Problems solved by technology

Some collectors are compounded with rubber oil and plastic oil. This kind of collector has a very unstable odor.
With the tight supply of coal resources in recent years, a lot of mining has led to the extraction of a lot of tender coal (relatively young coal). The proportion of these coals is large, which has brought great difficulties in coal washing. General collectors It can't be captured

Embodiment Construction

[0022] A GH coal collector, the components and content of the collector are 3-12% of mixed surfactant, 1-5% of co-solvent, 3-8% of common kerosene, 5-17% of 0# national standard diesel oil, 45-60% deionized water.

[0023] Further preferably, the main components of the mixed surfactant are coconut oil fatty acid diethanolamide, sodium petroleum sulfonate, and oleic acid. The surface active agent that is beneficial to change the surface properties of coal is compounded, and the surface properties of coal with a low degree of metamorphism are converted to lipophilicity, so that the surface of hydrophilic coal becomes the surface of hydrophobic coal. At the same time, the surfactant also has rapid dispersion in the coal slurry, which greatly increases the chance of contact between oil droplets and coal particles.

[0024] Further preferably, the co-solvent is a mixture of n-butanol, 2-ethylhexanol and n-octanol.

[0025] Further preferably, the deionized water is soft water wit...

Abstract

The invention discloses a GH coal collector and a preparation method thereof, and the collector comprises the following components by weight percent: 3-12% of mixed surfactant, 1-5% of cosolvent, 3-8% of ordinary kerosene, 5-17% of No.0 national standard diesel oil and 45-60% of deionized water. The preparation method comprises the following steps: adding 3-12% of the mixed surfactant and 1-5% of the cosolvent into 5-17% of the No.0 national standard diesel oil and 3-8% of the ordinary kerosene at the temperature of 40-65 DEG C and the normal pressure, stirring for 10 minutes, then adding 45-60% of the deionized water, cooling and performing high-speed shearing and stirring for 0.5 hour. The cost is low, the process is simple and the operation is convenient. The GH coal collector and the preparation method thereof are widely suitable for the field of mineral processing engineering.

Description

technical field [0001] The invention belongs to the field of mineral processing engineering, and relates to a medicament for beneficiation and a preparation method thereof, in particular to a GH coal collector and a preparation method thereof. Background technique [0002] With the shortage of coal resources in my country and the strict control of the country in recent years, a large amount of raw coal has to be washed, and the messy quality of coal has made it more difficult for the flotation process and the recovery of clean coal, which has seriously affected to the economic benefits of the coal preparation plant. These problems have prompted the continuous birth of new flotation agents, and collectors are used in the coal purification flotation process to enhance the surface hydrophobicity of coal particles, promote the adhesion of air bubbles between coal particles, and improve the fixation strength of coal particles on air bubbles. leading role. At present, the collect...
