Abstract

Abstract

The majority of hematite flotation collectors currently utilized in China exhibit poor water solubility due to their long hydrocarbon chains. Consequently, the slurry frequently necessitates heating during flotation operations, which increases energy consumption and costs in processing plants. Developing hematite collectors that are effective at normal and low temperatures is one of the pivotal approaches to optimizing the hematite flotation reagent system enhancing efficiency, and reducing consumption, especially within the framework of the "dual carbon" goals. By meticulously analyzing the recent research findings on new normal and low-temperature collectors and compound collectors in the hematite flotation system, the characteristics of reagents conducive to normal and low-temperature flotation processes were elucidated, focusing on the active organic groups and their impact on production indicators. The objective is to summarize and expand upon the design ideas for new types of normal and low-temperature hematite flotation collectors, promoting the research, development, and application of these reagents in hematite flotation processes and gradually achieving enhanced efficiency and reduced consumption.
