Large throughput iron ore oscillatory dewatering system
Project Number: P1150A
Amira Program Manager: Olga Verezub
This project is an extension to its predecessor – AMIRA P1150 “Moisture measurement and control for iron ore conveyor systems” – which discovered the optimum oscillation motions to enhance moisture migration for a range of iron ore types; over 1% moisture reduction was achieved for deslimed ROM iron ore product exhibiting bottom moisture migration behaviours; and nearly 2% moisture reduction was achieved for non-deslimed ROM iron ore product exhibiting top moisture migration characteristics.
The key project objectives for P1150A are:
- Characterisation of the mode and rate of moisture migration for each sponsor ore sample (for iron ores not previously tested in the P1150 project);
- Conceptual design, construction and testing of the pilot-scale dewatering system based on sponsor ore sample’s moisture migration mode and rate;
- Feasibility study and conceptual design of the full-scale large throughput dewatering system including onsite implementation strategy of the full scale advanced oscillatory dewatering system.
Benefits from sponsoring this project:
Once implemented in operation, a dewatering system based on this technology can provide direct multi-million dollars saving for iron ore producers in transport cost; it will also lead to significant indirect benefits in material handling efficiency gains for increasing throughput operation.
