Highly efficient beneficiation reagent for copper-nickel polymetallic sulphide ores

Abstract

The invention aims to provide a highly efficient beneficiation reagent for copper-nickel polymetallic sulphide ores. According to the invention, the reagent is prepared from the following raw materials by mass: 0.05-0.40 parts of diesel, 0.80-1.30 parts of liquid butyl ammonium aerofloat, 0.30-0.80 parts of isopropyl ethylthionocarbamate and 0.20-0.60 parts of sulfur nitrogen nitrile ester. According to the invention, the application of the reagent in beneficiation of the copper-nickel polymetallic sulphide ores can greatly reduce the content of magnesium oxide in the copper-nickel concentrate ores and significantly increase the recovery rate of metals from the copper-nickel polymetallic sulphide ores so as to realize sufficient, efficient and comprehensive utilization of the existing copper-nickel mineral resources, extend the service life of mines and create good economic benefits and social benefits.

Description

technical field [0001] The invention relates to a beneficiation agent used in the beneficiation process of copper-nickel polymetallic sulfide ore, in particular to a beneficiation agent suitable for complex refractory copper-nickel polymetallic sulfide ore. Background technique [0002] Mineral resources are an important material basis for economic construction and social life. At present, due to the rapid development of the national economy, the demand for mineral resources has been in a state of rapid and continuous growth. With the large-scale mining and utilization, my country's important non-ferrous mineral resources are increasingly depleted and complicated. Based on the current situation of poor, miscellaneous and difficult important non-ferrous mineral resources, all non-ferrous enterprises need to seek strong harvesting power and good selectivity. It is a high-efficiency ore-dressing agent with less dosage, less environmental pollution, and can significantly improve...

Problems solved by technology

[0003] For copper-nickel polymetallic sulfide ores, the traditional commonly used collectors mainly include: xanthates (such as butyl xanthate, amyl xanthate, etc.), thiophosphates (such as butyl ammonium black medicine, etc.) ), these collectors, such as xanthate, have strong collecting power, but their selectivity is poor, and the quality of concentrate products is low; although black powder has good selectivity, the recovery rate of main metals in the sorting process is often not good. ideal

The emergence and application of esters (such as thiourethane, xanthate, etc.) have greatly improved the mineral processing technical indicators compared with the above-mentioned agents, but for chlorite containing high calcium and magnesium and easy to buoyant and muddy , complex and refractory copper-nickel polymetallic sulfide ore with high serpentine, it is difficult to obtain satisfactory separation technical indicators by using the above-mentioned reagents, which has resulted in the inability of efficient and comprehensive recycling of strategic non-ferrous metals in my country's bulk shortage, resulting in huge losses waste of resources
