Abstract
The invention provides a beneficiation reagent for mixed copper sulfide and oxide ore. The collector is prepared from oleic acid, sodium carbonate, sodium silicate, styryl phosphonic acid, hydroxybutyl vinyl ether, quick lime and an activator. The collector has the characteristics of high grading efficiency, high yield, low reagent cost, less using amount, simple and reliable process flow, easiness in operation, small investment, low beneficiation cost and the like, and is suitable for beneficiation application of composite mixed copper sulfide and oxide ore.
Description
Technical field
The present invention relates to select copper ore collecting agent, particularly the beneficiation reagent of a kind of sulfuration, oxidization mixing copper ore.
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 beneficiation reagent that the purpose of this invention is to provide a kind of sulfuration, oxidization mixing copper ore, there are the characteristics such as the efficiency of sorting is high, yield is large, reagent cost is low, consumption is few, technological process is simple and reliable, easy operating, investment is little, beneficiation cost is low, be suitable for complicated sulfuration, oxidization mixing copper ore ore dressing application.
Technical scheme of the present invention is as follows:
The beneficiation reagent of this sulfuration, oxidization mixing copper ore is made by the raw material of following weight portion (kilogram):
Oleic acid 24-27, sodium carbonate 12-14, sodium metasilicate 30-34, styryl phosphonic acid 17-19,4-hydroxy butyl vinyl ether 3-4, quick lime 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 adds activator, under 6000-8000 rev/min, stir within 15-30 minute, vulcanized, the beneficiation reagent of oxidization mixing copper ore.
The present invention has the characteristics such as the efficiency of sorting is high, yield is large, reagent cost is low, consumption is few, technological process is simple and reliable, easy operating, investment is little, beneficiation cost is low, is suitable for complicated sulfuration, oxidization mixing copper ore ore dressing application.
The specific embodiment
Prepare the raw material of following weight portion (kilogram): oleic acid 25, sodium carbonate 13, sodium metasilicate 33, styryl phosphonic acid 18,4-hydroxy butyl vinyl ether 4, quick lime 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, EDTA7; 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, 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, then add activator, stir the beneficiation reagent that obtains sulfuration, oxidization mixing copper ore in 20 minutes under 7000 rev/mins.
The present invention is for the flotation of mixed copper ore, and cupric oxide content is 23% left and right, result of the test: the copper productive rate reaches 4.7%, and copper grade reaches 18.3%, and copper recovery reaches 92.5%.
