Enye yezona zimbiwa zaziwayo kwihlabathi ukuba ingoyena mxholo uphezulu wokukhokela yile galena. Kuye kwaqatshelwa ngaphezu kweenkulungwane ezininzi njengoko kusemgangathweni kakuhle kwaye kufumaneka kwiifom ezinomdla kunye ezahlukeneyo. Luhlobo lwembiwa yamaminerali ephambili eyayiyimvelaphi yezinye izimbiwa ezinjenge-cerussite, i-anglesite kunye nelothe. Ezi zimbiwa zisekondari zenziwe galena.
Kule nqaku siza kukubonisa zonke iimpawu, imvelaphi kunye nokusetyenziswa kwe-mineral galena.
Iimpawu eziphambili
Ngaphakathi kolwakhiwo lwe-galena sinokungcola okunje ngesilivere kunye ne-bismuth enokutshintsha iipropathi zembiwa yonke. Ukuba sifumana uhlobo lwe-galena oluqulathe uxinzelelo oluphezulu lwe-bismuth inokuba ne-octahedral cleavage. Xa sifumana isilivere sinokwenza ukuba sibonise amaqhekeza ahlukeneyo.
Kungenxa yeqela le-sulfide kunye inobunzima obuphantsi kwinqanaba leMosh. Ngokuphathelele kumbala wayo, inemibala eqaqambileyo eyenza ukuba ibe nomtsalane kakhulu kwiliso lomntu. Inemibala phakathi kwegrey yentsimbi, eluhlaza okwesibhakabhaka kunye nokuqaqamba. Ngolu luhlu lwemibala ukuchongwa kwayo kuyakhawuleza. Kulabo bangenamava ekwamkelweni kwezimbiwa, kuyinto eqhelekileyo ukudideka, enye izimbiwa ezinje ngomxube. I-Blende yiminerali ephezulu kwi-Iron kwaye ineekristal ezijikeleziweyo. Umahluko ophambili nge-galena kukuba kumnyama, phantse kumnyama. Uxinano nalo lusezantsi kwaye kunzima kakhulu.
Kukho ezinye i-oligistia ezinokuthi zifane ne-galena kodwa zibe ne-red-brown streaking kwaye ayinayo i-cubic. Igali ine-glass shape eyenza ukuba ibonakale okanye i-cubic. Singayifumana iyila i-polyhedron enamacala ama-8 kwaye ide iqhotyoshelwe kwenye nenye. Ukuba uvuthela naluphi na uhlobo lotshintsho kwaye ezinye iikhompawundi zesulfate zongezwa, sinokubona ukuba le minerali iguqulwa ibe yinto esiyaziyo njenge-anglesite kwaye ukuba sidibanisa iicarbonates iba cerussite.
Inokukhutshwa ngaphandle kuthathelwa ingqalelo ukuba umphezulu wayo uthe tyaba kwaye uhlelwe ngokulula njengokukrwela. Oku kuxhomekeke kubuso obupheleleyo obunesiphelo. I-Galena inokwenzeka kwiifom zegranular, ezivuzayo, kunye neefom. Ifomula yayo yemichiza yiPbS.
Imvelaphi yegalena
Igama elithi galena kucingelwa ukuba livela kwigama elithi "galene" elithetha ukukhokela. Eli gama lalisetyenziselwa ukubhekisa kwimali yelothe esinokuyifumana kule minerali. Olunye uphando lubonisa ukuba amaJiphutha nawo asebenzise i-galena ngeenjongo zokuthambisa. Yafakwa emehlweni ukuwakhusela elangeni naseluthulini. Yayisetyenziswa nangokuyifaka emzimbeni ukugxotha izinambuzane.
Imvelaphi yokuxhaphaza i-galena njengesixhobo saqala eCagagagagamakhulu eminyaka eyadlulayo. Imigodi ye-galena yaqala ukuxhaphazeka kwaye kule minyaka idlulileyo iye yaba kukumba okuye ekugqibeleni kwakhokelela ekusebenziseni le minerali kwiindawo ezininzi.
Sinokubona i-galena idipozithi ethi, ngokokuvavanywa kwejoloji, ihlala inxulunyaniswa namatye ngolawulo oluncinci lweasidi okanye amatye egranitic kunye neepegmatitic. Banokufumaneka ecaleni kwemigodi yamatye e-carbonate. Ezi dipozithi ze-galena zifumaneka kwiindawo ezahlukeneyo kwihlabathi liphela kwaye kugxilwe ngokukodwa ekukhutshweni kwale minerali. Ezinye zeendawo kweli hlabathi apho kukhutshwa khona eyona galena zezi: E-Australia, ePeru, eIreland, eCzechoslovakia, eNgilani naseMelika.
E-Spain, sifumana idiphozithi ze-galena eCarolina naseLinares. Zidipozithi apho kufunyanwa ubukhulu obukhulu beGalena. KwiPeninsula yaseIberia sinokufumana kwakhona i-galena eCiudad Real, eMurcia naseLerida.
Ukusetyenziswa kunye nokusetyenziswa kwegalena
Ngoku siza kwazi ukuba kutheni kubalulekile ukukhutshwa kwezimbiwa. AmaJiphutha ayisebenzisa kwiinjongo zokuthambisa kumaxesha amandulo, njengoko besesitshilo ngaphambili. Ukusetyenziswa kwale mihla, kuyabonakala ukuba iikristale ze-galena zamaminerali zazisetyenziselwa ukudibanisa iiradiyo okokuqala. Oku kunjalo kuba basebenze njengezinto zokulungisa imiqondiso ebifakwe zii-eriyali. Kwiminyaka kamva ulungiso lomqondiso we diode lwalungiswa.
Kwii-galenas ezikhutshwe eSpain ezi-argentiferous type Ilothe iyakhutshwa esetyenziselwa ukwenza iityhubhu, amashiti kunye neepellets ezisetyenziselwa ukwenza izikrini zokukhusela kunye nezinye izinto ezinemitha yeathom.
Ukuba sigxila kwindiza yokomoya, kubantu abaninzi i-galena izisa ukuvumelana kunye nokulinganisela ebomini bethu. Iyakwazi ukubonelela ngoncedo kunye nokukwazi ukugcina abantu bajolise kwinyani nakwiinjongo. Kuyatshiwo ukuba kusebenza ukuvula ingqondo kunye nokwandisa izimvo ngelixa ugcina injongo ofuna ukuyilandela. Masingakulibali ukuba ukuhlala ugxile kwinto ofuna ukuyifeza ixesha elide kunzima kunokuba kuvakala. Ke, Abantu abaninzi babhenela kwi-galena necklace or bracelets njengekhubalo.
Kukwathiwa ukuba umntu unxibe i-galena kwaye uhlala enemikhwa emibi, le mikhwa iya kuhlala isemva, ivumela umntu lowo ukuba abenethuba lokutshintsha abe ngcono kunye nokwenza imikhwa enemveliso ebanceda baphumelele.
Into enomdla kukuba kukho abo baphatha isampulu yale minerali ngaphakathi kwiipokotho zebhulukhwe okanye ihempe zabo njengoko inokuba yintsimbi. Ikwahlala ibekwa ngaphakathi ekhaya kunye neendawo zokusebenza ukuze uhlale ukhumbula iinjongo esifuna ukufezekisa.
Njengoko ubona, i-galena yiminerali efunwayo kwaye yaziwa kwihlabathi liphela ngeendlela ezahlukeneyo zokusebenza. Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga negalena.
