Abstract
The present invention discloses a monazite and apatite paragenetic ore enrichment method. High-grade and high-recovery-rate monazite concentrate can be obtained by adopting the method through steps of ore grinding, floatation, magnetic separation and low-acid advanced leaching treatment and re-floatation. In this process, the applicable range of ore pulp temperature is wide, the process flow is short, the ore dressing conditions are mild, the energy consumption is small, the used diluted acid can be cyclically regenerated and used, the pollution is small, the environmental stress is small and the recovery rate of low-grade monazite and apatite paragenetic ores can be obviously improved.
