Abstract: A process or use of at least one hydroxyl ether diamine for improving a process for froth flotation of silicates. Compared to the benchmark ether monoamines, ether diamines or mixtures thereof, the selectivity performance of the hydroxyl ether diamines is significantly better, delivering higher recoveries for the mineral of interest.
