Progress on tellurium enrichment in the ocean ferromanganese crusts

The element tellurium is widely used in industrial production, but it is depleted in the earth's crust and riched in oceanic ferromanganese crusts. The authors in this paper reviewed the study about the enrichment process of tellurium in ferromanganese crusts, and it is found that the tellurium content in ferromanganese crusts in various regions is different. For example the tellurium in the E 90° ridge region in Indian Ocean with the increasing trends from north to south. Temporally, the content of tellurium in the old crust is higher, and the tellurium flux would vary with the growh ratios of crusts.The Tellurium element occurs as multi-mineral phases and has multi-sources in ferromanganese crusts, which is controlled by the oceanic physical and chemical process. This research would be beneficial to the development of mineralization theory of dispersed elements.
