The more water that is added, the faster the ore will go through the mill. This means the time it has to be ground will be reduced and a poor grind will result. At the other extreme, if not enough water is used, the ore will not be able to flow through the mill. The result is the ore will not be able to move into the rod load. Because there isn ...
