Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. ... The iron ore magnetite, Fe 3 O 4, is ferrimagnetic. It can be separated from abundant deposits of taconite by grinding to a fine slurry in water.

When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.

The tailings, hydrocyclone overflow, on the other hand, are fed to a tailings thickener. The overflow of the tailings thickener (clarified water) is recirculated back and caters to the process water requirement of the plant. The recovered process water from the tailings thickener overflow of about 90–95% is recycled back to the process plant.
