Alumini mā kua hanumime te alumina parauri kua whakaranua he mea whakakoi e rua e whakamahia whānuitia ana. He tokomaha te hunga kāore e mōhio ki te rerekētanga tika i waenga i ngā mea e rua engari ko te tae anake. Nā, māku koe e ārahi kia mārama.
Ahakoa kei roto i ngā mea whakakoi e rua te alumina, neke atu i te 99% te nui o te alumina o te alumina mā kua hanumi, ā, neke atu i te 95% te nui o te alumina o te alumina parauri kua hanumi.
Alumini mā kua hanumika hangaia mai i te paura alumina, ko te alumina parauri ia kei roto ngā kongakonga anthracite me te rino, me te bauxite kua whakakāhia. Ko te alumina mā kua whakakāhia he pakeke ake e whakamahia ana e ētahi kaiwhakamahi matatau, nā te mea he kaha tapahi pai ake, he pai hoki te oro, ā, ko te nuinga o te wā ka whakamahia mō te maitai waro, te maitai koranu, te maitai hanga, te parahi mārō, me ētahi atu. Whakamahia te alumina mā kua whakakāhia hei huri kia pai ake te kiko me te kanapa,
E whakamahia ana te alumina parauri kua whakaranua ki te mākete nui, ā, ko te nuinga o te wā e whakamahia ana mō te maitai kua tineia, te maitai tere-tiketike, me te maitai waro-tiketike hei tango i ngā kohao i runga i te mata, ā, kāore te pānga huri i te kanapa pērā i te alumina mā kua whakaranua.
