Abstract
The invention provides a collecting agent for flotation of copper sulphide ore, and a preparation method of the collecting agent. The collecting agent is prepared by dithiophosphate, propylene butyl sulfonate, potassium dichromate, sodium metasilicate, starch, sodium hydroxide and activating agent. The mineral separation collecting agent is good in selectivity, and can obtain the concentrate grade higher than the original collecting agent; compared with the traditional collecting agent, the collecting agent provided by the invention improves the copper recovery rate by about 8.5% and greatly reduces the mineral separation cost; the collecting agent has wider adaptability for the raw ore with higher argillation degree.
Description
Technical field
The present invention relates to the technique of preparing field, particularly a kind of collecting agent for floating cupric sulfide ore 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 collecting agent of a kind of floating cupric sulfide ore and preparation method thereof, it can obviously improve beneficiating technology index, can obtain the concentrate grade higher than former collecting agent; With traditional collecting agent, compare, copper recovery improves.
Technical scheme of the present invention is as follows:
The collecting agent of this floating cupric sulfide ore is made by the raw material of following weight portion (kilogram):
Black powder 12-14, fourth yellow acid propylene 4-6, potassium bichromate 1-2, sodium metasilicate 2-3, starch 1-2, NaOH 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, then add activator, stir 15-30 minute under 6000-8000 rev/min and get final product.
Beneficiation collecting agent of the present invention, collecting agent is selectively good, can obtain the concentrate grade higher than former collecting agent; With traditional collecting agent, compare, copper recovery improves approximately 8.5%, can greatly reduce beneficiation cost; To the argillization degree, higher raw ore has adaptability widely.
The specific embodiment
Prepare the raw material of following weight portion (kilogram): black powder 13, fourth yellow acid propylene 6, potassium bichromate 2, sodium metasilicate 3, starch 2, NaOH 2, 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.
Other composition except activating agent is mixed, then add activator, stir 20 minutes under 7000 rev/mins and get final product.
The present invention has flotation for copper-sulphide ores, and in ore deposit, cupric oxide 8.3%, result of the test: the copper productive rate reaches 3.4%, and copper grade reaches 18.8%, and copper recovery reaches 91.5%.
