Problems solved by technology

[0004] However, the main problem existing in the prior art is that the existing collectors have poor adaptability to temperature, and the phenomenon that the summer index is good, the winter agent solubility is poor, the dosage is large, and the flotation index is poor, and the primary The unavoidable ions in the secondary slime and pulp generated during the slime and grinding process have a relatively adverse effect on flotation, resulting in large dosage of reagents and poor selectivity of reagents.

Abstract

The invention relates to the technical field of beneficiation engineering, in particular to a pegmatite-type spodumene flotation collecting agent and a preparation method and application thereof. Thepegmatite-type spodumene flotation collecting agent is mainly prepared from, by weight, 50-75 parts of petroleum sulfonate, 15-45 parts of a surfactant and 5-10 parts of an emulsifier. The preparationmethod comprises the steps that the emulsifier is dissolved in water and uniformly mixed with petroleum sulfonate and the surfactant. The flotation collecting agent is prepared by mixing and compounding the components above, the collecting capability and the selectivity under low-temperature conditions are both high, increase of the grade and recovery rate of spodumene concentrates is facilitated, and fluctuation of flotation indexes caused by temperature changes is reduced; the collector has high resistance to mud and calcium and magnesium ions, high applicability in mineral water and high adaptability to various kinds of pegmatite-type spodumene at different altitudes and areas, the usage of an adjusting agent can be decreased, and production technical indexes of a beneficiation factoryare stabilized.

Description

technical field [0001] The invention relates to the technical field of mineral processing engineering, in particular to a pegmatite-type spodumene flotation collector and a preparation method and application thereof. Background technique [0002] Lithium is an important energy metal, which has a wide range of uses in the field of industrial production, and has titles such as "industrial monosodium glutamate", "energy metal", and "white petroleum". In recent years, with the rapid development of industries such as new energy vehicles, high-end equipment manufacturing, strategic emerging industries, and nuclear power, the demand for lithium products has exploded. my country is very rich in lithium resources, with lithium reserves of about 3.2 million tons, accounting for 22% of the world's lithium reserves, ranking second in the world, mainly concentrated in the Qaidam Basin and the Qinghai-Tibet Plateau's salt lake lithium, accounting for the country's total reserves 85% of. ...
