Material introduction

Stage grinding, stage separation, high separation efficiency; Combined use of multiple processes, green and environmental protection; Strong magnetic tail throwing-reverse flotation process to ensure concentrate grade.

The hematite beneficiation process can be applied to hematite and impurity khenbu with uneven particle size and high fine-grained content, including a small amount of magnetite, gangue minerals containing quartz, kaolin and other ore complex hematite.

Stage grinding, reduce follow-up operations and reduce costs

The first stage of grinding and grading adopts ball mill and cyclone to form closed-circuit grinding, which can not only ensure the classification efficiency but also ensure the classification granularity; And through the high gradient magnetic separator, some low-grade tailings can be discarded, which can not only reduce the amount of regrinding of medium ore, but also avoid overgrinding and reduce metal loss.

Adopt magnetic separation-flotation combined process, green and environmental protection

The magnetic separation operation separates qualified coarse-grained concentrates and tailings in time, which conforms to the principle of early harvest and early abandonment, and reduces the amount of flotation operations and costs.

Strong magnetic tail throw, provide flotation conditions

The strong magnetic process can recover fine-grained iron minerals, which can play the dual role of desliming and tail throwing, creating better conditions for flotation operations;

Reverse flotation process, float less and suppress more

The reagent system of the reverse flotation process is simple, which can significantly reduce the entry of organic substances such as flotation reagents into the pulp and reduce its adverse effects on the flotation process.

Advantages

  • Advantage one

    1. According to the ore composition, you can freely choose the matching model.

  • Advantage two

    2. The whole system reduces energy consumption and improves recovery rate.

  • Advantage three

    3. Small footprint, convenient operation and higher beneficiation efficiency.

  • Advantage four

    4. The discharge material can reach the standard concentrate index, which is environmentally friendly and pollution-free.
