Low-temperature-resistant zinc oxide ore flotation composite reagent and preparation method and application thereof

Abstract

The invention relates to a low-temperature-resistant zinc oxide ore flotation composite reagent and a preparation method and application thereof. The composite reagent comprises a composite regulatorand a composite collecting agent, wherein the composite regulator is formed by mixing sodium hexametaphosphate, starch and sodium humate according to a weight ratio of (5-7): (3-6): (1-3), and the composite collecting agent is formed by mixing octadecylamine, glacial acetic acid, sodium benzohydroxamic acid and waste engine oil according to a weight ratio of (5-8): (5-8): (1-3): (1-3). By using the two composite beneficiation reagents, desliming is not needed in the process of flotation, so the recovery of fine-grained zinc oxide is enhanced, and the beneficiation recovery rate of zinc oxide ore can be improved by 5-15%.

AI Technical Summary

Benefits of technology

This patented technology combines certain technical features that make them more effective than previous methods like separate precipitation or separation processes alone. One advantage being this combination allows for better removal of unwanted elements from raw materials while still allowing for efficient floatage of finely grainy material (ZnO). Another benefit provided through the use of specific combinations of these components results in improved efficiency when treating high-quality Zinc oxides such as sintered pellets. Additionally, the manufacturing process does not require expensive chemicals, reducing environmental impact on disposal. Overall, this method simplifies the treatment process and saves resources compared to current technologies.

Problems solved by technology

The technical problem addressed in this patents relates to improving the efficiency and stability of producing pure zirconia from zincoal during conventional methods for removing impurities such as iron and manganese beforehand. This can result in decreased cost savings over current processes due to improved purity levels achieved through efficient removal of these unwanted materials while maintaining stable performance under different conditions.
