How is Mercury Monitored in a Cement Kiln? - Advancing Mining

Cement kilns are large furnaces used to grind and heat a mixture of raw materials (like limestone, clay, and iron ore) to produce cement. As you can imagine, that process takes a lot of energy - as can be seen by the large smokestacks that tower over the plants. As the various fuels are burned and the materials heated, air toxics are emitted.
