Addressing the demand for more sustainable and less toxic collectors for the future, offering completely new chemistries.

New, Sustainable Flotation Collectors

The main objective of iron ore flotation is to upgrade the concentrate by removing silicates and/or phosphorus-containing minerals.

The use of silica flotation has increased in recent decades. The trend will continue as more complex ores have to be mined and higher-grade iron ore concentrates with fewer impurities are requested by the steel industry. We are also offering new solutions to meet the demand for more sustainable, less toxic collectors.

For more than 25 years, we have been developing flotation collectors in close collaboration with the industry both for magnetite and hematite systems. We have developed new methodologies to study froth characteristics that complement the traditional flotation tests. This is the foundation for our ability to successfully progress from the lab to full-scale plant conditions.
