The project was put into production in 2012 based on the process of acidification and roasting. The area of a single fluidizedbed furnace is 119m2 to produce 115kt/a zinc calcine and 200kt/a sulfuric acid, and superheated steam is used for power generation and waste heat utilization. Various indexes have achieved or surpassed domestic leading level the project start up.
