Blue Cube Systems, a technology company based in Stellenbosch, Western Cape, South Africa, designs, manufactures, distributes and supports in-line mineral quantification instrumentation.

We offer mineral process analysers, slurry stream analysers, chrome analysers, copper analysers and silica analysers.

In-line mineral quantifier

The company recently introduced state-of-the-art instrumentation for the in-line measurement of mineral grades in froth flotation concentrator plants.

The technology used in the flotation applications is a further development of the proven Blue Cube MQi in-line mineral quantifier. It is based on diffuse reflective spectroscopy combined with proprietary chemometric techniques, adapted for the measurement of froth slurries.

Blue Cube Systems designs, manufactures, distributes and supports in-line mineral quantification instrumentation.
Output from the Blue Cube MQi can easily be linked to the client's SCADA system.
The Blue Cube technology provides the required fast and reliable grade information.
The Blue Cube Analyser Optical Processor houses the Near UV - Infrared Spectrometer that collects the optical data.
The Blue Cube Analyser Data Processor provide the operator with client-scaled readouts of the three main measured elements or minerals.
The Scanhead is mounted in a unique spoolpiece mounted in the clients slurry stream; this in-line systems prevents blockages of typical online systems.
The Blue Cube Tempo Track has the ability to measure the froth velocity and height in real-time.

The technology can differentiate between different mineral versions of the ore eg copper oxide and copper sulphide.

Flotation plants for the measurement of froth slurries

In flotation plants, the final product must conform to the required grade specification, and at the same time, a satisfactory recovery must be maintained. To achieve optimal adjustment and the tuning of the flotation equipment, operators require reliable real-time information about the composition of mineral streams at various locations in the plant.

The Blue Cube technology provides the required fast and reliable grade information. It is a new method for rapidly determining in-line elemental and mineral concentration, enabling control and rapid stabilisation of the flotation circuit, as well as optimised settings for it.

Other applications

Units are also available for dry and solution applications and applications for the measurement of solutions are based on absorption spectroscopy and require a clear solution. Current examples include: composition measurement in heavy mineral sands and measurements of impurities in solution in the hydromet industry.

Installation and calibration of flotation instrumentation

Installation of the unit is easy and requires only minor mechanical alterations. Calibration of the unit is done against 4E fire assay, XRF or ICP analysis. Each Blue Cube MQi installation is connected to the company’s facilities in Stellenbosch by an internet data link. This enables supervision and calibration of the unit. The Blue Cube MQi technology can be installed at a relatively low capital cost and imposes very low operating costs. The company provides an ongoing product support service.

A total of 54 Blue Cube MQi units have already been installed at locations in South Africa, Namibia, Botswana, Zambia and Australia.

Mineral instrumentation hardware for processing plants

The Blue Cube MQi hardware package is very robust and was specifically developed for the harsh environments of mineral processing plants. It is intrinsically safe and contains no hazardous components such as radioactive isotopes, high-intensity lasers or high-temperature devices. The Blue Cube MQi carries CE certification.

Output from the Blue Cube MQi can easily be linked to the client’s SCADA system. Operators can now monitor product grade in real time and make rapid process adjustments to control the final grade close above the defined penalty grade while maintaining optimum recovery.

MQi Slurry Analyser

The MQi Slurry Analyser is used for an in-line measurement of Slurry Stream composition.

MQi Hydromet Analyser

The MQi Hydromet Analyser is used for an in-line measurement of the composition of solutions.

MQi Dry Analyser

The MQi Dry Analyser is used for the in-line measurement of dry free-flowing streams with grain sizes below 2mm.

MQi High Temperature Analyser

The MQi High Temperature Analyser is a new optical instrument built for high-temperature processes and it provides real-time quality data for significantly improved process control cycles.

Pre-amenability Studies

Quantitative full amenability studies are ideally performed on a set of 50 to 60 well-chosen samples with known compositions. A few additional 'unknown' samples may also be included for prediction of their analysis values.

Kamoa Copper Project, Katanga

The Kamoa Copper project is located in the Kolwezi District, Katanga, Democratic Republic of the Congo (DRC). The project includes an underground mine and a concentrator plant that produces blister copper and sulphuric acid.

High Grade Ore Through Accurate Data Collection

Blue Cube Slurry instruments are installed in-line and are suitable for slurry applications such as flotation operations, wet or dry magnetic separation, electrostatic separation, gravity separation and leach operations
