Manganese ore can generate gray-white brittle metallic element, that is, Manganese, which is alloyed with steel to increase strength, hardness, wear resistance
Gold ores refer to the minerals having gold elements or gold compounds. Through beneficiation, gold ores can be processed into gold concentrates.
Copper is mainly used in manufacturing of electrical equipment, construction such as roofing and plumbing as well as industrial materials such as thermal converter and alloys.
Iron ores are rocks and minerals from which metallic iron can be economically extracted. Iron ore are the raw materials to produce pig iron that is the main source of making steel.
Gabbro is a coarse-grained, dark-colored, intrusive igneous rock. It is usually black or dark green in color and composed mainly of the minerals plagioclase and augite.
Andesite is the name of a family of fine-grained, extrusive igneous rocks that are usually light to dark gray in color.
Marble is a kind of recrystallized limestone which softens under high temperature and pressure re-crystallizing to form marble as the minerals change.
Gravel consists of small rocks that are used as aggregate in concrete or paving. This material is also used to create a structural base for a roadway, or to aid in soil drainage.
Dolomite, with hardness of 3.5-4 and specific gravity of 2.85-2.9, is widely distributed in nature. Dolomite is a carbonate mineral including iron dolomite and manganese dolomite.
Granite is one kind of igneous rocks formed by the condensate of magma below the surface. In building industry, granite can be everywhere from roof to floor.
River stone is a kind of natural stone. It is mainly from the mountain which is raised from ancient riverbed because of the earth’s crust movement million years ago.
Basalt is very common stone with high hardness in aggregates industry. Benefit from its good physical and chemical properties, basalt is widely used in highway, railway and many other constructions.
