Abstract
A process for economically recovering metal values, especially precious metal values, from waste waters comprising a mixture of natural surface water, industrial waste water and organic waste, where the metal values appear in concentrations below levels previously commercially of interest, including the steps of concentrating the metal values of the waste waters by bacterial treatment thereof to imbibe and capture the metal values from the waters and immobilize them in a sludge, coagulating and separating the sludge from the water, de-watering the sludge and burning off the organic matter, and recovering selected metal values by inorganic metal-winning process steps.
