Hydroxamic acids are organic compounds gaining attention as eco-friendly collectors for froth flotation in the mining industry. With a hydroxamic acid functional group (-CONHOH), they form strong complexes with metal ions, making them effective for various minerals. Advantages include selectivity, pH versatility, biodegradability, lower toxicity, and synergistic effects with other reagents. Examples used in mining are potassium octyl hydroxamate, benzohydroxamic acid, and salicylhydroxamic acid. Despite higher costs and limited use compared to traditional collectors, hydroxamic acids show promise for sustainable mineral processing as research continues to optimize their performance and understand their mechanisms of action.
