Sumitomo Metal Mining Shisaka Works has been producing zinc and lead oxide calcine from electric furnace dust of steel making process, which is called EAF dust, by using the Waelz kiln method. Since its commencement of operation in 1977, production capacity and product quality have been improved with many developments in process technologies. Recently, some technologies, especially for minimizing chlorine content of by-product called “clinker”, have been investigated in order to meet the needs of steel mills which desire to recycle the clinker as a raw material from the zero emission point of view. Based on the information obtained through the test, several improvements have been carried out and achieved the expected results. Now, Sumitomo Metal Mining Shisaka Works is pushing forward with environmental preservation so as to contribute to the development of resources circulating society.
