Abstract
The present invention relates to methods and organisms for concentrating and recovering metals and minerals from aqueous media. In the inventive method, a eucaryotic aquatic organism capable of concentrating a metal or mineral is contacted an aqueous medium containing the metal or mineral, in order to concentrate the metal or mineral in the organism. Following concentration, the metal or mineral accumulated by the organism may be recovered. Sponges are very preferable organisms for isolating metals, e.g, gold and silver, from seawater.
Claims2
A method of recovering metals and minerals from sea water, comprising:
- contacting a sponge that harbors bacteria capable of concentrating said metal or mineral with sea water, said sponge having a symbiotic relationship with said bacteria, so as to concentrate the metal or mineral in the bacteria;
- and
- recovering the concentrated metal or mineral from the bacteria.
A method of recovering metals and minerals from sea water, comprising:
- contacting a sponge that harbors bacteria capable of concentrating said metal or mineral, said sponge having a symbiotic relationship with said bacteria, said bacteria being Cyanobacteria;
- and
- recovering concentrated metal or mineral from said sponge.
