Role of pre-crusher stockpiling for grade control in iron ore mining
Whereas this design suits the mining process and is operationally simple, there can be little confidence in the grade of the ore that is fed to the crusher. This makes short-term grade control difficult and reconciliation back to the mine face imprecise. Well-designed and operated pre-crusher stockpiles can overcome these deficiencies.
