Mining technology of rare earth ore
Commonly used rare earth mining technology The technology of ionic rare earth is the independent intellectual property right owned by China. The Zhangzhou Nonferrous Metallurgy Research Institute is the main unit for the discovery and naming of ion-adsorbed rare earth minerals in China and the scientific and technological achievements of the second-generation rare earth extraction process. At the time, he was appointed as the deputy director of the research and the post of director of the Zhangzhou Nonferrous Metallurgy Research Institute. As the main participant and leader of the invention and application of the second generation extraction process of ionic rare earth ore, the historical development of this event. Have an unforgettable memory. In response to the reporter's covenant, Comrade Ding Jiaxuan made a comprehensive and systematic review and summary of this historical event. In 1970, in the past 175 years of development and utilization of rare earth mineral resources, it was found that there are as many as 200 minerals containing rare earth elements and their compounds in nature. However, there are only a few rare earth mineral raw materials that actually have industrial use value, and the number is about ten. There are monazite, cerite, bastnaesite, gadolinite, xenotime, allanite, niobium xenotime, euxenite. But these minerals containing a certain amount of most of uranium or thorium, and rare earth minerals are solid, mineral mineral phase states exist, they are often associated with a radioactive element or a symbiotic.
