Abstract
1392523 Production of high purity ferrous sulphate solutions P J McGAULEY and A A DOR 23 Feb 1972 [13 April 1971] 44219/74 Divided out of 1392521 Heading C1A High purity solutions of ferrous sulphate are produced from waste solutions containing ferrous sulphate, sulphuric acid and metallic impurities by (a) heating and reacting the solutions at a temperature above 65 C. with acid-soluble iron sulphide in quantities that exceed the acid content of the solution on a stoichiometric basis to neutralize the acid, to generate ferrous sulphate and H 2 S gas, and to purify the solution by reactions of the H 2 S with the soluble impurities to precipitate the undesirable metals from the solution, (b) evaporating water to produce a purified solution that is substantially saturated with ferrous sulphate and is at a temperature of 50-80 C., (c) separating the solids from the solution and accumulating both as products of the process. It is preferred to carry out this process in conjunction with the co-current or current-current leaching processes described in the parent Specification 1,392,521.
