Stockpile Algorithms

Use stockpile balance algorithms to control how Reconcilor calculates depletion grades when material is reclaimed from a stockpile. An algorithm applies when reclaim events occur for the selected stockpile.

Reconcilor has 5 algorithm types:

1. Average – The default algorithm if no others are defined. Grade weighted averages are used for removals.
2. FIFO – First In, First Out. The first load delivered to the stockpile is the first load reclaimed. Reconcilor tracks parcels of material delivered and reclaims them in order.
3. LIFO – Last In, First Out. The last load delivered to the stockpile is the first load reclaimed. Reconcilor tracks parcels of material delivered and reclaims them in reverse order.
4. LIFO-Average – Applies grades from LIFO modelling back to the beginning of the previous shift before reverting to average weighted grades.
5. LIFO-Configured – Uses LIFO for a configured period (days) before reverting to Average. The look back period to use when setting the LIFO-Configured option should be defined by the expected frequency of additions to that stockpile. For example, if a stockpile routinely has no additions for two days, then the algorithm should have a configured look back period of greater than 2 days. This avoids incorrect calculation of the depletion grade.
