Insights into the global flow pattern of manganese

The original supply in the manganese flow is composed of manganese from ore and scrap. Ore included manganese and iron ore, from which iron is principally recovered, but its manganese content is also used (Nakajima et al., 2008).In the refining stage, ores and scrap are transformed into various intermediates by smelting, …
