Abstract
Se describen procesos para consolidar relaves tal como de procesos de mineral basado en metal y no de metal. Los procesos incluyen el mezclado de relaves con una alta concentración de una sal altamente soluble en agua o una solución acuosa de la misma para desestabilizar y consolidar los sólidos en los relaves y separar los sólidos consolidados del agua de proceso.Processes for consolidating tailings such as metal-based and non-metal ore processes are described. Processes include mixing tailings with a high concentration of a highly water soluble salt or aqueous solution thereof to destabilize and consolidate the solids in the tailings and separate the consolidated solids from the process water.
