Abstract
The Bureau of Mines is conducting research on a novel method for dewatering coal-clay waste as an alternative to ponding now being practiced by the industry. The method consists of mixing coal-clay waste with a flocculant, polyethylene oxide (peo), and dewatering the resulting flocs in a hydrosieve screen. The technique is being tested in a unit operating at 400 gal/min, located at the Jim Walter's No. 7 Mine in Brookwood, Alabama. In continuous tests, coal- clay waste has been dewatered from a nominal 3 pct solids to products ranging from 50 to 60 pct solids. When placed in a pit, the dewatered material continues to consolidate to 70 pct solids in several days.
