Research of Recovering Zinc from Hot-dip Galvanizing Slag

摘要

According to the theoretical analyzing of vacuum purification of hot-dip galvanizing slag, a double-vacuum purification method and correlative equipment is introduced. This technology is explored independently by Baosteel. It is designed for zinc recycling in the field of zinc smelting plant. The new method may provide a way of less investment, less energy cost and clean production environment in zinc slag utilizing.
