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 for preparing the collector remains unchanged. In order to more intuitively describe the impact of changes in the weight of raw materials in different embodiments on the beneficiation index, a single copper ore is selected to carry out the beneficiation test under the same conditions, and the grades and recovery rates of copper and nickel rough concentrates are listed respectively. The change of beneficiation index of nickel rough concentrate reflects the performance of collectors synthesized with different weight parts of raw materials. The high grade of copper and nickel rough concentrate indicates that the collector has strong selectivity; the high recovery rate of copper and nickel rough concentrate indicates that the collector has strong collection performance.

[0017] The concrete numerical value of embodiment 1 to embodiment 5 is shown in table 1.

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 reagent used for mineral processing in the non-ferrous metal industry, in particular to a collector for copper-nickel sulfide ore. 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 ~ 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 environm...
