De Beers Technologies SA provides product delivery and support to the wider diamond mining industry.  The full product value chain is executed from R&D, commercialisation and full maintenance support. The product range includes high throughput large diamond X-Ray Transmission sorters, diamond X-ray sorters, laser Raman single particle sorters, magnetic roll separators, non-nuclear dense medium controllers as well as X-ray calibration tracers.  The latest development also includes the RhoVol particle density measuring unit.  DebTech provides full technical support, including spares, maintenance and repairs.  Metallurgical services are provided through technical plant audits and ore dressing studies.

The XRT sorters may have application in other minerals such as coal and iron ore.

The RhoVol system is designed to allow the fast measurement of the density profile of a process sample to facilitate plant monitoring and optimisation, with minimal sample preparation. The individual per particle mass and volume measurements are collated into a density profile histogram, tromp curve etc. for process performance analysis.  Particle size and shape information e.g. sieve size, elongation, compactness, roller gap size etc. are available per particle.  This information can be utilised to identify causes of separation anomalies.
