A variety of hard-zinc with the amount of about 140 thousand tons per year are produced in China, and there are many methods developed to dispose them. In this paper, hard-zinc produced by the industry is classified and the differences between lead hard-zinc and aluminum hard-zinc are briefly introduced. The technics features of hard-zinc disposal applied in current industry are mainly specified. Finally some disposal methods under research of hard- zinc are summed up and the developing tendency of disposal hard-zinc in future are indicated.
