The Indonesian Opportunity - Gulf Manganese
2022-1-31 · Indonesian “Value Adding” laws introduced in 2009 prevent the export of minerals unless the mineral has been “upgraded” in Indonesia. Whilst there are several small silicomanganese smelters in Indonesia, there is not any significant facility for the production of high grade ferromanganese alloy. As a result, Gulf identified the opportunity to build a
