Limited Field Tests in Electrokinetic Densification of Mill Tailings.
NTIS: PB 243 652 :47 pages
Extensive Bureau of Mines laboratory testing has shown that electrokinetic densification can be an effective method for dewatering and consolidating unclassified metal mine mill tailings. The report describes results of a limited field test of this technique. Eighteen-cubic-yard concrete model stopes, 18 feet long by 6 feet deep by 56 inches wide, were filled with unclassified tailings slurry from a metal mine in the Coeur d'Alene, Idaho, District. Five different tests were performed. They showed that a strong, dense, dewatered fill can be obtained in a reasonably short time using electrokinetics, with typical power consumption of 25 to 30 kw-hr/yd3 of densified fill. At present power costs in the Coeur d'Alene District, this would amount to 10 to 12 cents/yd3.
