Abrégé

Provided herein are processes and methods for the bio-extraction of trace metals from a metal-oxide containing starting material (e.g., a metallic ore). The processes and methods may utilize metal-oxide reducing bacteria to electrochemically reduce metal oxides in the ores, thereby freeing valuable trace metals. In preferred embodiments, the processes and methods may utilize metal-oxide reducing bacteria from the group Shewanellaceae and/or the group Geobacteraceae.

Classes IPC  ?

• C22B 3/18 - Extraction de composés métalliques par voie humide à partir de minerais ou de concentrés à l'aide de micro-organismes ou d'enzymes, p. ex. de bactéries ou d'algues
• C12P 3/00 - Préparation d'éléments ou de composés inorganiques à l'exception du dioxyde de carbone
• C21B 13/00 - Fabrication de fer spongieux ou d'acier liquide par des procédés directs
• C22B 1/24 - AgglutinationBriquetage
• C22B 47/00 - Obtention du manganèse

Abrégé

A buoyancy system for an underwater autonomous vehicle is provided. The buoyancy system includes one or more pressure vessels, a primary pump connected to each of the one or more pressure vessels with the primary pump configured to pump liquid from the one or more pressure vessels. The buoyancy system further includes a controller communicatively coupled to the primary pump and configured to operate the main pump via wireless or wired communication, and a power source configured to provide power to the controller and the primary pump.

Classes IPC  ?

• B63B 21/50 - Dispositifs d'ancrage pour navires spéciaux, p. ex. pour plates-formes flottantes de forage ou dragues
• B63B 22/20 - Moyens de ballastage
• B63G 8/24 - Réglage automatique de la profondeurDispositifs de sécurité pour augmenter la flottabilité, p. ex. ballast amovible, corps flottants
