AI Technical Summary

Problems solved by technology

Conventional flotation reagents have a strong ability to collect metal minerals, but their selectivity is poor. There have always been problems such as low nickel recovery rate, large index fluctuations, and lower recovery rate affected by temperature in winter. When the raw ore contains 0.5- At 1%, the recovery rate of nickel is only 50-60%, the flotation effect is not ideal, the resource utilization rate is low, the consumption is large, the environmental pollution is serious, and it is difficult to realize economical, efficient and clean development and utilization of copper-nickel ore resources

Abstract

The invention relates to the technical field of fine chemical engineering and concretely a high efficient copper sulphide ore collector formed by the following components according to a weight ratio, isobutyl allyl sulphur taking up 20 to 50, sulphur nitrogen nitrile taking up 20 to 30, No.2 oil 10 to 20 and propyl group xanthogenic acid propionitrile 10 to 15. The sulphide ore collector is high efficient and environment-protective.

Description

technical field [0001] The invention relates to the technical field of fine chemical industry, in particular to a high-efficiency copper sulfide collector. Background technique [0002] At present, the domestic copper-nickel ore beneficiation production generally adopts the combined use of xanthate and black medicine, xanthate and foaming agent or xanthate and ester collector. The combination of dixanthate and butyl ammonium black drug is the most widely used as a mixed collector. Conventional flotation reagents have a strong ability to collect metal minerals, but their selectivity is poor. There have always been problems such as low nickel recovery rate, large index fluctuations, and lower recovery rate affected by temperature in winter. When the raw ore contains 0.5- At 1%, the recovery rate of nickel is only 50-60%, the flotation effect is not ideal, the resource utilization rate is low, the consumption is large, the environmental pollution is serious, and it is difficul...
