metallurgy chemical kiln and lime kiln according to different materials. Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. Metallurgy chemical kiln is used in metallurgy industry and ironworks for lean iron ore‚ chromium ore and ferronickel ore calcination‚ which is used for calcining of high aluminum vandal ochre in refractory material industry; for calcining of calotte and aluminum hydroxide in aluminum manufacturer; for calcining of chrome sand ore

are all Essential for life. Myoglobin contains a porphyrin ring with an iron center .a proximal histidine group was attached directly to the iron center‚ and a distal histidine group on the opposite face‚ not bonded to the iron. In hemeoglobin‚ an iron held in a porphyrin ring. The porphyrin ring consists of four pyrrole molecules cyclically linked together‚ by methene bridges‚ with the iron ion bound in the center.[2] The iron ion‚ which was the site of oxygen binding‚ coordinates with the four nitrogens
