MERCURY IN THE CEMENT INDUSTRY
Mercury emissions are typically higher in kiln operations with the raw mill-off ("direct" operation) due to the missing adsorption capacity of the freshly ground particles in the raw mill. Periodic purging (bleeding) of cement kiln dust from the system is an efficient way to control and reduce mercury emissions.
