Project milestones


  • Knowledge acquisition, idea process, process evaluation and tests


  • Practical tests with absorption of bottom sediments in the Baltic Sea


  • The separate projects in Bothnian Bay and the Baltic Sea are, by chance, brought together


  • Ocean Minerals AB (SOM AB) is established, and the permission application is started.

  • Initial contacts with potential partners

  • SOM AB presents a proposal to the Swedish government on how to prevent the bottom death in the Baltic Sea

  • The manganese deposits are verified through an expedition


  • LOI with LKAB on development of process technology, infrastructure and receiving of minerals

  • Collaboration with Vattenfall and SSAB in the Baltic Sea project

  • The survey vessel R/V Bothnia Surveyor is acquired

  • The application for a research permit is sent to the Ministry of Industry (November), which forwards the matter to the Geological Survey of Sweden (SGU)


  • SGU recommends the government to approve the research permit (June)

  • Successful test with a unique method that releases iron and manganese without impurities from the manganese nodules

  • The operations is presented to the Swedish Minister of Industry

  • MKB (environmental impact statement) starts

  • Capitalization process initiated


  • Surveys regarding environmental impact start in Bothnia bay

  • Surveys finalized

  • Finalizing of the MKB for Bothnia Bay

  • In parallel, ongoing work with the Baltic Sea-project


  • Application for extraction of nodules is filed to Swedish government

  • Possible decision regarding extraction from the government


On the Bothnia Bay seafloor lies small potato-sized lumps – nodules – that contain minerals. In the Baltic Sea lies sediments.


Via an air-lift technique, developed by Scandinavian Ocean Minerals, the seafloor is gently harvested for nodules or bottom sediment.


On board the ship, nodules are filtered or, if sediment centrifuged


Water and material that is not used is returned directly to the seafloor, which becomes oxygenated in the process.


Nodules and sediment are transported to land where nodules are refined into, among other things, manganese, iron, silicon (used for batteries, solar cells and semiconductors) while sediment becomes biogas, hydrogen gas or green coal (used for fossil-free steel).
