Flotation operation principle

There are three general principles for flotation operation: one is to operate according to the quantity and quality requirements of the product; the other is to operate according to the change of ore properties; the third is to maintain the relative stability of the flotation process, because only the stability of the process can be achieved. The process indicators are stable. Generally, the ore properties are relatively stable or have little change, and various operating conditions and process indicators should be kept as stable as possible. However, if the nature of the ore changes greatly and the original operating conditions are not appropriate, causing the index to drop, it is necessary to change various operating conditions.

Based on years of production experience, China's flotation plant has summed up the “three-degree and one-standard” operation method. The so-called "three degrees", that is, accurately control the fineness of grinding, the concentration of flotation (mass fraction) and the pH of the pulp in the production process; "one quasi", that is, the flotation agent is given. Some flotation plants have also summarized some specific operational essentials in production practice, such as the "three-time, four-standard, four-good, two-time, one-to-no-action" operation method. "Three Qin": diligently observe changes in foam, diligently measure concentration, and diligently adjust; "four quasi": the formulation and addition of the drug is accurate, the grade change is accurate, the cause of the change is accurate, and the amount of foam scraping is accurate. "Four good": Flotation and drug station are well connected, flotation and grinding are well connected, flotation and sand pump are well connected, mixed flotation and separation flotation are well connected; "two timely": The problem has been studied in a timely manner, and the problem-solving has been dealt with in a timely manner; "One does not move": the operation of the flotation machine gate is not turbulent, and these operational experiences have also achieved good results. Of course, these experiences are obtained under specific conditions. In actual application, they should be adopted according to the actual production of the factory.
