Abstract
Iron ores or concentrates containing other metals, e.g. nickel, copper, lead cobalt, are heated in a slurry with water at 200-260 DEG C and at a pressure of more than 400 lbs./sq. in., up to 1,000 lbs./sq. in., in the presence of sulphur, which may be present in the ore, and an oxidizing gas, e.g. air or oxygen, until basic iron sulphate is precipitated, which is then separated. The amount of water in the slurry is such that the concentration of the sulphuric acid formed reaches 15-250 grams/litre. After removal of the basic iron sulphate, the acid content is reduced to 15-50 grams/litre by the addition of lime, and the partially neutralized solution again subjected to the high-pressure, hightemperature oxidation step to precipitate substantially all of the remaining iron. Copper, nickel and cobalt sulphates are present in the solution, which may be treated with high pressure hydrogen to precipitate metallic copper, and then crystallized to separate nickel and cobalt sulphates. Lead sulphate is precipitated with the basic iron sulphate.ALSO:Iron ores and ore concentrates containing also nickel, copper, cobalt, lead &c. are treated by a process which produces a solution of nickel, copper and cobalt sulphates, (see Group III), from which metallic copper is precipitated by high-pressure hydrogen.
