Title: Fine coal washability of Alaskan coals

Abstract

Technical problems involving sample pulverization and dispersion of solids during centrifugal float sink process have been solved. Work has been completed on seven samples. The seven represent five coal fields ranging in rank from subbituminous C to high volatile B bituminous. We are confident the system developed will work for all 50 samples needed to be processed under the grant. Results presented in the attached tables show washability analysis of samples crushed to 65 mesh, 200 mesh and 325 mesh sizes. Proximate and Ultimate analysis of 1.6 Float and Sink products of samples crushed to 325 mesh are also presented. With the exception of major oxide analysis of 1.6 float and sink products work on the seven samples is complete. We are awaiting installation of our newly purchased Spectraspan V ICP/DCP system for completion of this phase of the program. 11 tables.
