Hei tētahi o ngā konganuku tawhito rawa atu, ā, he mea nui te rino hei rauemi mata mō te hanga rino me te maitai. I tēnei wā, kei te mimiti haere ngā rauemi rino, e tohuhia ana e te nui ake o te ōwehenga o te konganuku kikokore i te konganuku momona, he nui ake ngā konganuku e pā ana, me ngā hanganga konganuku uaua. Ko te rino ka tangohia mai i tana konganuku, e mōhiotia ana ko te hematite, ko te magnetite rānei, mā te tukanga e kiia nei ko te whakapai ake i te konganuku rino. Ka rerekē pea ngā mahi motuhake e uru ana ki te tango rino ā-umanga i runga i te āhua o te konganuku me ngā hua e hiahiatia ana, engari ko te tukanga whānui ko ngā wāhanga e whai ake nei:
Te maina
Ka kitea tuatahitia ngā putunga rino mā roto i ngā mahi tūhura. Kia kitea he putunga e tika ana, ka tangohia te rino mai i te whenua mā te whakamahi i ngā tikanga keri pēnei i te keri tuwhera, i te keri raro whenua rānei. He mea nui tēnei wāhanga tuatahi nā te mea ka whakatakoto i te atamira mō ngā tukanga keri e whai ake nei.
Te kuru me te huri
Kātahi ka kuruhia te konganuku kua tangohia kia iti ake hei whakahaere i te tukatuka. Ko te tikanga o te kuru he whakamahi i ngā mīhini kuru kauae, i ngā mīhini kuru kōne rānei, ā, ko te huri ka mahia mā te whakamahi i ngā mira huri aunoa, i ngā mira pōro rānei. Mā tēnei tukanga ka whakaitihia te konganuku kia rite ki te paura angiangi, kia māmā ake ai te whakahaere me te tukatuka i ngā wāhanga e whai ake nei.
Wehenga Aukume
He maha ngā wā kei roto i te rino he paru, he kohuke rānei me tango i mua i te whakamahinga ki te hanga rino me te maitai. Ko te wehenga aukume he tikanga noa e whakamahia ana hei wehe i ngā kohuke aukume mai i ngā mea kāore i te aukume. Ka whakamahia ngā aukume kaha, pērā i te wehewehe aukume Huate, hei kukume me te wehe i ngā matūriki rino mai i te gangue (ngā rauemi kāore e hiahiatia). He mea nui tēnei taahiraa hei whakapai ake i te parakore o te kohuke.
Te Whakawhiwhinga
Ko te mahi e whai ake nei ko te whakapūmau i te maitai, ko te whāinga he whakanui ake i te nui o te rino mā roto i ngā tikanga maha. Tērā pea ka uru atu ki tēnei tukanga te horoi, te tātari, me ngā tikanga wehewehe ā-papa hei tango i ngā poke me te whakapai ake i te kounga o te maitai. Ka uru atu hoki ki te whakapūmau te whakapūmau, te tāpiri i ngā matū ki te maitai hei whakapūmau i ngā matūriki rino, hei wehe atu i te toenga o te rauemi.
Te Whakapūpū, te Whakapūpū rānei
Kia oti te whakangao i te konganuku, me whakakotahi pea ngā matūriki angiangi ki ngā matūriki nunui ake kia pai ake ai te tukatuka. Ko te whakangao matū ko te hanga i ngā matūriki porowhita iti mā te huri i te konganuku ki ngā tāpiringa pēnei i te kōhatu, te bentonite, te dolomite rānei. Ko te whakangao matū, i tētahi atu taha, ko te whakamahana i ngā matūriki konganuku me ngā hau me te hau kōka hei hanga i tētahi papatipu haurua-whakakotahi e mōhiotia ana ko te sinter. Mā ēnei tukanga ka whakarite te konganuku mō te mahi tango whakamutunga mā te whakapai ake i ōna āhuatanga ā-tinana me ōna āhuatanga whakahaere.
Te whakarewa
Ko te taahiraa whakamutunga o te tukanga tango ko te whakarewa, ka whakamahanahia te rino i roto i te oumu pupuhi me te kōke (he wahie waro) me te kōhatu (e mahi ana hei rere). Ka pakaru te rino i te wera nui hei rino rewa, ka kohia ki raro o te oumu, me te para, ka mānu ki runga ka tangohia. Kātahi ka makahia te rino rewa ki ngā āhua rerekē, pērā i ngā poro, i ngā pire rānei, ā, ka tukatukahia anō kia whiwhi ai i ngā hua rino me te maitai e hiahiatia ana.
He mea nui kia mōhiotia he rerekē pea ngā tukanga motuhake e whakamahia ana i ngā putunga rino me ngā whare tukatuka rerekē, engari he rite tonu ngā mātāpono whānui. He tukanga uaua, he maha ngā taahiraa te tango rino mai i te rino, e hiahia ana kia āta whakahaerea ngā rauemi me te hangarau. Mā te whakaurunga o ngā taputapu matatau pēnei i te wehewehe aukume Huate ka whakarei ake i te whai huatanga me te kounga o te tukanga wehenga, kia tino tutuki ai te hua whakamutunga i ngā paerewa e hiahiatia ana mō te hanga rino me te maitai.
