New technology of red iron ore beneficiation 1

The characteristics of the continuous grinding, weak magnetic → strong magnetic → anion reverse flotation process are as follows:

Red iron ore:

1.Have a good process flow structure

Judging from the current status of red iron ore beneficiation in my country, strong magnetic separation is one of the most effective means of throwing tails, and anion reverse flotation is one of the most effective means to improve concentrate grade. At the same time, the combination of strong magnetic separation and anion reverse flotation is conducive to the realization of the complementary advantages of the technological process. This is not only reflected in the quality and tail reduction of the two processes itself, but also in that strong magnetic separation can provide good separation for reverse flotation Conditionally.

2.Convenient for production and stable operation

The continuous grinding process directly grinds the ore to a higher level of monomer dissociation, and uses a strong magnetic separator to remove the sludge and discard the tail. It not only prepares higher-grade selected materials for the anion reverse flotation process, but also eliminates the original. The influence of sludge and secondary sludge on the anion reverse flotation process, and the strong magnetic separation itself has good stability. Anion reverse flotation itself provides better candidates for its strong magnetic separation, and it also has better stability. Therefore, after the continuous grinding, weak magnetic → strong magnetic → anion reverse flotation process has controlled the final grinding particle size, the process has good stability and strong adaptability to ore, which is convenient for stable production and operation.

3.It has good process operation characteristics

Continuous grinding, weak magnetic → strong magnetic → anion reverse flotation process due to its high concentrate grade, low flotation temperature, suitable for pipeline transportation, good separation effect, good flotation foam stability, and good fluidity. Features, easy to control in production operations, which is conducive to the stability of production indicators. Of course, this process has the problem of high beneficiation cost due to the fine grinding particle size.
