Ngā Kupu Matua: whakakoi, alumina, ātete-hau, uku
Ko te alumina parauri he momo rauemi whakakoi hangai e hangaia ana mā te whakakotahi i te bauxite me ētahi atu rauemi i roto i te oumu hiko. He tino pakeke, he pakari hoki, e pai ai mō ngā momo mahi ahumahi.
Ko ngā whakamahinga matua o te alumina parauri kua whakaranua ko:
• Hei rauemi whakakoi mō te pupuhi onepu, te huri, me te tapahi.
• Hei rauemi ātete ahi mō te whakapuru i ngā oumu me ētahi atu taputapu pāmahana teitei.
• Hei rauemi uku mō te whakaputa hua āhua, hua kore āhua rānei.
• Hei rauemi paninga mō te whakarite whakarewa, ngā papa whakanikoniko, me ngā peita.
He rerekē ngā ihirangi o te BFA, pērā i te 95%, 90%, 85%, 80% me te ōrau iti iho.
Ka teitei ake te ōrau, ka teitei ake te parakore me te pakeke o te rauemi. Tērā pea ka pā tēnei ki te tae, te rahi, me te whakamahinga o te rauemi.
He mā, he mā-parauri rānei te tae o te alumina parauri kua hanumihia ki te 95%, ko te alumina parauri kua hanumihia ki te 90% ia he parauri, he parauri rānei te tae. Nā ngā poke kei roto i te rauemi, pērā i te waikura titanium me te waikura rino.
Ko te alumina parauri kua whakaranua 95% e whakamahia ana i roto i ngā wira huri me ngā taputapu tapahi mahi-teitei, ko te alumina parauri kua whakaranua 90% ia e whakamahia ana i roto i ngā wira huri, te pepa kirikiri, me ētahi atu hua whakakoi. Ko te teitei ake o te parakore, ko te teitei ake o te ātete ki te pakū o te rauemi.
He hanganga tioata hexagonal tō te alumina parauri hanumi 95%, ko te alumina parauri hanumi 90% ia he hanganga tioata trigonal tō te alumina parauri hanumi. Tērā pea ka pāngia te rahi me te āhua o ngā matūriki e ngā hanganga tioata rerekē.
