Preparation tests of lignite from a deposit near Toledo, Lewis County, Wash

OSTI ID:7311176
Strip mining offers attractive means of augmenting coal production because it requires less manpower and less time for development. Any coal property amenable to stripping warrants examination. Bureau of Mines examined one such property--a lignite deposit near Toledo, Wash. Hand-picking and washing tests showed that a coal containing about 33 percent moisture and 12 to 17 percent ash could be produced, and that such a coal could be used as low-cost fuel in a suitably equipped boiler plant near the mine. However, the low calorific value of the coal makes it unsuitable for shipment to more distant consumers.
