Ore Hoisting Methods
The main or upper gate is of the vertical sliding undercut plate type and is actuated by a large air cylinder. The ore is drawn through this gate into a measuring hopper equipped with an undercut arc gate actuated by another air cylinder. Below this gate is a short, steep slide or chute that directs the ore into a 112-cubic-foot skip.
