Tirohanga whānui mō Spodumene
Ko te tātai ngota o te spodumene ko LiAlSi2O6, ko te mātotoru he 3.03~3.22 g/cm3, ko te pakeke he 6.5-7, kāore i te aukume, he kanapa karāhe, ko te taumata ariā o Li2O he 8.10%, ā, he poupou, he kirikiri, he rite rānei ki te pereti te spodumene. He pūnaha tioata monoclinic, ko ōna tae noa he papura, he hina-kakariki, he kōwhai me te hina-mā. He konganuku māmā te lithium me ngā āhuatanga ā-tinana me te matū motuhake. I whakamahia nuitia i roto i te umanga hōia i ngā rā o mua, ā, i kiia he matū rautaki. I tēnei wā, neke atu i te 100 ngā momo lithium me ōna hua. Ko te lithium te nuinga e whakamahia ana i roto i te hanga pākahiko lithium kaha-teitei, ngā tāpiringa i roto i te electrolysis o te konumohe, me ngā hinu whakahinuhinu ātete-pāmahana iti. Hei tāpiri, kei te whānui haere te tono i roto i ngā mara o te uku karāhe, ngā taputapu hiko, te rongoā me te umanga matū.
Hei kohuke lithium totoka e nui ana te lithium, ā, he mea tino pai mō te hanga ahumahi o ngā tote lithium, ko te spodumene e horahia ana i Ahitereiria, Kanata, Zimbabwe, Zaire, Brazil me Haina. He nui ngā rauemi lithium i ngā maina spodumene i Xinjiang Keketuohai, Ganzi me Aba i Sichuan, me ngā maina lepidolite i Yichun, Jiangxi. Koinei ngā wāhi matua mō te keri i ngā kohuke lithium totoka i Haina i tēnei wā.
Te taumata kukū Spodumene
Ka wehea ngā matūriki Spodumene ki ngā whakamahinga me ngā taumata rerekē. Kei te ripanga i raro nei te paerewa mō ngā taumata o te putanga matūriki. Kei roto i ngā taumata putanga matūriki ngā wāhanga e toru e whai ake nei: te matūriki lithium rino-iti, te matūriki lithium mō ngā uku me te matūriki lithium mō te ahumahi matū.
Tikanga whakapai ake i te konganuku Spodumene
He maha ngā āhuatanga e pāngia ana e te wehenga o te spodumene, pērā i: te hononga tahi o ngā kohuke, te momo hanganga o te konganuku, me ētahi atu, e hiahia ana ki ngā tukanga whakapainga rerekē.
Te Whakaterenga：
He uaua te wehewehe i te spodumene mai i ngā kohuke silicate he rite te mahi whakapūngā i roto i ngā tikanga whakapūngā spodumene i te kāinga me tāwāhi. Ka taea te wehewehe i te tukanga whakapūngā spodumene ki te tukanga whakapūngā whakamuri me te tukanga whakapūngā pai. Ka taea te wehewehe i ngā kohuke matua kei roto te lithium mā te whakapūngā, inā koa mō ngā spodumene he iti te kounga, he pai te hanganga, he uaua te hanganga, he mea tino nui te whakapūngā.
Wehenga aukume：
Ko te wehenga aukume he mea noa hei tango i ngā poke rino kei roto i ngā kukū lithium, hei wehe rānei i te rino-lepidolite aukume ngoikore. I roto i te mahi whakaputa, ko te kukū spodumene i whiwhihia mā te tikanga whakatārewatanga he nui ake ngā poke rino kei roto. Hei whakaiti i te nui o ngā poke rino, ka taea te whakamahi i te wehenga aukume mō te maimoatanga. Ko ngā taputapu wehenga aukume he wehenga aukume momo-pahu aukume tuturu, he wehenga aukume momo-pereti aukume kaha momo-māku, me te wehenga aukume porowhita-teitei porowhita poutū. Ko ngā toenga spodumene he mea hanga nui mai i te feldspar, ā, ka taea hoki te whakamahi i ngā wehenga aukume porowhita-teitei porowhita poutū me ngā wehenga aukume paru aukume hei tango i ngā poke hei whiwhi hua feldspar e tutuki ai ngā whakaritenga mō ngā rauemi mata uku.
Tikanga Waenga Matotoru：
I raro i ngā āhuatanga pāmahana noa, he paku nui ake te mātotoru o te spodumene i roto i te konganuku spodumene i ērā o ngā kohuke gangue pērā i te quartz me te feldspar, arā, tata ki te 3.15 g/cm3. I te nuinga o te wā, ka whakarōpūhia te konganuku spodumene mā te whakamahi i te wai taumaha me te mātotoru i waenga i te mātotoru o te spodumene, te quartz me te feldspar, pērā i te tribromomethane me te tetrabromoethane. I roto i a rātou, he nui ake te mātotoru o te spodumene i ērā o ēnei wai taumaha, nō reira ka totohu ki raro, ka wehea mai i ngā kohuke gangue pērā i te feldspar me te quartz.
Tikanga painga whakakotahi:
I tēnei wā, he uaua ki te whiwhi i ngā kukū konukōrete whai tohu mō ngā kohuke konukōrete "kino, pai, me ngā momo rerekē" mā te tikanga kotahi o te whakapai. Me whakamahi te tikanga whakapai whakakotahi. Ko ngā tukanga matua ko: te tukanga whakakotahi wehenga pūngao-taimaha-wehenga aukume, te tukanga whakakotahi wehenga pūngao-aukume, te tukanga whakakotahi maimoatanga pūngao-matū, me ētahi atu.
Ngā tauira o te whakamahi i te spodumene:
Ko te kohuke matua whai hua o te konganuku spodumene i kawemai mai i Ahitereiria ko te spodumene, me te ihirangi Li2O o te 1.42%, he konganuku lithium taumata-waenga. He maha atu ngā kohuke kei roto i te konganuku. Ko ngā kohuke gangue ko te nuinga o te feldspar, te quartz, te muscovite, me te hematite mine me ētahi atu.
Ka whakarōpūtia te Spodumene mā te huri, ā, ka whakahaeretia te rahi o te matūriki kua tīpakohia ki te -200 mata 60-70%. He nui te paru tuatahi pai-kikokore i roto i te konganuku taketake, ā, ko te chlorite me ētahi atu kohuke e ngāwari ana te paru i te wā e kuruhia ana, e huri ana, he maha ngā wā ka tino whakararuraru i te rere noa o te konganuku. Ka tangohia te paru pai mā te tango i te paru. Mā te tukanga whakakotahi o te wehenga aukume me te rere, ka whiwhihia ngā hua e rua, te kukū spodumene me te kukū feldspar, ka taea te whakamahi hei rauemi mata uku.
