rotary kiln for mgco3

Aug 01, 2017 Abstract. The decomposition behavior of siderite in rotary kilns has been insufficiently investigated up to now. In particular, the interaction of the two primary reactions calcination of the carbonate and oxidation of the wustite under the conditions in a rotary kiln are not known. Therefore, experimental investigations were carried out with a
