Abstract：The utilization status of zinc resources containing zinc silicate at home and abroad were summarized from its physical and chemical characters. The two main problems in the traditionally pyrometallurgy process are low reduction efficiency and high energy consumption. In the processes of extracting zinc from the zinc resources containing zinc silicate by strong acid or strong alkaline，a large number of impurities in the zinc resources are also dissolved in the solution，which is great harmful for purifying of solution and zinc extracting. Compared with the strong acid and strong alkaline leaching processes，the impurities in zinc resources are rarely leached by ammonia in the ammonia leaching process. Based on the leaching differences between the zinc oxide and other impurities in the ammonia leaching process，the roasting followed by ammonia leaching zinc was proposed in this paper in order to improve the utilization of zinc in zinc resources. In the process，the zinc silicate mineral was transformed into zinc oxide，and then the zinc oxide was leaching by ammonia. Finally，the main necessary works should be done in this process were proposed and analyzed.
