Monazite
·Monazite, inozivikanwawo se phosphocerium lanthanide ore, inowanikwa mugranite uye granite pegmatite; Rare metal carbonate rock; Mu quartzite uye quartzite; MuYunxia syenite, feldspar aegirite, uye alkaline syenite pegmatite; Alpine type tsinga; Mune yakasanganiswa dombo uye weathered crust uye jecha ore. Nekuda kwekuti iyo huru sosi yemonazite ine kukosha kwemigodhi yehupfumi ndeye alluvial kana mahombekombe ejecha dhipoziti, inonyanya kugoverwa kumahombekombe eAustralia, Brazil, neIndia. Pamusoro pezvo, Sri Lanka, Madagascar, South Africa, Malaysia, China, Thailand, South Korea, North Korea nedzimwe nzvimbo zvese zvine zvinorema placer deposits yemonazite, inonyanya kushandiswa kuburitsa zvisingawanzo zvinhu zvepasi. Mumakore achangopfuura, kugadzirwa kwemonazite kwakaratidza kuderera, zvakanyanya nekuda kweiyo radioactive thorium element mune yayo ore, inokuvadza kune zvakatipoteredza.
Kuumbwa kwemakemikari uye zvivakwa: (Ce, La, Y, Th) [PO4]. Kuumbwa kunosiyana zvikuru. Zviri mukati mezvisingawanzo pasi oxidesmumineral kuumbwa kunogona kusvika 50-68%. Iyo isomorphic musanganiswa inosanganisira Y, Th, Ca, [SiO4], uye [SO4].
Monazite inonyungudika muH3PO4, HClO4, uye H2SO4.
Crystal chimiro uye morphology: monoclinic crystal system, rhombic columnar crystal mhando. Iyo kristaro inoumba ndiro-yakafanana chimiro, uye kristaro pamusoro kazhinji ine mitsetse kana columnar, conical, kana granular maumbirwo.
·Zvimiro zvemuviri: Yero yebrown, yebrown, tsvuku, uye dzimwe nguva yegirini muruvara. Semi transparent to transparent. Mitsetse ichena kana kuti yakatsvuka yero. Iine girazi rakasimba rinopenya. Kuoma 5.0-5.5. Embrittlement. Iyo chaiyo giravhiti inotangira kubva 4.9 kusvika 5.5. Pakati nepakati isina simba remagetsi emagetsi. Kubudisa chiedza chegirini pasi peX-rays. Haibudisi chiedza pasi pemaranzi e-cathode.
Yttriumphosphate ore
·Phosphorusyttriumore inonyanya kugadzirwa mugranite, granite pegmatite, uye zvakare mune alkaline granite uye zvine chekuita nemamineral deposits. Inogadzirwawo mune placers. Kushandiswa: Inoshandiswa seminerari mbishi zvinhu zvekucherarare pasizvinhu kana zvakafumiswa muhuwandu hukuru.
Kuumbwa kwemakemikari uye zvivakwa: Y [PO4]. Kuumbwa kunosanganisiraY2O361.4% uye P2O5 38.6%. Pane musanganiswa weyttriumbokarare pasizvinhu, kunyanyaytterbium, erbium, dysprosium,uyegadolinium. Zvinhu zvakadaizirconium, uranium, uye thorium zvichiri kutsivayttrium, aposiliconzvakare inotsiva phosphorus. Kazhinji kutaura, zviri mukati uranium mu phosphorusyttriumore yakakura kupfuura iyo yethorium. Izvo zvemakemikari zvimiro zveyttriumphosphate ore dzakagadzikana. Crystal chimiro uye morphology: tetragonal crystal system, yakaoma tetragonal biconical crystal mhando, mune granular uye block fomu.
Zvimiro zvemuviri: yero, dzvuku dzvuku, dzimwe nguva yero yegirini, zvakare yebrown kana yebrown. Mitsetse yacho ine ruvara rwakajeka. Girazi rinopenya, girizi inopenya. Kuoma 4-5, chaiyo giravhiti 4.4-5.1, ine isina kusimba polychromism uye radioactivity.
Lanthanum vanadium epidote
Chikwata chakabatana chekutsvagisa kubva kuYamaguchi University, Ehime University, uye University of Tokyo muJapan yakaburitsa chirevo ichiti vakawana mhando nyowani yemaminerari ine isingawanzo pasi muSanchong Prefecture.Rare pasizvinhu zvinotora basa rakakosha mukushandura maindasitiri echinyakare uye kugadzira minda yepamusoro-soro. Iyo mineral nyowani yakawanikwa mumakomo eIse City, Sanchong Prefecture muna Kubvumbi 2011, uye imhando yakakosha yebrown epidote ine.rare pasi lanthanumuye isingawanzo simbi vanadium. Musi waKurume 1, 2013, iyi mineral yakaonekwa sechicherwa chitsva neInternational Association of Mineralogy uye yakanzi "lanthanum vanadium limonite".
