Embodiment 1

[0016] A certain copper ore in Jiangxi Province, the original ore contains 0.48% copper, the copper minerals in the ore are mainly chalcopyrite, the iron minerals are mainly pyrite and pyrrhotite, and the gangue minerals are talc, quartz, serpentine and Mica. Grind the copper ore to -0.074mm and the content is 78%, transfer the ground pulp to the flotation tank, add 900g / t sodium carbonate, 1500g / t combination inhibitor TYZ01, 180g / t combination collector TBS02, 20g / t No. 2 oil slurry, and then roughing, to obtain roughing tailings and roughing concentrate, add 60g / t and 30g / t combined collector TBS02 to the roughing tailings for two sweeping Concentration operation, to obtain the final tailings, return to the roughing for the first sweep, and return to the first sweep for the second sweep; add 600g / t combined inhibitor TYZ01 to the coarse concentrate obtained by roughing for the first For the second beneficiation, the obtained concentrate is added with 250g / t combined inhibi...

Embodiment 2

[0023] A certain copper ore contains 0.55% copper in the raw ore. The copper minerals in the ore are mainly chalcopyrite, the iron minerals are mainly pyrite, and the gangue minerals in the ore are mainly talc, quartz, mica, and feldspar. Grind the copper ore to -0.074mm and the content is 65%, transfer the ground pulp to the flotation tank, add 500g / t sodium carbonate, 600g / t combined inhibitor TYZ01, 120g / t combined collector TBS02 , 20g / t No. 2 oil for roughing to get roughing tailings and roughing concentrate, add 60g / t and 30g / t combined collector TBS02 to the roughing tailings for two sweeping operations to get the final For the tailings, return to the rougher for the first sweep, and return to the first sweep for the second sweep; add 300g / t combined inhibitor TYZ01 to the coarse concentrate obtained by the rougher for the first concentration, and get Add 100g / t combined inhibitor TYZ01 to the concentrated ore for the second beneficiation to obtain the final concentrate...

Abstract

The invention relates to a beneficiation method for improving the ore dressing recovery percentage of copper sulfide ore hard to dispose. By applying the method, flotation separation of copper sulfide mineral from hydrophobic silicate gangue talc and ferric sulfide mineral pyrite can be realized, and the preparing technical indexes of copper sulfide mineral can be improved. The method comprises the operations of ore grinding, size mixing, rougher flotation, scavenging and selection. According to the invention, a combined inhibitor TYZ01 has a selective inhibiting effect on talc and pyrite and cannot affect the flotation of copper pyrites, and a combined collecting agent TBS02 has strong collecting capability on copper pyrites; by using the two combined reagents, efficient utilization of copper sulfide mineral containing hydrophobic silicate gang and pyrite can be realized; proved by practices, by using the beneficiation method disclosed by the invention, good selection indexes can be obtained; and the adopted reagents, calcium lignosulfonate and Arabic gum, are organic macromolecule reagents, thus being easy to degrade and having no pollution to the environment.

Description

technical field [0001] The invention relates to a beneficiation method for improving the recovery rate of refractory copper sulfide ore dressing. By using the method, the flotation separation of copper sulfide minerals, hydrophobic silicate gangue talc and iron sulfide mineral pyrite can be realized, and the sulfide minerals can be improved. Copper ore beneficiation technical indicators. Background technique [0002] Copper resources are one of the most widely used important basic raw materials in the development of the national economy. They are widely used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields. It is second only to aluminum in the consumption of non-ferrous metal materials in my country. my country is a country with large copper resources, but in recent years, the growth rate of copper consumption has been significantly faster than the growth rate of production. With the acceleration of in...
