Problems solved by technology

Within a certain range of collector concentration, as the concentration of the agent increases, the adsorption capacity increases, and the flotation recovery rate increases significantly; when the concentration reaches a certain value, the recovery rate decreases with the increase in concentration and adsorption capacity; When the concentration is too high, the adsorption capacity can continue to increase, but the flotation recovery rate no longer increases, or even decreases.

Abstract

The invention provides a composite beneficiation reagent based on chemical industry production. The composite beneficiation reagent is constituted by following raw materials of oleic acid, sodium silicate, styrene phosphonic acid, quicklime, diesel oil, sodium oleate, sodium fluoride, sodium sulfide, and aniline aerofloat. Compared with the prior art, the composite beneficiation reagent has the following beneficial effects that screening of sulfide ore containing silver has the advantages and characteristics that the grading efficiency is high, the yield is large, the reagent cost is low, theusing amount is small, the technical process is simple and reliable, operation is easy, investment is small, and the beneficiation cost is low.

Description

technical field [0001] The invention is a compound ore dressing agent based on chemical production, which belongs to a compound strong collector. Background technique [0002] The beneficiation process mainly adopts the priority flotation process, that is, the priority flotation of lead, and the flotation of zinc after regrinding of medium ore. The raw ore contains 25%-28% sulfur, 2.5%-2.8% lead, 2.6%-3.0% zinc, and 145g / t-165 g / t silver. The silver in this ore is mainly associated with lead. The beneficiation plant mainly uses ethyl disulfide nitrogen and 541 xanthate collectors as lead collectors, and the recovery rate of associated silver metal is low. [0003] Silver metal will be associated in many kinds of ores, generally associated with other metals, rarely ore-forming alone (a few will be ore-forming alone), it is mainly associated in lead concentrates, and can be enriched in lead concentrates The grade is above 2000; zinc concentrate can also be enriched to about ...
