Magnetite Beneficiation Solutions

Solution Overview

Magnetite production line and process solutions provide a variety of modernized process options for magnetite ore beneficiation, including two major process routes: "weak magnetic - reverse flotation" and "full magnetic separation". Through the combination of new magnetic separation equipment and advanced processes, the grade of iron ore concentrate can be increased to more than 68% and the SiO₂ content can be reduced to less than 4.5%, which can satisfy the demand of modern iron and steel industry for high quality iron ore concentrate.

Magnetite ore beneficiation process details

Weak magnetization-reverse flotation process

Cation reverse flotation process:

• Stage grinding-weak magnetic separation (up to -0.074mm accounts for 80%)

• Fine sieve grading (sieve hole 0.1mm)

• Cation reverse flotation (one rougher and one finer)

• Froth product regrinding and re-election

• Concentrate grade up to 68.88

Anionic reverse flotation process:

• Weak Magnetic Separation Roughing

• Thickening and dewatering

• Anionic reverse flotation (one roughing and three sweeps)

• Concentrate grade up to 67.22

Full Magnetic Separation Process

• Three-stage grinding-magnetic separation (90% to -0.045mm)

• High-frequency fine screen grading (0.075mm mesh)

• Magnetic Separation Column Concentration

• Middle ore regrinding and re-separation

• Concentrate grade up to 69
