AI Technical Summary
Technical Problem
Existing dihydroxyoxime acids are difficult to match with metal ions on the mineral surface during mineral flotation, resulting in poor flotation performance.
Method used
Dihydroxamic acid with a specific structure is synthesized by reacting succinic anhydride with alcohols and then with hydroxylamine, resulting in a dihydroxamic acid with a small-distance hydroxamic group, which is suitable for mineral flotation.
Benefits of technology
It improves the mineral flotation effect, enhances the adsorption strength and selectivity of the collector on the mineral surface, and increases the flotation recovery rate.

Abstract
The invention provides dihydroxamic acid and a synthesis method and application thereof, the dihydroxamic acid has a structure as shown in a formula M. The distance between two hydroximic groups in the structure of the dihydroxamic acid is appropriate, the distance between the dihydroxamic acid and metal ions on the surface of a mineral can be adjusted more easily to be matched, and an excellent flotation effect can be shown in mineral flotation.
