In the industrial flotation machine work, it is inevitable that the ore properties in the flotation circuit of the flotation machine are changed.
Therefore, there must be ways to observe and adjust for this change. Changes in the relationship of mineral crystal structure may have an important impact on the degree of dissociation and the optimal grinding fineness.
It is a common phenomenon for flotation machine equipment experts to analyze changes in the proportion of symbiotic minerals, which are largely adjusted by mixing the ore before and after crushing.
When the flotation machine equipment gives a high grade of minerals, it is relatively easy to produce high-mineral foam products and high-grade lectures; when the grade of the ore is low, it is difficult to maintain the stability of the foam. At this time, if the flotation machine The flotation cell and chute have the appropriate flexibility and may require the flotation cell of one of the final selected flotation machines to be classified into a lower grade operation.
When the ore is not only taken from a single location, the proportion of different minerals in the ore fed to the plant will inevitably fluctuate, and the observed change may be aggravated by local oxidation of the ore.
This may be caused by geological changes or not timely delivered mine mineral mining area since the plant after crushing.
Ore is often oxidized when stored in storage yards or warehouses for extended periods of time. It is therefore necessary to determine the degree of oxidation of a particular ore to ensure that storage times are much less than the critical period of oxidation.
The oxidized ore becomes soft due to the decomposition of the crystal lattice, becomes more difficult to react with the collector , and is more likely to undergo over-grinding.
