Chapter 4 Classification of Bauxites ScienceDirectExtraction Process of Aluminium from Bauxite Ore

Chapter 4 CLASSIFICATION OF BAUXITES SOILS AND WEATHERED ROCKS Classijicat ion Enrichment of aluminium may take place in various tropical and subtropical soil types on different source rocks The most important soils are latosols and undosols respectively which may differ in character depending on local conditionsAlumina Extraction Problem In the standard Bayer Process for refining bauxite to produce alumina the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch

The Classification of Bauxites from the Bayer Plant StandpointBauxite Refining Subcategory Of The Aluminum Segment Of

Abstract The mineralogy chemical composition and physical characteristics of different bauxites which are mined and processed today reflect associated rock types tectonics and other geological factors associated with the different deposits and provide a basis for their classification into distinct groups from the standpoint of the Bayer alumina plantBecause of this growth pattern aluminum is one of the youngest metal industries and very few plants either primary aluminum or bauxite refining are more than 30 years old Bauxite is the principal ore of aluminum and the only one used commercially in the United Stat
