Abstract
The soft iron ores of the north of Cuba and similar ores containing oxides or oxides and silicates of iron and aluminium and small quantities of nickel, manganese, and chromium, are dried and preheated and then roasted in contact with sulphur dioxide under sulphatizing conditions and then leached with water to obtain a solution of the sulphates of the aluminium and other metals, leaving a residue consisting of a purified iron ore. The sulphate solution is preferably reduced, for instance by iron or sulphur dioxide, to minimize the quantity of iron that will accompany the aluminium in the subsequent precipitation, and is treated with calcium chloride to convert the sulphates into chlorides, and the precipitated calcium sulphate is separated. The chloride solution is treated with the requisite quantity of calcium carbonate or the like to precipitate as hydrates the aluminium, ferric iron, and chromium. The precipitate is separated and treated for the recovery of alumina by Bayer’s process, the residue being treated for the recovery of the chromium or it may be «sintered with the ore.» The solution is then treated with air and calcium carbonate to oxidize the remaining iron and precipitate it as ferric hydrate, only the necessary quantity of calcium carbonate being employed. The filtrate is treated with lime to precipitate nickel and manganese hydrates. The precipitate is washed and dissolved in sulphuric acid, the solution being then electrolyzed with an insoluble anode and a nickel cathode so as to obtain metallic nickel and manganese dioxide. Each electrode may be enclosed in a diaphragm, for instance a canvas bag, the mixed hydrates being introduced into the bath outside the diaphragms, or into a separate vessel between which and the electrolytic cell the solution circulates. The Specification as open to inspection under Sect. 91 (3) (a) states that a solution containing iron and nickel, with or without other metals, may be treated with lime or other reagent to precipitate all the metals as hydrates, the precipitate being smelted to obtain an iron-nickel alloy, any manganese present being slagged off if desired. Any desired proportion of the iron could be precipitated as above described, and removed before the precipitation of the mixed hydrates. This subject-matter does not appear in the Specification as accepted.
