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 it is 1.0%, the recovery rate of nickel is only 55-60%, 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

Embodiment Construction

[0016] In the following examples, only the parts by weight of the raw materials are changed, and the method of preparing the collector remains unchanged. In order to more intuitively describe the influence of the changes in the weight of raw materials in different embodiments on the beneficiation index, a single copper ore was selected for the beneficiation test under the same conditions, and the grade and recovery rate of the copper and nickel crude concentrates were listed respectively. The change in the beneficiation index of nickel coarse concentrate reflects the performance of the collector synthesized by different raw material weight parts. The high grades of the copper and nickel crude concentrates indicate that the collectors have strong selection performance; the high recovery rate of the copper and nickel crude concentrates indicates that the collectors have strong collecting performance.

[0017] The specific numerical values ​​of Example 1 to Example 5 are shown in Ta...

Abstract

The invention relates to a copper-nickel sulphide ore catching agent, namely a J622 catching agent. The copper-nickel sulphide ore catching agent is prepared by the following raw materials in parts by weight: 30-60 parts of alkyl xanthate propionitrile ester, 10-30 parts of oil No.2, 10-20 parts of black catching agent No.25, 5-15 parts of amino propionitrile, and 5-15 parts of black catching agent acid. The raw materials are mixed fully and stirred uniformly to prepare the copper-nickel sulphide ore catching agent. The copper-nickel sulphide ore catching agent has catching and foaming doubleattributes, and is good in selectivity, high in catching capability and ore flotation speed, and stable in flotation foam, so that the grade and the recovery rate of the concentrate can be effectively improved; and therefore, the copper-nickel sulphide ore catching agent is a very ideal selective catching agent for copper-nickel ores.

Description

Technical field [0001] The invention relates to a flotation agent used for ore dressing in the non-ferrous metal industry, in particular to a copper sulfide nickel ore collector. Background technique [0002] At present, the domestic copper-nickel ore beneficiation generally adopts the method of using xanthate and black medicine, xanthate and foaming agent or xanthate and ester collector together. There are few kinds of medicines, and there is not much room for choice. The combination of ethyl yellow medicine and butyl ammonium black medicine is the most widely used as a mixed collector. Conventional flotation reagents have a strong ability to collect metal minerals, but they have poor selectivity. There have always been problems such as low nickel recovery, large fluctuations in indicators, and reduced recovery rates affected by temperature in winter. When the raw ore contains 0.5~ At 1.0%, the nickel recovery rate is only 55-60%, the flotation effect is not ideal, the resource...
