Mineral Technologies offers modular Dense Media Separation plants across a wide range of capacities and applications. Each plant is designed around the mineral DNA of the orebody, ensuring stable separation performance under real operating conditions.
Two representative examples of our modular plant families are shown below. The mt DMS C-Series focuses on compact and flexible installations, while the mt DMS M-Series is designed for larger throughputs and more demanding processing environments.
mt DMS (plants)
Many DMS plants are built from similar equipment. What makes the difference is how the circuit is engineered. Mineral Technologies designs modular DMS plants around the mineral DNA of each deposit, applying decades of fine mineral processing expertise to optimise feed preparation, cyclone stability, medium management and plant maintainability, delivering predictable recovery, controlled FeSi consumption and faster ramp-up.

Full capacity range
mt DMS plants cover capacities from approximately 10 tonnes per hour to 4,000 tonnes per hour, each engineered around the orebody, separation target and operating context of the mine.
Simple physics. Demanding execution.
Dense Media Separation uses a simple principle: particles with different densities behave differently in a dense liquid.
By mixing crushed ore with a slurry containing ferrosilicon (FeSi), operators create a medium with a carefully controlled density. Particles lighter than the medium float, while heavier particles sink.
This allows valuable minerals to be separated from waste based purely on apparent density.
DMS operates most effectively within a defined particle size range. In typical applications, material between approximately 0.5 mm and 50 mm is treated, with some applications extending up to 100 mm depending on the ore characteristics and plant design.
This makes DMS fundamentally different from fine particle processes such as flotation, which operate on much smaller particle sizes. Instead, DMS targets the coarse fraction of the ore — where large volumes of waste can be rejected early in the process.
Gravity separation vs density separation
In conventional gravity separation, particles settle slowly according to their natural density differences. In Dense Media Separation, the process is accelerated and controlled by suspending particles in a dense medium that immediately forces the separation.
Inside a DMS cyclone, the slurry is exposed to strong centrifugal forces that further intensify the separation. Heavier particles move outward and report to the sink product, while lighter material exits through the float stream.
The medium is then recovered through drain, rinse and magnetic circuits before being returned to the process.
Where experience matters
While the principle is straightforward, maintaining stable separation conditions is where expertise becomes critical.
Separation efficiency depends on:
- consistent medium density
- well-prepared feed material
- stable cyclone pressure and flow conditions
- efficient recovery of the ferrosilicon medium
Small deviations like excess fines, unstable pressure or medium losses can quickly reduce recovery and increase operating costs.
That is why mt DMS plants are engineered not only for separation itself, but for maintaining stable process conditions throughout the entire circuit.
Where experience shapes performance
In a DMS plant, the equipment itself is well understood. Screens, pumps, cyclones and magnets all have known specifications and behaviour. The difference lies in how these elements are integrated and tuned to match the characteristics of the orebody.
At Mineral Technologies, plant design begins with understanding the mineral DNA of the deposit. Test work determines the density behaviour of the ore and defines the optimal separation window. From there, the plant is configured to maintain those conditions consistently in real operation—even as parts wear and operating conditions evolve over time.
-
Feed preparation
Proper screening protects the medium from excessive slimes and ensures particles enter the cyclone in the correct size range for efficient separation.
-
Medium conditioning and mixing
Carefully designed mixing boxes maintain consistent density and prevent issues such as rafting or uneven distribution.
-
Cyclone control
Stable feed pressure and correct medium density ensure reliable separation efficiency and predictable product quality.
-
Medium recovery circuit
Drain and rinse screens plus magnetic recovery return ferrosilicon to the process and help keep operating costs under control.
-
Designed for real operating conditions
Pumps, which experience significant wear in dense medium circuits, are positioned for quick access and replacement, ensuring the plant maintains performance and availability with minimal downtime.
