Abstract
The invention provides a copper ore flotation collector and an application method thereof. The collector is prepared from sodium butyl xanthate, kerosene, terpenic oil, O-alkyl-N-alkyl thionocarbamate, black powder, xanthan gum, alum and an activator. According to the collector, the recovery index is increased effectively; meanwhile, compared with conventional medicaments, the collector provided by the invention has the advantages of low dosage, good index, little pollution and the like.
Description
Technical field
The present invention relates to beneficiation collecting agent, particularly a kind of collecting agent of copper ore floatation and using 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 collecting agent and the using method thereof that the purpose of this invention is to provide a kind of copper ore floatation, described collecting agent has effectively improved recovery index simultaneously, and this combination medicament has the advantages such as consumption is low, index good, pollution is few than conventional dose.
Technical scheme of the present invention is as follows:
The collecting agent of this copper ore floatation is made by the raw material of following weight portion (kilogram):
Sodium n-butyl xanthate 16-19, kerosene 4-6, terpenic oil 12-14, O-alkyl-N-alkyl sulfide are by carbamate 7-9, black powder 14-16, xanthans 2-3, alum 1-2, 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.
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.
Collecting agent of the present invention has effectively improved recovery index simultaneously, and this combination medicament has the advantages such as consumption is low, index good, pollution is few than conventional dose.
The specific embodiment
Prepare the raw material of following weight portion (kilogram): sodium n-butyl xanthate 17, kerosene 5, terpenic oil 13, O-alkyl-N-alkyl sulfide are by carbamate 8, black powder 15, xanthans 3, alum 2, activator 4;
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.
Adopt the flotation of the present invention for cupric oxide ore, copper grade is 16.26%, the copper concentrate that the rate of recovery is 91.7%, and the flotation tailing copper grade is 0.35%.
