Iron Ore

High-Grade Magnetite for Non-Metallurgical Industries

Iron ore has been at the core of UMI’s business since inception, establishing us as a trusted global supplier to the coal washing and industrial processing sectors. Magnetite (Fe₃O₄) is the industry standard dense medium used in heavy-media separation circuits worldwide, and our expertise in sourcing and supplying premium natural magnetite ensures customers receive material that meets the highest standards of purity, particle size distribution, and magnetic performance.

UMI supplies both 83 Grade and 80 Grade Magnetite, specifically optimized for DMS and HMS circuits. Backed by long-term supply agreements, rigorous quality assurance, and expert technical support, we deliver consistent circuit performance tailored to your equipment and feed characteristics — helping maximize throughput, improve recovery, and reduce operating costs.

Magnetite

Magnetite (Fe₃O₄) is one of the world’s primary iron ore minerals and the most magnetic naturally occurring mineral on Earth. Its unique ferrimagnetic properties make it exceptionally valuable across a wide range of industrial applications. Mined and processed to exacting standards, magnetite is used as a high performance iron ore and as a critical material in dense medium separation, mineral beneficiation, recycling, and other advanced processing industries.

83 Grade Magnetite

Our 83 Grade Magnetite is engineered for dense medium separation (DMS) circuits, delivering superior suspension stability, low viscosity, and outstanding magnetic recovery. It maintains consistent medium density in cyclones and heavy-media baths, resulting in precise separation performance and improved clean coal yield. Beyond DMS, this grade also performs reliably in black pigment manufacturing, ferric sulfate production, and specialty fertilizer applications.

80 Grade Magnetite

Our 80 Grade Magnetite is built for high performance dense medium separation (DMS) and mineral beneficiation applications where a broader particle size distribution delivers optimal results. It produces stable, low-viscosity slurries for efficient gravity separation, provides exceptional magnetic recoverability, and is trusted across coal preparation, wastewater treatment, and specialty fertilizer industries for consistent, dependable performance.

Supporting Dense Medium Separation (DMS)

Dense Medium Separation (DMS) is one of the most effective gravity-based beneficiation methods used in mining and recycling. By suspending finely milled magnetite in water, operators create a stable medium of precise density that separates valuable material from waste. In coal preparation, clean coal floats while rock, shale, and pyrite sink, significantly reducing ash content. DMS is also widely used in lithium and critical mineral processing, as well as scrap metal recycling. Its versatility, accuracy, and cost-effectiveness make magnetite essential for modern resource recovery operations.

Logistics

From stevedoring at international ports to final unloading at your facility, UMI oversees every stage of the logistics chain with precision. Through trusted partnerships with terminal operators and transport providers, we ensure efficient, secure handling across all transport modes — delivering your material safely and on schedule.
