    Float-Sink (Washability) Test, Coal Analysis,

    Float-sink tests are done on samples of coal from beds that will likely need washing (beneficiation, preparation) to remove sulfur or ash (rock and mineral matter) from the coal to meet the desired specifications of the end user.The float-sink analysis determines how much coal can be separated from rock and minerals in fluids of different densities.

    Coke (fuel) - Wikipedia

    Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low

    DETERMINATION OF THE WASHABILITY OF

    Coking coal must also have low sulphur and phosphorous contents. Almost all metallurgical coal is used in coke ovens. The coking process consists of heating coking coal to around 1000-1100ºC in the absence of oxygen to drive off the volatile compounds (pyrolysis). This process results in a hard porous material - coke. Coke is produced in a coke battery which is composed of many coke ovens

    Prime coking coals are usually more expensive than other coals, e.g., Generally, washability of LVMC coal can be improved by crushing it to smaller size. The difficult washability characteristics of LVMC coals are due to fine dissemination of mineral particles with macerals. The ash % of marketable product can be further improved by blending with prime coking coal, so that this coal can be

    The results of washability data are indicated in Fig. 10.5. It gives the sulphur content of that raw coal size for each density fraction. The fractional sulphur content is at a peak at 1.5 relative density (RD). It can be also seen from the same figure that the cumulative sulphur content is reduced to some extent at cut-off points below 1.3 RD.
