Problems solved by technology

[0003] The collectors that occupy a dominant position in the current copper ore flotation process are flotation agents such as xanthate, thiophosphate, mercaptan, thiamine ester, xanthate, black drug ester, and xanthate. However, in the actual beneficiation, the results often fail to meet the desig

Embodiment Construction

[0011] A high-yield copper sulfide ore separation flotation agent, made of the following raw materials in parts by weight (kg): engine oil 13, phenethyl ester oil 11, lime 2.5, O-isopropyl-N-ethylthiocarbamate Ester 18, sodium sulfide 5, sodium mercaptoacetate 5, xanthate 26, chitosan 6, swire oil 2.5, polyether modified silicone oil 1.5, activator 4.5;

[0012] The activator is made of the following raw materials in parts by weight (kg): fumed white carbon black 3, jojoba oil 2.5, butylparaben 2.5, silane coupling agent KH-550 1.5, penetrant T 2.5, cis Butenedioic acid 2-2-octyl sodium sulfonate 2.5, isocyanate 5, CuSO 4 6. Disodium hydrogen phosphate 5, water 45; the preparation method is to mix the raw materials, heat to 63°C, and stir at 2300 rpm for 45 minutes to obtain the product.

[0013] The preparation method of the high-yield copper sulfide ore separation flotation agent is as follows: mix other components except the activator, stir at 48°C for 13 minutes at 10,00...

Abstract

High-yield copper sulphide ore flotation agents are made from the following raw materials including by weight, 10-15 parts of engine oil, 9-13 parts of phenethyl phenylacetate oil, 2-3 parts of lime, 15-20 parts of O-isopropyl-N-sulfur ethyl carbamate, 4-6 parts of sodium sulphide, 4-6 parts of sodium mercaptoacetate, 24-27 parts of xanthate, 5-7 parts of chitosan, 2-3 parts of Turkey red oil, 1-2 parts of polyether modified silicone and 4-5 parts of activating agents. The high-yield copper sulphide ore flotation agents are good in copper collecting performance, high in copper yield, good in selectivity, good in rejection capability of other minerals, high in copper grade, stable in pH value, stable in foam and good in flocculation effect. The activating agents comprise nanometer jade powder and other constituents, are stable in dispersion, good in permeability and activation performance, long in duration time of the activation time and capable of improving the yield and grade of copper. The high-yield copper sulphide ore flotation agents can obviously improve the metal recovery rate of copper sulphide ore, make full and effective use of ore resources and create good economical and social benefits.

Description

technical field [0001] The invention relates to the field of mineral flotation agents, in particular to a high-yield copper sulfide ore separation flotation agent and a preparation method thereof. Background technique [0002] At present, the raw materials of copper mineral dressing and smelting in my country are mainly chalcopyrite, chalcocite, bornite, malachite and so on. According to the technical conditions of dressing and smelting, copper ore is divided into three natural types according to the ratio of copper oxide and copper sulfide. That is, sulfide ore, containing less than 10% copper oxide; oxidized ore, containing more than 30% copper oxide; mixed ore, containing 10% to 30% copper oxide. [0003] The collectors that occupy a dominant position in the current copper ore flotation process are flotation agents such as xanthate, thiophosphate and mercaptan, thiamine ester, xanthate, black drug ester, and xanthate. However, in the actual beneficiation, the resul...
