摘要
介绍了一种用于湿法锌冶炼清洁生产的高效除铁方法,与传统的赤铁矿除铁法比较,在中温中压条件下进行,能耗较低,铁渣可回收利用,由于国内大规模锌精矿加压氧浸工厂的建成投产,加压氧浸技术及设备的工程化难题在国内可以解决,高效除铁法将是一种发展方向。
This paper introduces the process of iron removal in zinc hydro- metallurgy. Comparing with the traditional hematite process,it is operating under medium temperature and pressure,better in energy saving and the hematite can be recycled. Due to the big zinc pressure leaching plant being completed in china,the problems of pressure leaching technology and equipment have been solved,the high- efficient process of iron removal will be developed.
