Description

technical field

[0001] The invention belongs to the technical field of mineral flotation, and in particular relates to a flotation composite collector and its preparation method and application. Background technique

[0002] Hydroxamic acid is a typical metal chelating agent. The hydroxyl oxygen atom and oxime nitrogen atom in the molecule can coordinate with most metal elements, usually forming a four-membered or five-membered ring chelate. Therefore, hydroxamic acid compounds are widely used in mineral flotation, metallurgy, medicine, water treatment and other fields.

[0003] In the field of mineral flotation, hydroxamic acid is an important type of flotation collector, which is widely used in the flotation separation of tungsten ore, cassiterite, ilmenite, rare earth ore and other minerals. The commonly used synthesis methods of hydroxamic acid compounds mainly include: hydroxylamine method, nitroalkane rearrangement method, nitroalkane reduction method, amine oxidation...
