Recycling. Zinc Smelting and its Recycling.

Abstract

Zinc is one of the most important metal element for our living. It is no doubt that recycling is the most important issue for industry. Secondary zinc industry has been established based on economical situation. But still important problems on zinc recycling have been remained. In this report the outline of zinc recycling is discussed. The most important issue on zinc recycling is treatment of EAF dust from steel recycling system and fly ash of incineration process. Both materials include certain amount of halogen elements. They cause several problems on their treatment process. It would be emphasized that combination of steel making process and non-ferrous metal smelting process could give the solution not only on future zinc recycling but on the waste management in Japan.
