Description

Flotation reagent and flotation process for vanadium titano-magnetite titanium concentrate Technical Field The invention belongs to the field of vanadium titano-magnetite flotation, and particularly relates to a vanadium titano-magnetite titanium concentrate flotation reagent and a flotation process. Background In flotation, because a single agent cannot achieve an ideal flotation effect, a synergistic effect principle of agents is utilized to achieve better flotation effect and economic benefit through the combined use of two or more agents. The synergistic effect means that a plurality of medicaments are matched and combined according to a certain proportion, and the flotation performance of the mineral is better than that of the single medicament. In recent years, the synergistic inter-working of collectors has become an important trend in the ilmenite flotation industry. Commonly used are combined collectors of fatty acid-neutral oil, chelating collector-nonpolar hydrocarbon oil, and the like. Currently, ilmenite collectors have been studied more comprehensively, and widely used flotation agents mainly comprise fatty acids, such as oleic acid, tall oil and the like, and other ilmenite collectors, such as hydroxamic acids, organic phosphonic acids, organic arsines and the like, have been studied and developed in recent years. In addition, the combined collectors used in the ilmenite flotation industry include F968, R-2, ZY, H717, and the like.
