MANGANESE Manganese (Mn) is essential to iron and steel production by virtue of its sulfur-fixing, deoxidizing, and alloying properties. Steelmaking, including its ironmaking component, accounts for most domestic manganese demand, presently in the range of 85% to 90% of the total. Manganese ferroalloys, consisting of various grades of ferromanganese and silicomanganese, are used to …
Gold ore Refers to the gold-bearing ore mined from the mine by hand or machinery, which also contains other metal impurities. Gold is a crystal at normal temperature, equiaxed crystal system, vertical lattice, natural and good crystal form is extremely rare, often in the form of irregular granules, agglomerates, flakes, reticular, dendritic, fibrous and …
BASALT Basalt is an aphanitic igneous rock with less than 20% quartz and less than 10% feldspathoid by volume, and where at least 65% of the feldspar is in the form of plagioclase. Basalt features a glassy matrix interspersed with minerals. Basalt is defined by its mineral content and texture, and physical descriptions without …
LIMESTONE Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Most limestone is composed of skeletal fragments of marine organisms such as coral or foraminifera. Limestone makes up about 10% of the total volume of all sedimentary rocks. The solubility of …

COBBLE Cobblestone is a kind of natural stone from the sandstone mountain which was formed by the river bed after the crustal movement happened in the tens of millions of years ago. They are squeezed and rubbed during the process of torrential flooding and water transportation. After many years, their irregular edges are rubbed …
