Abstract

A method for the primary treatment of spent batteries and domestic cells is proposed. Basic processes for the secondary treatment, metals recovering and detoxifying wastes are developed. Iron is directly recovered in the primary treatment as a ferrous scrap. Zinc is recovered from ammoniacal solution obtained in primary treatment by means of a hydrothermal process. For recovering cadmium, copper and nickel, a cementation with zinc dusts is proposed along with the application of the COCADEX process. Detoxifying the fraction bioxide obtained and the mercury recovered are made by heat treatment at 300- 400°C. The heat treatment wastes and the non ferrous fraction can be treated in a Waelz furnace, for the simultaneous recovery of zinc and cadmium contained in the waste as a Waelz oxide.
