Embodiment

[0018] The antimony raw ore is crushed and ground to a fineness of 63.8%-200 mesh, and 1530 g / ton of sulfuric acid is added to adjust the pH value to 6.1; 2 (SO 4 ) 3 830g / ton is antimony mineral activator, 85g / ton ethyl disulfide nitrogen, 119g / ton butylammonium black medicine, 50g / ton No. 25 black medicine are used as collectors, after being stirred and activated, enter the flotation machine Antimony ore flotation. Antimony concentrate products and tailings are obtained through primary roughing, secondary beneficiation, and three-time sweeping.

[0019] Flowchart such as figure 2 As shown, the results are shown in Table 1. The grade of the antimony concentrate reached 49.11%, the antimony recovery rate reached 90.34%, and the lead content in the antimony concentrate was only 0.066%, and the lead reduction effect was good.

Abstract

The invention provides an environment-friendly beneficiation method of antimonyore, which takes H2SO4 as ore pulp pH value conditioning agent and Al2(SO4)3 as antimonyore activator; the flotation effect which is the same as taking lead nitrate as the antimonyore activator can be obtained; the new medicament combination of butyl ammonium aerofloat, diethyldithiocarbamate and No. 25 black powder can be adopted, and the auxiliary agent is saved. The technical method is simple and free from pollution, can improve the surrounding environment of the place where antimonyore enterprises are positioned, and the beneficiation cost is greatly reduced. Antimony concentrate prepared by the beneficiation method has low lead content and high recovery rate, thus being a new way of environment-friendly antimony beneficiation.

Description

technical field [0001] The invention relates to the field of mineral processing, in particular to a mineral processing method of antimony ore. Background technique [0002] With the rapid development of global economic integration, the requirements of the national economy for non-ferrous metals are increasing day by day. Antimony is an important means of production in industrial production and people's life. Because antimony alloys have many excellent properties, they are widely used, such as battery plates, bearings, printing type, household alloys, cable sheaths at the bottom of pools, and military industries. Antimony compounds are also widely used in various industrial sectors. However, due to the use of lead nitrate in order to improve the buoyancy of antimony in the beneficiation process of antimony, the use of lead nitrate increases the content of lead in the antimony concentrate, and also increases the content of lead ions in the tailings water, resulting in the imp...
