Manganese Slag - an overview ScienceDirect Topics

Manganese slag is a by-product of ferromanganese alloy manufacturing. Two kinds of slag can be generated in the production of ferromanganese and ferromanganese–silicon alloys: air-cooled slag also known as lumpy slag, and water-cooled slag also known as granulated slag. 90 Approximately 900 kg of manganese slag is generated per tonne of ferromanganese alloy produced, 90 and the global ...
