Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand processing, in particular to a high-purity quartz sand continuous flotation device. Background Art

[0002] Flotation is an essential part of the high-purity quartz sand beneficiation and purification process. At present, the industry generally uses single-slot flotation machine equipment for flotation operations. By adding flotation agents, impurities in quartz, such as mica, feldspar, clay minerals, iron-containing minerals, etc., are floated out, so as to achieve the purpose of separation and purification. The flotation process is usually: inject water into the flotation machine → start stirring → add the raw sand to be floated → add flotation agents → start flotation after the agent and the ore sample fully react → scrape out the tailings → release the flotation wastewater after the flotation is completed → inject pure water to wash the flotation concentrate → release the flotation concentrate and dehydrate it. Conventional flotation processes are generally discontinuous, and each step requires manual observation and manual operation, which not only affects the stability of the product, but also increases the workload of the operator. In addition, the flotation agents used by most manufacturers are relatively single and poorly targeted, and cannot be adjusted accordingly according to the different types of mineral impurities, resulting in incomplete flotation and the quartz sand grade not meeting the quality requirements.
