    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.

    Abstract: Embodiments of the invention relate generally to systems used to measure mercury in gaseous emissions. In one aspect, the invention is directed to the use of an inert covalently bonded material selected from silicon carbide (SiC), silicon oxides (SiOn, n=1-2), silicon nitride (e.g. Si3N4), silicon boride (e.g. SiB6), boron nitride (e.g. BN) and mixtures thereof as material for a thermal pyrolysis unit. In another aspect, the invention is directed to an improved pyrolyzer design, in which a thermal pyrolysis unit comprises a tailpiece that allows water to be injected at the heated exit of the thermal pyrolysis unit. In another aspect, the invention is directed to the use of a coalescing filter in a scrubbing unit. In another aspect, the invention is directed to the use of a hydrophobic filter element in a scrubbing unit. One or more of these elements may be used in a conditioning module of a continuous emissions monitoring system, for example.
