Atrac® 922 collector for phosphate flotation, jointly developed by Nouryon and Yara, yields high performance and reduces environmental impact
June 5 – 10, 2022
Fatty alcohol ethoxylates are broadly used in collector formulations together with anionic surfactants mainly to enhance selectivity and efficiency. For decades, the industry regarded alkylphenol ethoxylates as cost- and performance-efficient flotation agents. However, environmental concerns have arisen around the use of alkylphenol ethoxylates which initiated a joint development between Nouryon and Yara Siilinjärvi to identify a replacement for alkylphenol ethoxylate in collector formulations used at Yara. This cooperation resulted in Nouryon’s introduction of the Atrac® 922 mineral flotation collector, an alkylphenol-free collector formulation that provides both environmental benefits as well as improved performance.
