The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. ... Dump trucks haul the rock to the primary crushers in the open pit or to the ore stockpiles from underground.
Gravity reclaim stockpiles are an effective way to store large quantities of material. Our gravity stockpile reclaim designs are engineered based on the measured flow properties of the bulk solid being handled, using proven in-house developed methods.. Each of our gravity stockpile reclaim designs is based on an expanded flow principle which incorporates mass flow hopper(s) at the stockpile base.
