Iron Ore Dry Magnetic Separation Production Line and Process Solution

I. Overview of Iron Ore Dry Magnetic Separation Process

Iron ore dry magnetic separation process is a physical beneficiation method that utilizes the magnetic difference between magnetic minerals and non-magnetic minerals in the ore for sorting. This iron ore dry separation process is especially suitable for arid and water-scarce areas, through dry magnetic separation technology to realize efficient separation of iron ore, with simple process flow, low investment cost, environmental protection and energy saving and other significant advantages. We have developed a variety of dry magnetic separation process programs for different types of iron ore, which can meet different production needs.

Second, dry magnetic separation process for iron ore

1. Strong magnetic single magnetite ore processing

• Crushing system:

  • Jaw crusher coarse crushing

  • Hydraulic cone crusher in fine crushing

  • Product size: 10-30mm

• Dry Grinding:

  • Dry ball mill grinding

  • Graduated control of product fineness

• Dry Magnetic Separation:

  • Multi-stage dry magnetic separator

  • Concentrate grade can be more than 65%.

2. Strong magnetic polymetallic magnetite ore processing

• Weak magnetic separation-flotation combined process:

  • Dry magnetic separation to recover iron minerals

  • Tailings enter the flotation system

  • Flotation to recover sulfide/apatite

• Product Processing:

  • Dry dewatering of iron ore concentrate

  • Flotation concentrate filter drying
