✦ Synopsis

0 1 Solid fuels (preparation) compared to the use of water-only for the treatment of an easy-to-clean Illinois No. 6 fine coal sample. For a difficult-to-clean coal, the mass yield improvement was significantly greater at nearly 20% by wt. From the treatment of four different coal samples, organic efficiency values greater than 90% were obtained over the entire range of product quality values. These findings are reflective of the highly efficiency, low density separations provided by the sense-medium as indicated by probable error values below 0.05.

Application of petroleum-coke fines for preparation of blast-furnace coke Pishnograev, S.N. Ed al. St&, 1999, 11, 7-9. (In Russian) Petroleum-coke fines containing 0.29-0.4% ash and 2.3-2.6% S were evaluated as an additive in the manufacture of lump coal-derived coke for blast-furnace smelting of Fe ores. Addition of the low-cash petroleum coke fines decreased the ash content of the smelting coke, but increased the S-impurity content in the coke and in the molten pig iron product. The optimized addition of 5% fines did not require major changes in the coke manufacture or Fe-ore smelting.
