Our ore, our lines,our own quality control.

Unlike a trader or a single-step processor, Dean Industrial runs mining, beneficiation, milling and testing as one system.

  1. 01

    Controlled source

    Our own mines feed the plant, so supply stays steady whatever the market does.

  2. 02

    Complete process

    Crushing, optical sorting, flotation, drying and dry milling — lumps and powders alike.

  3. 03

    Traceable quality

    One company from mine to bag, with clear responsibility at every step.

  4. 04

    Reliable delivery

    Capacity of 60,000 t of powder and 12,000 t of lumps a year keeps orders flowing.

No. 003 — Flowsheet

One flowsheet,four product streams.

Schematic only. See Products for full specifications.

No. 004 — Step by step

Eleven steps,all in our own hands.

  1. Mining

    Mining

    Our Minfeng and Dazhu mines are developed through adits, with rail haulage and LHD loaders underground, under the rule of safety first.

    • Own mines
    • Adit mining
    • ≈ 60,000 t / yr per mine
    Mining
  2. Haulage

    Haulage

    Ore travels by road from the mines to the plant, where it is stockpiled and blended for a steady, continuous feed.

    • Direct from the mine
    • Stockpiled
    Haulage
  3. Crushing

    Jaw crushing

    Jaw crushers and screens reduce the ore to size and grade it, feeding the sorters, the mills and the dry-milling line.

    • Screening
    Jaw crushing
  4. Sorting

    Optical sorting

    Optical sorters have replaced hand-picking. High-grade lumps become lump fluorspar — our 85-grade goes straight to steel mills and other buyers. The rest goes on to grinding and flotation, and barren rock is sold as construction aggregate.

    • Replaces hand-picking
    • 85-grade to steel mills
    • Waste rock as aggregate
    Optical sorting
  5. Grinding

    Grinding

    Ball mills with spiral classifiers grind the ore to the right fineness and send the slurry to flotation.

    • Spiral classifier
    Grinding
  6. Flotation

    Flotation

    The flotation line runs one rougher and three scavenger stages to produce high-grade concentrate at up to 98% CaF₂.

    • One rougher, three scavengers
    • CaF2 ≤ 98%
    Flotation
  7. Dewatering

    Filtration

    Filter presses and vacuum disc filters dewater the concentrate into wet fluorspar concentrate.

  8. Drying

    Drying

    Wet concentrate is air-dried in the drying hall; the drying line turns it into low-moisture dried concentrate, 70–80 mesh.

    • Drying hall
    • Drying line
    • 70–80 mesh

  9. Milling

    Dry milling

    Our large dry-milling line grinds and classifies fluorspar into 50–325 mesh powder across grades from 70% to 98% CaF₂.

    • 50–325 mesh
    • CaF2 70–98%

  10. Assay

    Assay

    Our laboratory tests every lot for CaF₂, SiO₂, sulphur and phosphorus so that what leaves the gate matches the contract.

  11. Dispatch

    Dispatch

    Wide-span warehouses with overhead cranes hold the finished product in bulk bags, zoned by grade, ready for large orders.

    • Bulk bags
    • Overhead cranes
    • Volume delivery
