Abstract

The invention relates to the technical field of beneficiation, in particular to an extremely low content magnetite beneficiation method and system for associated phosphate minerals. The method provided by the invention comprises the step of carrying out multi-stage sorting, namely finely grinding raw ore, carrying out dry separation on ore fines, carrying out superfine crushing by adopting a high-pressure grinding roller, then carrying out dry separation on middlings, and carrying out dry separation by adopting a V-shaped powder selecting machine and a dynamic powder selecting machine, so thatiron core concentrate and tailings are separated, the next wet type grinding and separation treatment capacity is reduced, grinding and separation energy consumption is reduced, water resource is saved, wetting tailing amount is reduced, and beneficiation cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to an ultra-lean magnetite mineral processing method and system of associated phosphorus minerals. Background technique [0002] Iron ore deposits in China are rich in reserves, but the grade is too low. Most of the iron ore is lean iron ore, and some are extremely low grade, which belongs to ultra-lean magnetite. The general grade is TFe10%-20%, MFe<5%. my country's ultra-poor magnetite resources amount to tens of billions of tons, of which Hebei and Liaoning provinces have more than 10 billion tons of ultra-poor magnetite resources. The research and development of ultra-lean magnetite can alleviate the contradictions of insufficient domestic ore supply and heavy dependence on imports of iron ore. [0003] The beneficiation method of ultra-lean magnetite mostly adopts magnetic pulley dry separation, tailing removal and crushing dry separation, and then directly enter...
