THE MINES MAGAZINE • AUGUST, 1960 .9 8 THE MINES MAGAZINE • AUGUST, 1960 Low-Ash Coal Product Produced At present most coal preparation is aimed at pro­ ducing a uniform low-ash product. The future will probably see many changes in the specifications for coal for special uses. The future may also require utilization of lower grade coals where only the best are used now. We have already seen thc market change from a time when lump coal was preferred and the fines were discarded or sold at a low price to the present when lump coal has only a limited Preparation market and tlie finer sizes are in greater demand. It was with these changes in mind that the author began research in the selective preparation of coal. Let us now go back for a minute to the treatment of metallic ores. In treating an ore we concentrate Of Coal the valuable materials in one product and the waste • Figure 2. Mineral Material in Coal: a. Semifusinite; b. Caicite; c. Pyrite; d.
