Bauxite (bauxite ore) e faasino i se faaupuga tuʻufaʻatasia mo minerale e mafai ona faʻaaogaina i alamanuia, e masani lava ona aofia ai le gibbsite, boehmite, poʻo le diaspore. Ose punaoa e le mafai ona fa'afouina. Bauxite mama e pa'epa'e le lanu ma e mafai ona foliga efuefu malamalama, lanu meamata, po'o le mumu mumu ona o mea leaga eseese. O le Bauxite o loʻo i ai le tele o faʻaoga faʻapisinisi. I le tasi itu, o le mea autu autu mo le gaosia o le alumina, lea e maua ai le alumini. I le isi itu, o loʻo faʻaaogaina lautele e avea o se mea mataʻutia i alamanuia e pei o mea refractory, fused corundum, mea olo, oloa sima, vailaʻau vailaʻau, ma maualuga alumina slurry.

 

calcined bauxite o lo'o i ai le alumina fa'asao ma le alumini hydroxide, e maua e ala i le fa'amamaina o le bauxite maualuga i le maualuga o le vevela (85°C i le 1600°C) i totonu o se kiln rotary. O se tasi lea o mea mataʻina autu mo le gaosia o le alumini. Pe a faatusatusa i le uluai bauxite, pe a uma ona aveese le susu e ala i le calcination, o le alumina anotusi o le calcined bauxite e mafai ona faateleina mai le tusa ma le 57% i le 58% o le uluai bauxite i le 84% i le 88%.

Talosaga

 

  1. Alumini alamanuia: bauxite o loʻo i ai tulaga maualuga alumini ma o se mea mataʻutia taua mo alamanuia faʻafefe alumini;
    2. Tu'u sa'o: e mafai ona faia le bauxite i ituaiga eseese o fa'ameamea pe'ā uma ona fa'agaioiina, fa'aaoga masani i feso'ota'iga, meafaigāluega, masini ma meafaigaluega;
    3. Refractory mea: bauxite o loʻo i ai mea lelei e pei o le faʻalauteleina o le vevela, maualuga le maualuga, ma le maualuga o le maualuga o le vevela, ma avea ai ma mea masani masani mo mea faʻafefe. Refractory mea e faia i ai e masani ona faʻaaogaina i uʻamea, metallurgy e le o ferrous, suauu, vailaʻau ma isi fanua tau alamanuia.
    4. Mea faufale: e mafai ona faʻaleleia le malosi ma le maʻaʻa o mea e pei o le sima, sima, ma le sima le paʻu o le bauxite, aʻo faʻaleleia foi lo latou tumau ma le faʻafefe.
