In cassiterite flotation, collectors like fatty acids, phosphoric acids, arsenic acids, and hydroxamic acids are commonly used. [10], [11], [12].Among them, benzohydroxamic acid (BHA) is frequently employed due to its strong metal coordination capabilities, easy availability, and non-toxic nature [13].Nevertheless, the practical use of …
