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

[0009] Mix 5 parts of butyl xanthate, 8 parts of butyl ammonium black medicine, 1 part of lauric acid, 1 part of myristic acid, 3 parts of tall oil, and 10 parts of ethylene glycol ether. Stir at a stirring frequency for 30 minutes, then add 5 parts of ethanol, 1 part of coupling agent KH550, and 30 parts of water. After heating up to 45°C, stir at a stirring frequency of 6000 rpm for 10 minutes, and finally add 1 part of dodecylbenzenesulfonate Na2SO4, cooled to 40°C, and stirred at a stirring frequency of 5000 rpm for 10 minutes to obtain the mineral flotation agent.

Embodiment 2

[0011] Mix 7 parts of butyl xanthate, 10 parts of butyl ammonium black medicine, 5 parts of lauric acid, 5 parts of myristic acid, 7 parts of tall oil, and 15 parts of ethylene glycol ether. Stir at a stirring frequency of 20 minutes, then add 10 parts of ethanol, 3 parts of coupling agent KH550, and 50 parts of water. After heating up to 35°C, stir at a stirring frequency of 12000 rpm for 20 minutes, and finally add 5 parts of dodecylbenzenesulfonate Na2SO4, cooled to 30°C, and stirred at a stirring frequency of 5000 rpm for 20 minutes to obtain the mineral flotation agent.

Abstract

The invention provides a preparing method for a mineral floatation agent. The preparing method comprises the following steps that butyl xanthate, ammonium dibutyl dithiophosphate, lauric acid, myristic acid, tall oil and glycol ether are mixed at the temperature ranging from 30 DEG C to 40 DEG C and stirred for 20-30 min at the stirring frequency ranging from 5,000 turns / min to 10,000 turns / min; then, ethanol, a coupling agent KH550 and water are added, and stirring is conducted for 10-20 min at the temperature ranging from 35 DEG C to 45 DEG C at the frequency ranging from 5,000 turns / min to 10,000 turns / min; lastly, sodium dodecyl benzene sulfonate is added, and stirring is conducted for 10-20 min at the temperature ranging from 30 DEG C to 40 DEG C at the frequency ranging from 5,000 turns / min to 10,000 turns / min. The preparing method is simple in operation, the obtained mineral floatation agent is good in dispersing and collecting effect and selectivity, and especially copper in low-grade copper pyrites can be efficiently selected out through flotation.

Description

technical field [0001] The invention relates to the field of mineral flotation agents, in particular to the field of brass 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 object of the present invention is to propose a preparation method of a mineral flotation agent with good dispersion and collection effects and good selectivity, especially for low-grade chalcopyrite flotation. [0004] Technical scheme of the present inventio...
