Embodiment

[0021] refer to figure 1 As shown, in the flotation of lead-zinc sulfide ore, the raw ore is ground and then the lead separation operation is carried out. After the lead separation, the tailings pulp has a mass concentration of 35-38% and a mineral particle size of -0.074mm in the pulp. 73-78%.

[0022] Add 200-300g / t pyrite inhibitor HD52 to the tailings slurry in the last scavenging flotation tank of lead selection to inhibit the floating of pyrite, and add it to the slurry mixing tank before zinc selection and roughing The dosage is 300-400g / t copper sulfate for activating sphalerite, adding 17-20g / t ethyl thiocarbamate for stirring and pulping, and then the slurry enters the zinc roughing flotation machine for zinc roughing.

[0023] The zinc roughing concentrate enters the zinc concentration 1 flotation machine for the first zinc concentration, the zinc concentration 1 concentrate enters the zinc concentration 2 flotation machine for the second zinc concentration, and th...

Abstract

The invention discloses an efficient collecting agent for zinc separation of lead-zinc sulfide ore. The efficient collecting agent for zinc separation is ethyl thionocarbamate. The invention further discloses a method for separating zinc from the lead-zinc sulfide ore. The method comprises the following steps that in flotation of the lead-zinc sulfide ore, raw ore is ground, and then lead separation operation is conducted; a pyrite inhibitor HD52 is firstly added into tailing pulp of the last scavenging of lead flotation; then, copper sulfate is added into the slurry mixing and stirring barrel before zinc selection and roughing, and ethyl thionocarbamate is added for stirring and size mixing; and then the ore pulp enters a zinc roughing flotation machine for zinc roughing. According to the method, ethyl thionocarbamate is adopted as a zinc collecting agent in flotation of the lead-zinc sulfide ore, so that the sphalerite and the pyrite can be separated by adopting ethyl thionocarbamate with good selectivity to the sphalerite as the collecting agent of the sphalerite under the condition of a natural PH value.

Description

technical field [0001] The invention relates to a high-efficiency collector for zinc beneficiation of lead-zinc sulfide ore and its application. Background technique [0002] The sorting of domestic lead-zinc sulfide ore generally involves suppressing pyrite (sulfur) under high-alkali process conditions, and using xanthate collectors to collect sphalerite to obtain zinc concentrate products. In actual production, such as mineral processing The PH value of wastewater is high, the follow-up treatment is difficult, and the treatment cost is high; the preparation of lime milk is labor-intensive and the labor cost is high; the pipeline is easy to block during the lime transportation process, which affects the beneficiation production; the concentration of sulfur concentrate pulp is low, and the amount of wastewater is large , the cost of wastewater treatment is high; due to the addition of a large amount of lime in the separation operation, lime slag enters the sulfur concentrate...
