Research Institute of Tungsten and Rare Earths of Jiangxi Province Cooperated with Enterprises to Develop Ion Rare-Earth Environmental Leaching and Sedimentation Technology Project

On November 25, 2016, Jiangxi Research Institute of Tungsten and Rare Earth and Guangxi Zhaxi Environmental Protection Technology Co., Ltd. formally signed the “Strategic Cooperation Agreement for the Research of Ionic Rare Earth Environmental Leaching Agents and Precipitation Agents”, and the two sides will work on environmentally friendly herbs. The in-depth cooperation in the mechanistic study of plant liquid leaching agents and precipitants, mine experiments, results transformation, application and promotion, etc., is the result of the hospital’s service to the construction of “China's rare golden valley” in Zhangzhou, which promotes the transformation and upgrading of rare earth industries and technological advancement of enterprises. An important measure will have a profound impact on the promotion of cleaner production and comprehensive utilization of ionic rare earths in the south.

It is reported that ammonium sulfate is commonly used as a leaching agent in the ion-absorption rare earth ore mining process in southern China. Improper treatment of the leaching method can cause ammonia nitrogen to remain in the tailings and mountains, resulting in contamination of groundwater, surface water, and soil ammonia-nitrogen. Mountain water and soil damage. The environmental protection herbal leaching agent and precipitant technology jointly developed by the Jiangxi Province Tungsten and Rare Earth Research Institute and Guangxi Shengzhao Environmental Protection Technology Co., Ltd. have both high leaching rate and recovery rate, and will not bring about environmental problems. Pollution and ecological destruction are in full compliance with the requirements of the current state for the promotion of green environmental leaching.

At present, the technology has achieved good experimental results after preliminary research and development and laboratory tests. The next step will be to carry out technical research work mainly in mine experiments, industrial experiments, etc. to accelerate the development of environmentally friendly herbal leaching agents. The comprehensive promotion and application of precipitant technology.
