Company Profile

Blue Cube Systems (Pty) Ltd was established in 2001 with the purpose to develop, build and sell fast in-line mineral analysers for application in mineral beneficiation processes. A successful product, branded as the Blue Cube MQi in-line real-time mineral analyser, was developed with the financial support of the South African Innovation Fund and was successfully demonstrated during 2004. The company is located in Stellenbosch, the heartland of the Western Cape wine lands of South Africa. Since then 65 units were sold to clients in the R.S.A., Australia, Namibia, Botswana, Zambia and Chile. The company was funded by its shareholders and has no external debt.

The Blue Cube MQi product range include models suitable for slurry applications like flotation operations, wet or dry magnetic separation, electrostatic separation, gravity separation and leach operations.

The Blue Cube MQi equipment contains no hazardous component like X-ray generator or radiation sources. Therefore there are no licensing requirements or appointment of responsible person procedures.

The Blue Cube MQi technology is based on reflective spectroscopy for slurry and dry applications and absorption spectroscopy for solutions. Calibration is achieved by comparison of the spectral profile of a sample to that of samples with known composition. An in-line sampler is mounted next to the optical scanner to ensure a close link between the optical scanner and the physical calibration sample. Every Blue Cube MQi is linked to the technical centre of Blue Cube Systems by an internet link that enables remote calibration by specialist technicians.

Blue Cube Systems has recently also developed the Blue Cube TempoTrack, which can be used in conjunction with the MQi analyser or used independently for flotation control and optimisation.

The Blue Cube TempoTrack avails an indication of the relative air recovery in real-time through the measurement of the froth height above the lip as well as the tempo of the froth.

The build quality for all the products are robust and can handle the harsh conditions of a minerals separation plant. Output is by analogue or digital data channels for the Blue Cube MQi products and by profibus for the Blue Cube TempoTrack. The output is updated at 15 second intervals and can follow the process trends closely, satisfying the Nyquist norm for effective process control.
