RIVS has developed specialized aeration units for flotation machines
The development improves ore beneficiation efficiency. Learn more at booth C3027 at MiningWorld Russia 2026.
NPO RIVS, a Russian developer and manufacturer of equipment for the mining and processing industry, has completed the development of innovative aeration units for large-capacity flotation machines. The new aeration units are designed for specific ore types and are aimed at increasing the efficiency of its beneficiation.
Industrial test results have shown that specialized RIVS aeration units increase the extraction of useful components by 2–3%, depending on the ore.
For example, for every hundred tons of processed copper-containing rock mass, the plant will additionally produce 20–30 kg more metal in concentrate by using specialized aeration units.
To achieve this result, the developers optimized the design of the aeration units—the stator and impeller blades. In tall flotation machine bodies, these improvements help maintain laminar flow of the pulp-air mixture, minimizing the mechanical carryover of waste rock into the froth product.
The new development reduces energy consumption by 8–10% compared to similar products. This is made possible by flexible airflow adjustments, which influence the mechanism's ability to keep solid particles in suspension.
RIVS aeration units are a completely domestic development. They allow companies to replace imported equipment or upgrade obsolete equipment without compromising quality or efficiency, eliminating the need for foreign suppliers.
"The development of innovative components was made possible thanks to a subsidy allocated by the Ministry of Industry and Trade as part of the state R&D support program," notes Anatoly Khasyanov, CEO of JSC NPO RIVS. "We appreciate the government's support and assistance aimed at stimulating domestic innovation and the development of new technologies in the mining and processing industry."
