Mineral ore is formed by various materials with millions of years of evolution. Mineral ors can be divided into lean ore, common ore and rich ore. As for the ores mined from the quarrying process, as they are mixed with some barren rocks, their grade declines, which is called ore dilution. Ore dilution will increase the transportation cost and screening cost of the ores. In addition, minerals can also be divided into metal ore and non-metallic ore. Before the mineral ores can be used, they must be beneficiated and smelted to remove the foreign matters.
The main types of mineral ores include non-ferrous metal ores such as iron ore, copper core, manganese ore and zinc ore and non-metallic ores such as coal, basalt, limestone and granite.
A quarry can be on-ground or underground. Traditional quarry relies on manual labor, so that the quarrying speed is low, and it wastes a lot of labor and materials. In addition, traditional quarrying has high production cost and long time. With the constant development of modern quarry machine and quarry equipment, automatic quarrying has become the standard configuration of emerging quarry. Automatic quarry machine and limestone machinery used for limestone mining can greatly reduce the labor cost and ensure the safety of the workers.

Mining machine develops together with modern quarry and it is the mechanical machine used in the mineral ore exploration. The main mining machines include coal mining crusher and coal crushing machine. The basalt mining mainly uses crushing equipment, mining sieve, classification equipment and excavation equipment. In addition, according to the specific needs of the customers, sometimes transportation vehicles and short-distance conveyor equipment are also needed.
