Abstract

The invention discloses a modified oleic acid type mineral flotation collecting agent and a preparation method thereof, wherein the modified oleic acid type mineral flotation collecting agent is prepared by acidizing and modifying oleic acid by using concentrated sulfuric acid, then extracting and purifying by using an extracting agent, saponifying and solubilizing by using a strong alkali solution, and finally activating by using a surfactant; the extracting agent is a saturated aqueous solution of lithium sulfate, sodium sulfate, potassium sulfate or ammonium sulfate, the strong alkali solution is a saturated aqueous solution of lithium hydroxide, sodium hydroxide or potassium hydroxide, and the surfactant is one or a mixture of at least two of OP-10, span-20, span-40, span-60 and span-80 and Tween-20, Tween-40, Tween-60 and Tween-80. According to the collecting agent, fluorite and other minerals can be efficiently recycled under the low-temperature condition, unit consumption of the agent is remarkably reduced, and the collecting agent is simple in preparation process, safe, environmentally friendly and easy for industrial production.

Description

technical field [0001] The invention relates to a mineral flotation collector and a preparation method thereof, in particular to a modified oleic acid type mineral flotation collector and a preparation method thereof. Background technique [0002] With the rapid development of the current industry, the global ore resources are getting poorer and poorer, and the distribution of useful minerals in the ore is getting finer and more complex. In addition, the material and chemical industries have more and more requirements and precision for material sorting. High, the role of mineral flotation is increasing. Because minerals, such as fluorite ore, ilmenite, rare earth ore, phosphate rock, scheelite, etc., have differences in hydrophobicity and hydrophilicity in their surface properties, flotation is just using this difference in gas-liquid- The minerals can be separated in the solid three-phase interface system. The collector refers to the flotation agent that makes the floatin...
