There's some calcining around the edges.

These emissions are generated in the kiln and preheating/pre-calcining operations.

The radius, ulna, thorax and anterior plane of the lower extremities all calcined from the fire.

Mercury is introduced into the kiln with fuels such as coal and oil which are used to provide energy for calcination and sintering.

Conversion of uranium ore concentrates to UO3 can be performed by first dissolving the ore in nitric acid and extracting purified uranyl nitrate using a solvent such as tributyl phosphate. Next, the uranyl nitrate is converted to UO3 either by concentration and denitration, or by neutralization with gaseous ammonia to produce ammonium diuranate with subsequent filtering, drying, and calcining.

- Building materials industry: New dry-process kilns with pre-calcinator technology should be developed in the cement industry; energy-efficient grinding equipment and power-generating technology should be promoted through the use of waste heat recovered from cement kilns; the performance of existing large- and medium-size rotary kilns, mills and drying machines should be improved with a view to energy conservation; and mechanized vertical kilns, wet-process kilns and long dry-process kilns and other outdated cement-production technologies should be gradually phased out.
