Document Type and Number:
Japanese Patent JPS627254
Kind Code:
B2
Abstract:
Zinc and lead are separated together out of dust derived from a gas-cleaning installation in iron or steel making by a flotation-separation treatment. In order economically to provide a good separation of these metals and to leave a residue which is re-usable in an ore-preparation process in the iron and steel industry, the flotation-separation treatment is at a pH of 7 to 9 and is effective to achieve a separation, according to size of the dust particles, of a floated component in which the zinc and lead are concentrated and a non-floated component which is suitable for re-use.
