Coal dust has historically been collected as a waste product from homes and industry. During the nineteenth century coal ash was taken by 'scavengers' and delivered to local brick works, where the ash would be mixed with clay.
The process is same as making cement in cement factories whereas the clay and limestone are burnt with coal and gypsum. And it is mixed and ground to cement. In fly ash mix also the fly ash, which is burnt clay particles (oxides of clay) obtained from burning coal, which contains clay from the mines.

Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure .
Upper Delong Coal (western Illinois).—A coal of the upper Tradewater formation, above the Curlew sandstone with a persistent clay parting, suggesting the Fire Clay coal of eastern Kentucky, of which it may be the equivalent (Wanless, 1939).
Coal Combustion Products in Constructed Landfills Characteristics, Beneficial Use, Disposal, & Impact on Geocomposite Leachate Collection Systems
Coal has a wide moisture content range, which affects its value as fuel and determines how environmentally friendly it is to use. Without the proper handling and production processes, the quality of coal is depleted, potentially causing increased pollution.

Clay County is located in central West ia, northeast of Charleston. It occupies 346.4 square miles. The Elk River bisects the county from east to west, entering at Duck and leaving at King Shoals. The town of Clay is the county seat.. Rugged, laurel-covered hollows dart back from the narrow river valley, and level land is at a premium.
Coal. Coal is a naturally occurring combustible material consisting primarily of the element carbon. It also contains low percentages of solid, liquid, and gaseous hydrocarbons and/or other materials, such as compounds of nitrogen and sulfur.

Stabilization of Soil with Self-Cementing Coal Ashes Scott M. Mackiewicz,1 E. Glen Ferguson,2 1 & 2Kleinfelder, 7802 Barton, Lenexa, Kansas 66214 KEYWORDS: Class "C" fly ash, self-cementing, soil stabilization, pavement subgrades INTRODUCTION The combustion of subbituminous coals in electrical generating units produces a fly ash that has
The sections in Fig. 10 reveal that the clay content analyses determined in each hole are highly correlatable and that subtle nuances in the clay content can be tracked through the model. As expected, each coal seam is represented by intervals with low-clay contents and the clay band above the main seam (elevation of minus 2 m on the left of ...

Coal is a sedimentary black or dark brown rock that varies in composition. Some types of coal burn hotter and cleaner, while others contain high moisture content and compounds that contribute to acid rain and other pollution when burned.

Molding sand, also known as foundry sand, is a sand that when moistened and compressed or oiled or heated tends to pack well and hold its shape. It is used in the process of sand casting for preparing the mould cavity.. Green sand. Green sand is an aggregate of sand, bentonite clay, pulverized coal and water.Its principal use is in making molds for metal casting.
