Crushing


Ore is hauled to the conveyer belt using an LHD. Thereafter it is transported from underground to the surface for crushing. The first stage of size reduction involves ore being reduced to  about 100% passing 150mm. Crushing is done using a Jaw Crusher.  The ore is conveyed to a stockpile which acts as buffer storage  to ensure continuity. The ore is withdrawn from underneath the  stockpile through vibrating pan feeders. Secondary and tertiary  crushing is carried out as an independent unit. This reduces the  top size from 150mm down to 36mm, while the tertiary crusher  further reduces the material to 96% passing 12mm. The ore then  goes into silos and is fed onto the conveyor by vibrating feeders  underneath
