Evonik offers advanced foam control solutions for the metals and mining industry, ensuring stable processing, improved throughput, and sustainable operations. Our portfolio includes the Arosurf® FC line of foam control additives and Surfynol® DF wetting agents, both designed to manage foam in critical mineral processing steps. These solutions are silicone-free, environmentally friendly, and can be tailored to specific ore types and process conditions.
Foam control is essential in mineral processing because unwanted foam often forms during flotation, slurry handling, and hydrometallurgical operations. Excess foam can reduce separation efficiency, cause equipment overflow, and lead to chemical and water losses. By using defoaming agents and antifoam solutions, mining operations can prevent these issues, optimize resource use, and maintain consistent process performance.
Arosurf® FC products suppress and break down foam in mineral processing circuits, reducing operational disruptions and improving efficiency. Surfynol® DF products, widely used in BIOX® and other hydrometallurgical processes, combine defoaming and wetting properties to enhance slurry handling and dispersion. Together, these solutions deliver reliable foam suppression without compromising mineral recovery, supporting both productivity and sustainability in modern mining.
