Mining the mineral microbiome: Current Biology

Microbes interacted with minerals for billions of years before multicellular organisms started to evolve. A better understanding of the mineral microbiome and its mechanisms of mineralisation and solubilisation could help with the exploration, production and ultimate recycling of mineral resources.

Mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure.

In deep-sea mining, a collector vehicle is sent to pick up these nodules from the deep seabed. The vehicle creates a sediment cloud known as a ‘collector plume,’ seen here in the foreground, that is then carried away by ocean currents.
