Abstract
In a process for up-grading iron ore, it is crushed and added to aqueous hydrochloric acid to form an acidic solution of ferrous chloride that also contains aluminium and/or phosphorus, with or without calcium, the pH of the solution is raised so that the aluminium and/or phosphorus are precipitated as hydroxide or phosphate without precipitating ferrous iron, the solution is separated from insoluble matter and the ferrous chloride is converted to ferrous or ferric oxide. When the iron in the ore is in the ferric form, a solution of ferric chloride is obtained and reduced to ferrous chloride by reaction with metallic iron. Silica and alumina may be filtered from the solution with the precipitate or before the aluminium and/or phosphorus are precipitated. The pH is raised to between 3 and 5 by adding calcium carbonate or ferrous carbonate to obtain a pH of about 1,5 in a first stage, and than by adding metallic iron to reduce any ferric chloride to ferrous chloride and to react with remaining free acid. Soluble calcium is precipitated by adding ferrous sulphate or manganese sulphate. The ferrous chloride is removed as crystals by evaporation or by salting out with gaseous hydrogen chloride, and then is hydrolyzed by heating at 300 DEG to 350 DEG C. in combustion gases containing steam and free oxygen. Salts which are not hydrolyzed may be removed from the iron oxide by leaching with water. An example is given. Specification 734,080 is referred to.
