Rocks with large concentrations of minerals, are called ores. Mining depends on finding good quality ore, preferably within a small area. The next step is to get the rocks which contain the mineral out of the ground. Once the ore is on the surface, the process of getting the mineral you want out of the rock can start.
underground mines; the crushing and grinding of ore; the separation of valuable minerals from matrix rock through various concentration steps; and at some operations, the drying, calcining, or pelletizing of concentrates to ease further handling and refining. Figure 11.24-1 is a general flow diagram for metallic mineral processing.
Crushing & grinding: For most of the mineral ores, due to the geological evolution, they are contained in or stick to rock veins. After mining the mineral ore is mined from underground, then the first procedure is to crush the big lump rock to small …

crushing, grinding, and milling or fine grinding. In mineral processing parlance, comminution in coarse range is known as "crushing" and in fine range it is called "grinding". Comminution : The act or process of reduction of particle size with attendant increase in surface area and population of particles, usually but
