A typical minetomill optimization effort includes four steps: (i) scoping study, (ii) analysis, (iii) optimization, and (iv) implementation. The scoping study consists of a site visit to review current mining and processing practices and discover possible areas for improvement. The analysis step involves a detailed survey of all aspects of a

At Boddington the process residence time is about two days, so in a month two days of mill reporting is based on material from the previous month and two days of crusher feed at the end isn't reported fully in the mill figures. This means that for a 30 day month 13% of the material is unmatched in the reconciliation.

Underpinning the mining process is a continuum of prediction, specifically of tonnes, grade and recovery from exploration to grade control, through shortterm mine design, to mining and processing. The interdependence of one activity on the other is so strong that it can be difficult to partition the activities and determine where there are issues, if any. Reconciliation is the process that ...
