Technologies and Products

Advanced mineral processing

Selective Milling
Determine the force, feed input, and gap settings in your mill. This decreases possible damage and is more energy-efficient


Gravity separation
Spiral concentrators are simple low energy-consuming devices that separate minerals mainly on the basis of density or by shape.


Magnetic separation
Magnetic separation is the process of separating components of mixtures by using a magnet to attract magnetic substances.


Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic in mineral processing and recovery. 


Modular plant design

Plant modules

Pre-designed plants

Custom-designed plants



Our modular integration of sensor-based sorting solutions has been perfected over the past seven years allowing us to evaluate a problem and know when to go in and use our modular solutions, and when to suggest alternative answers.


We believe in applying simple solutions. There is no need to complicate matters. We have a simple process from the formation of a new plant to improving previously constructed brownfield projects that ensure our client's success every time.


We provide rapid results so that no time is lost, and you can see an instant return on investment. This is done through our modular solutions that can be ready within two weeks of arrival at their destination.
