Bauxite Crushed Alumina
ALUMINA PRODUCTION Bauxite is crushed dried and ground in special mills where it is mixed with a small amount of water This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites The ore is loaded into autoclaves and treated with lime–caustic soda Live Chat; Briefly on the production 1 Milling The bauxite is washed and crushed, reducing the particle size and increasing the available surface area for the digestion stage Lime and "spent liquor" (caustic soda returned from the precipitation stage) are added at the mills to make a pumpable slurry 2 DesilicationMining and Refining – Process World AluminiumIn an alumina refinery bauxite is processed into pure aluminium oxide (alumina, or Al 2 O 3), which is the main raw material required for production of primary aluminium The Bayer process extracts alumina by caustic digestion of crushed bauxite at high temperature and pressure in an autoclave, followed by clarification, precipitation, washing and finally calcination to produce bauxite crushed alumina domainedelavierefr
