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 copper-zinc ore flotation agent, made of the following raw materials in parts by weight (kg): 16 thiazonitrile, 22 ethyl cyanogen isopropyl xanthate, 5 sodium alginate, 5 zinc sulfate, and 1.5 sodium sulfide , Isopropyl ethyl thiocarbamate 7, sodium citrate 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 copper-zinc ore flotation agent is characterized in that: mixing other components except the activator, stirring at 48°C for 14 minutes at 10,000 rpm, then adding the activator, and stirring at 7,000 rpm Minutes under sti...

Abstract

A copper and zinc ore flotation agent comprises, by weight, 14-17 parts of cyanoethyl diethyl dithionocarbamate, 20-24 parts of isopropyl xanthate ethyl cyanide, 4-6 parts of sodium alginate, 4-7 parts of zinc sulfate, 1-2 parts of sodium sulfide, 6-8 parts of isopropyl ethyl thionocarbamate, 4-7 parts of sodium citrate and 4-5 parts of activating agents. According to the flotation agent, bubble performance is good, foam is stable, the flocculation effect is good, the performance for collecting copper is good, the yield of the copper is high, chemical selectivity is good, the copper can be efficiently separated from zinc at the pH value ranging from seven to eleven, in this way, the grade of copper ore can be effectively improved, and the recovery rate can be effectively increased; the activating agents are dispersed and stable, good in permeability and activating performance and long in activating effect duration, therefore, the yield of the copper can be increased, and the grade of the copper can be improved.

Description

technical field [0001] The invention relates to the field of mineral flotation agents, in particular to a copper-zinc ore 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 meet the...
