Our Cape Town and Johannesburg engineering teams have extensive experience in the analysis and design of long-distance slurry pipelines, mine waste and tailings disposal solutions, mine backfill systems, and mineral processing

The offices provide the full range of engineering services from concept studies through to detailed design and commissioning. Our capabilities also include the optimisation of existing operations through on-site process audits and investigations that lead to process improvements.

Our staff have commissioned many significant pipelines and mine backfill systems throughout Africa and have a clear understanding of the demanding requirements of working in remote regions.

The 1200 m² slurry test facility in Cape Town includes large-scale slurry pump and pipeline test loops of up to 300 mm in diameter, viscometers, thickening and filtration test facilities, mineral processing tests (crushing and abrasion index, scrubbing, magnetic separation, gravity separation, metal extraction and recovery, tailings treatment (cyanide and arsenic)), full scale cyclone test facilities, mine backfill and slurry materials characterisation, geochemistry (environmental), and geotechnical testing. Pilot plant test work is done to confirm the process flow sheet, and our portable testing equipment allows us to conduct bench top tests on site. The majority of our test work is completed in-house using our own specialised test equipment that includes an ICP analyser, UV-VIS spectrophotometer, and cyanide analyser, operated by qualified analytical chemists and process engineers.
