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 design requirements, and the separation of copper and sulfur often occurs unsatisfactorily, and the sulfur content in copper concentrate products exceeds the standard; in addition, the yield of copper is low, and the recovery rate of copper concentrate is low. , resulting in a waste of mineral resources

Embodiment Construction

[0011] A low-grade chalcopyrite flotation agent, made of the following raw materials in parts by weight (kg): butyl ammonium black drug 25, sulfonated tall oil 3.5, pyrophosphate 4, nano-titanium dioxide 2.5, diethylene glycol methyl Ether 7, silicone resin polyether emulsion 6, diesel oil 13, sodium thiosulfate 18, nitrile nitrile ester 22, 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 low-grade chalcopyrite flotation agent is: mix other components except the activator and nano-titanium dioxide, stir at 48°C for 13 minutes at 10,00...

Abstract

The invention discloses a low-grade chalcopyrite flotation agent which is prepared from the following raw materials in parts by weight: 23-27 parts of ammonium dibutyl dithiophosphate, 3-4 parts of sulfonated tall oil, 3-5 parts of pyrophosphoric acid, 2-3 parts of nanometer titania, 6-8 parts of dipolyethylene glycol methyl ether, 5-7 parts of silicone polyether emulsion, 10-15 parts of diesel oil, 16-19 parts of sodium thiosulfate, 20-24 parts of butyl xanthate nitrile ester and 4-5 parts of activating agent. Since the nanometer titania is added, the flotation agent is good in dispersion and flocculation effect, the foam is stable and the collecting effect is enhanced; in addition, the low-grade chalcopyrite flotation agent has the advantages of good collecting effect, high copper yield, good medicine selecting property, good inhibiting property for other ores and high copper grade. The activating agent in the low-grade chalcopyrite flotation agent has the advantages of stable dispersion, good permeation, good activating property and long activating effect duration; the yield and the grade of copper can be improved.

Description

technical field [0001] The invention relates to the field of mineral flotation agents, in particular to a low-grade chalcopyrite 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 results often fail to m...
