Embodiment 1

[0012] Weigh the by-products of ethanol production and each 76g (weight ratio 1: 1) of carbon disulfide, sodium hydroxide 40g, the component of the by-products of ethanol production is (W%): isoamyl alcohol 51.72%, ethanol 13.42%, propanol 19.78%, isobutanol 9.63, water and a small amount of other organic compounds 5.45%. Heat with a constant temperature water bath and control the temperature at 25°C, stir with a mechanical stirrer with a rotating speed of 1200 rpm, add sodium hydroxide fine powder, control the reaction temperature at 25-35°C and stir for 1 hour to make the material react completely. After cooling, about 186 g of powdery solid was obtained. The infrared spectrum of the obtained powdery solid is as follows figure 1 As shown, its main components are: isoamylxanthate, ethyl xanthate, propyl xanthate, and isobutyl xanthate.

Embodiment 2

[0014] Take by-product fusel oil 45.6g of alcohol production and each 38g (weight ratio 1.2: 1) of carbon disulfide, sodium hydroxide 20g, the component of the by-product of alcohol production is (W%): isoamyl alcohol 54.38%, ethanol 15.14%, propanol 17.56%, butanol 3.29%, isobutanol 8.75 and a small amount of water. Heat with a constant temperature water bath and control the temperature at 30°C, stir with a mechanical stirrer, add sodium hydroxide fine powder, control the reaction temperature and stir at 30°C to make the material react completely, and cool to obtain a powdery solid. Its main components are: isoamylxanthate, ethylxanthate, propylxanthate, butylxanthate and butylxanthate.

Embodiment 3

[0016] Experimental research has been carried out on the gold-silver-bearing copper ore in Tonglushan, Hubei by using the collector of the present invention. The ores mainly include malachite, false malachite, copper orchid, chalcopyrite, chalcocite, magnetite, hematite, limonite, quartz, chalcedony, and clay minerals. The copper sulfide ore of this ore accounts for 94.53%; the sulfide copper-monoxide mixed ore contains 3.31% Cu, and the copper oxidation rate is 57.1%; the copper oxide ore contains 2.24% Cu (the oxidation rate is 92.86%). The incorporation rate of copper is 15.63%. The ore is a refractory ore with high oxidation rate and high mud content. Mineral dressing is very difficult, and the original flotation index of vulcanization first and then single xanthate is low. By adopting the collector of the present invention to carry out flotation of Tonglushan copper oxide ore, a better concentrate index is obtained than using a single xanthate, and correspondingly reduc...

Abstract

The invention relates to a collecting agent used for beneficiation, which is prepared by using byproducts of alcohol as raw material while the byproducts are produced by a fermentation method. Carbon disulfide and the materials are mixed according to a mass ration of 1:1 to 1:2. Sodium hydroxide fine powder is added while stirring and a reaction temperature is controlled between 15 and 35 DEG C, and the materials react completely and then are cooled to obtain the lemon yellow collecting agent used for beneficiation. Production raw materials adopted by the invention have wide sources and low cost and a deep processing treatment of the production raw materials can not only abate environmental pollution, but also reduce production costs. The collecting agent produced by the invention has comparatively high selection and collection performance for sulphide minerals, particularly has comparatively high collection capacity and comparatively good selectivity for minerals containing gold, silver and copper, etc. Simultaneously the collecting agent produced by the invention has a certain foaming property.

Description

technical field [0001] The invention relates to the production and application of a beneficiation agent, in particular to a flotation collector suitable for copper ore, which belongs to the nonferrous metal ore flotation agent. Background technique [0002] The invention adopts the by-products produced by the fermentation method as raw materials. The by-product of alcohol production by fermentation is a yellow to reddish-brown translucent liquid, which is lighter than water and has a strong pungent odor that is difficult to remove. Many enterprises directly discharge it as wastewater, and the pollution it causes to the environment is self-evident. With the development of my country's alcohol industry, the output of this waste liquid is gradually increasing. If it can be fully utilized, it can not only reduce the pollution to the environment, but also greatly reduce the cost of beneficiation, achieving a win-win situation of social and economic benefits. [0003] So far, th...
