Ko te paru whero he para ahumahi poke e puta mai ana i te bauxite i te tukanga whakaputa alumina. He whero, he whero pouri, he hina rānei te āhua o te paru nā te rerekētanga o te nui o te waikura rino. He nui te wai, ā, kei roto ngā wāhanga kino pēnei i te kawakore me ngā konganuku taumaha. Ka huri hei mate mau tonu e pā ana ki te taiao. Ko ngā wāhanga matua o te paru whero ko te SiO2, Al2O3, CaO, Fe2O3, me ētahi atu, ā, he nui ngā matū kawakore kei roto. Ka taea e te uara pH te eke ki runga ake i te 11, he tino kawakore. I te mea ka iti haere te bauxite kounga teitei o tōku whenua, ka taea e te nui o te paru whero e tukuna ana mai i te whakaputanga o te 1 tana o te alumina te eke ki te 1.5-2 tana.
E ai ki ngā raraunga mai i te Tari Tatauranga ā-Motu, ko te putanga alumina a Haina i te tau 2021 ka eke ki te 77.475 miriona tana, he pikinga tau-ki-te-tau o te 5.0%. Mēnā ka tatauhia i runga i te tukunga o te 1.5 tana o te paru whero mō ia tana o te alumina, ko te tukunga o te paru whero i te tau 2021 anake ka eke ki te 100 miriona tana, ā, ko te reiti whakamahinga whānui o te paru whero i tōku whenua he 7% noa iho. Ko te kohikohinga o te paru whero ehara i te mea ko ngā rauemi whenua anake. Mēnā kāore i te whakahaeretia tika, ka puta mai hoki ngā mōrearea pēnei i te pakaru o te tāke o te puna paru whero, te parahanga o te oneone me te wai, me ētahi atu. Nō reira, he mea nui kia tere te whakamahi i te paru whero.
He maha ngā momo konganuku utu nui kei roto i te paru whero, tae atu ki te rino, te konumohe, te titanium, te vanadium, me ētahi atu, ka taea te hangarua hei rauemi pea. Ko te wāhanga papatipu o te Fe2O3 i roto i te tukanga paru whero a Bayer he nui ake i te 30%, koinei te wāhanga matū matua o te paru whero. I ngā tau tata nei, kua mahi tonu te Kamupene Huate i ngā rangahau me ngā rangahau mō te wehenga paru whero, ā, kua whakawhanakehia he huinga hangarau katoa mō te wehenga o te paru whero rino me te paura pai. , 40% ki te 50% o ngā kohuke rino i roto i te paru whero ka taea te whakahoki mai mā te tukanga whakapai ake i te aukume ngoikore me te tukanga whakapai ake i te aukume kaha e rua, ā, kua mahia ngā tono ahumahi nui ki Shandong, Guangxi, Guizhou, Yunnan me ētahi atu rohe. He pai ngā tohu. Ko te whakahokinga mai o ngā konganuku utu nui i roto i te paru whero ehara i te mea ka taea anake te hanga painga ōhanga, engari ka taea hoki te whakaora rauemi me te whakaiti i te pēhanga taiao.

Ko te "Mahere Whakatinanatanga mō te Whakateretere i te Whakatairanga i te Whakamahinga Whānui o ngā Rauemi Ahumahi" i whakaputaina tata nei e ngā tari e waru tae atu ki te Manatū Ahumahi me te Hangarau Mōhiohio me te Manatū Taiao me te Taiao, i whakatakoto i ngā whakaritenga mārama mō te reiti whakamahinga whānui o ngā para totoka ahumahi nui i te wā o te "Mahere Tau Rima 14". Heoi, mō te whakamahinga whānui o te paru whero, ko te "Whakapaipai Whai Hua" anake e hiahiatia ana. Nā te mea he uaua ki te tango i te matū kawakore i konatunatua ki te paru whero, ā, he nui te ihirangi, ā, kei roto hoki te fluorine, te konumohe me ētahi atu poke. He uaua tonu te whakamahi kino o te paru whero, nō reira he raruraru tonu te whakamahinga whānui o te paru whero puta noa i te ao. . Karanga atu ki ngā wāhanga rangahau pūtaiao e tika ana kia haere tonu te rangahau hohonu me te hangarau whakamahinga whānui o te paru whero o nāianei hei whakanui ake i te whakamahinga whānui o ngā rauemi paru whero.
