Ferrosilicon Powder • Dense Medium Separation

Stable density, sharp cut points, lower consumption

Songatech supplies gas-atomised ferrosilicon powder that gives dense medium circuits the edge. Spherical particles hold density, separate cleanly, and recover fast. Plants choose Songatech to keep SG steady and yield high, shift after shift.

Key facts

  • Composition: Iron–silicon alloy, gas-atomised for spherical particle shape
  • Grades: Coarse, Fine, Cyclone 60, Cyclone 40, DMS 70
  • Applications: DMS cyclones, Wemco drums, baths, gravity separation circuits
  • Density control: Maintains cut points between 2.7 and 3.5 SG
  • Recovery: High magnetic susceptibility for efficient medium recovery
  • Packaging: 1 t bulk bags or 250 kg drums
  • Lead time: Stock dispatch within 24 to 48 hours

Overview

Ferrosilicon powder is central to DMS efficiency. Gas atomisation creates clean, spherical particles with tight sizing. The result is a stable suspension that is easy to recover magnetically. Selecting the correct grade keeps density on target, cut points sharp, and operating cost predictable.

Benefits that make Songatech the easy choice

  • High stability in suspension that reduces medium loss
  • Sharp density separation for better recovery and yield
  • Consistent particle size distribution across grades
  • Strong magnetic properties for rapid recovery
  • Lower contamination and oxidation from gas-atomised surface
  • Full range of grades for coarse and fine duties

Coarse Grade

Built for Wemco drums and baths. Holds density at coarser cut points and recovers cleanly with low losses.

Drums and baths

Fine Grade

Best for cyclone duties needing fine separation. Stable at lower densities and improves recovery of fine valuables.

Cyclone duty

Cyclone 60 and Cyclone 40

Optimised blends for DMS cyclones at SG 2.8 to 3.4. Strong magnetic response supports fast and efficient recovery.

Optimised blends

DMS 70

Extra-fine grade for very high density separations above SG 3.4. Delivers extremely sharp cut points in specialised cyclone circuits.

High SG specialist

Quality assurance

  • Controlled particle size distribution testing per batch
  • Magnetic susceptibility and density checks
  • Chemical composition verification
  • Certificates of analysis and full traceability

Frequently asked questions

Grade choiceWhich ferrosilicon grade should be used
Coarse for Wemco drums and baths. Fine for cyclones. Cyclone 40 and 60 suit most circuits where accuracy and recovery must be balanced. DMS 70 for very high density separations.
RecoveryHow is ferrosilicon recovered
By magnetic separators placed after the DMS circuit. High magnetic susceptibility ensures efficient recovery with minimal losses.
Service lifeDoes gas-atomised ferrosilicon last longer
Yes. The spherical, clean surface reduces oxidation and keeps the medium stable, which lowers consumption compared to milled alternatives.

Note. Final grade depends on target SG, circuit design, and ore type.

Selection guide
