3,500t/d Iron Mineral Processing Plant in Nigeria

Background:

The metallic minerals were magnetite, hematite, limonite; the non-metallic mineral was quartz. Only Fe in the raw ores has recycling value, and the raw ores belong to original acid magnetite with low phosphorus and low sulphur.

Solution:

1 . Crushing and screening stage: The process of three-stage crushing and screening with single closed-circuit stage was adopted.

2 . Grinding and magnetic separation stage: The process of stage-grinding and stage-separation was adopted.

3 . Concentrates dewatering stage: Magnetic concentrates were dewatered preliminarily by concentrated magnetic separator.

4 . Tailings dewatering stage: The tailings were firstly processed by thickeners for the first-stage dewatering; after that, the underflow was transported by the slurry pump to hydrocyclone for classification.

Feedback：

The project adopted advanced, sound and energy-saving equipment and simple auxiliary facilities to cut construction costs and increase output. There was no environmental pollution, meaning that no waste water was discharged.
