All basic data acquisition relevant to characterization of the contract samples physically and chemically has been completed. Assessment of this data and inter-relationships with mineralogical characterization data is concurrently on-going, with final petrographic data acquisition for the contract to be affected during the next quarter. This remaining analytical work is the detailed maceral analysis of the Illinois No. 6 samples. Work during this quarter focused on coarse and fine coal heavy-media pilot-scale cleaning operations using a heavy-media drum separation and a heavy-media cyclone. Chemical and mineralogical effects produced by these tests are reported herein, completing Task 4 testing of the effects of laboratory pilot cleaning on mineral composition and distribution. Results for froth flotation, size by gravity, jigging, and tabling for this task have been previously reported. Also completed during the work period was the chemical characterization of the Illinois No. 6 slurry-fines sample. Mineralogical data for this sample were reported in Progress Report Number 9.
