Gold extraction

Of the numerous major gold mining operations around the world, most utilize a primary crushing circuit which flows into a SAG mill circuit and then a ball mill circuit. 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.


Taking into account all of the issues encountered to date, it is important to be realistic about the chances of success and we have concluded that full recovery, while not impossible, is unlikely. However, we remain confident that a partial recovery will be made, which should allow in due course for the return of at least 50% of Rhombus Gold purchaser funds.
