Problems solved by technology

Sulfidation flotation is a commonly used method in the development and utilization of copper oxide ore. Usually, sodium sulfide is pre-sulfurized, and then high-grade xanthate or other sulfide ore collectors are used for flotation. However, in the prior art, One of the biggest disadvantages of this type of collector is the low recovery rate

Abstract

The invention discloses a preparation method of a collecting agent for flotation of copper oxide ore. According to the method, firstly, ammonium dialkyldithiophosphate and 2-carboxymethyl thioether-5-hydrocarbonylbenzimidazole are mixed in advance in certain proportion, a proper amount of ethanol is added to serve as a solvent and sufficiently mixed, a small quantity of diesel oil additives are added to the mixture and further mixed, and the collecting agent is prepared. The collecting agent prepared with the method has the advantages of high collecting capacity and small usage quantity, can effectively replace conventional collecting agents such as xanthate and the like during sulfuration flotation and contributes to increase of the recovery rate of copper oxide.

Description

technical field [0001] The invention relates to the technical field of flotation separation of copper oxide ore, in particular to a method for preparing a collector for flotation of copper oxide ore. Background technique [0002] At present, copper is a very important metal in the national production process. It has good ductility and electrical conductivity, and is easy to form alloys with various elements. It is widely used in electronics, construction, national defense, machinery, light industry and other industries. The main sources of copper are copper sulfide ore and copper oxide ore. However, with the large consumption of copper due to economic and social development, the reserves of industrially easy-to-select copper sulfide ore are decreasing sharply, and it is gradually difficult to meet the needs of my country's rapid economic development. Therefore, copper oxide The development of the mine has gradually attracted people's attention. Copper oxide ore resources acc...
