Abstract

The invention discloses a combined collector for removing zirconite from pyrochlore ore, and a preparation method and application of the combined collector. The combined collector is prepared from oleic acid, a modified fatty acid collector, diesel oil and alkyl sodium sulfonate in a compounded mode. The combined collector has the high collecting ability to the zirconite, and the problems that a single fatty acid collector is low in zirconite removing rate and poor in technology stability. According to the combined collector, the synergistic effect between different chemicals is exerted advantageously, adsorbing of the chemicals on the surface of the zirconite is reinforced, the collecting ability of the collector to the zirconite is effectively improved, the combined collector is good insolubleness, poisonless and harmless, efficient and environmentally friendly, and the zirconite mineral is effectively removed.

Description

technical field [0001] The invention relates to a combined collector for removing zircon from pyrochlore ore, a preparation method and application thereof, and belongs to the technical field of mineral processing. Background technique [0002] Niobium is a rare metal with high melting point, corrosion resistance, good electrical conductivity, large thermal expansion coefficient, thermal conductivity, low temperature plasticity and good processing performance. Niobium is widely used in the fields of steel industry, aerospace, electronic reactor, low-temperature superconductivity and electronic industry, and is a very important strategic substance. [0003] Among the discovered niobium resources, about 90% of the niobium deposits are pyrochlore deposits. Pyrochlore mainly exists in two kinds of ores, that is, weathered residual laterite ore and alkaline carbonate ore. This type of pyrochlore ore also contains calcite and a small amount of magnetite in addition to pyrochlore. ...
