He kohuke uku noa te kaolin i te ao tūroa. He kohuke whai hua tēnei mō te tae mā, nō reira, he tohu nui te mā e pā ana ki te uara o te kaolin. Kei roto i te kaolin te rino, te mea rauropi, te mea pouri me ētahi atu poke. Mā ēnei poke ka rerekē te tae o te kaolin, ka pā ki te mā. Nō reira, me tango e te kaolin ngā poke.
Ko ngā tikanga purenga noa o te kaolin ko te wehenga ā-papa, te wehenga aukume, te whakapūmau, te maimoatanga matū, me ētahi atu. Ko ngā tikanga purenga noa o te kaolin ēnei:
1. Te wehenga ā-papatipu
Ko te tikanga wehewehe taumaha te nuinga o te wā e whakamahi ana i te rerekētanga matotoru i waenga i te kohuke gangue me te kaolin hei tango i ngā poke matotoru o ngā mea waro māmā, te quartz, te feldspar me ngā huānga kei roto te rino, te titanium me te manganese, kia whakaitihia ai te awe o ngā poke ki te mā. Ko ngā pūwero whakapūmau he mea whakamahi hei tango i ngā poke matotoru. Ka taea hoki te whakamahi i te rōpū hydrocyclone hei whakaoti i te horoi me te tirotiro i te kaolin i roto i te tukanga whakarōpū, e kore e taea anake te whakatutuki i te kaupapa o te horoi me te whakarōpū, engari ka tangohia hoki ētahi poke, he uara tono pai.
Heoi, he uaua ki te whiwhi hua kaolin whai tohu mā te tikanga wehenga anō, ā, me whiwhi ngā hua whai tohu whakamutunga mā te wehenga aukume, te whakapūngoi, te whakapūngoi me ētahi atu tikanga.
2. Wehenga aukume
He iti noa te rino kei roto i te nuinga o ngā konganuku kaolin, ko te 0.5-3% te nuinga, ko te magnetite, ko te ilmenite, ko te siderite, ko te pyrite me ētahi atu poke tae. Ko te wehenga aukume te mea nui e whakamahia ana e te rerekētanga aukume i waenga i te kohuke gangue me te kaolin hei tango i ēnei poke tae.
Mō te aukumeiti, te ilmeniti me ētahi atu kohuke aukume kaha, ngā kongakonga rino rānei i konatunatua ki te tukanga tukatuka, he pai ake te whakamahi i te tikanga wehenga aukume hei wehe i te kaolin. Mō ngā kohuke aukume ngoikore, e rua ngā tikanga matua: ko te tuatahi ko te tunu, ka hanga hei kohuke waikura rino aukume kaha, kātahi ka haere tonu te wehenga aukume; Ko tētahi atu huarahi ko te whakamahi i te tikanga wehenga aukume papa aukume teitei hei wehe i te aukume. Nā te mea kāore e hiahiatia he matū hei wehe i te aukume, kāore te taiao e poke, nō reira i roto i te tukanga tukatuka kohuke kore-whakarewa ka whakamahia whānuitia. Kua tino whakatauhia e te tikanga wehenga aukume te raruraru o te whakamahi me te whakamahinga o te kaolin iti-kounga kāore i te uara maina arumoni nā te nui o te rino rino.
Heoi, he uaua ki te whiwhi hua kaolin kounga teitei mā te wehenga aukume anake, ā, me whakamahi i te maimoatanga matū me ētahi atu tukanga hei whakaiti i te nui o te rino i roto i ngā hua kaolin.
3. Te Whakarewatanga
Ko te tikanga whakapūmau e whakamahi ana i ngā rerekētanga ā-tinana me te matū i waenga i ngā kohuke gangue me te kaolin hei rongoā i te konganuku kaolin mata me te nui ake o ngā poke me te whakaiti i te mā, me te tango i ngā poke kei roto te rino, te titanium me te waro, kia tutuki ai te whakamahinga whānui o ngā rauemi kaolin iti-kounga.
He kohuke uku noa te kaolin. He maha ngā poke pēnei i te rino me te titanium e mau ana i roto i ngā matūriki kaolin, nō reira me huri te konganuku mata ki tētahi taumata o te matotoru. Ko te tikanga whakapūmau kaolinite e whakamahia whānuitia ana mō te tikanga whakapūmau matūriki tino pai, te tikanga whakapūmau paparanga wai takirua me te tikanga whakapūmau whakapūmau whiriwhiri, me ētahi atu.
Ka taea e te whakapūngā te whakanui ake i te mā o te kaolin, ko te ngoikoretanga ia he hiahia ki ngā matū hei whakamahi, he nui hoki te utu, ā, ka ngāwari te whakapoke.
4. Maimoatanga matū
Te whakarewa matū: ka taea te whakarewa i ētahi poke o te kaolin mā te waikawa whanariki, te waikawa hauwaiora, te waikawa hauota me ētahi atu kai whakarewa hei tango i ngā poke. Ka taea te whakamahi i tēnei tikanga hei tango i te hematite, te limonite me te siderite mai i te kaolin iti te kounga.
Te whakamaeneene matū: ka taea te whakapūkara i ngā poke o te kaolin hei matū wairewa mā te whakamaeneene, ka taea te horoi me te tango atu hei whakapai ake i te mā o ngā hua kaolin. Heoi, he utu nui te whakamaeneene matū, ā, e whakamahia ana i roto i te kaolin concentrate, me pure anō i muri i te whakakorenga.
Te purenga tunu: ka taea te whakamahi i te rerekētanga o te hanganga matū me te tauhohenga i waenga i ngā poke me te kaolin mō te tunu aukume, te tunu pāmahana teitei, te tunu chlorine rānei hei tango i ngā poke pēnei i te rino, te waro me te whanariki i roto i te kaolin. Ka taea e tēnei tikanga te whakapai ake i te tauhohenga matū o ngā hua kua whakapūkarahia, te whakapai ake i te mā o te kaolin, me te whiwhi hua kaolin kounga teitei. Engari ko te ngoikoretanga o te purenga tunu ko te nui o te pūngao e pau ana, ā, he ngāwari ki te whakapoke i te taiao.
He uaua ki te tiki i ngā kaolin kounga teitei mā te hangarau kotahi. Nō reira, i roto i te mahi hanga, ka tūtohu mātou kia whiriwhiria e koe he kaihanga taputapu tukatuka kohuke whai tohu. Te whakahaere i ngā whakamātautau tukatuka kohuke me te whakamahi i ngā hangarau tukatuka maha hei whakapai ake i te kounga o te Kaolin.
