Recovery of Metallic Zinc from Blowings and Utilisation of Zinc Skimmings

Abstract

The galvanizing industry is the major consumer of virgin zinc produced in the world and nearly half of the primary zinc is consumed for galvanizing alone. Till recently the entire zinc demand of the country was met solely by imports involving a huge drain of foreign exchange. About 40,000 to 50,000 tonnes of virgin zinc is consumed every year in the country by the galvanizing industry alone. The anticipated future demand for zinc the country is comparatively high in relation to the expected production that may be achieved by the zinc smelters under installation.
