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...
