The Basics of Manganese Mining and Processing. While exposure to manganese fumes, dust and compounds should be avoided, in safe formulas manganese is used by most everyone. The fact that manganese is such an important metal in our lives makes it clear that that mining of it is equally important. What is Manganese Used For?
High manganese steel. Steel with a manganese content of 11% to 18% is called high manganese steel. The chemical composition of commonly used cast high manganese steel ZMn13 is: Mn content is 11% to 14%, C content is 1% to 1.4%, Si content is 0.3% to 1%, P content is less than 0.03%, and S content is less than 0.05% .
