Experiments and production practice of recovering iron from floatation tailings of gold mine;

Study on table concentration of flotation tailings;

Recovery of fine scheelites from flotation tailings by flotation column

Iron content in flotation tailings of bauxite is high,so the tailings cannot be directly used as raw materials for producing primary Al-Si alloy.

To comprehensively utilize the reverse flotation tailings,the beneficiation test was carried out,and the regrinding and reprocessing was used in production practice,the magnetic iron mineral in the tailings was recovered once again, and the grade of iron concentrate reached 65.
