Abstract

This invention provides a reagent composition and beneficiation method for lithium-tantalum-niobium polymetallic ore beneficiation, belonging to the field of lithium-tantalum-niobium ore beneficiation technology. The lithium-tantalum-niobium polymetallic ore beneficiation composition provided by this invention significantly improves desliming efficiency by precisely controlling the ratio of organic polyacrylamide compounds, polychlorinated compounds, and inorganic substances in the desliming reagent. The flotation collector, by precisely controlling the ratio of amine compounds, organic acids, and organic sulfonates, is used in the lithium-tantalum-niobium polymetallic ore beneficiation method proposed in this invention, which involves "magnetic pre-removal of non-magnetic gangue – lithium ore flotation separation – tantalum-niobium ore gravity concentration enrichment," achieving improved quality and efficiency in the flotation process. The reagent composition combined with the beneficiation method proposed in this invention, when applied to the beneficiation of lithium-tantalum-niobium polymetallic ore, improves beneficiation efficiency and reduces beneficiation costs.
