Problems solved by technology

[0002] Chalcopyrite is mainly copper-iron sulfide, which also contains trace amounts of gold, silver and other substances. It is the most widely distributed type of copper ore and the most important raw material for copper smelting. It is concentrated in Sichuan and Yunnan. There are relatively mature, stable and efficient technologies for extracting copper from ores, but there is still a lot of room for improvement in the existing technologies for the full extraction of copper from low-grade chalcopyrite ores

Embodiment 1

[0012] 1) Mix 1 part of erucic acid, 1 part of maleic acid and 2 parts of low-density polyethylene with a molecular weight of 500, and then stir at 60°C for 10 minutes at a stirring frequency of 10,000 rpm to obtain the first mixture;

[0013] 2) Add 10 parts of dixanthate, 10 parts of ethylene glycol ether, 5 parts of ethanol, 1 part of coupling agent KH5501 and 30 parts of water into the first mixture, and stir for 20 minutes at a temperature of 45 °C and a frequency of 6000 rpm , to obtain the second mixture;

[0014] 3) Add 1 part of sodium dodecylbenzenesulfonate to the second mixture, and stir for 10 minutes at a temperature of 40° C. and a frequency of 10,000 rpm to obtain the chalcopyrite flotation agent.

Embodiment 2

[0016] 1) Mix 5 parts of erucic acid, 5 parts of maleic acid and 10 parts of low-density polyethylene with a molecular weight of 2000, and then stir at 50°C for 20 minutes at a stirring frequency of 5000 rpm to obtain the first mixture;

[0017] 2) Add 20 parts of dixanthate, 15 parts of ethylene glycol ether, 10 parts of ethanol, 3 parts of coupling agent KH5503 and 50 parts of water into the first mixture, and stir for 10 minutes at a temperature of 35 °C and a frequency of 12000 rpm , to obtain the second mixture;

[0018] 3) Add 5 parts of sodium dodecylbenzenesulfonate to the second mixture, and stir for 20 minutes at a temperature of 40° C. and a frequency of 5000 rpm to obtain the chalcopyrite flotation agent.

Abstract

The invention provides a preparation method for a chalcopyrite flotation agent. The preparation method comprises the steps that erucic acid, maleic acid and low density polyethylene are firstly mixed and then stirred for 10-20 min at the temperature of 50 DEG C-60 DEG C, the stirring frequency is 5,000-10,000 turns / minute, and a first mixture is obtained; butyl xanthate, glycol ether, ethyl alcohol, a coupling reagent KH550 and water are added into the first mixture, stirring is carried out for 10-20 min at the temperature of 35 DEG C-45 DEG C with the frequency of 6,000-12,000 turns / minute, and a second mixture is obtained; and finally sodium dodecyl benzene sulfonate is added into the second mixture, and stirring is carried out for 10-20 min at the temperature of 30 DEG C to 40 DEG C with the frequency of 5,000-10,000 turns / minute. The preparation method is easy to operate, the obtained chalcopyrite flotation agent is good in dispersing and capturing effect and selectivity, and copper in low-grade chalcopyrite can be efficiently selected out in a flotation manner.

Description

technical field [0001] The invention relates to the field of flotation agents, in particular to the field of chalcopyrite flotation agents. Background technique [0002] Chalcopyrite is mainly copper-iron sulfide, which also contains trace amounts of gold, silver and other substances. It is the most widely distributed type of copper ore and the most important raw material for copper smelting. It is concentrated in Sichuan and Yunnan. There are relatively mature, stable and efficient technologies for extracting copper from ores, but there is still a lot of room for improvement in the existing technologies regarding the full extraction of copper from low-grade chalcopyrite ores. Contents of the invention [0003] The purpose of the present invention is to propose a method for preparing a flotation agent with good dispersion and collection effects and good selectivity, especially for low-grade chalcopyrite flotation. [0004] Technical scheme of the present invention is as f...
