Abstract

Oxidized ores &c. are treated for the separation or concentration of the metallic values, other than iron and aluminium, by submitting the ore to the action of a free halogen, with or without the addition of a gaseous halogen acid, in the absence of any carbon or sulphur-bearing reducing-agent, at such a temperature as to convert some of the constituents of the ore into volatile halogen derivatives. The conditions may be adjusted so as to obtain selective distillation of the halogen derivatives; or two or more derivatives may be volatilized and collected together, or separately collected by fractional condensation or by absorption in a solvent for one or more of the constituents. The treatment of the following ores is described:- cobalt ore containing arsenic, iron, manganese and nickel; calamine; pyrolusite; malachite; lead chromate; chromite; wolframite. Various chlorides, and also tungsten and chromium oxides, are obtained. According to one of the Provisional Specifications, the process is carried out in a reducing-atmosphere; and according to both Provisional Specifications, hydrochloric acid gas may in some cases be used without chlorine. Specifications 159,071, 176,428, and 176,729 are referred to.
