Abstract

The invention provides a copper ore flotation collector. The collector is prepared from diesel oil, sodium dodecylbenzene sulfonate, sodium naphthenate, polyvinyl alcohol, sodium carbonate, sodium pyrosulfite, triethylene tetramine, kerosene and an activator. According to the copper ore flotation collector, the adopted main raw material is biodiesel oil, so that the cost is reduced to some extent and is lower than that of traditional copper ore collectors, the recovery rate is increased while the quality of copper ore is improved, and meanwhile, a new way is provided for the use of the diesel oil.

Description

A kind of copper ore floatation collecting agent

Technical field

The present invention relates to flotation collector, particularly a kind of flotation collector for copper mine.

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 ore floatation collecting agent, the main body raw material diesel oil that the present invention adopts, cost decreases, therefore collecting agent of the present invention is lower than traditional copper ore collecting agent cost, when improving the copper mine quality, improved the rate of recovery, the utilization for diesel oil simultaneously provides a kind of new way.

Technical scheme of the present invention is as follows:

This copper ore floatation collecting agent is made by the raw material of following weight portion (kilogram):

Diesel oil 40-42, neopelex 3-4, sodium naphthenate 12-15, polyvinyl alcohol 4-5, sodium carbonate 2-3, sodium pyrosulfite 3-4, triethylene tetramine 1-2, kerosene 12-15, 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, under 40-45 ℃, stir 10-15 minute under 8000-12000 rev/min, then add activator, stir 20-30 minute under 6000-8000 rev/min and get final product.

Collecting agent of the present invention is lower than traditional copper ore collecting agent cost, when improving the copper mine quality, has improved the rate of recovery, and the utilization for diesel oil simultaneously provides a kind of new way.

The specific embodiment

Prepare the raw material of following weight portion (kilogram): diesel oil 41, neopelex 3, sodium naphthenate 13, polyvinyl alcohol 4, sodium carbonate 3, sodium pyrosulfite 4, triethylene tetramine 2, kerosene 13, 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.

Prepare the cupric oxide ore beneficiation collecting agent, 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 cupric oxide ore, and result of the test: the copper productive rate reaches 4.6%, and copper grade reaches 19.2%, and copper recovery reaches 90.5%.
