Title (EN) DISPOSAL OF ACCUMULATED WASTE SOLIDS FROM PROCESSING OF TITANIUM-BEARING ORES
(FR) ELIMINATION DE DECHETS SOLIDES ACCUMULES PENDANT LE TRAITEMENT DE MINERAI DE TITANE
Abstract: front page image
(EN)A process for treating neutralized waste solids from the processing titanium-bearing ores, whereby the neutralized waste solids are contacted with an acid under conditions effective to dissolve at least some of the waste solids, and then residual undissolved solids are separated out prior to injection of the remainder into a subterranean waste disposal well. The process is particularly adapted to disposal of hazardous metal waste solids which have been deposited over time in a waste disposal pond but which are judged as posing a hazard for migration from the pond to surface and subterranean waters.
(FR)L'invention porte sur un procédé de traitement de déchets solides neutralisés accumulés pendant le traitement de minerai de titane consistant: à les mettre en contact avec un acide dans des conditions en assurant au moins la dissolution partielle; à en séparer les solides résiduels non dissous; et à injecter les solides résiduels non dissous dans un puits souterrain d'injection. Le procédé est particulièrement adapté à l'élimination des déchets solides de métaux dangereux ayant séjourné dans des bassins ad hoc, mais présentant un risque de migration vers les eaux de surface et souterraines.
