Study of Key Flotation Technologies for Yuanjiacun Micro-fine Mixed Iron Ores |
| |
| Abstract: | Considering that Yuanjiacun iron ores for flotation are fine in feed size and diverse in kinds of iron ores, big circulation anionic reverse flotation technology is innovatively developed and successfully applied in Yuanjiacun Concentrate Plant. Iron concentrates with the grade of 66. 25% and recovery of 85. 20% are obtained by using this process in expanded & continuous tests and concentrates with the grade of 65. 92% and recovery of 88. 55% are obtained using this process in the industrial production. |
