Gold extraction - QueensMineDesignWiki

The primary reason for the significant comminution circuits is because in gold mining the grades are notably low and thus excessive waste material is present, resulting in high mill feed rates. If the ore rock is highly fractured and/or brittle, it is likely that an AG mill be the most economical option in lieu of a SAG mill.
