Iron Ore Beneficiation Plant in Nigeria

Background

The customer's requirements for the final product are relatively high: grade ≥60%, raw material size ≤150mm, product size 0-10mm. the engineers of Central Asia Machinery recommended to use hydraulic cone crusher as the main crushing equipment, supplemented by jaw crusher after the field inspection. At the same time, the combination of ball mill and magnetic separator not only successfully completed the production task, but also exceeded the customer's expectations.

Solutions

• Crushing and screening stage: The process of three-stage crushing and screening with single closed-circuit stage was adopted.
• Grinding and magnetic separation stage: The process of stage-grinding and stage-separation was adopted.
• Concentrates dewatering stage: Magnetic concentrates were dewatered preliminarily by concentrated magnetic separator.
• 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.
