RFC-Upscaling proposes the Reflux Flotation Cell (RFC) technology for mineral processing companies, with ROI in 3 – 4 years. Within the project, it is planned to commercialise the technology as a new product of FLSmidth for copper and iron ore. The RFC requires 30 % less capex and 20 % less opex compared to the existing flotation technologies.
