Metal plated steel sheet scraps are heated to a temperature in the range of about 200.degree. C.-500.degree. C. so that organic material adhered to the scraps is evaporated and removed. Then, the scraps from which organic material has been removed are heated to a temperature in the range of about 500.degree. C.-950.degree. C. so that the plated metal, for example zinc or aluminum, is evaporated. The evaporated metal flows to a retrieving device where the evaporated metal is condensed and retrieved.
