What should I do if the scheelite flotation selected tailings is too high?

Scheelite flotation is a commonly used ore beneficiation method, but in the actual production process, sometimes the concentration of tailings is too high. This will lead to a reduction in the scheelite recovery rate and affect the economic benefits of the ore. This article will discuss the reasons why the scheelite flotation concentration tailings are too high and how to optimize the process to improve the recovery rate.

Cause analysis: Possible reasons for excessively high selected tailings

1. Changes in ore composition: During the scheelite flotation process, changes in ore composition are one of the common causes of excessively high concentration of selected tailings. It may be that the impurity content in the ore increases or the composition of the ore itself changes, resulting in a decrease in flotation effect.

2. Improper operating parameters: Improper setting of operating parameters may also lead to excessively high selected tailings. For example, improper input of chemicals, too fast or too slow stirring speed, improper adjustment of flotation machinery, etc. may affect the separation effect of ore.

3. Equipment wear and failure: Wear and failure of equipment may also cause the refined tailings to be too high. For example, the wear and tear of the flotation machinery leads to a decrease in the separation effect, and equipment failure leads to unstable operation, which will affect the improvement of the recovery rate.

Optimizing your process: ways to improve recovery rates

1. Ore pre-treatment: Through ore pre-treatment processes, such as ore grinding, ore leaching, etc., the impurity content in the ore can be reduced and the production of refined tailings can be reduced. At the same time, the grinding fineness and leaching conditions should be reasonably controlled to improve the exposure and floatability of scheelite.

2. Optimization of operating parameters: According to the actual ore characteristics, reasonably set operating parameters, such as the type and input amount of chemicals, stirring speed, adjustment of bubble generator, etc. By optimizing operating parameters, the separation effect of ore is improved and the content of selected tailings is reduced.

3. Equipment maintenance and updates: Regularly maintain and inspect flotation equipment to ensure normal operation of the equipment. Timely replace severely worn parts, repair equipment failures, and improve equipment stability and reliability. At the same time, based on actual needs, consider updating more efficient flotation equipment to improve the recovery rate of ore.

When the scheelite flotation concentration of tailings is too high, it is necessary to comprehensively analyze the reasons and take corresponding optimization measures. Through methods such as ore pretreatment, operating parameter optimization, and equipment maintenance updates, the recovery rate of scheelite can be increased and the content of selected tailings can be reduced, thereby achieving higher economic benefits.
