    A Computational Fluid Dynamic Modeling Study of Slag

    Zinc slag fuming is a reductive treatment to recover zinc from zinc containing slag. The earliest experimental work on zinc fuming was conducted in Australia by Sulphide Corporation at Cockle Creek between 1906 and 1920 [2]. The process has become operative since 1930's to recover zinc from lead blast furnace slag....

    RESIDUE TREATMENT PRACTICE library.aimehq

    Slag fuming is carried out on a 55 metric ton batch process in completely water-jacketed furnaces where the slag is blown with a mixture of powdered coal and air. The coal-to-air ratio is controlled to maintain strongly reducing conditions, thus, fuming the metals from the slag. The metal vapours are subsequently re-oxidized with air above ...
