摘要:
The invention relates to a process for improving the sedimentation and filtering properties of waste waters and/or slurries and muds containing clay minerals. The waste waters and/or slurries obtained in the various technologies and containing clay minerals and optionally also other solid components are treated with compounds containing ions having a hydrated ionic diameter of from 0.12 to 0.15 nm and a co-ordination number of 12.
