Title (EN) REACTOR SYSTEM FOR SEPARATION AND ENRICHMENT OF MINERALS FROM A SLURRY CONTAINING MINERALS AND OTHER MATERIALS
(FR) SYSTÈME DE RÉACTEUR POUR LA SÉPARATION ET L'ENRICHISSEMENT DE MINÉRAUX À PARTIR D'UNE BOUE CONTENANT DES MINÉRAUX ET D'AUTRES MATÉRIAUX
Abstract:
(EN) A reactor system has a number of stations arranged to recover mineral particles in a slurry. The system includes a hopper to receive the slurry and barren media having hydrophobic coating to attract the mineral particles. The hopper provides a mixture of barren media and slurry to a tumbler arranged to stir the mixture in order to increase the contact between the slurry and the barren media so as to allow the mineral particles to attach to the barren media to form mineral laden media. The mineral laden media are conveyed to a rinsing station where water jets are used to wash the gangue materials off the mineral laden media. The rinsed mineral laden media are mixed with a surfactant so that the mineral particles are released from the mineral laden media. High-pressure water and air jets are then used to remove remaining surfactant from the released media.
(FR) L'invention porte sur un système de réacteur qui comprend un certain nombre de stations agencées pour récupérer des particules minérales dans une boue. Le système comprend une trémie pour recevoir la boue et des substrats stériles ayant un revêtement hydrophobe destiné à attirer les particules minérales. La trémie fournit un mélange de substrats stériles et de boue à un tambour agencé pour agiter le mélange afin d'augmenter le contact entre la boue et les substrats stériles de façon à permettre aux particules minérales de se fixer aux substrats stériles pour former des substrats chargés de minéraux. Les substrats chargés de minéraux sont transportés vers une station de rinçage où des jets d'eau sont utilisés pour éliminer par lavage les matériaux de gangue des substrats chargés de minéraux. Les substrats chargés de minéraux rincés sont mélangés avec un tensioactif de telle sorte que les particules minérales se trouvent libérées des substrats chargés de minéraux. Des jets d'eau et d'air à haute pression sont ensuite utilisés pour éliminer le tensioactif restant des substrats libérés.
