The design and development of selective flotation collectors has been the key to the remarkable success of flotation in beneficiating complex, difficult-to-process ores. It remains a challenging area of contemporary research in mineral processing.
Sustained research efforts over the past hundred years have led to delineating the scientific basis of selective mineral flotation in terms of the mineral crystal chemistry, surface and colloid chemistry of the mineral surface including its solubility, and the aqueous solution chemistry of the reagents. As illustrated in this work, a robust scientific molecular modeling framework to design flotation reagents, which accounts for all these aspects of mineral-reagent interactions, has been developed, and its application can significantly reduce the time and resources needed to design novel reagents.
