Abstract:
The varieties and mechanisms of ilmenite flotation agents, the characteristics of the separation equipment and the technological process of fine ilmenite recovery of fine ilmenite were reviewed. Based on practical cases of production, the mechanisms of the regulators and collectors, ideas and innovation of new equipment developments, as well as application of process flow were fully analyzed. In recent years, the use of the flotation regent synergies to develop combination reagents and the development of new separation equipment with compound force field have been a research hot point in recovery of fine ilmenite resources. Moreover, the magnetic separation and flotation combined technological process is the widely used method for such fine ilmenite resources in most concentration plants. In industry, there is still no effective processing method for the recovery of -0.019 mm fine ilmenite, which has been become a challenge needed to overcome.
