Abstract
A copper sulphide ore dressing flotation agent is prepared by the following raw materials in part by weight: 10-12 parts of epoxidized soybean oil, 15-20 parts of N-hydroxyl and carbonyl sulfourea, 18-23 parts of butyl xanthate, 6-8 parts of xanthate, 12-14 parts of glycerinum, 3-4 parts of sodium citrate, 3-5 parts of sodium thiosulfate, 3-5 parts of sodium trithiocarbonate, 2-3 parts of polyoxyethylated castor oil and 4-5 parts of activating agents. The pH (power of hydrogen) value and the foams of the flotation agent are stable; a flocculation effect is high; collecting performance of chemicals on copper is high; the yield of the copper is high; the chemical selectivity is high; the rejection capability on other ores is high; and the grade of the copper is also high. The activating agents contain ingredients such as nanometer jade powder, are dispersed stably, and are high in permeability and activation property; activating effect lasting time is long; the yield and the grade of the copper can be improved; and environmental pollution of the flotation agent is low.
Description
Technical field
The present invention relates to mineral flotation agent field, particularly a kind of copper-sulphide ores ore dressing flotation 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 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, is 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, often occur that copper, sulphur content are from undesirable, the phenomenon that in copper concentrate product, sulfur-bearing exceeds standard; Also have the productive rate of copper low, the copper concentrate rate of recovery is on the low side, causes the waste of mining deposits.
Summary of the invention
The object of this invention is to provide a kind of copper-sulphide ores ore dressing flotation agent and preparation method thereof, this flotation agent has pH value stabilization, foam stabilization, and solidifying wadding is effective, and collecting performance is good, selectively good, the advantage that activation effect is good.
Technical scheme of the present invention is as follows:
A kind of copper-sulphide ores ore dressing flotation agent, is characterized in that being made by the raw material of following weight portion: epoxidized soybean oil 10-12, N-hydroxyl oxygen base carbonyl thiocarbamide 15-20, butyl xanthate 18-23, xanthate 6-8, glycerine 12-14, natrium citricum 3-4, dodium thiosulfate 3-5, trithiocarbonic acid sodium 3-5, Emulsifier EL-60 2-3, activator 4-5;
