Laboratory Experiments in Electrokinetic Densification of Mill Tailings (In Two Parts). 2. Application to Various Types and Classifications of Tailings.
NTIS: PB 234 062 :43 pages
This report describes Bureau of Mines laboratory test results in electrokinetic dewatering and consolidation of metal-mine mill tailings from five mines in the Coeur d'Alene, Idaho, District. Classified (coarse) tailings, slimes, and unclassified material were separately tested. Tailings were placed in 0.3-Ft3 plexiglass models, and DC potential was applied until dewatering ceased. Time- oriented measurements of water removal, changes in resistivity, and power consumption were recorded during the dewatering process. Moisture content and density of the dewatered material at test end indicated the method to be generally effective for all materials examined, but best results were achieved with well-mixed unclassified tailings.
