· Leaching process. The major species of uranium compounds in coal ash were U 3 O 8 and Ca(UO 2)O 2, which were easily dissolved by sulfuric acid [Eqs. (1, 2, 4)].It is wellknown that the U 6+ is more stable and easier to migrate from previous uranium compounds to the sulfuric acid. On this basis, oxidants had the ability to oxidize the remnant reducing substances and also enhanced the ionic ...

· The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact and grind the material in the cylinder to grind ...

Grinding of a high volatile bituminous coal was performed in three comminution devices: Raymond Mill (RM), Rolls Crusher (RC) and Ball Mill (BM). The pulverized samples were sieved to obtain four particle size fractions, and temp.programmed combustion (TPC) was used for the evaluation of their combustion behavior. In addn., three coals of different hardness and rank were mixed in various ...
