Problems solved by technology

All four agents can change the surface structure of antimony oxide ore and activate antimony oxide ore, but they have no effect on quartz
[0009] The activator used in the process of recovering antimony oxide ore by flotation is mainly lead salt, and the commonly used one is lead nitrate. To realize the full activation of antimony minerals, a relatively large amount of lead nitrate needs to be added, which will cause a part of Pb to enter the antimony In the concentrate, when the content of Pb in the antimony concentrate is greater than 0.15%, it will affect the smelting process of antimony
[0010] Therefore, existing flotation regulators and antimony oxide ore flotation methods still need to be improved

Embodiment 1

[0048] The Sb 1.52% of the antimony ore, which mainly exists in the form of ruthenium and 华.

[0049] The ore and water were mixed with water to obtain a slurry, and the milling fineness of -0.074 mm accounted for 80%, and the slurry concentration was 30%. Add a composite adjustment agent to the slurry, first add inhibitors, inhibitors including water glass and sulfuric acid with a mass ratio of 2.5: 1, and the amount of activator is added, and the activator includes a mass ratio of 1: 2 The lead and copper sulfate of copper sulfate were used at 900 g / t, stirred for 3 min. The addition of dodylamine is added to the slurry as a catch agent, and the amount of amount of 200 g / t, pneisal alcohol oil is a foaming agent, and the amount is 120 g / t, the catching agent, and the foaming agent are added to stir for 2 min. After a two-selection of secondary selection of secondary selection, the antimony concentration was finally obtained.

Embodiment 2

[0052] Example 2 is the same as that of the first embodiment, and the inhibitor includes a mass ratio of 2: 1 in the composite adjuster. Water glass and sulfuric acid.

[0053] In the cerium oxide concentrate obtained in this example, the antimony product is 27.46%, the recovery is 85.94%, and the PB content is 0.067%, and there is no more than 0.15% of the national standard PB content.

Embodiment 3

[0055] Example 3 Similarly to the method of the first embodiment, the inhibitors in the composite regulator include water glass and sulfuric acid having a mass ratio of 3: 1.

[0056] In the cerium oxide concentrate obtained in this example, the antimony product was 28.67%, the recovery rate was 83.46%, the PB content was 0.071%, and there was no more than the national standard PB content of 0.15%.

Abstract

The invention discloses an inhibitor for flotation of antimony oxide ore, which comprises water glass and sulfuric acid or hydrochloric acid in a mass ratio of (2-3): 1. The invention further discloses a composite regulator for flotation of antimony oxide ore. The composite regulator comprises the inhibitor and an activating agent, the activating agent comprises lead nitrate and copper sulfate, and the mass ratio of the lead nitrate to the copper sulfate is 1: (1-3). The composite regulator is simple in composition and low in cost and makes a flotation reagent system simple and stable in indexes, the composite regulator is suitable for the antimony oxide ore which is seriously flocculated and argillized and difficult to select, gangue minerals are inhibited, meanwhile, the antimony oxide ore can be activated, and the grade and the recovery rate of antimony oxide concentrate are improved.

Description

Technical field [0001] The present invention belongs to the field of cerium oxide mineral selection, and in particular, the present invention relates to an inhibitor for a flotation of a cerium oxide, and further includes a composite modifier for a flotation of antimony oxide deposits, in particular. It also relates to a flotation method for cerium oxide mine. Background technique [0002] The surface wettability of the antimony oxide mine is large, and thus the floreability is extremely poor, and it is difficult to flot. [0003] Therefore, the method of treating antimony mine in domestic and foreign production practices is still based on reselection, but since the stimbium oxide mine is low, it is easy to muddy during the grinding process, and the produced fine agtiogenlium oxide can lead to reselection. The job recovery rate is lowered, and the problem of full recycling of antimony hydrazine ore resources cannot be solved. The reselection of the recovery rate is low, and only ...
