Abstract

The present invention relates to a floatation separation mineral concentration technology for metal sulfuration mine, especially a technique for floatation separation of hard washing copper zinc sulfuration mine. The copper ore concentrate quality produced by a general copper-zinc differential flotation technique at the present time is low and cost is high. The technique of the invention includes a step of selecting copper and selecting zinc, the copper is floated firstly, the copper and the zinc is separated by using a collecting agent LP-02 with the addition of a combined inhibitor LY-02 under a neutrality condition of the slurry pH value. The technique has a strong adaptability, a stable production target; it is not only used for recovering copper, also improves the quality of the copper and zinc ore concentrate, as well as the copper and zinc recovery rate; the production cost is reduced greatly, the earnings level is improved and it has non environmental pollution.

Description

technical field

[0001] The invention relates to metal sulfide ore flotation separation ore dressing technology, in particular to a process for refractory copper-zinc sulfide ore flotation separation. Background technique

[0002] Due to the difficulty of copper-zinc separation, because the content of individual metal elements in most copper-zinc polymetallic symbiotic ores is low, and because copper sulfide and zinc minerals are minerals with similar thermodynamic properties, it is difficult to separate each other, which leads to copper sulfide It is difficult to effectively separate minerals and zinc sulfide minerals, which is manifested in the low recovery rate of main metals in copper and zinc concentrates and high impurity content in production. For these copper-zinc symbiotic or associated polymetallic sulfide ores, most mines either only separate a single copper concentrate, or separate a zinc concentrate, or are not effectively developed due to the difficulty of benef...
