Xikuangshan Mine is one of the major tin ore production bases in China and one of the earliest tin ore mining areas in the world. Antimony ore is an important ore in tin ore mountain, with high content, but its beneficiation is also difficult. In tin ore mountain, the beneficiation flow chart of antimony ore is very important, which can guide beneficiation engineers to conduct beneficiation operations and improve beneficiation efficiency. This paper will introduce the beneficiation flow chart and operation steps of Xikuangshan Mine antimony ore.
1、 Beneficiation Flow Chart of Xikuangshan Mine Antimony Ore
The beneficiation flow chart of Xikuangshan Mine antimony ore mainly includes the following steps:
1. Rough selection: Conduct preliminary physical separation of antimony ore, remove impurities and non-metallic minerals such as quartz, and obtain rough antimony ore.
2. Cleaning: further physical separation of coarse antimony ore to remove impurities such as Iron(III) sulfide and Copper monosulfide to obtain relatively pure antimony concentrate.
3. Flotation: The antimony concentrate is subjected to flotation, and the antimony ore is separated from the waste rock through the action of a flotation agent to obtain the antimony concentrate.
4. Sintering: Sintering antimony concentrate to convert it into antimony oxide and improve the purity of antimony.
5. Refining: Refining antimony oxide to remove impurities and other metal elements, obtaining high-purity antimony.
2、 Operating Steps
1. Steps for rough selection
(1) Send antimony ore into a crusher for crushing to obtain coarse ore.
(2) Feed the coarse ore into a vibrating screen for screening, removing impurities and non-metallic minerals such as quartz.
(3) The screened ore is sent to the gravity separator for gravity separation, and impurities such as Iron(III) sulfide and Copper monosulfide are removed to obtain coarse antimony ore.
2. Selected operation steps
(1) Feed the coarse antimony ore into the mill for grinding.
(2) The finely ground ore is fed into a flotation machine for flotation, and the antimony ore is separated from the waste rock through the action of a flotation agent to obtain antimony concentrate.
3. Flotation operation steps
(1) Feed antimony concentrate into a flotation machine and add flotation agents.
(2) By mechanical stirring and the action of bubbles, antimony concentrate floats on the liquid surface, while waste rocks settle below the liquid surface.
(3) Collect the antimony concentrate floating on the liquid surface to obtain the antimony concentrate.
4. Sintering operation steps
(1) Feed antimony concentrate into the sintering furnace.
(2) At high temperatures, antimony concentrate is converted into antimony oxide.
5. Refining operation steps
(1) Feed antimony oxide into the refining furnace.
(2) At high temperatures, a reducing agent is added to reduce antimony oxide to antimony.
(3) Through multiple refinements, impurities and other metal elements are removed to obtain high-purity antimony.
The beneficiation flow chart of Xikuangshan Mine antimony ore is a very important guiding tool in the antimony ore beneficiation process, which can guide the beneficiation engineers to conduct beneficiation operations and improve the beneficiation efficiency. The beneficiation flow chart of Xikuangshan Mine antimony ore includes such steps as roughing, concentration, flotation, sintering and refining. Each step has its own specific operating steps. The beneficiation engineer needs to operate according to the flow chart and operating steps to obtain high-purity antimony.Beneficiation Flow Chart of Xikuangshan Mine Antimony Ore
