Copper among others, like steel is one of the key strategic materials for production in many industries. That material is known for centuries, mainly because copper is a main component of bronzes hence the name: the Bronze Age. The Latin name of copper (Cuprum) shows its roots it can be translated as "the material from Cyprus", where in antiquity ages was mainly mined.

The underflow is sent to a secondary ball mill and trommel screen, for additional grinding and classification. Using froth flotation, the copper minerals separate from the gangue and rise to the froth layer of the flotation cell. In turn, the copperrich bubbles are removed or transferred to the next stage of flotation for further processing.

Defect. A common defect caused by CNC milling errors is burns on the surface of the workpiece. Burns can occur when the workpiece is overheated. The defect on the workpiece may be at the corner or edge of the material. It manifests as cutter marks on the surface, rough edges or raised marks. In addition, the tool wears out faster than normal.
