[0002] Antimony oxide ore accounts for about 15% of the total proven antimony reserves in my country. The traditional ore dressing of antimony oxide ore generally adopts the gravity separation method. 12%, resulting in a serious waste of resources
However, due to the low hardness of antimony oxide minerals, it is easy to crush and muddy when crushed, and the zero-electric point of antimony oxide minerals is almost the same as that of quartz, so that the flotation behavior of the two is very similar. At the same time, antimony oxide minerals will be hydrolyzed into trace The hydrophilic surface compound HSbO 2 or HSbO 3 , thus, it is difficult to recover antimony oxide ore by flotation

Embodiment 1

[0048] In a certain antimony mine in Hunan, the antimony oxide ore contains 1.10wt% Sb (mainly yellow antimony ore and antimonite). First, the antimony oxide ore is mixed with water, and then the mixed material is sent to a ball mill for ball milling. The ore washing machine washes the materials after ball milling to obtain antimony oxide slurry with a particle size of no more than 0.074 mm and a mass concentration of 20-70 wt %, and antimony oxide slurry with a particle size of no more than 10 microns. Then mix the lead nitrate and antimony oxide pulp according to the mass ratio of 4:10000 in the state of stirring, and stir for 2-6min to obtain the activated pulp; then combine the collector RCOOM, the foaming agent methyl isobutyl carbinol and the activated The ore pulp is mixed and stirred according to the mass ratio of 40:5:100000, and stirred for 2-6 minutes to obtain a mixed liquid with a pH value of 6.0-10.0, and then the mixed liquid is subjected to flotation for 3-10 mi...

Embodiment 2

[0050] In a certain antimony mine in Guangxi, the antimony oxide ore contains 1.30wt% Sb (mainly yellow antimonite and antimonite). The antimony oxide ore is mixed with water first, and then the mixed material is sent to a ball mill for ball milling, and finally the antimony oxide ore is mixed with water. The ore washing machine washes the materials after ball milling to obtain antimony oxide slurry with a particle size of no more than 0.074 mm and a mass concentration of 20-70 wt %, and antimony oxide slurry with a particle size of no more than 10 microns. Then mix the lead nitrate and antimony oxide pulp according to the mass ratio of 3:10000 in the state of stirring, and stir for 2-6min to obtain the activated pulp; then combine the collector RCOOM, the foaming agent methyl isobutyl carbinol and the activated The pulp is mixed and stirred according to the mass ratio of 60:4:100000, and stirred for 2-6 minutes to obtain a mixed liquid with a pH value of 6.0-10.0, and then the...

Abstract

The invention discloses a method for treating antimony oxide ore. The method comprises the steps that (1), the antimony oxide ore is pretreated, so that antimony oxide ore pulp and fine mud are obtained; (2), an activator is mixed with the antimony oxide ore pulp, and activated ore pulp is obtained; (3), a collecting agent, a foaming agent and the activated ore pulp are mixed, and the flotation treatment is conducted, so that antimony rough concentrate and tailings are obtained; and (4), concentration treatment is conducted on the antimony rough concentrate, and antimony concentrate is obtained. According to the method, a beneficiation reagent is low in cost, the regime of the agent is simple, the index is stable, meanwhile the recovery rate of the antimony concentrate is increased by over 42%, and the economical benefits are remarkable.

Description

technical field [0001] The invention belongs to the field of mineral processing of antimony oxide ore, in particular, the invention relates to a method for processing antimony oxide ore. Background technique [0002] Antimony oxide ore accounts for about 15% of the total proven antimony reserves in my country. The traditional ore dressing of antimony oxide ore generally adopts the gravity separation method. 12%, resulting in a serious waste of resources. However, due to the low hardness of antimony oxide minerals, it is easy to crush and muddy when crushed, and the zero-electric point of antimony oxide minerals is almost the same as that of quartz, so that the flotation behavior of the two is very similar. At the same time, antimony oxide minerals will be hydrolyzed into trace The hydrophilic surface compound HSbO 2 or HSbO 3 , Thus, antimony oxide ore is difficult to recover by flotation method. [0003] Therefore, the existing technology for processing antimony oxide or...
