Mica beneficiation solutions: innovative application of combined re-election and flotation processes

As an important non-metallic mineral resource, the beneficiation process of mica varies significantly depending on the type of mica and embedding characteristics. This mica beneficiation solution mainly focuses on the specialized beneficiation process for large-sized mica and fragmented mica, including the core technologies of hand separation, friction beneficiation, air separation and flotation, as well as the configuration of the supporting equipment and technological advantages, to provide a comprehensive solution for the efficient recovery and purification of mica resources.

I. Characteristics and challenges of mica beneficiation

Mica beneficiation faces the following technical challenges:

• Diversity of species: divided into three major categories of white mica, black mica and lithium mica, with large differences in physical and chemical properties.

• Complex embedding characteristics: from large mica to fine flakes, different separation processes are needed.

• High separation difficulty: similar properties with feldspar, quartz and other vein minerals, high separation efficiency is required.

• Diversified product requirements: different application fields have different requirements on particle size and purity of mica products.

Second, the core mica beneficiation process program

1. Large-size mica beneficiation process

• Hand-selecting process: manual selection of large-size mica flakes, suitable for high-quality mica recovery.

• Friction beneficiation: utilizing the difference in friction coefficients between the mica flake structure and the vein minerals for sorting.

• Shape sorting: separating flake mica and granular vein minerals by special screening equipment.

2. Debris mica beneficiation process

• Air separation process: utilizing airflow sorting, suitable for mica beneficiation in dry areas.

• Flotation process: using anionic collector, flotation of mica in acidic or alkaline medium.

• Combined process: re-election pre-selection + flotation purification, to improve the efficiency and recovery of sorting

Third, re-election + flotation combined process flow

1. Grinding and classifying stage

• Wet grinding: use wet energy-saving lattice-type ball mill for grinding and dissociation.

• Classification processing: high frequency fine screen classification, to ensure that the separation of the feed size qualified

• Concentration control: accurately control the slurry concentration to create conditions for subsequent sorting.

2. Re-election separation stage

• Spiral chute roughing: preliminary separation of mica and heavy minerals.

• Shaking table selection: further remove the sand impurities mixed in the mica flakes.

• High-efficiency sorting: separating heavy sand (magnetite and zircon), light sand (feldspar and quartz), flake mica and sludge.

3. Flotation separation stage

• Acid flotation: flotation of mica under acidic conditions using anionic traps.

• Alkaline flotation: recovery of fine-grained mica with anionic recovery agents in an alkaline environment

• Optimization of pharmaceutical system: adjusting the dosage of trapping agent and adjusting agent according to the type of mica.
