experiment example

[0027] Experimental example: Separation of copper sulfide and molybdenum sulfide in a copper-molybdenum mine in Tibet

[0028] Since the flotation separation of polymetallic sulfides involves the separation of different metal sulfides, the inhibitors used are different according to the type of ore and the characteristics of the ore;

[0029] The mine beneficiation processes copper-molybdenum ore. The technological process is: mixed flotation-copper-molybdenum separation. Mine, the present invention is applied in the fifth selection process of depressant addition;

[0030] The foam of each flotation operation enters the next operation in sequence, and the tailings return in sequence;

[0031] The types of conventional dosing process inhibitors are: sodium hydrosulfide, dosage (total amount):

[0032] The dosing process inhibitor kind of the present invention is: sodium hydrosulfide, consumption (total amount):

[0033] Other selected operations are added according to the...

Abstract

The invention relates to a targeted dosing method in the process of sulfide ore flotation polymetallic separation, which belongs to the method of adding inhibitors in the process of sulfide ore flotation polymetallic separation. The selected foam enters the vertical spiral agitating mill for scrubbing and grinding, and the inhibitor adding pipeline is surrounded by multiple clean water flushing water pipelines, and the pipelines are combined with water outlets and chemical outlets, and go down to the pulp of the vertical spiral agitating mill Below the surface and above the steel ball interface; the pipeline group is connected to the clean water flushing water and the inhibitor is fed into the vertical spiral stirring mill at the same time to ensure the pressure of the clean water. The advantages are: the effect of the inhibitor is enhanced, and the dosage of the inhibitor is reduced, which not only saves the production cost, but also reduces the amount of residual inhibitor in the backwater, makes the return of the backwater more flexible, and eliminates the impact on the front-end mixing flotation.

Description

technical field [0001] The invention relates to a method for adding inhibitors in the sulfide ore flotation polymetallic separation process. Background technique [0002] Sulphide ore flotation multi-metal separation, through the addition of inhibitors to change the physical and chemical properties of one or several mineral surfaces, change the hydrophobicity of the mineral surface, so that the minerals that need to be suppressed remain in the slurry system, and the minerals that need to float on the surface The physical and chemical properties do not change, and the original surface hydrophobicity does not change, and it floats into the foam, thereby realizing the separation of two or more metal sulfides. [0003] At present, there are mainly two schemes for the separation of multiple metals in beneficiation flotation: ① Inhibit one or more metals from floating up to one metal. ② Inhibit one or more metals from floating one or more metals. No matter what method is used, i...
