Deep sea mineral - manganese nodule
Release time：
2015-11-02 00:00
The ocean floor is rich in mineral resources, and manganese nodules are one of them. It contains more than 30 kinds of metal elements, among which manganese, copper, cobalt and nickel are the most valuable for commercial development.
Manganese nodules are widely distributed in the surface layer of the sea floor at the depth of 2000-6000 meters in the world ocean, and the quality generated at the depth of 4O00-6000 meters is the best. The total reserves of manganese nodules are estimated to be more than 300 billion tons. Among them, the North Pacific has the largest distribution area, accounting for more than half of the reserves, about 1700 billion tons. In places where manganese nodules are concentrated, there are more than 100 kilograms per square meter, literally covering the sea floor one by one.
Manganese nodule is also called polymetallic nodule, manganese ore ball, manganese ore cluster, manganese nodule, etc. It is an aggregate of iron and manganese oxides, and its color is often black and brown black. The forms of manganese binding are various, including spherical, elliptical, potato, grape, flat, slag, etc. The size of manganese nodules also varies greatly, ranging from a few microns to tens of centimeters, and the largest is tens of kilograms.
Manganese nodules not only have huge reserves, but also. It will continue to grow. The growth rate varies from time to place, with an average length of 1mm per thousand years. Based on this calculation, the global manganese nodules increase by 10 million tons every year. Manganese nodules can be called "inexhaustible" renewable polymetallic mineral resources.

Molybdenum resource reserve distribution and output
The average content of molybdenum in the crust is about 0.00011%. There are about 20 kinds of molybdenum ores found, among which molybdenite is the most valuable one, followed by tungsten phase calcium ore, iron platinum ore, color molybdenum lead ore, platinum copper ore, etc. According to the data released by the US Geological Survey in 2015, the global molybdenum resource reserves are about 11 million tons, and the proven reserves are about 19.4 million tons
Overview of Graphite Ore Flotation
Graphite mainly refers to natural graphite, which is a non-metallic mineral formed under specific high-temperature reduction conditions of carbon element, and is most commonly found in marble, schist and gneiss
