Abstract
100,488. Hovland, H. B., (Assignee of Frankforter, G. B.). May 15, 1915, [Convention date]. Copper sulphate; sulphates in general. - Metallic ores &c. are sulphatized by treating with an oxidizing-agent without the addition of an acid or ferrous solvent or of a ferric salt in presence of available sulphur under pressure and at a suitable temperature. When the ore &c. does not contain sulphur, sulphurous acid or metallurgicalfurnace fumes and air or oxygen or a solid oxidizing-agent such as manganese dioxide may be used; but when the ore, to which a source of sulphur such as pyrites may be added, contains sufficient sulphur, air or oxygen alone may be used. Heating and cooling devices may be provided in the pressure vessel. The particular application described is the treatment of copper ores, the conditions suitable for a dry process mentioned being a temperature of 500‹ C. and a pressure of 50--100 lb. per sq. in.; but the pressure may at intervals be reduced to or below atmospheric, for instance to facilitate the decomposition of ferric sulphate. The reaction vessel has a double wall, the space between being filled with an inert gas, such as nitrogen, at a pressure greater than that employed inside, for instance 150 lb. per sq. in. It is stated that the ores may be treated by a wet process, oxidized copper ores being treated under sufficient pressure at ordinary temperature. The Specification as open to inspection under Sect. 91 (3) (a) does not exclude the addition of an acid or ferric solvent or a ferric salt and states that catalysts such as nitrogen oxides, metallic chlorides, or water may be employed to facilitate the oxidation nf the sulphurous acid; that an electric arc may be used for the heating and may produce the nitrogen oxides in situ; and that the process may be applied to the sulphonation of bodies such as aromatic hydrocarbons in the manufacture of phenols, naphthols, &c. and the preparation of ether from alcohol. This subjectmatter does not appear in the Specification as accepted.
