Flotation apparatus comprising an elongated tank having at one end both a submerged feed inlet and an upper froth overflow, a clarified effluent overflow at the opposite end, and a bottom outlet for removing settled solids. A mixing valve assembly is associated as a feed inlet for admixing an aeration stream with the primary feed as it enters the tank; and a trap is provided adjacent the feed inlet for removing relatively large air bubbles from the feed before it enters the main flotation zone. |
