Study on Efficient Recovery Process of Fine Grained Ilmenite in Panxi Area

According to the problem that the grade and recovery rate of fine grained ilmenite in Panxi area cannot be satisfied simultaneously by high gradient strong magnetic separator,a separation process combined with flotation using the suspension-vibration conical concentrator and high gradient strong magnetic separator as the enrichment equipment for flotation raw material was carried out in laboratory. The results show that the content of-19 μm slime,which interferes the flotation,in the flotation raw materials by the process with suspension-vibration is lower than that of the materials by process with singular magnetic separation. The combined process of suspension-vibration and flotation has an optimum recovery of fine grained ilmenite containing 10.57% TiO₂,which can obtain qualified titanium concentrate containing 47.20% TiO₂,with 13.29% of yield rate and 60% of recovery rate for TiO₂,respectively.
