Study on Preparation Technique of Rare Earth Minerals from Acid leach Dregs

摘要

The paper studies the preparation technique of RE minerals from acid leach dregs, and describes the preparation characteristic and process, using a combination process of gravity and flotation separation. The test results show that the combination process is the remarkable preparation technique of RE minerals from acid leach dregs. In order to determine optimum technical condition, the effect factors of preparation were investigated in the test. Simultaneously, the paper explores greatly possibilities in the comprehensively recovery of RE (chemical products inclusive) using the other techniques.
