Coal balls are not made of coal; they are nonflammable and useless for fuel. Coal balls are calciumrich permineralised life forms, mostly containing calcium and magnesium carbonates, pyrite, and quartz. Other minerals, including gypsum, illite, kaolinite, and lepidocrocite also appear in coal balls, albeit in lesser quantities. Although coal balls are usually about the size of a man's fist ...

1999). Although grinding of CBA adds many good properties to concrete, it should be kept in mind that grinding is an expensive and time consuming process (Őzkan et al. 2007). Besides that, the quantity of coal bottom ash (CBA) to replace the cement for typical appliion is limited to 1520% by mass of the total cementitious material.
coking coal middlings were firstly ground by wetmilling in a ball mill with iron balls. Progressive release flotation tests of sized products (,, and < mm) were performed in comparison to the floatsink tests.
