摘要
针对袁家村铁矿闪石型原生矿存在的磁性铁占比低、嵌布粒度微细、硅酸铁含量高等问题,进行了选矿试验研究。预选采用细碎-磁滑轮干选和辊磨-湿式磁选,预选精矿经三段磨矿、三段弱磁选、反浮选流程,获得了产率21.45%、TFe品位65.66%、回收率49.31%的铁精矿,实现了资源高效利用。
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.
