Abstract
Described herein are compositions and methods for preferentially separating mercury from a metal product where both are present in an ore leachate. The separation is accomplished by adding a precipitating agent and a coagulant to an ore leachate followed by separating a mercury-laden precipitate therefrom to collect the treated leachate. The treated leachate includes about 0 to 50% by weight of the mercury and about 90% to 100% by weight of the metal product present in the ore leachate. In embodiments, the method further includes adding a flocculant to the ore leachate prior to the separating of the mercury-laden precipitate.
