velocity in such a manner that each water particle experiences not less than 2 and not more than 60 polarity changes per second.
