AMINE-ALDEHYDE RESINS AND USES THEREOF IN SEPARATION PROCESSES

Amine-aldehyde 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 resins are especially useful as froth flotation depressants, for example in the beneficiation of value materials (e.g., bitumen, coal, o...

Zusammenfassung:	Amine-aldehyde 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 resins are especially useful as froth flotation depressants, for example in the beneficiation of value materials (e.g., bitumen, coal, or kaolin clay) to remove impurities such as sand. The 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. On décrit des résines amine-aldéhyde pour lélimination dune grande variété despèces solides et/ou ioniques des liquides dans lesquels elles sont en suspension et/ou dissoutes. Ces résines sont particulièrement utiles en tant que déprimants de flottation par écumage, par exemple pour la valorisation de matériaux de valeur (par exemple, bitume, charbon ou argile kaolin) afin déliminer des impuretés comme le sable. Les résines sont également utiles pour traiter des suspensions liquides aqueuses afin déliminer les particules solides, mais également pour éliminer les ions métalliques lors de la purification de leau.
