Therefore, in the process of popularization and application of magnetic separator - reverse flotation and efficient magnetic separation (magnetic re-election) as the representative of high-quality iron ore beneficiation technology, the ore beneficiation process should be as efficient and simple as possible.
Therefore, researches on ore separating technology and ore flotation equipment should be strengthened to find out the most suitable process to achieve the best results.
Anti-flotation process has important applications to improve metal recoveries, so experts should actively promote the study of anti-flotation reagent.
The height of flotation machine was high brought many issues, including inconvenient operation and maintenance, consumed too much energy to feed the mineral, needed more pressure of bubble generation in the bottom and replace the bubble generator inconvenient.
The height of this machine was far lower than flotation separator in the past, so the problems can be avoided completely.
The theoretical studies showed that, the bubble size inversely to the height of flotation machine, but the recovery proportional to the height, conventional ore flotation equipment cannot solve this contradiction.
This machine reduced the actual height and increased the separate room, so the machine reduced the bubble size and enhanced the recovery.
The effect of previous flotation separator was not good to deal with the coarse and fine particles, because of coarse off easy but fine not easy shedding.
The structure of this machine enhanced the risk of collision of coarse with the bubble, and the fine particles increased selectivity because of being washed many times.
At the same time of Continuing to attach importance to the iron ore concentrate to raise iron content and reduce silicon technology, attention should also be paid to reduce other harmful impurities such as S, P, K, Na, F and so on.
The ore beneficiation technology of dissemination size fine red iron ore and complex multi-metal red iron ore should be further strengthened in order to further improve the utilization of lean red iron ore.
