Problems solved by technology

Due to the different floating speeds of various copper ores, it is difficult to simultaneously and effectively control the grade and recovery rate.
[0003] Flotation agents such as xanthate, thiophosphate and mercaptan, thiamine ester, xanthate, black drug ester and xanthate are the dominant collectors in the current copper-sulfur ore flotation process. , but in the actual beneficiation, the results often fail to meet the design requirements, the separation of copper and sulfur is not ideal, the sulfur content in copper concentrate products exceeds the standard, and the recovery rate of copper concentrate is low, resulting in a waste of mineral resources, so the separation of copper and sulfur Collectors still need to be developed, and the development of a selective collector that can address various requirements is necessary

Abstract

The invention discloses a flotation collecting agent for copper sulfide ore, and belongs to the technical field of mineral processing. The flotation collecting agent comprises the following raw materials of, by weight, 8-10 parts dialkyl phosphate, 1-2 parts of octyl phenol polyoxyethylene, 2-3 parts of polyoxyethylene stearate, 1-2 parts of triethylene tetramine, 3-5 parts of o-hydroxybenzoic acid and 4-5 parts of activating agents. The collecting agent has the double properties of collecting and foaming, collecting performance is good, the selectivity is good, the mineral floating speed is fast, the flotation foam is stable, the concentrate grade and the recovery rate can be effectively improved, and the collecting agent is an ideal selective collecting agent for the copper sulfide ore.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a flotation collector for copper sulfide ore. Background technique [0002] With the rapid development of the national economy and the continuous development and utilization of mineral resources, the properties of ores have become complex and diverse, and many conventional flotation reagent methods are becoming more and more difficult to adapt to the changes in ore properties. Low-grade complex copper-sulfur ore is one of them, especially complex copper-sulfur ore containing multiple copper ores. Due to the different floating speeds of various copper ores, it is difficult to simultaneously and effectively control the grade and recovery rate. [0003] Flotation agents such as xanthate, thiophosphate and mercaptan, thiamine ester, xanthate, black drug ester and xanthate are the dominant collectors in the current copper-sulfur ore flotation process. , but in the actual ...
