my country's rare earth carbonate precipitation production is automated for the first time

Issue Time:2020-07-15
The reporter learned from Baotou Rare Earth High-tech Zone on the 12th that the project of “Research and Industrialization of Continuous Production Process of Carbon Dioxide of Light Rare Earth Carbonate of North Rare Earth” was formally recognized as “the overall technology reached the international leading level” "And put into operation smoothly. This also marks the first time that my country has realized the continuous and automated production of rare earth carbonate precipitation in the rare earth industry.

  In the industrial production of rare earths, light rare earth carbonates are intermediate raw materials for a variety of rare earth products, and their uses are very wide. With the gradual expansion of the industrial scale after the integration of the rare earth industry, the problems of discontinuous operation and large amount of ammonia nitrogen wastewater in the intermittent precipitation process that used ammonium bicarbonate to prepare crystalline rare earth carbonate are very prominent, which restricts the light rare earth carbonate products. Further development.
