The "KYR type rare earth collector" developed and produced by Baogang Group Mine Research Institute has recently completed industrial application tests. This marks a key technological advancement for Baogang Group in rare earth beneficiation, which will significantly improve the comprehensive utilization efficiency of rare earth resources in the Bayan Obo mining district.

The "KYR type rare earth collector" used in this industrial test is an important scientific research achievement in the development and application project of a new and efficient rare earth collector by the institute. The project team, in collaboration with Baoshan Mining Co, conducted comprehensive application verification on the rare earth flotation production line of Baogang's mineral processing operation department.

During the 34-day industrial trial period, the "KYR type rare earth collector" fully demonstrated its core advantages in sorting rare earth minerals with excellent testing indicators: high grade of rare earth concentrate, low impurity content, and large product output.

Data shows that in all 40 stable production test shifts, the weighted average grade of rare earth concentrate produced reached 60.83 percent, exceeding the preset experimental target. The average shift production of concentrate was 8.8 percent higher than the established experimental target. Both key indicators exceeded the target, proving that the agent can maintain stable and reliable separation performance in the face of varying production water quality and changing raw ore properties.

An institute representative said that the research and development work will focus on further improving the production and grade of rare earth concentrates, continuously reducing the harmful impurity content in concentrates, optimizing the cost and adaptability of reagents, and reducing the moisture content of concentrates, to improve the comprehensive utilization level of rare earth resources and provide stable and reliable raw material support for the sustainable development of China's strategic emerging industries.
