Embodiment 1

[0013] Embodiment 1: take by weighing pectin, cetyltrimethylammonium bromide and methyl isobutyl carbinol and emulsifier according to the mass ratio of 1:7:1:1, wherein water and emulsifier according to 1 : 1 ratio for preparation, mixed according to the following steps:

[0014] Step 1: put sorbitan trioleate and water in a mixing tank according to a certain mass ratio, stir at a high speed of >5000r / min for 30min, and initially obtain an emulsion of sorbitan trioleate;

[0015] Step 2: Place the ultrasonic probe about 2-3cm below the liquid surface, and turn on the ultrasonic equipment with a power of 540W and an ultrasonic time of 20 minutes. The oil droplets are dispersed into smaller micro-oil droplets under the action of ultrasonic;

[0016] Step 3: Heating the emulsion obtained in Step 2 by program heating, stirring slowly and keeping it at 100 degrees Celsius for 3 hours;

[0017] Step 4: Add pectin to the emulsion obtained in step 3 according to a certain mass ratio,...

Embodiment 2

[0025] Embodiment 2: according to 1:5:2:2, take gentamicin, cetyltrimethylammonium bromide and methyl isobutyl carbinol and emulsifier, according to the steps described in Example 1, prepare Foaming agent.

Embodiment 3

[0026] Embodiment 3: according to 1:5:1:3, take pectin, cetyltrimethylammonium bromide and methyl isobutyl carbinol and emulsifier, according to the steps described in Example 1, prepare Foaming agent.

Abstract

The invention discloses a positive ion type foaming agent for mineral separation. Cucurbitacin, cetyl trimethyl ammonium bromide, methyl isobutyl carbinol and an emulgator serve as raw materials, and by means of high-strength stirring, an appropriate matching ratio, ultrasonic treatment and other operation, the novel ion type foaming agent is obtained. The positive ion type foaming agent is especially suitable for flotation of micro-fine grained metal, in the flotation process, the novel foaming agent is scattered into ore pulp, after inflation is carried out, micro-foam with surface provided with positive charges is produced, the surfaces of metal mineral grains are provided with negative charges, the grains and the foam collide with each other through the intensifying action of electrostatic attraction, chitosan-sepiolite is added, finally, very efficient mineralization is achieved through the foam, and the recycling rate is greatly increased.

Description

technical field [0001] The invention relates to a cationic foaming agent for ore dressing, which belongs to the field of mineral flotation. Background technique [0002] With the rapid development of my country's economy, the market demand for metal minerals as primary raw materials is increasing. At the same time, with the large-scale popularization and application of mechanical mining technology, the silicate represented by silica in raw ore Mineral content is getting higher and higher. At the same time, after large-scale mining of high-quality resources, the content of low-grade complex and refractory minerals is getting higher and higher, which brings severe challenges to the existing mineral processing technology. [0003] At present, flotation is still one of the most effective means to deal with fine-grained and micro-sized ore particles. It utilizes the difference in surface hydrophobicity between target minerals and gangue minerals, and further strengthens the covera...
