Abstract: Taking the tailings of crushed mica mine by wind in Lingshou county, Hebei province as a case, the beneficiation tests to make comprehensive recycling of iron minerals, monazite and zircon were made. The results showed that heavy minerals were concentrated by the cleaning table from the tailings, and the heavy minerals were concentrated by the joint process of low intensity magnetic separation-wet high intensity magnetic separation-dry high intensity magnetic separation-gravity separation by tabling. Then, Iron concentrate with Fe grade of 60.86% and recovery of 74.27%, monazite concentrate with REO grade of 61.13% and recovery of 70.36%, and zircon concentrate with (Zr,Hf)O₂ grade of 60.38% and recovery of 65.64% were obtained respectively.
