Embodiment 1

[0017] This embodiment 1 provides a method for separating copper-lead sulfide minerals, which uses the raw ore of copper-lead sulfide minerals as raw material, and performs preferential flotation separation on the raw ore of copper-lead sulfide minerals to obtain lead concentrate minerals. The method includes :

[0018] Using the raw ore of copper-lead sulfide minerals as raw material, the raw ore of copper-lead sulfide minerals is separated and roughed to obtain lead coarse concentrate minerals; during the process of separating and roughing the raw ore of copper-lead sulfide minerals, water-soluble thioglycolate or mercapto Acetic acid as an inhibitor of copper sulfide minerals in the separated ore;

[0019] Afterwards, the obtained lead coarse concentrate minerals are refined and separated to obtain lead concentrate minerals. In the process of refining lead concentrate minerals, water-soluble thioglycolate or thioglycolic acid is also added as Inhibitors of copper sulfide m...

Embodiment 2

[0028] This embodiment 2 provides a method for separating copper-lead sulfide minerals, which uses the raw ore of copper-lead sulfide minerals as raw material, and performs preferential flotation separation on the raw ore of copper-lead sulfide minerals to obtain lead concentrate minerals. The separation method that embodiment 1 provides is basically the same, and the difference is that in the flotation separation process to minerals, potassium thioglycolate is used as the inhibitor to copper sulfide minerals in the separated minerals, and the specific steps are as follows:

[0029] The raw ore grade of copper-lead ore is Cu 0.61%, Pb 11.23%. The raw ore is added to the flotation tank for copper-lead separation and roughing operation. During the separation and roughing process, potassium thioglycolate is added as the copper sulfide mineral in the separated minerals. Inhibitor, the amount of inhibitor added is 1000g / t, that is, 1000g inhibitor is added for each ton of separated ...

Embodiment 3

[0033] This embodiment 3 provides a method for separating copper-lead sulfide minerals, which uses the raw ore of copper-lead sulfide minerals as raw material, and performs preferential flotation separation on the raw ore of copper-lead sulfide minerals to obtain lead concentrate minerals. The separation method that embodiment 1 provides is basically the same, and the difference is that in the flotation separation process to minerals, ammonium thioglycolate is used as the inhibitor to copper sulfide minerals in the separated minerals, and the specific steps are as follows:

[0034]The copper-lead ore raw ore grade is Cu 0.55%, Pb 4.98%. The raw ore is added to the flotation tank for copper-lead separation and roughing operation. During the separation and roughing process, ammonium thioglycolate is added as the copper sulfide mineral in the separated minerals. Inhibitor, the amount of inhibitor added is 260g / t, that is, 260g of inhibitor is added for each ton of separated minera...

Abstract

The invention discloses a method for separating copper-lead sulfurized minerals, and belongs to the technical field of mineral dressing. The method takes raw ores of the copper-lead sulfurized minerals as a raw material, and comprises the following step: performing floatation separation on the raw ores of the copper-lead sulfurized minerals to obtain lead concentrate minerals or obtain the lead concentrate minerals and copper concentrate minerals, wherein water soluble thioglycolate or thioglycollic acid is added to serve as an inhibitor for the sulfur sulfurized minerals in the separated minerals. The water soluble thioglycolate or thioglycollic acid serving as the inhibitor for the copper sulfurized minerals has the advantages of good selectivity, strong inhibition capacity, low consumption, convenient addition and the like, so the water soluble thioglycolate or thioglycollic acid can well inhibit the sulfur sulfurized minerals to achieve better floatation effect; simultaneously, the method effectively overcomes the defects of rank poison, severe operating environment and heavy pollution of commonly used sodium (potassium) cyanide, and also has the characteristics of convenient addition, safe use and the like. The invention provides the method facilitating separating the copper-lead sulfurized minerals.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a method for separating copper-lead sulfide minerals. Background technique [0002] At present, when the copper-lead mixed concentrate obtained by the flotation of copper-lead mixed raw ore is separated from copper and lead by the copper-suppressing and floating-lead method, the flotation separation method is usually used, and sodium cyanide or potassium cyanide reagent is used in the flotation separation process. As an inhibitor of copper sulfide minerals. [0003] The shortcoming of above-mentioned prior art is: [0004] However, because sodium cyanide or potassium cyanide is highly toxic, it is extremely harmful to the human body and can easily cause death; and sodium cyanide or potassium cyanide has great damage to the environment, so sodium cyanide or potassium cyanide The storage requirements are very strict, resulting in inconvenient use and greater environmen...
