FLSmidth Dorr-Oliver SuperCell Flotation Machine SC-30

The FLSmidth Dorr-Oliver SuperCell Flotation Machine SC-30 is a 30 m³ forced-air mechanical flotation cell designed for high-throughput base metal, phosphate, and industrial mineral flotation circuits. The SuperCell design combines the traditional Dorr-Oliver forced-air rotor-stator mechanism — known for its superior air dispersion and bubble size distribution — with an enlarged cell volume that reduces the number of cells required per bank, simplifying plant layout and reducing capital cost in large throughput applications. The SC-30 is positioned in the large-cell segment, appropriate for rougher and scavenger flotation duties in circuits processing 500–2000 t/h of ore feed.

The Dorr-Oliver forced-air rotor-stator is the defining feature that differentiates the SuperCell from self-aspirating mechanical flotation cells and from column flotation cells. The external forced-air blower delivers precisely controlled air volume to the rotor, which disperses it into fine bubbles with a precisely controlled bubble size distribution. Fine, uniform bubbles provide higher surface area per unit volume of air than coarse bubbles, improving mineral attachment probability and flotation kinetics for both fast-floating and slow-floating mineral species. The rotor speed is independently controllable, allowing the operator to optimise air dispersion independently of froth depth and reagent additions.

Maaden Phosphate Company's beneficiation plant at Wa'ad Al-Shamal — the world's single largest phosphate mining and processing complex — uses flotation as the core separation technology for removing silica, carbonate, and clay gangue from phosphate ore. The phosphate flotation circuit at MPC operates at massive scale, processing millions of tonnes of ore per year, and the selection of large, reliable flotation cells that minimise maintenance intervention and cell standby downtime is critical to plant availability and concentrate production targets. FLSmidth's SuperCell technology is proven in both phosphate and potash flotation circuits globally, providing direct application relevance for Saudi operations.
