Embodiment 1

[0044] The mineral samples provided by the JKMRC Mining Laboratory in Brisbane, Australia are used as the original ore. The ore sample is a disseminated skarn copper ore. According to the results of multi-element analysis, the main useful minerals are chalcopyrite, pyrite, bornite and chalcocite; gangues include silicate minerals such as quartz, pyridine, sericite, chlorite, etc. Carbonate minerals such as dolomite and calcite. The ore also contains a small amount of clay minerals, which are easy to muddy. The chalcopyrite embedding particle size is 0.0006-0.05mm. About 20% of chalcopyrite is distributed in gangue minerals or pyrite in the form of 10-20 μm. The ore belongs to refractory ore.

[0045] The experiment uses a flotation column with a height of 3.5 meters and a diameter of 10 centimeters, and the bubble generator is a 5 μm porous metal bubbler. The flotation test is a continuous test, the mixed flotation collector of sulfide ore is ethyl xanthate, and the pH re...

Embodiment 2

[0050] The sample coal provided by Elk Valley Coal (EVC) in BC, Canada was used as the raw coal. The coal quality is fat coal, moderately buoyant, easy to slime, containing 24.67% ash, 68.77% carbon, and 1.17% sulfur. Mineral components in ash include quartz, clay minerals, pyrite and a small amount of carbonate minerals. In terms of particle size, the ash content is mainly concentrated between -0.1mm fine particle size and +1mm coarse size particle size.

[0051] The experiment uses a flotation column with a height of 3.5 meters and a diameter of 10 centimeters, and the bubble generator is a 5 μm porous metal bubbler. The flotation test is a continuous test, and the coal has good floatability and hydrophobicity, and no collector and regulator need to be added. The pH value was maintained at about 7.1 during the test. The inflation rate of the flotation column is 0.5cm / s, the ore feeding rate is 1200mL / min, and the height of the foam layer is set to 5cm. The selected parti...

Abstract

The invention specifically relates to a combinatorial method for surfactant composition, namely, foaming agent with high selectivity and high foaming characteristics. The combinatorial method is characterized in that.

Description

technical field [0001] The invention belongs to the field of mineral processing and relates to a combination method of foaming agent-surfactant composition. Background technique [0002] Froth flotation achieves separation through the different effects of the surface properties of different minerals on the liquid and gas in the pulp. Among them, the air bubble is the carrier, and the mineral particles are the carrier. Obtaining stable air bubbles through one of the flotation reagents, that is, the foaming agent, is the prerequisite for efficient flotation. The processing capacity and economic indicators of the flotation machine or flotation column are directly related to the hydrodynamic parameters in the collection area, such as aeration rate, at best, bubble size and distribution, and the foam layer thickness or water recovery in the selection area. relation. Although the above parameters are related to the physical characteristics of the flotation equipment, such as th...
