nature : cement kiln flue gas with the fine dust trapping been kiln dust down. Because cement batching containing different forms of potassium aluminum silicate minerals, such as potassium feldspar, mica, the high temperature sintering process, the volatile potassium, and potassium as fine grain with smoke emission. So recycling kiln dust containing potassium elements would be used as a fertilizer, potash fertilizer called kiln dust. Greyish yellow or brown powder. Very small particles.
