Mineralogy, Structure, and Green Processing of Clay Minerals

Mineralogy, Structure, and Green Processing of Clay Minerals 

Plastic natural ceramic raw materials, consisting predominately of kaolinite, illite and/or montmorUlonite, are accompanied by residual quartz, feldspar, mica, and calcite as well as organic residues. In particular, the hmestone content has been used to distinguish between clay ( 4 mass% hme), marly day (4—10 mass% lime), clayey marl (10-40 mass% hme), marl (40-75 mass% hme), calcareous marl (75-90 mass% lime), marly hmestone (90-96 mass% hne), and hmestone ( 96 mass% hme). Kaolinitic raw materials formed in situ (autochthoneous) are called kadine, while kaolinitic raw materials found in secondary deposits (aUochthone-ous) are called clays. Marl and marly hmestones are important raw materials for Portland cement production (see Section 5.2.1).
