(A) also known as the leaching residue. Uranium ore (or ore) in acid or alkali leaching process of leaching is not acid or alkali leaching of that part of the mineral. Due to the selective leaching process, most of the gangue minerals remain in the slag. There were also some have been acid leaching into the solution of the impurity ions (eg Fe3 +), due to lower acidity of leaching solution, but also the hydrolysis precipitation into the slag being undone. In order to prevent leaching of uranium into the solution hydrolysis, leaching solution must maintain a certain amount of excess acid.
  (B) molten blast furnace slag in the sudden cold, too late to form a glassy crystalline material. Was thin granular. Molten slag directly into the cooling pond known as water-quenching slag, commonly known as the water residue. After grinded slag, the activity of cement mixed material. SiO2 slag containing more acidic slag, containing Al2O3 and CaO and more for the basic slag. The activity of alkaline than acidic slag slag higher. Slag due to the water itself has a certain hard, not long-term storage. Slag
