Zinc is a commonly used nonferrous metal. It is the latest kind of metal being extracted in ancient times among the seven nonferrous metals of copper, tin, lead, gold, silver, mercury, and zinc. The metallic zinc takes on white-bluish color; its hardness is 2.0, melting point 419.5℃, and boiling point 911℃. When it is heated up to 100～150℃, it has good malleable performance, and its specific gravity after rolling is 7.19. Zinc can be made with many kinds of nonferrous metals into alloys, of which the major is brass, which is made up of zinc, copper, tin and lead; and zinc can also be made into die-casting alloy with aluminum, magnesium, and copper. Zinc is mainly used in the fields of steel, metallurgy, machinery, electric, chemical engineering, light industry, military, medicine, etc.. Zinc concentrate is the main materials for producing the metallic zinc, zinc compounds, etc. The metallic zinc is mainly used in the production of copper alloy, lead alloy, magnesium alloy and lead-zinc alloy; and zinc compounds are mainly used in the fields of steel, metallurgy, machinery, electric, chemical engineering, light industry, military, medicine, etc..
The Company has obtained the exploration right for two copper poly-metallic deposits in Huangtupo mine of Hami, with total ore exploration area of 70.24 km2; and the exploitation right for one copper-zinc deposit with a ore exploitation area of 2.021 km2. Presently the proved reserve of copper ore in the mine is 17.5074 million tons (including ore cluster I and ore cluster II), in which, the copper reserve is 183 thousand tons, the zinc reserve is 196.1 thousand tons, and there are other associated metals of gold, silver, cadmium, and gallium, etc., the average ore grade is at a relatively high level.div>
