Titanium rough concentrate concentration method

The invention discloses a titanium rough concentrate concentration method, and belongs to the technical field of mineral separation. The problems that in the prior art, after concentration, titanium concentrate is low in grade, the content of impurity elements such as silicon and calcium is high, the yield of the titanium concentrate is low, and water and electricity energy consumption is low are solved. According to the titanium rough concentrate concentration method, a raw material bin, a conveying device, a rod mill, a slurry pump pool, a cyclone, a low-intensity magnetic separator, a high-gradient drum-type magnetic separator, a concentrate concentration pool and a belt filter which are sequentially connected are included, and the low-intensity magnetic separator is further sequentially connected with an iron ore concentration pool and the belt filter; and the high-gradient drum-type magnetic separator is sequentially connected with a vertical ring strong magnetic separator, a tailing concentration tank a
