Problems solved by technology

These desliming methods have certain disadvantages: mechanical desliming needs to dilute the pulp to a concentration of less than 10%, wasting a lot of water resources, and desliming is not complete, and often requires repeated desliming; traditional foaming agents have Pungent odor, low desliming efficiency, a small part of fine-grained spodumene minerals will enter the foam product, resulting in a large loss of lithium

Embodiment 1

[0021] Li contained in a spodumene mine in Sichuan 2 The O grade is 1.38%, the solid mass concentration of the ore pulp transferred into the flotation machine after grinding is 27%, and the content of -0.074mm particle size accounts for 60%. Add 1000 g / t of sodium carbonate, stir for 5 minutes and then add 60 g / t amount of mixed collector. The mixed collector is made by mixing sodium lauryl sulfate and 2-hexanol in a mass ratio of 80:20. Aerated flotation was carried out after stirring for 5 minutes. After 6 minutes of flotation, the foam product and the product in the tank were respectively filtered, dried, weighed, and tested to obtain the index data for flotation desliming of spodumene by this method, and compared with traditional sedimentation desliming and foaming The data are shown in the table below for comparison.

Abstract

The invention discloses a reverse flotation and desliming method for a triphane ore. The reverse flotation and desliming method for the triphane ore comprises the steps that firstly after suitable sodium carbonate is added into finely ground triphane ore pulp for sufficient stirring, a mixed collecting agent composed of sodium alkyl sulfate and fatty alcohol is added, and flotation and desliming are carried out after sufficient stirring. According to the reverse flotation and desliming method for the triphane ore, the sodium carbonate acts as a pH regulator and a slurry dispersing agent; and the mixed collecting agent has a selective collecting effect on fine fraction stage gangue minerals, and has high foaming performance. Under the cooperative effect of medicaments, air sucked into a flotation machine forms a large amount of fine bubbles with higher surface free energy in the ore pulp, and the bubbles can adsorb the fine fraction stage gangue minerals to the bubble surface to form solid-liquid-gas three-phase foam in the rising process. Slurry products can be obtained by scraping the upper layer foam, and inner groove products are triphane rough concentrate after desliming. The reverse flotation and desliming method for the triphane ore has the advantages of simple process, short processing time, sufficient desliming, and capable of obviously improving the operating effect ofsubsequent triphane flotation.

Description

technical field [0001] The invention relates to a spodumene ore reverse flotation desliming method, which belongs to the technical field of mineral processing engineering. Background technique [0002] Lithium is known as "the new energy metal of the century" and "an important element that drives the world forward". It is an important rare metal. Lithium and its compounds can be used as heat carriers for nuclear reactors, protective materials for thermal neutrons, and moderators. As well as nuclear fuel solvents, high-energy fuels, and can also be used to produce high-performance lubricants, high-power battery materials, etc. There are two main sources of lithium: one is salt lake brine lithium; the other is ore lithium, and spodumene ore is a typical representative of ore lithium. [0003] Spodumene ore is generally exposed on the surface and is easily affected by weathering. Therefore, spodumene ore is particularly prone to muddying. The finely ground spodumene slurry con...
