About manganese oxides

HS code 2820 covers manganese oxides, which are a group of chemical compounds composed of manganese and oxygen. These compounds play a crucial role in various industries, including steel production, battery manufacturing, and the production of glass, ceramics, and pigments. Manganese oxides are an essential component in the global economy, contributing to the development of a wide range of products and technologies.

Production process

Manganese oxides are typically produced through the oxidation of manganese ores or the thermal decomposition of manganese salts. The most common production method involves roasting manganese ores in the presence of air, which causes the manganese to react with oxygen and form various manganese oxide compounds. The specific type of manganese oxide produced depends on factors such as the composition of the ore, the temperature, and the duration of the roasting process.

Production inputs

The primary inputs for the production of manganese oxides are manganese ores, which are mined from natural deposits around the world. These ores are typically composed of a mixture of manganese minerals, such as pyrolusite, braunite, and bixbyite. In addition to the raw materials, the production of manganese oxides requires specialized equipment, such as furnaces, kilns, and reactors, as well as energy sources, such as electricity or natural gas.

Production outputs

The main outputs of the manganese oxide industry are various forms of manganese oxides, including 2820 Manganese oxides, 2820.10 Manganese dioxide, and 2820.90 Other manganese oxides. These compounds are used in a wide range of applications, such as the production of 7202.11 Ferro-manganese, 8506.10 Manganese dioxide primary cells and primary batteries, and 3207.40 Vitrifiable enamels and glazes. The outputs of the manganese oxide industry are essential inputs for many other industries, contributing to the overall development and growth of the global economy.
