Embodiment 1

[0070] A mineral processing method provided by the present invention, in this embodiment, a gold mine in Xinjiang is used as the raw ore for mineral processing. In this test, the flotation collector Y89-0 solution is magnetized, and after treatment, flotation is carried out according to the conventional flotation process. . The whole process is at room temperature around 15-20°C, and the flotation concentration is 33%; using XFD laboratory 3L flotation machine and XMB-Φ200×240 rod mill mill, cylindrical magnetic rod (magnetic field strength: 0Oe, 6000Oe, 12000Oe ).

[0071] In order to compare with the flotation data without magnetization, so as to select the most suitable magnetic field strength, the magnetic field strength of 0 Oe is also selected as a comparative example in this embodiment for comparison.

[0072] Among them, the flotation concentration refers to the mass fraction of the amount of added dry ore in the total pulp amount.

[0073] The specific steps are:

Embodiment 2

[0090] In the mineral processing method provided by the present invention, in this embodiment, Korean scheelite is used as raw ore for mineral processing. In this experiment, the flotation collector saponified oleic acid solution was magnetized, and after treatment, flotation was carried out according to the conventional flotation process. Adopt XFD laboratory 3L flotation machine and XMB-Φ200×240 rod mill mill, cylindrical magnetic rod (magnetic field strength: 0000Oe, 6000Oe, 12000Oe).

[0091] In order to compare with the flotation data without magnetization, so as to select the most suitable magnetic field strength, the magnetic field strength of 0 Oe is also selected as a comparative example in this embodiment for comparison.

[0092] The specific steps are:

[0093] Ore processing: the ore is crushed by crushing equipment to a particle size of 2 mm to reach 100%, and then the ore is ground by a grinding machine until the weight of the ore below 200 mesh (ie 0.074mm) is ...

Embodiment 3

[0112] In the mineral processing method provided by the present invention, in this embodiment, Korean scheelite is used as raw ore for mineral processing. In this experiment, the ground scheelite raw ore pulp was magnetized, and after treatment, flotation was carried out according to the conventional flotation process. The whole process is at room temperature around 15-20°C, and the flotation concentration is 33%; using XFD laboratory 3L flotation machine and XMB-Φ200×240 rod mill mill, cylindrical magnetic rod (magnetic field strength: 0Oe, 6000Oe, 8000Oe , 10000Oe,).

[0113] In order to compare with the flotation data without magnetization, so as to select the most suitable magnetic field strength, the magnetic field strength of 0 Oe is also selected as a comparative example in this embodiment for comparison.

[0114] The specific steps are:

[0115] Ore processing: the ore is crushed by crushing equipment to a particle size of 2 mm to reach 100%, and then the ore is grou...

Abstract

The invention discloses an ore beneficiation method-magnetization flotation. This application mainly includes three magnetized flotation methods, namely collector magnetized flotation, pulp magnetized flotation and collector and pulp magnetized flotation simultaneously. Ore grinding: the raw ore is crushed by crushing equipment and then ground to obtain raw ore pulp; pulp magnetization treatment: the raw ore pulp after grinding is magnetized and stirred by a magnetic rod to obtain magnetized pulp; flotation pretreatment: the ore is ground The final raw ore slurry is poured into the flotation equipment for pH adjustment, inhibitor treatment and activation treatment in sequence; collector magnetization treatment: use a magnetic bar to magnetize and stir the prepared collector solution to obtain a magnetized collector; Foaming treatment: adding a foaming agent to the slurry treated with a magnetized collector and stirring; flotation: generating mineralized foam by aeration to float to the upper layer of the slurry surface of the flotation machine, and scraping the mineralized foam out of the obtained product through a scraper Concentrate; the rest is tailings.

Description

technical field [0001] The invention belongs to the technical field of mineral flotation, and in particular relates to an ore dressing method. Background technique [0002] Flotation is one of the most widely used mineral processing methods in the field of mineral processing. With the continuous exploitation and utilization of mineral resources, the mineral resources of all countries in the world have become poor, fine and miscellaneous, and the comprehensive recycling rate of mineral products is increasing. Low. Flotation is based on the difference in physical and chemical properties of the surface of mineral particles. According to the difference in mineral buoyancy, the useful minerals in the ore are enriched by adding flotation agents (regulators, inhibitors, activators, collectors, foaming agents, etc.). Another method of collection selection. The flotation operation is carried out in a three-phase system of gas, liquid and solid. Any change in the nature of any of t...
