The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.

The occurrence of uranium in different types of rocks is given in Table 2.1. Uranium does not occur in native elemental form. It is chemically reactive and has great affinity for oxygen. Uranium exists in multiple oxidation states, say, +3, +4, +5, and +6, but the +4 and +6 states are predominant among them [ 3 ].

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.
