Abstract

The invention relates to the technical field of linnaeite flotation, in particular to a flotation separation reagent system for linnaeite. The system comprises an adjusting agent, a foaming agent, a cobalt collecting agent and an inhibitor for low-cobalt sulfide and aluminosilicate gangue minerals. The cobalt collecting agent comprises sodium ethylxanthate, tert-dodecanethiol and sodium diethyldithiocarbamate, the inhibitor comprises sodium hydroxide, sodium thiosulfate and sodium thioglycolate, and the foaming agent comprises methyl carbitol. The invention further discloses application of the flotation separation reagent system in beneficiation enrichment of cobalt sulfide rough concentrate obtained in the flotation desulfurization process of linnaeite, especially ilmenite. According to the method, the defect that sulfur and cobalt resources in the vanadium titano-magnetite in the Panzhihua region cannot be effectively recycled in the prior art is overcome, and the effects of effectively improving the utilization rate of the sulfur and cobalt resources in the Panzhihua ore and effectively separating the cobalt concentrate from the sulfur concentrate are achieved.

Description

technical field [0001] The invention relates to the technical field of flotation of sulfur cobalt ore, in particular to a flotation separation agent system of sulfur cobalt ore and its application. Background technique [0002] Panzhihua area is rich in mineral resources. In addition to iron, vanadium and titanium, the ore also contains a large amount of sulfur and cobalt. At present, among the approximately 7 billion tons of vanadium-titanium magnetite that has been proven, the associated important strategic metal cobalt reserves are more than 1.55 million tons, which has a relatively high comprehensive utilization value. [0003] As the industry requires that the sulfur content in titanium concentrate, the main product of the titanium beneficiation plant, be below 0.2%, therefore, in the configuration of the titanium beneficiation process in Panzhihua area, it is necessary to carry out the flotation desulfurization process, that is, to desulfurize the crude titanium concen...
