Abstract
Systems and methods for the recovery of silver are generally described. Certain embodiments are related to innovations newly developed within the context of the present invention that exploit the ability of elemental silver (i.e., silver metal in an uncharged, unreacted state—and in certain cases, in relatively high purities) to be recovered from liquids (e.g., suspensions and/or solutions) containing non-elemental silver (i.e., silver ions, silver salts, silver complexes, silver compounds, etc.), by exposing the non-elemental silver to certain reducing agents.
Claims22
A method of producing elemental silver from a silver-containing solution and/or suspension that contains solids comprising non-elemental silver, the method comprising:
- combining the silver-containing solution and/or suspension with a reducing agent such that at least a portion of the solids comprising the non-elemental silver are exposed to the reducing agent to convert at least a portion of the non-elemental silver from the solids to elemental silver.
A method of producing elemental silver from a silver-containing solution and/or suspension, comprising:
- combining the silver-containing solution and/or suspension comprising silver in non-elemental form with a reducing agent, such that the reducing agent contacts the silver in non-elemental form, and the silver in non-elemental form is reduced to elemental silver.
