Embodiment 1

[0028] like figure 1 , 2 , 3, the present embodiment is three kinds of mineralization mode parallel flotation implementation mode, including using countercurrent, swirling flow and jet flow three kinds of mineralization modes in combination in parallel mode, three kinds of mineralization modes are all based on flotation column Core construction, equipped with slurry mixing equipment, chemical system, feed pump, medium ore circulation pump, foam flushing water pump, liquid level control pump, liquid flow meter, gas flow meter; unit flotation is used when the three mineralization methods are used in parallel method.

[0029]The underflow pipe of the slurry mixing equipment 101 in the countercurrent mineralization system is connected to the feed port of the countercurrent flotation column 107 through a valve and a feed pump 102, and the underflow pipe of the countercurrent flotation column 107 passes through a valve, a middling ore circulation pump 103, The liquid flow meter 10...

Embodiment 2

[0038] In this embodiment, two or three mineralization methods can be selected in series to arrange and combine for testing. Since there are many test schemes, the combination of countercurrent + swirl + jet will be used as an example to illustrate the combination structure and test method of the experimental system, such as Figure 4 shown.

[0039] The structure of the test system is as follows:

[0040] The combined system is constructed with the flotation column as the core, equipped with slurry mixing equipment, chemical system, feed pump, medium ore circulation pump, foam flushing water pump, liquid level control pump, liquid flow meter, gas flow meter; three kinds of mineralization The continuous flotation method is adopted when the method is combined in series; it includes the first pulping equipment 1, the first feeding pump 1-1, the first liquid flow meter 1-2, and the countercurrent flotation column 1- 3. The first tailings pump 1-6, the second slurry mixing equipm...

Abstract

The invention discloses a combined type column floating selection system and belongs to the technical field of mineral floating selection. The system comprises three mineralization manners including adverse flow, rotational flow and jetting flow; the three mineralization manners can be independently used in parallel aiming at the diversity of mineral types and the complicated variability of physical characteristics, and two or three mineralization manners are combined in series to be used. When the three mineralization manners are used in parallel, a unit floating selection testing method is adopted, and a continuous floating selection testing method is adopted when the three mineralization manners are combined in series to be used; air bubbles in an adverse flow floating selection process are generated by feeding micro-pore ceramic through an air compressor; in the rotational flow and jetting flow processes, the air bubbles are generated by a self-suction type micro-bubble generator; mineral pulp, foam washing water and medicaments in the floating selection system are automatically fed through a pump and the floating selection system is measureable and adjustable. According to the combined type column floating selection system, a plurality of sorting manners are selected according to free combination of mineral physical characteristics, and the economic values of minerals are expressed to the greatest extent. The combined type column floating selection system has a simple structure, is convenient to operate and easy to control, has good reliability and low operation cost.

Description

technical field [0001] The invention belongs to the technical field of mineral flotation, relates to a flotation system, in particular to a combined column flotation system. Background technique [0002] Flotation columns are effective equipment for fine-grained mineral separation. The power source of the traditional flotation column (counter-current flotation column) is an external aeration system. Since there is no medium ore recovery process, the method of increasing the aeration volume and increasing the height of the column is usually used to improve the flotation effect. This type of flotation column has shown certain advantages in dealing with low-yield metal ore or non-metal ores, but its advantages are often not so obvious when separating materials with high yield (such as coal slime). With the large-scale development of mineral resources, the particle size of the selected ore is getting finer and lower, and the grade is getting lower and lower. Multi-force field a...
