Abstract
The invention provides a collector for copper and zinc separating flotation of copper-zinc ore. The collector is prepared from xanthate, polyoxyethylene-polyoxypropylene oxide glyceryl ether, sodium hydroxide, sodium sulfide, isopropyl ethyl thionocarbamate, copper sulfate, oxalic acid and an activator. The collector has the double properties of collecting and blistering, the copper mineral sulfide selectivity is good, the copper mineral sulfide collecting capacity is strong, the efficient separation of copper and zinc can be realized at the pH value of 7-11, and the grade and recovery rate of copper and zinc concentrates can be increased effectively, so that the copper-zinc ore collector has a wider scope of application.
Description
Technical field
The present invention relates to the copper ore dressing collecting agent, particularly a kind of collecting agent for copper zinc ore copper-zinc separate flotation.
Background technology
At present, China to select smelting copper mineral raw material be mainly chalcopyrite, vitreous copper, bornite, malachite etc.Press the selecting and smelting technology condition, Copper Ores is marked to three natural types with the ratio of cupric oxide and copper sulfide.Be sulfide ore, containing cupric oxide, be less than 10%; Oxidized ore, be greater than 30% containing cupric oxide; Mixed ore, containing cupric oxide 10%～30%.
The collecting agent that occupies leading position in current copper ore floatation technique is the floating agents such as xanthates, thiophosphate and mercaptan, thiamines ester, xanthate, black powder ester, xanthate, but in actual ore dressing, the many requirements that can not reach design of result, copper, sulphur content are from undesirable, in the copper concentrate product, sulfur-bearing exceeds standard, the copper concentrate rate of recovery is on the low side, causes the waste of mining deposits.And other mineral products in ore, as zinc etc. can not separate, cause waste.
Summary of the invention
The collecting agent that the purpose of this invention is to provide a kind of copper zinc ore copper-zinc separate flotation, described collecting agent has collecting and foaming double attribute, selectively good to copper sulfide mineral, collecting ability is strong, can realize the efficient separation of copper, zinc in pH value 7～11 scopes, can effectively improve copper, zinc concentrate grade and the rate of recovery, be a kind of copper zinc ore collecting agent that the wider scope of application is arranged.
Technical scheme of the present invention is as follows:
The collecting agent of this copper zinc ore copper-zinc separate flotation is made by the raw material of following weight portion (kilogram):
Xanthate 34-38, polyoxyethylene polyoxypropylene glycerin ether 2-3, NaOH 1-2, vulcanized sodium 1-2, isopropyl ethyl thiourethane 6-8, copper sulphate 2-3, oxalic acid 2-3, activator 4-5;
Described activator is made by the raw material of following weight portion (kilogram): soybean oil 12-15, sodium lignin sulfonate 2-3, silane resin acceptor kh-550 1-2, rosin acid polyoxyethylene ester 2-3, dimethicone 4-5, fumaric acid 2-3, EDTA5-8; Its preparation method is that soybean oil, sodium lignin sulfonate, silane resin acceptor kh-550, rosin acid polyoxyethylene ester are mixed, and is heated to 60-65 ℃, then adds dimethicone, stir after 20-30 minute, add again residual components, continue to stir 45-60 minute, obtain.
The collecting agent for preparing copper zinc ore copper-zinc separate flotation: other composition except activating agent is mixed, under 40-45 ℃, stir 10-15 minute under 8000-12000 rev/min, then add activator, stir 15-30 minute under 6000-8000 rev/min and get final product.
Collecting agent of the present invention has collecting and foaming double attribute, selectively good to copper sulfide mineral, collecting ability is strong, can realize the efficient separation of copper, zinc in pH value 7～11 scopes, can effectively improve copper, zinc concentrate grade and the rate of recovery, be a kind of copper zinc ore collecting agent that the wider scope of application is arranged.
The specific embodiment
Prepare the raw material of following weight portion (kilogram): xanthate 36, polyoxyethylene polyoxypropylene glycerin ether 3, NaOH 2, vulcanized sodium 2, isopropyl ethyl thiourethane 7, copper sulphate 3, oxalic acid 3, activator 5;
Prepare activator, at first prepare the raw material of following weight portion (kilogram): soybean oil 12, sodium lignin sulfonate 2, silane resin acceptor kh-550 1.5, rosin acid polyoxyethylene ester 2, dimethicone 4, fumaric acid 2, EDTA 7; Its preparation method is that soybean oil, sodium lignin sulfonate, silane resin acceptor kh-550, rosin acid polyoxyethylene ester are mixed, and is heated to 65 ℃, then adds dimethicone, after stirring 25 minutes, then adds residual components, continues to stir 50 minutes, obtains.
The collecting agent for preparing copper zinc ore copper-zinc separate flotation, mix other composition except activating agent, under 40 ℃, stirs 15 minutes under 11000 rev/mins, then add activator, stirs 20 minutes under 8000 rev/mins and get final product.
The present invention is for the flotation of copper zinc ore, and result of the test: the copper productive rate reaches 3.6%, and copper grade reaches 15.1%, and copper recovery reaches 91.3%.
