Electrolytic manganese metal industry experience based China
Electrolytic manganese residue (EMR) is a general industrial solid waste containing manganese (Mn) and heavy metals that is produced in the process of Manganese is an essential element for modern industrial societies. Its principal use is in steelmaking, where it serves as a purifying agent in iron-ore refining and as an alloy that converts iron into steel. Although the amount of manganese consumed to make a ton of steel is small, ranging from 6 to 9 kilograms, it is an irreplaceable Manganese U.S. Geological Survey USGS.gov

Southern China's manganese resource assessment: An
Manganese is, an important industrial mineral used in the manufacture of various products, including in the refinement of iron ore and as an alloy in steel. China has rich resources of manganese (Mn), with the majority of deposits located in southern China. The common types of Mn deposits are sedimentary, hydrothermally modified, and Mining began in earnest in Xiushan county 30 years ago during China’s initial economic reforms under Deng Xiaoping. As a remote, mountainous corner of the Chongqing region in Sichuan province, the only way for Xiushan to develop was to exploit its mineral resources, of which manganese was the most valuable.Mining and conflict in Chongqing China Dialogue
