The ALS Iron Ore Technical Centre has been designed and built to accommodate scalable fused bead XRF processing capacity in excess of 10,000 samples per day With specialist expertise in processing hematite, magnetite and all forms of iron ore, the centre provides extensive ore characterisation.
For instance, a logic was implemented that allows trucks to be re-routed to a stockpile with a grade and hardness range fitting the loaded ore, if the tip pocket is utilized fully In addition, two methods for the grade blending were implemented Blending on the coarse ore stockpile happens according to ,
Simulation to reduce variability in iron ore stockpiles ,
The market requires successive shipments of iron ore to be uniform in composition, for several elements (particularly iron, silicon, aluminium and calcium) Variations in mine production cause individual train loads arriving at the shipping yard to vary in composition Appropriate stacking of incoming ore helps smooth the variability
