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. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Highwall mining is also safer than other types of mining, and when, it occurs at the surface, it often produces the same amount of output as mining underground does. Smaller blocks of coal can be accessed with high wall mining, and operations can take place around structures or geological impediments that may otherwise impinge upon the production of coal.

Milling follows the mining process, which is intended to extract the uranium from the ore. Milling is largely a chemical process, which yields a product much higher in uranium content than mining, but not yet pure enough for the fabrication of nuclear fuel. Several chemical processes used in milling were summarized.
