MODIFIED AMINE-ALDEHYDE RESINS AND USES THEREOF IN SEPARATION PROCESSES

Modified resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These modified resins are especially useful as froth flotation depressants in the beneficiation of many types of materials (e.g., mineral and metal...

Zusammenfassung:	Modified resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These modified resins are especially useful as froth flotation depressants in the beneficiation of many types of materials (e.g., mineral and metal ores), including the beneficiation of impure coal comprising clay impurities, as well as in the separation of valuable bitumen from solid contaminants such as sand. The modified resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water. The modified resins comprise a base resin that is modified with a coupling agent, which is highly selective for binding to solid contaminants and especially siliceous materials such as sand or clay. L'invention concerne des résines amine-aldéhyde modifiées qui permettent d'éliminer un grand nombre d'espèces solides et/ou ioniques en suspension et/ou dissoutes dans des liquides. Ces résines modifiées sont particulièrement utilisées comme dépresseurs de flottation par mousse dans la valorisation de divers types de matériaux (tels que les minerais et les minerais métalliques), y compris la valorisation de charbon impur contenant des impuretés argileuses, ainsi que dans la séparation d'asphalte précieux de contaminants solides tels que le sable. Ces résines modifiées sont également utilisées pour traiter les suspensions liquides aqueuses et les débarrasser des particules solides, ainsi que pour éliminer des ions métalliques lors de la purification de l'eau. Par ailleurs, les résines modifiées contiennent une base résineuse, modifiée par un agent de couplage, qui se lie avec une sélectivité élevée aux contaminants solides et particulièrement aux matériaux siliceux tels que le sable ou l'argile.
