Ko te mika tētahi o ngā kohuke matua e hanga ana i te toka, ā, he hanganga paparanga kei roto o te tioata, nō reira he tioata porotītaha hexagonal tōna. Ko te mika te kupu whānui mō te rōpū kohuke mika, ko te nuinga kei roto ko te biotite, te phlogopite, te muscovite, te lepidolite, te sericite, me te lepidolite.
Ngā Āhuatanga o te Kohuke me te Hanganga o te Kohuke
He kohuke aluminosilicate te mika, ā, e toru ngā rōpū iti: te muscovite, te biotite me te lepidolite. Kei roto i te muscovite te muscovite me te konutai mika iti iho i te maha; kei roto i te biotite te phlogopite, te biotite, te manganese biotite; he unahi pai te lepidolite o ngā momo mika e nui ana te lithium oxide; he kohuke uku te sericite me ētahi āhuatanga o te muscovite pai-kikokiko tūturu. I roto i te ahumahi, inā koa i roto i te ahumahi hiko, e whakamahia whānuitia ana te muscovite me te phlogopite. Ko ngā wāhanga matua o te mika ko te silicon, te konumohe, te pāhare pākawa, te konupūmā, te lithium, te wai karaihe me te iti o te rino, te manganese, te titanium, te chromium, te konutai, te konupūmā, me ētahi atu. He tino pai te wehenga o te mika, ā, ka taea te tihore atu. I roto i ēnei, he ngoikore ngā āhuatanga aukume o te biotite me te phlogopite, ā, ko ētahi atu pepa mika ka uru pea ki ngā poke pēnei i te rino me te manganese, ā, he ngoikore hoki ngā āhuatanga aukume. Ko te pakeketanga o te Mohs he 2~3, ko te mātotoru he 2.7~2.9g/cm3, ko ngā kohuke e pā ana ko te pyrite, te tourmaline, te beryl, te feldspar, te quartz, te spinel, te diopside, te tremolite, me ētahi atu, ā, ko ētahi he ngoikore ngā āhuatanga aukume o te rino kōwhai, te tourmaline, te spinel, te diopside, me ētahi atu.
Ngā wāhi tono me ngā tohu hangarau
He pai ngā āhuatanga ā-tinana, ā-matū hoki o Muscovite pērā i te kaha teitei o te dielectric, te ātete teitei, te iti o te ngaronga dielectric, te ātete pewa, te ātete korona, te kakano mārō, te kaha miihini teitei, te ātete pāmahana teitei, te ātete waikawa me te kawakore, nō reira he whānuitia te whakamahinga i roto i te ahumahi. He whānuitia ngā whakamahinga; he iti ake te kounga o ngā āhuatanga matua o te phlogopite mika i te muscovite mika, engari he nui te ātete wera, ā, he rauemi pai hei ārai wera; ko te kongakonga mika e pā ana ki te kupu whānui mō te mika pai e keria ana me ngā toenga e puta mai ana i te tukatuka me te papa. ; Ko te Lepidolite, e mōhiotia ana ko te phosphomica, he rauemi mata kohuke mō te tango lithium, ā, he whānuitia te whakamahinga o te sericite i roto i te rapa, te kirihou, te whakarewa, te whakapaipai, me ētahi atu.
Hangarau Tukatuka
Te painga me te purenga
He rerekē ngā tikanga whakapai me te purenga o te mika i runga i tōna āhua me tōna momo. Ko te mika maramara te tikanga he wehewehe ā-ringa, he whakapai waku, he whakapai āhua, me ētahi atu; ko te mika kuru ka taea te wehe me te whakamānu i te hau, ko te biotite me te phlogopite ka taea te wehe aukume kaha, ā, he ngoikore ngā āhuatanga aukume o te muscovite, te lepidolite me te sericite. Ka taea hoki te tango i ngā poke mā te wehenga aukume kaha.
01 Te kōwhiri (te tohu) i te kōwhiringa
I te mata o te keri, i te puranga konganuku rānei i te poka, ka tīpakohia te mika kua wehea mai i te monomer, ā, he pai mō ngā mika maramara nui.
02 Te whakapai ake i te waku
E ai ki te rerekētanga i waenga i te tauwehenga waku pahekeheke o te tioata mika pakaka me te tauwehenga waku hurihuri o te gangue porowhita, ka wehea te tioata mika me te gangue. Ko tētahi o ngā taputapu e whakamahia ana ko te mīhini wehewehe pereti whakarara.
03 Te whakapai ake i te āhua
E ai ki ngā āhua rerekē o ngā tioata mika me te gangue, he rerekē te kaha ki te haere mā roto i te āputa tatari, i te kōhao tatari rānei i te wā e tatari ana, ā, ka wehea te mika me te gangue.
04 Kōwhiringa hau
I muri i te kuru o te onepu me te kirikiri, ka rite te āhua o te mika ki ngā kirikiri maramara, ko ngā kohuke gangue ia he rite ki ngā matūriki nunui. Whai muri i te whakarōpūtanga maha-taumata, ka whakamahia he taputapu motuhake mō te wehewehe hau i runga i te rerekētanga o te tere whakatārewatanga o te hau.
05 Te Whakaterenga
I tēnei wā, e rua ngā tukanga whakapūmau: ko tētahi ko te whakapūmau i te mika me ngā kaikohi amine i roto i te reo waikawa; ko tētahi ko te whakapūmau me ngā kaikohi anionic i roto i te reo kawakore, me tango te paru i mua i te tīpakonga, ā, me tīpakohia hoki i ngā wā maha.
06 Wehenga aukume
He ngoikore ngā āhuatanga aukume o te biotite me te phlogopite, ā, ka taea te whiriwhiri mā te tikanga aukume kaha; he maha ngā wā ka honoa ngā poke o te waikura rino me te silicate rino ki te muscovite, te sericite me te lepidolite, ka taea hoki te tango mā te wehenga aukume kaha. Ko ngā taputapu wehenga aukume ko ngā roera aukume kaha maroke me te mākū, ngā wehewehe aukume pereti me ngā wehewehe aukume porowhita poutū teitei.
Hutia atu
Ko te tihore i te mika mata ki roto i ngā rau mika o ngā momo āhuatanga rerekē ka kiia ko te tihore i te mika. I tēnei wā, e toru ngā tikanga tihore, arā, he ā-ringa, he ā-mīhini, he ā-tinana, he ā-matū hoki, e whakamahia ana mō te tukatuka pērā i ngā rau matotoru, ngā rau angiangi, me te mika ngongo.
Te huri pai me te huri tino pai
E rua ngā momo hanga o te huri pai me te huri tino pai o te mika, arā, te tikanga maroke me te tikanga mākū. Haunga ngā taputapu kuru me te huri, me whai taputapu anō hoki te tikanga maroke pērā i te tātari me te whakarōpūtanga hau. He maha ngā taputapu huri mākū e whakamahia ana i roto i te hanga mākū, ā, ko te hangarau huri mākū te ia o te whanaketanga matua o te hanga paura mika pai.
Te whakarerekētanga o te mata
Ka taea te wehewehe i te whakarerekētanga mata o te paura mika ki ngā tukanga e rua: te whakarerekētanga mata waro me te whakarerekētanga paninga mata kore-waro. Ka taea e te hua mika whakarerekētia te whakapai ake i te kaha ā-pūkaha o te rauemi, te whakaiti i te tere whakahekenga o te whakakōhua, te pai o te pānga tirohanga whatu me te whakapai ake i te uara tono, me ētahi atu.
