Problems solved by technology

[0004] At present, the main treatment process for this type of ore is a single positive flotation process. The positive flotation process uses multi-stage beneficiation to finally select qualified concentrates. The collector uses oleic acid fatty acid agents, but oleic acid is used as a collector. It has the disadvantages of poor water solubility, poor low temperature resistance, poor selectivity and very hard water resistance, low concentrate grade, large dosage and large index fluctuations
Especially in the environment where the temperature is low in the north, the pulp to be flotation must be heated above 20°C to ensure a good flotation effect, which will inevitably greatly increase the production cost

Abstract

The invention relates to a combined collecting agent for low-grade fluorite ore separation, and belongs to the technical field of mineral processing, the combined collecting agent mainly comprises the following raw materials in percentage by mass: 55-70% of acid oil, 10-25% of C14-C18 alkyl petroleum sodium sulfonate; 5-10% of sorbitan fatty acid ester; and 3-10% of sodium abietate. The invention further discloses a preparation method and application of the combined collecting agent. The combined collecting agent is better in dispersity and selectivity, stable in agent property, free of sticky foam, easy to dissipate and resistant to low temperature, and normal-temperature flotation can be achieved. The method is simple in preparation process, easy to operate and low in cost.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and relates to a combined collector used for sorting low-grade fluorite ore; the invention also relates to the combined collector and its application. Background technique: [0002] Fluorite is a strategic mineral resource and the main raw material for producing fluorine-containing compounds. It is not only widely used in metallurgy, chemical industry, ceramics, building materials, machinery, electrical machinery, aviation, agriculture, medicine, precision instruments and other industrial sectors, but also is a Important high-energy materials for cutting-edge science and emerging industries such as atomic energy, rockets, and aerospace. At present, with the rapid development of fluorocarbons, fluoropolymers and fluorine-containing fine chemicals in the world, the international market is facing a serious shortage of fluorite fine powder. Fluorite has become a very important resource. Th...
