quick-release spigot system simplifies adjustments and minimises downtime. Key design features included: Lightweight construction: Weighing just 44.6 kg, the cyclone can be easily manoeuvred by operators for installation, handling and maintenance. Durable build: A steel rubber-lined inlet head and cone, with a 15 mm replaceable liner ensure wear resistance and a long service life. Quick-change spigot system: A lightweight, tool-free screw coupling enables operators to replace spigot rapidly without shutdowns. Since spigot diameter directly influences product quality and deposition accuracy, this feature is critical to TSF stability. Flexible operation: Interchangeable spigots, vortex finders, and cone angle options (10° and 20°) give operators control across different stages of TSF development. Optional movable stands/skids: Improve cyclone relocation efficiency while reducing labour requirements. Earlier in 2025, Multotec received an order for upwards off 200 GV250 Cyclones, for one of the client’s existing TSFs. Manufacturing is underway, with delivery scheduled before the end of 2025, and the field service team will provide on-site installation support and training to ensure a reliable performance from day one. Delivering results: efficiency, safety, sustainability Although the GV Cyclones are yet to be commissioned, installations at other sites traditional open spigot deposition, reducing labour intensity, lowering operational costs, and giving operators precise control over dam wall height,” says Erick Herbst, Territory Sales Manager - Capital at Multotec. By ensuring even material distribution, the GV Cyclones improve water recovery, and aid in the correct material characteristics depositing on the TSF wall, contributing to safer and more sustainable long-term TSF management. With their balance of durability, lightweight handling, and operator-friendly features, Multotec’s GV Cyclones are setting a new benchmark for safer, more sustainable tailings management. n already highlight their benefits. “Cyclones enable a faster, more controlled rate of rise compared to

demonstrating Multotec’s commitment to delivering fit-for-purpose solutions that add real value on site. “The GV Cyclones were designed with operators in mind. Features like the lightweight body, interchangeable cone angles, and quick-release spigots make day-to-day management easier and safer, while still delivering the durability needed for harsh conditions,” explains Blane Pillai, Applications Engineer at Multotec. The GV Cyclones are engineered to deliver the optimal volumetric split between overflow and underflow to meet TSF rate- of-rise requirements. Their configuration can be adjusted as deposition conditions evolve, ensuring consistent performance even if the characteristics of the ore entering the processing plant change. Built to absorb pressure spikes during start-up, the cyclones offer stability under demanding conditions, while the
work, supported by on-site comparative equipment trials. These trials evaluated material behaviour, confirmed achievable recoveries, and provided accurate tailings samples for further testing. To ensure reliability, Multotec engineers oversaw sampling procedures to eliminate bias, giving the client confidence in the final configuration. The cyclone’s performance depends on factors such as length, cone angle, spigot size, and vortex finder selection. Multotec’s GV Cyclones can be supplied with either a 10° or 20° cone angle, allowing operators to balance ease of handling with fine performance control. For this project, Multotec customised the inlet head size and overflow elbow flange to integrate seamlessly with the client’s existing pipework. This removed the need for auxiliary adaptor equipment and reduced the weight of the cyclone,
