Description

Technical Field

[0001] The invention relates to the technical field of quartz processing, and more particularly to a flotation device for processing quartz ore particles. Background Art

[0002] Quartz is a widely distributed non-metallic mineral. Due to its excellent chemical stability, mechanical strength and thermal stability, it has important application value in glass, ceramics, optical materials and electronic industries. However, natural quartz ore is usually accompanied by a variety of impurity minerals, such as feldspar, mica, iron minerals and other non-metallic minerals, which affect its purity and industrial application performance. Therefore, in order to meet the requirements of high-purity quartz products, efficient and fine sorting and purification of quartz ore has become an important research and production demand.

[0003] Flotation technology is an important method to separate target minerals from mixed ores by utilizing the differences in physical and chemical properties of mineral surfaces. This technology adds flotation agents to the slurry to change the hydrophobicity of mineral particles, allowing the target mineral to adhere to the surface of bubbles and float up, thereby achieving separation from other minerals.

[0004] After searching, a Chinese patent (Announcement No.: CN109127157B) discloses a quartz sand flotation machine, which inputs gas into the stirring tube through the gas pipe, and then transports the gas into the flotation liquid through the air outlet on the stirring paddle, so that the flotation effect of the quartz sand is better. At the same time, since the stirring paddle rotates continuously with the stirring tube, the gas transported by the stirring paddle to the flotation liquid is more uniform, so that the flotation effect of the quartz sand is further improved. The blowing device is installed on the inner side wall of the flotation tank, and the blowing device is set corresponding to the notch.

[0005] In the prior art, when impurities are removed, if a single removal method is used, the quality of impurity removal is poor, and some quartz particles have a small specific gravity and a smooth surface, which easily leads to low separation efficiency during the flotation process.
