Abstract

A hydroxamic acid-metal hydroxide coordination complex and preparation and application thereof are disclosed. The hydroxamic acid-metal hydroxide coordination complex is formed by a coordination of hydroxamic acid with divalent or higher valent metal ions under an alkaline condition. The hydroxamic acid-metal hydroxide coordination complex has a strong selectivity and a strong collection ability for metal oxide minerals such as tungsten-containing minerals, ilmenite, rutile, cassiterite, and rare earth. The preparation method is simple and low in costs, and is beneficial to industrialized production.
