Electrokinetic Consolidation of Slimes in an Underground Mine
These tests demonstrated that electrokinetic treatment of underground slime deposits can sufficiently harden them to permit their removal or use as backfill. Therefore, slimes can be effectively utilized underground, either as part of unclassified tailings subjected to electrokinetic treatment in primary stopes, or as taken from slime sumps. It is hoped that ultimately all slimes can be used as backfill, thereby eliminating the need for their aboveground disposal. This could best be accomplished by dewatering unclassified tailings to a much greater extent--approximately 70 wt-pct solids--before placing them in primary stopes. Such thickened slurries respond exceptionally well to electrokinetic treatment; they are easily transported hydraulically, and segregate to only a negligible extent on placement. Electrokinetic hardening of these deposits could create a dense, high-modulus backfill that would provide greater support for mine walls, men, and equipment than is attained by the coarse classified sand now in use.
