Abstract
1,218,762. Treating flue dust. L. A. DUVAL. 2 Feb., 1968, No. 5377/68. Heading C1A. Flue dust which comprises zinc oxide and at least 50% by weight iron oxide is treated at 150-250 F. with spent pickle liquor derived from hydrochloric or sulphuric acid to at least partially leach the zinc oxide from the dust, the leached dust then being separated from the zinc salt solution. The flue dust may be from a basic steel-producing process, and a pH of 1-5À5 is preferably maintained in the process. Water may be evaporated from the zinc sulphate or chloride solution to concentrate or reduce to dryness the salt. This concentrated zinc salt solution or solid salt may be roasted at about 270 F. to convert any ion salts remaining to iron oxide whilst leaving the zinc salt unchanged, the HCl or SO 3 given off being absorbed in water to form acid. The product of roasting may be washed with water and the iron oxide filtered off, the zinc salt then being stored after concentrating or reducing to dryness.
