ABSTRACT:
In a hydrometallurgical process of treating zinc-laden dust issuing from electric steel plant furnaces the zinc-laden dust is subjected to a basic leaching or lixiviation in two steps. The dust is subjected to a first leaching of the zinc oxide with a relatively low concentration of caustic soda, then to a second leaching of the zinc ferrite with a higher concentration of caustic soda, then the zinc is extracted from the solution obtained by this basic leaching.
