Problems solved by technology

Some antimony sulfide ore deposits with a large proportion of antimony oxide minerals use gravity separation methods such as shaking table and screw slide to recover antimony oxide minerals after flotation of antimony sulfide minerals. However, the recovery effect of this method is not obvious, making antimony oxide minerals resource loss

Embodiment 1

[0026] An example of the sulfur-oxygen symbiosis mixed antimony ore flotation recovery method of the present invention comprises the following steps and medicament system:

[0027] 1. Mineral raw materials:

[0028] The material used is sulfur-oxygen symbiotic mixed antimony ore, and the antimony content in the ore is 1.59%. The phase analysis of antimony shows that the antimony minerals are mainly stibnite, and also contain some antimonite, stibnite and a small amount of stibnite. Among them, the proportion of stibnite is 74.24%, antimonite is 14.45%, stibnite is 5.11%, yellow antimonite is 2.65%, and other antimony minerals are 3.55%.

[0029] 2. Flotation agents and operating conditions:

[0030]

[0031] During the flotation process, the sulfur-oxygen symbiotic mixed antimony ore is ground until the mineral monomers are dissociated, and then sodium hexametaphosphate is added as a mineral dispersant, potassium permanganate is used as a mineral oxidant, sodium sulfide i...

Abstract

The invention discloses a sulfur-oxygen symbiotic mixed antimony ore flotation recovery method which includes the steps and reagent systems: taking sodium hexametaphosphate as a mineral dispersing agent; taking potassium permanganate as a mineral oxidant; taking sodium sulfide as a mineral vulcanizing agent; taking copper sulfate as a mineral activating agent; taking butyl xanthate as a mineral collecting agent; taking 2# oil as a foaming agent; collecting sulfur-oxygen symbiotic mixed antimony to obtain antimony concentrate. Sulfur-oxygen symbiotic mixed antimony ores can be effectively recovered, and the antimony concentrate with 48.72%-51.30% antimony grade and 87.21%-90.53% recovery rate can be obtained under the condition of 1.59%-2.56% antimony grade and 21.34%-25.76% antimony oxidation rate of feed ore.

Description

[0001] 1. Technical field [0002] The invention relates to a flotation recovery method of a sulfur-oxygen symbiotic mixed antimony ore, in particular to a flotation recovery method of a sulfur-oxygen symbiotic mixed antimony ore with a large proportion of antimony oxide. [0003] 2. Background technology [0004] In some antimony sulfide deposits, some antimony oxide minerals are often associated with them. For antimony sulfide deposits with a small proportion of antimony oxide minerals, flotation is generally used to recover antimony sulfide minerals and the antimony oxide minerals are discarded in tailings ponds. Some antimony sulfide ore deposits with a large proportion of antimony oxide minerals use gravity separation methods such as shaking table and screw slide to recover antimony oxide minerals after flotation of antimony sulfide minerals. However, the recovery effect of this method is not obvious, making antimony oxide minerals Resource loss. With the gradual reductio...
