He konganuku kore-whakarewa nui te nikara, ā, he whānuitia ngā whakamahinga. Ko te nuinga o te wā ka kitea i roto i ngā konganuku nikara whanariki me te nikara waikura i te taiao. 30% o ngā rauemi nikara he konganuku whanariki, ā, 70% he konganuku nikara laterite. I te pikinga ake o te hiahia mō te nikara me te hekenga haere o te konganuku nikara whanariki, e whakaatu ana te whanaketanga o te konganuku nikara laterite i tētahi ia tere. I roto i te tukanga o te pirau waikawa whanariki o te konganuku nikara laterite, kua noho te toenga para o te konganuku nikara laterite hei take e aukati ana i te tukanga tango nikara mākū. Hei kaihanga opara nikaramira huri poutū, ka whakaatuhia e HCMilling (Guilin Hongcheng) ngā tikanga whakaora me te whakamahi anō i te para o te nikara laterit ki a koe i raro nei.

Ko te tikanga whakaora me te whakamahi anō i ngā toenga para nikara lateriti ko te tahu i ngā toenga para nikara lateriti i te 160~900 ℃ mō te 20~120 meneti, ā, i muri i te whakamatao maori, ka hurihia kia paura me te toenga tātari 0.08 mm iti iho i te 10% mā roto. para nikaramira huri poutūhei whakarite i ngā rauemi mata o te sima konupora, te rauemi whakamaroke turanga rori, te putty peita pakitara whare rānei. Ko ngā mahi motuhake mō te whakaora me te whakamahi anō i te para o te nikara laterite koia ēnei:

(1) Ka whakamaroketia te para nikara me te ihirangi makuku o te 12% ~ 18% (ko ngā matūriki angiangi i raro i te 3 mm neke atu i te 70%, ā, he kaha te matotoru) mā te whakamaroke koropupū tere, ka whakaitihia te ihirangi makuku ki raro iho i te 3%, kātahi ka rongoatia i muri i te maimoatanga tango rino maha-wāhanga, ā, ka whakanohoia ngā kai ki roto i tepara nikaramira huri.

(2) Ka whāngaihia te para nikara maroke ki roto i te mira para nikara hei whakaputa me te kuru i muri i te puranga (me te tāpiri i te nui e tika ana o te whakaoho), kātahi ka wehea mā te wehenga hau. Ka whakahokia ngā matūriki matotoru ki tepara nikarapoutūroeramira, ā, ka uru te paura angiangi e toe ana ki te pūwero paura me te hau hei whakarite i te hua kua oti, kātahi ka rongoatia. Ko te paura matotoru me te horahanga mata motuhake o <200m2/kg ka whakahokia ki te mira huri poutū para nikara, kātahi ka kuruhia. Ko ētahi paura tino angiangi me te horahanga mata motuhake o >450m2/kg ka kohia e te pūwero puehu, kātahi ka haria tika ki te whare putunga hua kua oti.

Ko te para para nikara laterite he ranunga o te konupūmā whanariki, te konupūmā hauwaiwai, te konupūmā silicate hydrate me te konupūmā aluminate hydrate. I muri i te whakamaroke, i te whakapūkara rānei i te pāmahana iti, ka whiwhihia te ranunga o te konupūmā whanariki korewai, te konupūmā waikura, te dicalcium silicate me te konupūmā aluminate. He rite tonu ki te sima Portland, te sima magnesite me te gypsum. He momo rauemi sima hou tēnei, ā, he whānui te whakamahinga i roto i te umanga hanga. He māmā noa te tukanga whakaora me te whakamahi anō i te para nikara laterite, kāore e hiahiatia he pāmahana teitei, he pēhanga teitei me ngā rauemi utu nui, ā, he ngāwari ki te whakatinana. Ko te tukanga opara nikarapoutūroeramiraKo te taahiraa tino nui i roto i te whakaora, te whakamahi anō me te whakamahinga rauemi o te para nikara laterite, e tata ana ki te haurua o te katoa o te whakapaunga hiko, kia whakaitihia ai ngā utu whakaputa, te whakapaunga pūngao me te whakapai ake i te whai huatanga o te huri para nikara. Ka tūtohu mātou kia whiriwhiria e koe te mira huri poutū o te nikara hei whakakapi i te mira pōro tuku iho hei taputapu matua mō te whakaora me te whakamahi anō i te para nikara laterite. Ko tepara nikara tino paimiratukanga o para nikaramira huri poutū Ka whakamahia, ā, ka tutuki te pai o te hurihanga tika mā te whakarerekē tika i te whakarōpūtanga kia pai ai te whakaputanga o te paura tino pai me te horahanga mata motuhake e tutuki ana i ngā whakaritenga kaha me te mahi i raro i te iti o te whakapaunga hiko, kia kore ai e raru te nui o te paura pai, te nui rānei o te whakapaunga pūngao e puta mai ana i te āhuatanga hurihanga nui o te mira pōro tuku iho.

Para nikara raupapa HLMmira huri poutū I hangaia e HCMilling (Guilin Hongcheng) kua whakamahia whānuitia i roto i ngā momo hangarua para para me te hangarua hei whakaputa rauemi sima matomato, e whakarato ana i te tautoko taputapu pai mo te whakaora me te whakamahi anō i te para para nikara laterite. Mena kei a koe te hiahia mo te hangarua para nikara laterite me para nikaramira huri, whakapā atu ki a HCM mō ētahi atu taipitopito mō ngā taputapu.
