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, the separation of copper and sulfur is not ideal, the sulfur content in copper concentrate products exceeds the standard, and the recovery rate of copper concentrate is low, resulting in a waste of mineral resources.

Embodiment Construction

[0011] Prepare the following raw materials in parts by weight (kg): propionitrile alkyl xanthate 14, black medicine 12, distyrylphenol polyoxyethylene ether 3, polyoxyethylene oleate 2, triethylenetetramine 4, water Carylic acid 5, activator 4;

[0012] To prepare the activator, first prepare the following raw materials in parts by weight (kg): soybean oil 12, sodium lignosulfonate 2, silane coupling agent KH-550 1.5, rosin acid polyoxyethylene ester 2, dimethyl silicone oil 4, rich Malic acid 2, EDTA 7; the preparation method is to mix soybean oil, sodium lignosulfonate, silane coupling agent KH-550, polyoxyethylene abietic acid, heat to 65°C, add simethicone, and stir After 25 minutes, add the remaining ingredients and continue to stir for 50 minutes.

[0013] To prepare the copper oxide ore dressing collector, mix other components except the active agent, stir for 15 minutes, then add the activator, and stir for 20 minutes at 7000 rpm.

[0014] The flotation of the nickel...

Abstract

The invention provides a copper sulfide ore collector. The collector is prepared from alkyl xanthogen propionitrile ester, black powder, diphenylethylphenol polyoxyethylene ether, oleic acid polyoxyethylene ester, triethylene tetramine, salicylic acid and an activator. The collector has the characteristics of double attributes of collection and bubbling, high selectivity, strong collection capacity, stable floatation foam, high mineral floating speed and capability of effectively improving the concentrate grade and the recovery rate, and is a very ideal selective collector for copper-nickel ore.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a collector for copper sulfide ore. 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 design requirements, the separ...
