AI Technical Summary
In the prior art, it is difficult to directly reuse the blast furnace bag ash and sintering machine head ash, the comprehensive utilization value is low, and secondary pollution is easily generated during the disposal process.
The water washing pretreatment system and the valuable element recovery system are used to separate and recover the valuable elements in the blast furnace bag ash and the sintering machine head ash through combined water washing, magnetic separation, flotation and other processes.
The grading utilization of valuable elements in blast furnace bag ash and sintering machine head ash is realized, the recovery rate and product value of valuable elements are improved, the process cost is reduced, and secondary pollution is avoided.
