APPARATUS AND METHODS FOR MERCURY AND PRECIOUS METAL RECOVERY

摘要

Apparatus and methods for mercury and precious metal recovery are provided. The apparatus includes a granulometric separator for separating a feed by particle size; a centrifugal concentrator in flow communication with the granulometric separator for isolating and concentrating an elemental mercury-containing fraction of the feed; and an accumulator tank for collecting elemental mercury from the elemental mercury-containing fraction. The accumulator tank has an inlet in flow communication with the centrifugal concentrator; an outlet; a plurality of baffles defining a serpentine flow path to slow the flow of the elemental mercury-containing fraction from the inlet to the outlet; and a mercury accumulation area for collecting elemental mercury settling from the elemental mercury-containing fraction.
