Abstract
The invention provides a compounded flotation collector for copper ore and a preparation method thereof. The collector is prepared from phthalate, carboxymethyl cellulose, polyvinyl pyrrolidone, Tall oleic acid, benzoxazole mercaptan and an activator. The compounded flotation collector has the characteristics that the low-temperature fluidity is good, the blistering speed is high, the blistering duration is long, the dispersity in ore slurry is good, the capacity of collecting coarse-grain-grade or ultrafine-grain-grade minerals is strong, and the like.
Description
Technical field
The present invention relates to the copper ore dressing collecting agent, particularly a kind of copper mine combined flotation collecting agent and preparation method thereof.
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.
Summary of the invention
The purpose of this invention is to provide a kind of copper mine combined flotation collecting agent and preparation method thereof, this combined flotation collecting agent has that low temperature flow is good, lather quickness is fast, the duration of bubbling is long, in ore pulp dispersive property good, to coarse fraction or the characteristics such as ultra-fine grade mineral collecting ability is strong.
Technical scheme of the present invention is as follows:
This copper mine combined flotation collecting agent is made by the raw material of following weight portion (kilogram):
Phthalic acid ester 3-4, carboxymethyl cellulose 2-3, polyvinylpyrrolidone 4-6, appropriate youngster's oleic acid 3-5, benzo uh azoles mercaptan 14-16, activator 3-4;
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.
Other composition except activating agent is mixed, stir 10-15 minute, then add activator, stir 15-30 minute under 6000-8000 rev/min and get final product.
Combined flotation collecting agent of the present invention has that low temperature flow is good, lather quickness is fast, the duration of bubbling is long, in ore pulp dispersive property good, to coarse fraction or the characteristics such as ultra-fine grade mineral collecting ability is strong.
The specific embodiment
Prepare the raw material of following weight portion (kilogram): phthalic acid ester 3, carboxymethyl cellulose 3, polyvinylpyrrolidone 5, appropriate youngster's oleic acid 4, benzo uh azoles mercaptan 15, activator 3;
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.
Other composition except activating agent is mixed, under 40 ℃, stir 15 minutes under 10000 rev/mins, then add activator, stir 20 minutes under 7000 rev/mins and get final product.
The present invention is for the flotation of copper-sulphide ores, and result of the test: the copper productive rate reaches 3.2%, and copper grade reaches 15.1%, and copper recovery reaches 90.4%.
