Abstract |
The report gives results of a characterization of the fine solid constituents of coal preparation plant waste water, to provide a better understanding of how to treat the water for recycle or discharge. Thirteen waste water samples, obtained from coal preparation plants throughout the U.S., were analyzed for: identification and quantification of solid constituents, size analysis of solids, and surface properties of the solids. The study concluded that: (1) Eastern and Western coal region samples can be distinguished on the basis of mineralogy and size distribution of the solid particles; (2) the carbonaceous material of Eastern coals averages 60% of the blackwater solids, and the remaining 40% consists of clay minerals, quartz, calcite, and pyrite; and (3) virtually all of the carbonaceous material in Eastern plant waste waters can be removed by froth flotation, with the product containing 11% mineral matter. |
