Manganese is important basic Industrial minerals of bulk raw materials. Manganese is the most basic elements of steel, have a major impact on steel, all the steel and its alloying contains Manganese. Most Manganese perform compound in nature, almost all kinds of ores and silicate rocks containing manganese mineral. The primary products of Manganese including metallurgical manganese ore, manganese powder, manganese carbonate powder, chemical oxide manganese powder manganese dioxide powder and battery. The metallurgical industry is the largest user of manganese ore, the main function are deoxidizer and desulfurizer of ironmaking and steelmaking. More than 90% of the total production of manganese ore for the production of manganese ferroalloys. China is the huge country which produce manganese ferroalloys and manganese, the manganese ferroalloy. The production are more than 4.45 million tons .After the break of the process of Manganese production of stainless instead of nickel. The surge in demand for EMM EMM production of 600,000 tons. Annual metallurgical manganese ore are more than 10 million tons. Annual metallurgical manganese ore in more than 10 million tons. The amount of the total about 2%; 5% of manganese resources for other industries, such as light industry (matches, the Indian paint, soap), building materials industry (glass, ceramic and enamel coloring agent and bleaching agent), the electronics industry (magnetic material) Environmental Protection (adsorbent), agriculture (compound fertilizer, compound feed) and defense industry.  

According to the statistics of metal powder supplier, at the end of 2008, the world's terrestrial manganese ore reserves, reserve base of a total of 5.7 billion tons, which 500 million tons of reserves, reserves the basis of 52 million tons. About 9-10 million tons of manganese ore reserves of the global for the development and commercial value of more than 95% distribution in South Africa, Gabon, Australia, Brazil, Ukraine, China and India and other countries, most of them for the oxidation of manganese ore. Global manganese metal distribution was uneven, South Africa and Ukraine, two countries has the maximum amount of manganese resources, about 71.8 percent of world manganese resources of manganese ore resource in South Africa, Ukraine accounted for 11.9%, of which the world's basic reserves the top four countries accounted for 92.88% of the world's total reserve base. The gap between the world's manganese ore quality is obvious, the world's high grade manganese ore (more than 35% of manganese) resources are mainly distributed in South Africa, Australia, Gabon and Brazil.  

In addition, the world ocean floor contains extremely rich mineral resources, manganese nodules is one of them, which is an important potential resource of manganese. Manganese nodules is settling in the ocean floor of iron, manganese oxide of aggregate (ore). It contains more than 30 kinds of metal elements, including manganese, copper, cobalt, nickel and so on to have valence metal has great commercial economy value. Manganese nodules are widely distributed in the world ocean 2000-6000 m depth the bottom of the sea surface, and to create in 4000-6000 m depth beneath the best quality. Deep sea seabed manganese nodules about 4400 tons/km2, total reserves estimated at more than 3 trillion tons, including manganese, copper, cobalt, nickel four metal reserves than its corresponding reserves on land to one to three order of magnitude. The Pacific Ocean, the Indian Ocean and the Atlantic ocean have rich seabed manganese nodules resources, but the most development foreground area is the Pacific Ocean southeast of the Hawaiian islands sea area. 

As the world's terrestrial manganese ore reserves are dwindling, there is a growing emphasis on the use of undersea manganese nodules. Western countries, especially in countries without land manganese deposit, extensive research and development, such as the United Kingdom, Japan, Germany, France, Sweden and Canada and other seabed manganese nodules. 1980s, the miners of the United States, Soviet Union, Japan, Germany and other countries of multinationals, chain bucket, hydraulic lifting and air lifting method for mining manganese nodules, Nissan 300-500 tons of manganese nodules. Smelting technology, the United States, France, Germany and other countries and built a pilot plant processing of manganese nodules for more than 80 tons. Seabed manganese nodule mining, smelting technology has been basically mature, once commercially viable, can form a new industry, to enter the batch-scale production.
