Description
One, technical field
The present invention relates to a kind of beneficiation reagent, specifically a kind of method reclaiming zinc oxide from zinc sulphide flotation tailing.
Two, background technology
In oxysulphied zinc ore floating, general first flotation zinc sulphide, Flotation of Zinc Oxide again after mine tailing flotation pyrite.FLOTATION SEPARATION due to zinc sulphide is all adopt high-alkali technique, suppressing pyrite, using copper sulphate for activation zincblende, with butyl xanthate flotation zincblende by adding lime.Owing to adding a large amount of lime, add zinc oxide in rejects flotation recovery difficult, need on the one hand to add sulfuric acid or a large amount of carbonic hydroammonium to eliminate the impact of calcium ion, two is due to a large amount of calcium ion of Zinc oxide minerals adsorption, form calcium carbonate on smithsonite surface, thus the floatability of Zinc oxide minerals is declined.When the lime consumption of flotation zinc sulphide is in suitable scope, can eliminate the impact of mineral surfaces calcium ion by adding carbonic hydroammonium, Zinc oxide minerals can carry out flotation and reclaim with traditional ammonium sulphide method; After zinc sulphide flotation lime consumption exceedes certain limit, the complete other calcium ion of zinc oxide surface covers, Zinc oxide minerals surface forms a schieferspar film, the activators such as carbonic hydroammonium can not produce activation completely, adopt ammonium sulphide method or other zinc oxide collecting agent all flotation can not reclaim zinc oxide.
Three, summary of the invention
The object of the present invention is to provide a kind of method reclaiming zinc oxide from zinc sulphide flotation tailing, in high alkalinity zinc sulphide flotation tailing, effectively can reclaim zinc oxide.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of method reclaiming zinc oxide from zinc sulphide flotation tailing, comprises the steps:
(1) high alkalinity zinc sulphide flotation tailing is concentrated into 45wt%, adds 800g/t-1200g/ citric acid, stirring reaction 10-15 minute;
(2) add vulcanized sodium 2-3kg/t, stirring reaction 5 minutes, then adds clear water, by concentration dilution to 30wt%;
(3) primary octadecylamine acetate 300-500g/t is added, stirring reaction 5 minutes;
(4) add No. 2 oily 120-160g/t, stirring reaction is after 3 minutes, and pH values of pulp, at 8.5-9.5, starts inflation and scrapes bubble flotation, obtains zinc oxide product.
Unless otherwise indicated, percentage of the present invention is mass percent, and each constituent content percentage sum is 100%.
Outstanding advantages of the present invention is:
By citric acid and Zinc oxide minerals surface calcium ion selective complexation effect, by be adsorbed on zinc oxide surface calcium ion dissolve enter solution, realize the cleaning action on Zinc oxide minerals surface.Recover the unsalted surface of Zinc oxide minerals, re-use ammonium sulphide method and carry out collecting.
Next utilizes the activation effect of citric acid, the flotation realizing zinc oxide under high alkalinity is reclaimed, conventional vulcanized amine method Flotation of Zinc Oxide pH values of pulp is at 11.5-12, and adopt the flotation pH of citric acid activated rear oxidation zinc at 8.5-9.5, vulcanized sodium, at 2-3kg/t, decreases a greater part of than traditional handicraft 7-15kg/t vulcanized sodium.
In addition because citric acid is inhibited to gangue mineral, therefore, it is possible to significantly improve zinc oxide flotation grade, zinc oxide grade reaches 45%.
Four, detailed description of the invention
By the following examples technical scheme of the present invention is described further.
Embodiment 1
A kind of method reclaiming zinc oxide from zinc sulphide flotation tailing of the present invention, comprises the steps:
