Abstract

The invention relates to an ore dressing technology for separating copper, lead and zinc in complex polymetallic sulphide ores, in particular to an electric potential modulation and preferential flotation process for copper-lead-zinc sulphide ores, which comprises the steps of copper, lead and zinc selection; copper is preferentially floated; the electric potential Eh of an ore slurry is between 35 below zero and 15 below zero mV; the PH value of the ore slurry is between 7.50 and 8.50; LP-01 is used as a collecting agent; and YN and ZnSO4 are used as inhibitors. The process has the advantages of solving the problems that the prior flotation process has large difficulty in separating the copper and lead and the copper and zinc, poor quality of concentrated ore and higher cost.

Description

technical field

[0001] The invention relates to an ore dressing technology for flotation separation of copper, lead and zinc in complex polymetallic sulfide ores, in particular to a priority flotation process for potential regulation and control of copper, lead and zinc sulfide ores. Background technique

[0002] Due to the difficulty of copper-lead separation and copper-zinc separation, because the content of individual metal elements in most copper-lead-zinc polymetallic symbiotic ores is low, and because copper sulfide, lead, and zinc minerals are minerals with similar thermodynamic properties, when they are separated from each other The difficulty is relatively large, which makes it difficult to effectively separate copper sulfide minerals and lead-zinc sulfide minerals. In production, the recovery rate of main metals in copper, lead, and zinc concentrates is low, and the impurity content is high. For these copper, lead, zinc symbiotic or associated polymetallic sulfide ...
