SIMPLE-WORKFLOW MAGNETITE BENEFICIATION PROCESS AND SYSTEM

WIPO Patent Application WO/2022/095145

A1

A simple-workflow magnetite beneficiation process, which relates to the technical field of beneficiation. The process comprises two-stage crushing, ultrafine crushing by two-stage high pressure grinding rolls, one-stage vertical grinding, grading four times and sorting eight times, thereby greatly shortening the process workflow. In addition, in the process, a high-pressure roller mill is used instead of a traditional fine crushing machine, and raw ore is crushed to be 0.5mm or less by using high pressure grinding rolls crushing technology in series, thereby greatly reducing the granularity of the ground ore. The simple-workflow magnetite beneficiation process allows a large number of auxiliary apparatuses and facilities such as belt conveyors, pumps, pipes, and dust removers to be dispensed with. Further provided is a simple-workflow magnetite beneficiation system.
