Bauxite ALS

bauxite in the Bayer process is called the Total Available Alumina TAA It is made up of two parts • THA Trihydrate Alumina This is the alumina that is extracted in a low temperature refinery • MHA Monohydrate Alumina This is the extra alumina that will be extracted in a high temperature plant The relationship can be simply expressed as TAA = THA MHA Similarly not all of
