Problems solved by technology

[0003] However, for copper-cobalt ores containing more carbonaceous matter, only by adding xanthate collectors and No. 2 oil for separation, the sorting performance is very poor, or even no sorting performance, because The particles are small and have a large specific surface area, and they are non-selectively adsorbed on the mineral surface, which deteriorates the flotation process and seriously affects the flotation of copper-cobalt ore

Abstract

The invention discloses a flotation method for carbonaceous copper-cobalt ore. The flotation method includes firstly, performing ore grinding on copper-cobalt core raw materials, adding lime during ore grinding, and grinding the ore until the ore is -0.074mm in size and accounts for 70%-80%; adding water and preparing ore pulp until concentration of the ore pulp reaches 25%-30%; adding a regulating agent, a collecting agent and a foaming agent again for ore pulp preparation; performing flotation, including two-time rougher flotation, two-time scavenging and three-time concentration, on the ore pulp subjected to ore pulp preparation; adding one or more of the regulating agent, the collecting agent and the foaming agent during each operation according to needs to finally obtain copper-cobalt concentrates and tailings. The flotation method is simple in procedure, convenient to control, high in separation efficiency and good in index, and the obtained copper-cobalt concentrates have good quality.

Description

technical field [0001] The invention relates to the technical field of mineral smelting, in particular to a method for flotation of carbonaceous copper-cobalt ore. Background technique [0002] At present, the beneficiation method of copper-cobalt sulfide ore is mainly flotation method, the beneficiation method of copper-cobalt oxide ore and mixed ore is mainly flotation method, and a few use ore washing, dense medium beneficiation or a combination of flotation method. The flotation method generally uses xanthate collectors and No. 2 oil for separation, which is suitable for the separation of copper-cobalt ores mainly composed of silicate gangue minerals and copper-cobalt ores mainly composed of carbonate gangue minerals . [0003] However, for copper-cobalt ores containing more carbonaceous matter, only by adding xanthate collectors and No. 2 oil for separation, the sorting performance is very poor, or even no sorting performance, because The particles are small and have ...
