In view of the properties of iron ore from Yuanjiacun Iron Mine and technical puzzles for mineral processing therein, experimental study on its beneficiation technology was conducted with a proper flowsheet obtained. The proposed flowsheet consists of a one?stage of crushing, a semi?autogeneous grinding, a ball grinding, a low intensity magnetic separation, a high intensity magnetic separation, a regrinding and a reverse flotation with cationic collector. The flowsheet is relatively short without desliming step. With CY, a slime?endurable and low?temperature adaptable collector, iron concentrate with TFe grade and recovery exceeding 65% and 73%, respectively, can be prepared from low temperature flotation.
