achieved under the optimized conditions. Key words: ion-absorbed-type rare-earth ore; leaching; depression mechanism; aluminum and iron impurity 1 Introduction Ion-absorbed-type rare-earth ore is a unique..., including Fujian, Guangdong, Hunan, Guangxi and Zhejiang. Most of such rare-earth ore deposits are associated with granite, mixed rocks, and other igneous rocks [1-3]. Ion-absorbed-type rare-earth ore......
Abstract: Magnetic separation of iron in rare-earth tailings was achieved by magnetizing roast process with coal as reductant. Effects of the temperature, carbon to oxygen ratio, and cooling type... which can be an important source of iron in the future. Main mining way of rare earth ore located at Bayan Obo in Baotou, China, is to extract iron. However, iron grade and iron recovery are only 50......
