Zinc recovery from steelmaking wastes

Since the industrial revolution, both the world wide consumption patterns and our living standards have greatly increased. This could never start without coal and iron. Coal was needed as fuel for the steam engines while iron was used for the production of industrial and consumer goods. The discovery of coke, which burns at a higher temperature than coal, was one of the main drivers in the development of the iron industry and those developments have never stopped since. Nowadays, the drawbacks of the industrialisation are more and more noticeable. Raw material stocks are depleting, waste management is increasingly complex and (air­) pollution has become a problem. These problems are the reason that one of the 17 sustainable development goals of the United Nations focuses on ensuring sustainable consumption and production patterns.
