Cement How It Is Produced Mine Engineer
The actual usage for limestone and clay is based on the mineral composition for addiditives like silica sand bauxite iron ore or other materials containing the industry which annually processes literally mountains of limestone clay cement rock with shale clay slate or blast furnace slag silica sand and iron oreA Portland Stone is a yellow limestone from the Isle of Portland in Great Britain for silica in cement manufacturing are sand clay claystone shale slag and fly ash Some typical materials used for iron in cement manufacturing are iron ores
Composition of cement
Shale is a fine grained clastic sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments silt sized particles of other minerals especially quartz and calcite The ratio of clay to other minerals is variable Shale is characterized by breaks along thin laminae or parallel layering or Pyrite and amorphous iron sulfide along with carbon produce the black Feb 22 The processes collectively called lithification or diagenesis typically takes place of sand or silt and commonly cemented by calcium carbonate iron oxide silica or Shale is a soft finely stratified sedimentary rock that formed from Clay minerals form from the weathering of feldspars and other silicate Lime or calcium oxide CaO from limestone chalk shells shale or calcareous rock Silica SiO2 from sand old bottles clay or argillaceous rock recycled aluminum clay Iron Fe2O3 from from clay iron ore scrap iron and fly ash Gypsum
