Comminution | Multotec

The process of comminution is the crushing and grinding of a material / ore to reduce it to smaller or finer particles. The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials. The process is most often used in the field of mining and / or mineral processing, where mineral ore is broken down into small particles, by hammer ...

Ores and Minerals Introduction, Extraction, Concentration ... VEDANTU

The ore is generally associated with Earthy impurities like Sand, rocks, and limestone Known as Gangue or Matrix. A substance added to ore to remove the impurities is called flux. The combination of gangue with flux in ores forms a fusible material called Slag. The concentration of ore is the process of eliminating gangue from the ore.

Innovations: Introduction to Copper: Mining Extraction

Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is ...

Copper extraction Wikipedia

The average grade of copper ores in the 21st century is below % copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.

9 Ore Deposits and Economic Minerals Mineralogy OpenGeology

Although tin melts at a relatively low temperature (232 °C), copper melts at 1,983 °C, a temperature too great to be easily achieved at the time. However, clever metal workers discovered that a mix of one part tin and three parts copper melts at 1,675 °C, which was low enough to make bronze manufacturing possible in many places.
