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): diesel oil 34, thiazonitrile ester 10, isopropyl ethyl thiocarbamate 5, phenylethylcumylphenol polyoxyethylene ether 3, p-benzoquinone dioxime 14, Sodium oleate 4, sodium fluoride 4, sodium sulfide 2, 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 copper oxide ore beneficiation collector, mix other ingredients except active agent, stir at 40°C, 10,000 rpm for 15 minutes, then add activator, and stir at 7,000 rpm fo...

Abstract

The invention provides a beneficiation reagent for copper sulfide ore. The reagent is prepared from diesel oil, cyanoethyl diethyl dithionocarbamate, isopropyl ethionine ester, phenylethyl isopropyl phenyl phenol polyoxyethylene ether, para-benzoquinone dioxime, sodium oleate, sodium fluoride, sodium sulfide and an activator. Through application of the reagent in the beneficiation of the copper-nickel polymetallic sulfide ore, the content of magnesium oxide in copper-nickel mixed concentrate can be reduced, and the metal recovery rate of the copper-nickel polymetallic sulfide ore can be obviously improved, so that the existing copper-nickel ore resources are fully, efficiently and comprehensively utilized.

Description

technical field [0001] The invention relates to a copper ore beneficiation agent, in particular to an agent for copper sulfide ore beneficiation. 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 sep...
