To mine nickel, the team at Raglan starts from a surface portal using a ramp to get underground to where the ore body is located. It is drilled out of the rock and trucked up to the surface where it is fed into a crusher to break it down to the required size before being fed into a concentrator, where the rock is crushed into even smaller pieces.
