METHOD FOR REPROCESSING OF LEAD CAKES Russian patent published in 2005 - IPC

Abstract RU 2244758 C1

FIELD: non-iron metallurgy, in particular reprocessing of lead cakes from zinc manufacturing.

SUBSTANCE: claimed method includes heat treatment of lead cake with flux followed by smelting wherein before heat treatment mixture of lead cake, calcium hydroxide, and clinker from lead cake milling is balled to produce pellets. Pellets have fineness preferably of 30-100 mm. Method of present invention affords the ability to increase total coefficient of lead recovery by 3.1 %.

EFFECT: decreased energy consumption and reduced dust content in exhaust gas.
