Lime Kiln Dust / Calciment ® LKD is a coproduct of lime manufacturing. Lime is created when high quality, natural deposits of limestone, or calcium carbonate (CaCO3) is subjected to extreme heat. Once crushed and sized, the limestone is fed into kilns where it is calcined, or basically cooked, at temperatures as high as 2000 degrees Fahrenheit.
