Quantify unrecovered gold rather than relying on gross product weight. Enter theoretical fine gold and the actual fine gold recovered to see the percentage loss and its monetary impact.
Refining reduces total material mass because unwanted metals and other material are removed. Gross weight loss can therefore be enormous without representing gold loss. This calculator isolates the fine-gold component.
If recovered fine gold exceeds theoretical fine gold, the mathematical result becomes a negative loss. In practice this should prompt a reconciliation review of assay, sample representativeness, weights and accounting period.
The percentage of theoretical contained fine gold that was not recovered.
No.
The arithmetic can, but such a result should be investigated.
