Cavex® hydrocyclone. The design features a laminar spiral inlet geometry, which allows the feed stream to blend smoothly with rotating slurry inside the chamber. This results in greatly reduced turbulence throughout the entire hydrocyclone, creating even wear, long life and efficient classification. Valves are critical to any minerals processing operation and Weir Minerals Africa can supply slurry, industrial and process valves for most applications, with brands Delta Industrial™ and Isogate® knife gate valves. These have been installed at many African mines and are known for their ability to perform in the most arduous conditions. Weir Minerals strengthened its tailings and water management offering in March 2018 when it concluded an agreement with international group Andritz to access its separation and dewatering technologies. These are marketed by Weir Minerals under the brand name IsoDry™ and include thicken- ers, filter presses, centrifuges and vacuum belt filters. Summing up the product range, Singleton says it is very diverse, incorporating many brands and prod- ucts across the entire field of mineral processing. “We provide all equipment in critical wear applica- tions in every single area of the minerals processing flowsheet.” Finally, on the subject of market conditions, Singleton says that there are relatively few green- field projects in South Africa but points out that Weir Minerals Africa is well positioned to support existing operations with its aftermarket and ser- vice offering. “Even when there is less investment in greenfield projects, mines still operate and there is a constant demand for parts and for the upgrade of existing equipment, so we remain busy in South Africa,” he notes. “In the rest of the continent, mining is quite buoy- ant – extremely so in West Africa, where we have

supplied a number of new gold mines and secured a significant order for a new iron ore project in Nigeria. In short, we’re doing extremely well in Africa, with business having expanded for nine consecutive years. We see the continent as a growth market of exceptional potential.” 
