Problems solved by technology

[0004] However, most of the flotation collectors in the prior art are developed solely for sulfide minerals or oxidized minerals in non-ferrous metal ores, and cannot effectively collect sulfide minerals or oxidized minerals at the same time, especially for those containing rich sulfide and oxidized minerals. The mixed non-ferrous metal ores of minerals are difficult to recycle, resulting in waste of resources

Embodiment 1

[0036] Preparation of N,N-dibutyldithiocarbamate acetone oxime:

[0037] Add 15.63 parts of sodium N,N-dibutyldithiocarbamate to a mixed solution of 6.72 parts of chloroacetone oxime and 36 parts of methanol at a temperature of 20°C under stirring, and then stir and react at 20°C for 2 hours. After filtration, the filtrate was distilled under reduced pressure and washed with water to obtain a white solid, which was N,N-dibutyldithiocarbamate acetone oxime. The yield was 95%. Product infrared characterization such as figure 1 shown.

Embodiment 2

[0039] Preparation of N,N-dibutyldithiocarbamate acetaldoxime:

[0040] Add 15.63 parts of sodium N,N-dibutyldithiocarbamate to a mixed solution of 4.68 parts of chloroacetaldoxime and 36 parts of methanol at 20°C under stirring, and then stir and react at 20°C for 2 hours. After filtering, the filtrate was distilled under reduced pressure and then washed and dried to obtain a dark red oily liquid, namely N,N-dibutyldithiocarbamate acetaldoxime. The yield was 96%. Product infrared characterization such as figure 2 shown.

Embodiment 3

[0042] Preparation of O-isobutyl xanthate acetone oxime

[0043] Add 17.2 parts of sodium isobutyl xanthate to a mixed solution of 10.75 parts of chloroacetone oxime and 36 parts of methanol at a temperature of 20°C under stirring, and then stir and react at 20°C for 2 hours. After filtering, the filtrate was distilled under reduced pressure and washed with water to obtain a white solid, which was O-isobutyl xanthate acetone oxime. The yield was 90%. Product infrared characterization such as image 3 shown.

Abstract

The invention discloses a nonferrous metal ore flotation collecting agent with a mercapto-oximido structure and the application thereof. The flotation collecting agent has a mercapto group and an oximido group and is used as nonferrous metal ore flotation collecting agent for flotation separation, so nonferrous metallic minerals in nonferrous metal ore can be highly efficiently recycled. Thus, it is achieved that one kind of flotation collecting agent is capable of simultaneously recycling sulfide minerals and oxide minerals in nonferrous metal ore, and recycling rate of nonferrous metal minerals in nonferrous metal ore is greatly increased. The nonferrous metal ore flotation collecting agent is especially suitable for recycling of nonferrous metal of mixed minerals containing sulfide minerals and oxide minerals simultaneously, recycling processes of nonferrous metal are simple, highly practical and practicably, and industrially application requirements are met.

Description

technical field [0001] The invention relates to a nonferrous metal ore flotation collector with a novel structure of mercapto-oxime group and its application in nonferrous metal mineral flotation, which belongs to the technical field of metal mineral flotation. Background technique [0002] Flotation is the most important method to recover metal minerals from metal ores, and flotation collector is one of the key technologies for the separation and extraction of valuable mineral components by flotation. The adsorption of flotation collectors on the mineral surface directly affects the hydrophobicity of the mineral surface and the flotation process. The development of new flotation collectors and the improvement of the hydrophobicity of mineral particles play an important role in improving the comprehensive recovery rate of metals. [0003] Mercapto compounds are good collectors for sulfide minerals, and oxime compounds have good collection performance for oxidized minerals. ...
