Embodiment 1

[0059] In order to verify the sorting effect in each component when the formula 1 compound in the medicament A of the present invention is used alone, we adopt galena and sphalerite (original grade as shown in Table 1) in Hunan, using figure 1 The process shown in the experiment is divided into two groups, and the compound of formula 1 in this case is used alone as the flotation agent for flotation of galena and sphalerite. The flotation parameters of each group are the same, and the only difference is that the types of minerals are different, so that Compare the flotation and sorting effects of the compound of formula 1 in this case.

[0060] Flotation agent in this case: 95 parts of the compound of formula 1 (see Table 2), 5 parts of 2# oil.

[0061] The specific operation is: Dry grind 500g of concentrate ore (galena or sphalerite; particle size 3mm~0.5mm) for 15 minutes (the particle size after grinding is 0.0374~0.074mm, use a horizontal ball mill to dry grind, grind ore ...

Embodiment 2

[0067] In order to verify the sorting effect in each component when the compound of formula 1 in the medicament A of the present invention is used in combination, we adopt galena and sphalerite (original grade as shown in Table 1) in Hunan, using figure 1 The flow shown in the experiment is divided into two groups, and the compound of formula 1 in this case is used as the flotation agent to carry out flotation of galena and sphalerite. The flotation parameters of each group are the same, and the only difference is that the types of minerals are different, so that Comparing the flotation and sorting effects of the combined collector of the compound of formula 1 in this case

[0068] Flotation reagents in this case: a total of 95 parts of the compound of formula 1, and 5 parts of 2# oil.

[0069] The specific operation is: Dry grind the concentrate ore (galena or sphalerite, with a particle size of 3 mm to 0.5 mm) for 15 minutes (the particle size after grinding is 0.0374 to 0.0...

Embodiment 3

[0076] In this case, in order to verify the impact of the compound of formula 2 in the combined drug agent B on the recovery rate in flotation, we use galena and sphalerite in Hunan (the original grade is shown in Table 1). figure 1 In the process shown, the experiment is divided into two groups, and one of the compounds of formula 2 in this case and the compound of formula 1 (specifically 1-C + formula 1-D (mass ratio is 1:1)) are combined as the flotation agent counterpart The flotation of lead ore and sphalerite, the flotation parameters of each group of cases are the same, the only difference is that the types of minerals are different, so as to compare the impact of the compound of formula 2 in the combined drug on the recovery rate in flotation.

[0077] Flotation reagents in this case: 10 parts of the compound of formula 1, 85 parts of the compound of formula 2, and 5 parts of 2# oil.

[0078] The specific operation is: Dry grind the concentrate ore (with a particle siz...

Abstract

The invention belongs to the field of mineral flotation, and in particular relates to a flotation reagent for selectively separating galena and sphalerite and an application method thereof. Cooperating with agent B, it helps to further selectively capture galena and suppress sphalerite, so as to realize the selective separation of the two, not only that, but also improve the recovery rate and grade of galena.

Description

technical field [0001] The invention belongs to the field of mineral flotation, in particular to a selective flotation separation technology for mixed ore of lead sulfide and sphalerite. Background technique [0002] my country's lead resource mines are relatively rich, but the types of ores are complex, often associated with a variety of minerals, with the characteristics of more lean ore and less rich ore. Galena is an important source of lead, and sphalerite is its common associated mineral. Because the surface properties are similar, the flotation separation of the two is difficult, which affects the flotation index. Therefore, it is of great significance to improve the selectivity and efficiency of flotation agents for lead-zinc sulfide ore. [0003] The most effective and commonly used method for the separation and utilization of lead-zinc sulfide ore at this stage is through flotation. Flotation agents are an important part of flotation, and the development of new f...
