Ore processing Waihi Gold

Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself.

Financial modelling of stockpiles in a mining project

Modelling stockpiles is a crucial component of a financial model in a mining project, because most likely mining companies are not able to mill all the ore that they mine. Further, this stockpile of contained metal has a monetary value which needs to be reflected on the balance sheet.
