Beneficiation of Refractory Amphibolite-Type Primary Ore from Yuanjiacun Iron Mine
Aiming at problems including low content of magnetic iron,fine dissemination size and high content of ferrous silicate in processing of the amphibole-type primary ore in Yuanjiacun Iron Mine,an experimental study was carried out by adopting a pre-concentration process consisting of fine crushing plus dry magnetic pulley separation and a roll grinding plus wet magnetic separation.The pre-enriched concentrate was then processed with a flowsheet including a three-stage grinding,a three-stage low-intensity magnetic separation and a reverse flotation,resulting in an iron concentrate grading 65.66%TFe at 49.31%recovery,with the yield of 21.45%.It is shown that iron resource can be utilized efficiently.
