Ko te feldspar tētahi o ngā kohuke hanga toka tino nui i roto i te kirinuku o te whenua. He whānuitia te whakamahinga o te feldspar whai pāhare pākawa, te konutai rānei, i roto i ngā uku, te enamel, te karāhe, ngā mea whakakoi, me ētahi atu rāngai ahumahi. Nā te nui o te pāhare pākawa, ā, he rauemi pāhare pākawa kore-wairewa hoki, ka taea te whakamahi i te feldspar pāhare pākawa ā muri ake nei hei hanga tongi pāhare pākawa, ka waiho hei rauemi kohuke rautaki nui. Ka taea e te feldspar kei roto ngā huānga onge pērā i te rubidium me te cesium te whakamahi hei puna kohuke mō te tango i ēnei huānga. Ka taea te whakamahi i te feldspar tae ataahua hei kōhatu whakapaipai me ngā kohatu utu nui.
Haunga te mea he rauemi mata mō te umanga karāhe (e 50-60% o te katoa o te whakamahinga), ka whakamahia hoki te feldspar i roto i te umanga uku (30%), ko te toenga ka whakamahia i roto i ngā matū, ngā mea whakakoi, te muka karāhe, ngā irahiko whakarewa, me ētahi atu ahumahi.
Rerenga Karāhe
Ko te Feldspar tētahi o ngā wāhanga matua o ngā ranunga karāhe. Nā te nui o te Al₂O₃ me te iti o te rino, ka rewa te feldspar i te pāmahana iti iho, ā, he whānui te awhe rewa. Ko te nuinga o te whakamahinga hei whakanui ake i te nui o te alumina i roto i ngā ranunga karāhe, hei whakaiti i te pāmahana rewa, hei whakanui ake hoki i te nui o te kawakore, kia whakaitihia ai te nui o te kawakore e whakamahia ana. Hei tāpiri, ka rewa mārire te feldspar ki roto i te karāhe, hei ārai i te hanganga o ngā tioata ka kino pea te hua. Ka āwhina hoki te feldspar ki te whakahaere i te matotoru o te karāhe. I te nuinga o te wā, ka whakamahia te feldspar pāhare pāporo, te konutai rānei i roto i ngā ranunga karāhe maha.
Ngā Kai o te Tinana Uku
I mua i te tahunga, ka mahi te feldspar hei rauemi mata angiangi, ka whakaiti i te mimiti me te whakarerekētanga o te tinana, ka whakapai ake i te mahi whakamaroke, ka whakapoto hoki i te wā whakamaroke. I te wā e tahuna ana, ka mahi te feldspar hei rerenga hei whakaheke i te pāmahana tahunga, hei whakatairanga i te rewa o te quartz me te kaolin, ā, hei whakahaere i te hanganga o te mullite i roto i te wāhanga wai. Ka whakakīia ngā pata tioata mullite i roto i te tinana e te karāhe feldspar i hangaia i te wā e rewa ana, ka whakakīia, ka whakaitihia te porosity, ā, ka whakanuia tōna kaha miihini me ōna āhuatanga dielectric. Hei tāpiri, ka whakanuia e te hanganga o te karāhe feldspar te mārama o te tinana. Ka rerekē te nui o te feldspar i tāpirihia ki ngā tinana uku i runga i ngā rauemi mata me ngā whakaritenga hua.
Kirīmi Uku
Ko te nuinga o te wā, ko te feldspar, te quartz, me te uku te mea hanga o te paninga uku, ā, ko te nui o te feldspar kei waenganui i te 10-35%. I roto i te umanga uku (tinana me te paninga), ko te pāhare pākawa te mea matua e whakamahia ana.
Ngā Āhuatanga Ā-tinana me te Matū
He kohuke whānui te feldspar i runga i te whenua, he nui te pāhare pākawa e mōhiotia ana ko te pāhare pākawa feldspar, e tohuhia ana i roto i te matū ko te KAlSi₃O₈. Ko te orthoclase, te microcline, me te sanidine he kohuke pāhare pākawa feldspar katoa. He pai te pumau matū o ēnei feldspar, ā, he ātete ki te pirau waikawa. Ko te pakeke o ēnei ko te 5.5-6.5, ko te taumaha motuhake o te 2.55-2.75 t/m³, ā, ko te ira rewa o te 1185-1490°C. Ko ngā kohuke e pā ana ko te quartz, te muscovite, te biotite, te beryl, te garnet, me te iti o te magnetite, te columbite, me te tantalite.
Te Whakarōpūtanga o ngā Putunga Feldspar
E rua ngā momo o ngā putunga feldspar i runga i te pūtake:
1. **Gneiss, Migmatitic Gneiss rānei**: Ka kitea ētahi uaua i roto i ngā toka karāneti, i ngā toka taketake rānei, i roto rānei i ō rātou rohe whakapā. Ko te nuinga o te wā ka kukū te konganuku ki te rohe poraka feldspar o ngā pegmatites, ngā pegmatites feldspar kua wehea kētia rānei.
2. **Ngā Putunga Feldspar Momo Toka Āwhata**: Ka puta ēnei putunga i roto i ngā toka āwhata waikawa, waenga, me te kawakore. Ko ngā mea e kitea ana i roto i ngā toka kawakore te mea nui, pērā i te nepheline syenite, ā, whai muri ko te karāneti, te karāneti albite, te karāneti orthoclase, me ngā putunga karāneti orthoclase quartz.
I runga i te tukanga whakakoi o te feldspar, ka wehea ngā putunga feldspar ki te momo toka mura, te momo pegmatite, te momo karāneti kua pakaru te rangi, me te momo toka parataiao, ko ngā momo pegmatite me te toka mura ngā mea matua.
Ngā Tikanga Wehewehe
- **Whakarōpū ā-Ringa**: I runga i ngā rerekētanga kitea o te āhua me te tae mai i ētahi atu kohuke gangue, ka whakamahia te whakarōpū ā-ringa.
- **Wehenga Aukume**: I muri i te kuru me te huri, ka whakamahia ngā taputapu wehenga aukume pēnei i ngā wehewehe aukume pereti, ngā wehewehe aukume porowhita teitei LHGC, me ngā wehewehe aukume paru aukume HTDZ hei tango i te rino aukume ngoikore, te titanium, me ētahi atu kohuke poke hei purenga.
- **Te Whakarewa**: Ka whakamahia te waikawa HF i raro i ngā āhuatanga waikawa, me ngā kationa amine hei kaikohi mō te wehewehe i te feldspar mai i te quartz.
Mō ētahi atu kōrero mō ngā wehewehe aukume Huate me pēhea e taea ai e rātou te āwhina i te purenga me te wehenga o te feldspar me ētahi atu kohuke, tirohia tā mātou paetukutuku. Kei te Huate Magnetic Separator ngā otinga wehenga aukume matatau kua whakaritea mō ō hiahia ahumahi.
