ABSTRACT:
Method and apparatus for dewatering mill tailings, slimes and slurries, wherein ultra fine particles materially reduce the rate of natural dewatering and hinder their disposal in the mining and processing of phosphate, coal, potash, uranium, talc and the like. The invention is preferably carried out in a closed loop system involving the use of electrokinetic densification and substantially continuous decanting of the supernatant.
