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.
And other minerals in the ore, such as zinc, cannot be separated, resulting in waste

Embodiment Construction

[0011] Prepare the following raw materials in parts by weight (kg): xanthate 36, polyoxyethylene polyoxypropylene glyceryl ether 3, sodium hydroxide 2, sodium sulfide 2, isopropyl ethylthiocarbamate 7, copper sulfate 3, oxalic acid 3, Activator 5;

[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 a collector for copper-zinc separation flotation of copper-zinc ore, mix other components except the active agent, stir at 40°C at 11,000 rpm for 15 minutes, then add the activator, and stir at 8,000 rpm...

Abstract

The invention provides a collector for copper and zinc separating flotation of copper-zinc ore. The collector is prepared from xanthate, polyoxyethylene-polyoxypropylene oxide glyceryl ether, sodium hydroxide, sodium sulfide, isopropyl ethyl thionocarbamate, copper sulfate, oxalic acid and an activator. The collector has the double properties of collecting and blistering, the copper mineral sulfide selectivity is good, the copper mineral sulfide collecting capacity is strong, the efficient separation of copper and zinc can be realized at the pH value of 7-11, and the grade and recovery rate of copper and zinc concentrates can be increased effectively, so that the copper-zinc ore collector has a wider scope of application.

Description

technical field [0001] The invention relates to a collector for copper ore dressing, in particular to a collector for copper-zinc separation and flotation of copper-zinc 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...
