Songatech is a premier supplier of natural Magnetite Powder, providing a high-density medium essential for coal washing and Dense Medium Separation (DMS). Our magnetite is selected for its high magnetic susceptibility and consistent particle size, ensuring stable suspension and sharp separation that lifts clean coal yield. On this page, we explain our magnetite grades and our supply capabilities across the coal and mineral sectors of South Africa.
High-Performance Magnetite Catalogue
Magnetite (Fe₃O₄) is the preferred medium for coal processing because it maintains density effectively and allows for near-complete recovery through magnetic separators. From our facility in Alrode, Alberton, we distribute these grades to major mining regions in Emalahleni, Middelburg, Newcastle, and Lephalale:
-
Standard Magnetite Powder: The balanced choice for drum washers in coal plants. It offers reliable medium behaviour and cost-effective performance for coarse separations.
-
Fine Magnetite Powder: Specifically designed for cyclone separations that require higher suspension stability and sharper cut points at the target Specific Gravity (SG).
-
Custom Magnetite Grades: Tailored to your plant design and specific coal characteristics, we can produce magnetite to your unique density or particle size requirements.

| Lead Time | Stock items typically dispatch within 24 to 48 hours |
Plant Efficiency and Quality Assurance
Songatech focuses on providing a recyclable medium that keeps your operating costs predictable and your yield high.
-
Stable Suspension: Our powder suspends well in water, ensuring a consistent medium density throughout the separation process.
-
Sharp Separation: Consistent particle size distribution allows for precise cut points, directly improving clean coal recovery.
-
High Magnetic Response: High susceptibility enables quick and easy recovery in wet drum separators, minimising consumption losses.
-
Strict QA: Every order is supplied with a Certificate of Analysis (COA) confirming particle size distribution, density, and moisture content.
Selection Guide for South African Coal Washing Plants
The correct grade selection depends on your circuit design and the separation density required:
-
Coal Washing (Drums): We recommend Standard Magnetite (90% < 75 μm). It is the most stable and cost-effective option for drum washers and coarse separations.
-
Coal Washing (Cyclones): Fine Magnetite (90% < 45 μm) is required to improve efficiency and density control in cyclone circuits.
-
Mineral DMS Circuits: Custom Magnetite grades can be tailored to specific target densities and unique mineral circuit designs.
