Introduction
The document provides detailed information on the RCS™ flotation machines by Metso, designed to maximize flotation recovery and performance in ore processing plants. The machines utilize a circular tank concept combined with the DV™ (Deep Vane) mechanism to enhance flotation efficiency.

Flotation Concept
The RCS flotation machine integrates the benefits of circular cells with unique mechanism features to optimize conditions for roughing, cleaning, and scavenging duties. Metso offers a range of cell volumes from 0.8 to 200 m³ to meet modern ore processing requirements.

DV™ Flotation Mechanism
The DV™ mechanism features a unique impeller design with vertical vanes and an air dispersion shelf, promoting radial slurry pumping and minimizing sanding. It enhances flotation performance by maximizing particle-bubble contacts, ensuring effective solids suspension, and distributing air efficiently throughout the cell.

Cost Reduction and Maintenance
The mechanism is designed to minimize high-velocity zones, extending wear life. Impellers and diffusers are made from abrasion-resistant materials. The DV mechanism is easily removable for maintenance, and wear parts can be replaced without removing the mechanism.

Air Control and Drive Systems
Flotation air is supplied by a separate blower, with aeration rates controlled manually or automatically. The machines use V-belt drives for cell volumes up to 70 m³ and gearbox drives for larger volumes.

Tank Design Features
The circular tank design minimizes slurry short-circuiting and simplifies construction and installation. The tank supports the flotation mechanism and drive, with options for enclosing the cell top to reduce particle release.

Feed and Discharge
Standard feed, intermediate, and discharge boxes are used, with downflow control dart valves at the cell floor level.

Froth Handling and Level Control
Each tank includes double internal cross-flow launders for efficient froth removal. Froth crowder plates can be added to enhance recovery. Pulp level control is managed by pneumatically operated dart valves.

Specifications
The document provides detailed specifications for various RCS models, including cell volume, motor power, and air requirements. The machines are available with both V-belt and gearbox drives.

Conclusion
Metso's RCS flotation machines are designed to deliver maximum flotation recovery and performance, supported by decades of industry expertise and customer collaboration.
