Elinye lamaminerali aziwa kakhulu emhlabeni ngokuba yilowo onokuqukethwe okuhola phambili kakhulu yi galena. Kuye kwaqashelwa ngaphezu kwamakhulu amaningi eminyaka njengoba kusesimweni sokukhanyiswa kahle futhi kungatholakala ngezindlela ezithokozisayo nezinhlobonhlobo. Luhlobo lwamaminerali ayinhloko okwakuyimvelaphi yamanye amaminerali afana ne-cerussite, i-anglesite nomthofu. Lawa amaminerali wesibili akhiwa kusuka egalena.
Kule ndatshana sizokukhombisa zonke izici, imvelaphi nokusetshenziswa kwe-mineral galena.
Izici eziyinhloko
Ngaphakathi kwesakhiwo se-galena sinokungcola okuthile okufana nesiliva ne-bismuth okungashintsha izakhiwo zawo wonke amaminerali. Uma sithola uhlobo lwe-galena oluqukethe ukuminyana okuphezulu kwe-bismuth ingahle ibe ne-octahedral cleavage. Lapho sithola isiliva singayenza futhi ibonise izingcezu ezahlukahlukene ezigoqiwe.
Kungeqembu lama-sulfide futhi inobulukhuni obuphansi esikalini sikaMosh. Ngokuqondene nombala wayo, inemibala ehehayo eyenza ukuthi ihehe ngokweqile iso lomuntu. Inemibala phakathi kwempunga yensimbi, eluhlaza okwesibhakabhaka okukhulu nokugqamile. Ngokuba nalolu chungechunge lwemibala ukuhlonza kwayo kushesha impela. Kulabo abangenakho okuhlangenwe nakho ekwamukelweni kwamaminerali, kuyinto ejwayelekile ukudideka, enye imbiwa efana ne-blende. I-Blende ingumbiwa phansi ku-Iron futhi inamakristalu ayindilinga. Umehluko omkhulu ne-galena ukuthi kumnyama, kucishe kube mnyama. Ubuningi nabo buphansi futhi bunzima kakhulu.
Kukhona amanye ama-oligistia angafana ne-galena kodwa abe ne-streaking ebomvu-nsundu futhi ayiwona ama-cubic. I-galley inesimo sengilazi esenza ibukeke noma i-cubic ngokuvamile. Futhi singakuthola kwakheka i-polyhedron enamacala ayisishiyagalombili futhi sinamathele komunye nomunye. Uma ushaya noma yiluphi uhlobo lokuguqulwa futhi kunezelwa ezinye izinhlanganisela ze-sulfate, siyabona ukuthi le minerali iguqulwa ibe yilokho esikwaziyo njenge-anglesite futhi uma sifaka ama-carbonates iba yi-cerussite.
Ine-exfoliation icabangela ukuthi ingaphezulu layo liyisicaba futhi libhekwa njengokulula ukuliklwebha. Lokhu kuncike ebusweni obuphelele lapho i-terminal inakho. IGalena ingenzeka ngamafomu ayimbudumbudu, avuzayo, futhi acwenga kakhulu. Ifomula yayo yamakhemikhali yi-PbS.
Umsuka wegalena
Igama elithi galena kucatshangwa ukuthi livela egameni elithi "galene" elisho ukuhola. Leli gama lalisetshenziselwa ukubhekisa kumanani omthofu esingawathola kule mineral. Olunye ucwaningo lukhombisa ukuthi abaseGibhithe nabo basebenzise i-galena ngezinhloso zokugcoba. Yasetshenziswa emehlweni ukusiza ukuwavikela elangeni nasothulini. Yayisetshenziswa futhi nokuyigcoba emzimbeni ukuxosha izinambuzane.
Imvelaphi yokuxhashazwa kwe-galena njengesisetshenziswa yaqala eCartaggena emakhulwini eminyaka adlule. Izimayini ze-galena zaqala ukuxhashazwa futhi eminyakeni edlule sekuyizimbiwa ezigcine zisebenzisile ukusebenzisa le minerali ezindaweni eziningi.
Singabona amadiphozi e-galena okuthi, ngokuya ngokuhlolwa kwe-geological, kuvame ukuhlotshaniswa namatshe anombuso we-asidi omncane noma amatshe e-granitic kanye ne-pegmatitic. Zitholakala futhi eduze kwemayini yedwala le-carbonate. Lezi zimali ze-galena zitholakala ezindaweni ezahlukahlukene emhlabeni jikelele futhi ukunakekelwa okukhethekile kukhokhelwe ekukhishweni kwalesi simbiwa. Ezinye zezindawo kulo mhlaba lapho kukhishwa khona igalena kakhulu yilezi: I-Australia, iPeru, i-Ireland, iCzechoslovakia, iNgilandi kanye ne-United States.
ESpain, sithola imali egalena eCarolina naseLinares. Yizibambiso lapho kutholakala khona ubukhulu obukhulu beGalena. ENhlonhlweni Yase-Iberia singathola futhi i-galena eCiudad Real, eMurcia naseLérida.
Ukusetshenziswa nokusetshenziswa kwe-galena
Manje sesizokwazi isizathu sokubaluleka kokukhishwa kwale mineral. AbaseGibhithe babeyisebenzisela izinjongo zezimonyo ezikhathini zasendulo, njengoba sishilo ngaphambili. Ekusetshenzisweni kwanamuhla, kungabonakala ukuthi amakristalu amaminerali e-galena asetshenziselwe ukuhlanganisa imisakazo okokuqala ngqa. Lokhu kunjalo ngoba basebenze njengento yokulungisa amasiginali athunjwa yizimpondo. Eminyakeni yamuva into yokulungiswa kwesiginali ye-diode yaguqulwa.
Of the galenas ukuthi akhishwe eSpain ukuthi kukhona uhlobo argentiferous Kukhishwa umthofu osetshenziselwa ukwenza amashubhu, amashidi namapellets asetshenziselwa ukwenza izikrini zokuvikela nezinye izinto ezikhipha imisebe.
Uma futhi sigxila endizeni engokomoya, kubantu abaningi i-galena iletha ukuvumelana nokulinganisela ezimpilweni zethu. Iyakwazi ukuhlinzeka ngosizo futhi ikwazi ukugcina abantu begxile kokungokoqobo nasezinhlosweni. Kuthiwa kusebenza ukuvula ingqondo nokwandisa imibono ngenkathi kugcinwa umgomo ofuna ukuwulandela. Masingakhohlwa ukuthi ukuhlala ugxile entweni ofuna ukuyizuza isikhathi eside kunzima kakhulu kunokuba kuzwakala. Ngakho-ke, Abantu abaningi baphendukela emigexo noma amasongo e-galena njengentelezi.
Kuyaye kuthiwe uma umuntu egqoke i-galena futhi imvamisa enemikhuba emibi, le mikhuba izohlala ingemuva, ivumele lowo muntu ukuba abe nethuba lokushintshela kokungcono futhi adale imikhuba ekhiqizayo ebasiza ukuthi baphumelele.
Into enelukuluku ukuthi kukhona labo abaphatha isampula laleli ezimbiwa ngaphakathi kwamaphakethe amabhulukwe noma amahembe njengoba nje kungaba yintelezi. Ibuye ibekwe ngaphakathi ekhaya nasezindaweni zokusebenza ukuze uhlale ukhumbula izinhloso esifuna ukuzifeza.
Njengoba ukwazi ukubona, i-galena iyiminerali efunwa kakhulu eyaziwa emhlabeni wonke enokusetshenziswa okuhlukahlukene okusebenzayo. Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngegalena.
