1999.10.1 Abstract. Manganese (Mn) ore deposits are widely distributed in China and can be divided into six types based on origin and subsequent modifications: (1) sedimentary, (2) volcanic-sedimentary, (3) metamorphosed, (4) hydrothermally modified, (5) hydrothermal, and (6) supergene. Sedimentary and supergene Mn ore deposits are economically the

2019.7.18 Abstract—Although Russia has considerable reserves of manganese, the quality of its manganese ore is relatively poor. (Its mean Mn content is 9–23%, with a high content of harmful impurities, primarily phosphorus). In terms of economic security, it is essential to create a Russian source of manganese. This entails enrichment of the lean
