Problems solved by technology

[0004] CN101623673A discloses a kind of beneficiation method of antimony ore, adopts H 2 SO 4 As a pH adjuster for pulp, and then use Al 2 (SO 4 ) 3 As an antimony mineral activator, the resulting antimony concentrate contains low lead, but the antimony recovery rate is only 90.34%, the recovery rate is low, and the H 2 SO 4 The addition of it has a corrosive effect on the equipment and has a certain impact on the safety of the operation
However, by flotation recovery of carbon-containing lead-zinc-antimony ore, the highest grade of antimony in the obtained lead-antimony concentrate is only 12.55%, and the highest antimony recovery rate is only 70.23%. high problem

Abstract

The invention relates to a mineral processing method of antimony sulfide ore. The mineral processing method comprises the following steps: crushing raw antimony sulfide ore, carrying out ore grinding, adding water, stirring, carrying out size mixing, recycling antimony sulfide minerals by adopting a flotation method, and carrying out roughing once, scavenging for three times and concentration for three times to obtain antimony concentrate, wherein lead nitrate is taken as an activating agent, xanthogenate mixture and B sulfur nitrogen are taken as a combined collecting agent and new coniferyl oil is taken as a foaming agent during the roughing, and the lead nitrate is taken as the activating agent and the xanthogenate mixture is taken as a collecting agent during primary scavenging and secondary scavenging. The method provided by the invention has the advantages that floatation collecting capability on the antimony sulfide minerals is strong, recycling effect is good, antimony recovery rate is more than or equal to 93.2% and is increased by 0.98% compared with the prior art, lead-antimony ratio in the antimony concentrate is reduced by more than or equal to 26.8%, and antimony concentrate grade is more than or equal to 50.0%; reaction conditions of the method provided by the invention are neutral, corrosive effect on mineral processing equipment is alleviated, operation safety is improved, and production cost is reduced; and the method provided by the invention is easy to operate, efficient and environmentally friendly.

Description

technical field [0001] The invention relates to a beneficiation method, in particular to a beneficiation method of antimony sulfide ore. Background technique [0002] Antimony and its compounds are widely used as important raw materials in industrial production and people's life. With the continuous mining of antimony metal mines, antimony resources are decreasing, and the grade of ore is getting lower and lower. Traditional conventional flotation reagents are used to And methods have been difficult to improve the mineral processing recovery. [0003] In order to improve the recovery rate of antimony in the process of antimony flotation, lead nitrate is used as antimony flotation activator, but some lead ions will enter the antimony concentrate, and lead is a harmful impurity in antimony concentrate, and antimony concentrate contains lead High will affect the grade of antimony concentrate, so as to affect the sales price. In addition, the antimony concentrate contains high...
