Abstract
A sample of high-volatile a bituminous coal consisting of cuttings from multiple auger holes was taken from a stripped segment of a 5.3- Foot coalbed at the now idle Castle Mountain Mine, Matanuska coalfield, Alaska. The sample was shipped to the Bureau of Mines Denver Coloradoal Research Laboratory where studies of its coking properties were made. The ash content of the sample was reduced by float and sink methods from 16.5 percent to 10.4 percent. After bench scale tests indicated good coking qualities for the "cleaned" coal, three 50-pound coking tests were conducted. Coke from the unblended coal was strong and seemed of foundry quality. Using 30 percent of Castle Mountain as a blending coal with a Utah base coal produced a coke with reasonably good characterisitcs.
