Hydrometallurgical Treatment of Zinc Waste Dusts
Hydrometallurgical separation processes offer attractive potential for recovery of marketable zinc from industrial wastes. In view of the importance of having a supply of zinc from a diversity of sources to supplement zinc imports, it is useful to assess the applicability of available separation technology. A brief review is presented of applications of several separation processes which have been applied to a variety of zinc waste dusts. In addition the results of bench scale tests are presented for a technically feasible scheme applied to a high zinc content fly ash from a waste to energy power plant which show a potential of providing a marketable zinc recovery product.
