Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains. The value of the metals or minerals
Some mines have the primary crusher located in the mine, using conveyors to transport the crushed ore to the secondary and tertiary crushers or directly to the mills. The crushing stages will reduce the iron ore from several feet in diameter at the primary stage to six inches down to one half or three eighths of an inch as a final product.

If the dip is greater than about 50°, then systems using gravity to move the ore can be considered. If the dip is less than about 25°, then systems using rubber tired equipment for ore transport can be considered. For ore bodies having dips in between these, special designs are required.
Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.
