Difficult to select iron ore beneficiation solution

Refractory Iron Ore Beneficiation Solution: OrePartner Realizes Efficient Recovery and Utilization of Iron Resources with Innovative Sorting Technology

Due to the complex mineral composition, fine embedded particle size, high impurity content, small magnetic difference and other characteristics of difficult to select iron ore, the traditional beneficiation methods have low recovery rate, concentrate grade is difficult to improve, a large number of iron resources can not be effectively utilized. How to break through the technical bottleneck of difficult iron ore beneficiation and realize efficient, economic and environmentally friendly iron ore sorting has become an important issue for raw material security in the iron and steel industry.

OrePartner, with its profound technical accumulation and innovation ability in the field of complex iron ore beneficiation, provides an integrated solution of pre-sorting and dumping - high-efficiency grinding - precise sorting - deep decontamination to help customers maximize the value of iron ore resources.

First, the core challenges of difficult to select iron ore processing

• Complex mineral composition: hematite, limonite, rhodochrosite, oolitic iron ore and other difficult to select a wide variety of iron ore.

• Fine embedded particle size: the embedded particle size of iron minerals is often less than 30μm, and it is difficult to dissociate the monomer.

• High content of impurities: silicon, aluminum, phosphorus, sulfur and other harmful impurities are difficult to separate.

• Small magnetic difference: low sorting efficiency of weakly magnetic iron minerals.

• Serious influence of slime: fine slime cover affects the sorting effect, and the consumption of chemicals is large.

OrePartner Refractory Iron Ore Beneficiation Technology System

We provide innovative solutions for the whole process from process mineralogy research, pre-sorting and dumping, high efficiency grinding, sorting process optimization to tailings treatment.

✅ Core service content:

1. In-depth analysis of ore properties
   Using MLA, XRD, optical microscope and other advanced means, we can accurately analyze the type of iron minerals, embedded characteristics, particle size distribution and impurities, and provide scientific basis for process design.

2. High-efficiency pre-sorting and waste disposal technology

   • Adopt pre-sorting technologies such as photoelectric sorting, XRT sorting, heavy media sorting, etc., to remove 20-40% of waste rock in advance.

   • Developing dry pre-sorting process, reducing water consumption, especially suitable for water-scarce areas.

3. Stage grinding - stage separation process

   • Adopt high-efficiency and energy-saving grinding equipment such as high-pressure roller mill and vertical mill.

   • Implementing the stage separation strategy of "collect as early as possible, throw as early as possible".

   • Optimize the grinding and grading cycle to reduce the phenomenon of over-crushing.

4. Joint sorting technology

   • Strong magnetic separation: adopt high gradient magnetic separator to recover weakly magnetic iron minerals.

   • Reverse flotation: develop highly efficient inhibitors and collectors to remove silicon and aluminum impurities in depth.

   • Re-election: using shaking table and spiral chute to separate coarse-grained iron ore.

   • Combined flotation and magnetic separation: adopting the combined flotation-magnetic separation process for complex iron ores.

5. Deep decontamination technology

   • Adopt reverse flotation to remove silicon and aluminum, so that the content of SiO₂ and Al₂O₃ is reduced to less than 2%.

   • Develop chemical leaching dephosphorization and desulfurization technology to solve the problem of harmful impurities.

   • Adopting magnetization roasting-weak magnetic separation process to deal with extremely difficult iron ore beneficiation.

6. Tailings treatment and resource utilization

   • Adopting high-efficiency concentration and filtration technology to realize dry stacking of tailings.

   • Recovering valuable components in tailings to improve the utilization rate of resources.

   • Carry out comprehensive utilization of tailings to make construction materials, etc.
