A separation installation includes the above settler and a method for separating a clarified liquid from a thickened slurry of a mineral slurry.

Abstract: A process for producing alumina trihydrate includes a digestion step, a separation step, and a precipitation step the separation step including: b1) pretreating a slurry from the digestion step by adding a flocculant to said slurry and mixing the flocculant and the slurry, b2) settling the resulting flocculated slurry in a gravity settler vessel, b3) determining a measured value representative of the concentration of solid particles in the resulting clarified liquor, b4) comparing the measured value with a predetermined threshold, b5) feeding said clarified liquor directly to the precipitation step, while the measured value is less than said predetermined threshold, and b6) redirecting said clarified liquor to the pre-treatment step b1), when the measured value is more than said predetermined threshold. An installation may be configured for operating said process.

Abstract: An educational money management game comprises a host platform provider, a remote interface device in communication with the host platform provider and a moneybox in communication with the interface device. The interface device displays interactive game scenes produced by the host platform provider to a user. The moneybox includes a reader for reading the monetary value of coins inserted therein. When the user inserts coins in the moneybox, the monetary value thereof is communicated to the host platform provider and displayed by the interface device to be viewed by the user. The game includes an interactive interface for providing for the user to allot at least a portion of the displayed monetary value to one or more of said allocation options. A network is provided for a plurality of users via the internt using remote interfaces at each user's location. The game scenes produced include a common image displayed by each remote interface.
