Description

Technical Field

[0001] This utility model relates to the field of flake graphite processing, and in particular to a high-efficiency flotation impurity collection device for flake graphite. Background Technology

[0002] Flake graphite is an important industrial raw material, widely used in metallurgy, chemical industry, electrical industry, and defense. However, during its mining and processing, various impurities are often introduced, affecting its purity and application performance. Flotation technology is a common method for treating mineral impurities, based on the differences in mineral surface properties to separate valuable minerals from gangue minerals. Flotation columns typically use an external air supply system to inject microbubbles into the pulp. The pulp flows downwards, while the bubbles move upwards from the bottom. In this process, hydrophobic flake graphite more easily collides with and adheres to the rising bubbles. As the mineralized bubbles rise to the pulp surface, they aggregate to form a stable froth layer. This froth layer is rich in the target mineral and can be scraped off from the pulp surface using mechanical devices, thus achieving separation from impurities.

[0003] Temperature has a significant impact on the flotation of flake graphite, mainly affecting flotation efficiency by altering mineral surface properties, reagent activity and solubility, bubble stability, and pulp viscosity. Appropriately increasing the temperature can enhance the hydrophobicity of graphite and the effectiveness of reagents, promoting the flotation of fine-grained graphite. However, existing flotation columns generally do not include temperature control structures. Utility Model Content
