    The lowgrade zinc oxide ores used were given by Lanping County of Yunnan Province, China. The main chemical composition of the lowgrade zinc oxide ores obtained by chemical analysis is listed in Table 1. It can be observed that silica (SiO 2) and a high content of alkaline gangues (CaO + MgO) are the main components of the ore.

    Zinc. Zinc is mainly used to galvanise steel or iron – that is, to apply a zinc coating to stop it rusting. Galvanised steel is used in buildings, cars, white goods and electronics. The strength and flexibility of zinc alloys mean they are widely used to create die casts for industrial uses – for example, in the production of car or machine parts.
