Imwe yemaminerari anozivikanwa pasi rose yekuve iyo ine yepamusoro yekutungamira yezvinyorwa ndeye galena. Yakave ichizivikanwa kwemazana emakore mazhinji sezvazviri mune yakanyatsorongedzwa mamiriro uye inogona kuwanikwa mune anonakidza uye akasiyana mafomu. Iyo mhando yemaminerari epakutanga yaive mavambo ezvimwe zvicherwa senge cerussite, anglesite uye lead. Iyi yechipiri maminera akaumbwa kubva galena.
Muchikamu chino tiri kuzokuratidza hunhu hwese, mavambo uye mashandisiro eiyo mineral galena.
Mhando huru
Mukati mechimiro che galena isu tine zvakasviba senge sirivheri uye bismuth inogona kushandura zvivakwa zvemaminerari ese. Kana isu tikawana mhando yegalena iyo ine yakanyanya kuwanda kwebismuth inogona kunge iine octahedral cleavage. Kana tawana sirivheri tinogonawo kuti iratidze zvidimbu zvakasiyana zvakapetana.
Icho chiri cheboka re sulfide uye ine hushoma hwakaderera pamwero weMosh. Kana iri ruvara rwayo, ine mavara anokatyamadza ayo anoita kuti riwedzere kukwezva kuziso remunhu. Iyo ine mimvuri pakati pesimbi grey, yakasimba bhuruu uye inopenya. Nekuva neiyi nhevedzano yemavara kuzivikanwa kwayo kuri kukurumidza. Kune avo vasina ruzivo mukucherechedzwa kwemaminerari, zvakajairika kuvhiringidzika, imwe maminera senge musanganiswa. Blende ndeyemaminerari yakakwira mu Iron uye yakatenderedza makristasi. Musiyano mukuru negalena ndeyekuti yakasviba, ingangoita nhema. Kuwanda kwacho kwakadzikawo uye kwakanyanya kuoma.
Kune mamwe oligistia ayo anogona zvakare kunge akafanana galena asi aine mutsvuku-mutsvuku streaking uye asiri cubic. Iyo gali ine girazi dhizaini inoita kuti iratidzike kana kazhinji cubic. Isu tinogona zvakare kuiwana ichiumba iyo 8-mativi polyhedron uye kunyange yakasungirirwa kune imwe neimwe. Kana iwe ukaridza chero rudzi rwechinjo uye mamwe masulphate makomputa akawedzerwa, tinogona kuona kuti ichi chicherwa chinoshandurwa kuita zvatinoziva seanglesite uye kana tikabatanidza carbonates inova cerussite.
Iine exfoliation ichifunga kuti pamusoro payo pakapfava uye inorondedzerwa senge iri nyore kukwenya. Izvi zvinoenderana nezviso zvese zvine iyo terminal. Galena inogona kuitika mune mafruza, anodonhedza, uye exfoliating mafomu. Yayo yemakemikari fomula ndeyePbS.
Kwakatangira galena
Izwi rekuti galena rinofungidzirwa kuti rinobva pashoko rinoti "galene" iro rinoreva kutungamira. Izwi iri rakashandiswa kureva huwandu hwemutobvu hwatinogona kuwana mune ino zvicherwa. Kumwe kutsvagurudza kunoratidza kuti maEjipitori akashandisawo galena kuzvigadzirisa. Yakaiswa kumeso kubatsira kuvadzivirira kubva kuzuva uye guruva. Chaishandiswawo nekuchiisa mumuviri kudzinga zvipembenene.
Kwakatangira kushandiswa kwe galena sosi kwakatanga muCagagena mazana emakore apfuura. Iyo yemigodhi ye galena yakatanga kushandiswa uye pamusoro pemakore aya ave ekuchera ayo akazopedzisira ashandisa kushandisa ichi chicherwa munzvimbo dzakawanda.
Tinogona kuona galena inoisa iyo, zvinoenderana nekuongororwa kwejogiki, inowanzo kuve yakabatana nematombo aine mashoma asidi hutongi kana matombo egranitic uye pegmatitic. Inogona zvakare kuwanikwa padhuze neacabhonate matombo emigodhi. Aya ma galena deposits anowanikwa munzvimbo dzakasiyana siyana pasirese uye kukoshesa kwakabhadharwa kuburitsa ichi chicherwa. Dzimwe dzenzvimbo dzenyika ino uko kwakanyanya kuburitswa galena ndeiyi: Australia, Peru, Ireland, Czechoslovakia, England neUnited States.
MuSpain, tinowana galena anoisa muCarolina neLinares. Iwo madhipatimendi panowanikwa hukuru hwakakura hweGalena. MuIberian Peninsula tinogona zvakare kuwana galena muCiudad Real, Murcia neLerida.
Zvishandiso uye mashandisiro egalena
Iye zvino tave kuzoziva chikonzero chekukosha kwekuburitsa chicherwa ichi. VaIjipita vakaishandisa yezvizoro munguva dzekare, sezvatakambotaura. Mukushandisa kwazvino uno, zvinogona kuoneka kuti galena zvicherwa zvemakristasi zvakashandiswa kutanga kuunganidza mawairesi. Izvi ndezve izvo sezvo ivo vakaita sechinhu chekugadzirisa pazviratidzo zvakatorwa nemaantena. Makore apfuura makore diode chiratidzo chekugadzirisa chinhu chakashandurwa.
Ye ma galenas ayo anotorwa muSpain ayo ari esirivha-senge rudzi lead inoburitswa iyo inoshandiswa kugadzira machubhu, machira nemapellets ayo anoshandiswa kugadzira masikirini ekudzivirira uye zvimwe zvinhu zvine mwaranzi.
Kana isu zvakare tichitarisa kune yemweya ndege, kune vanhu vazhinji iyo galena inounza kuwirirana uye kuenzanisa muhupenyu hwedu. Iyo inokwanisa kupa rubatsiro uye kugona kuchengetedza vanhu vakatarisana nezvazviri uye zvinangwa. Izvo zvinonzi zvinoshanda kuvhura pfungwa uye nekuwedzera mazano iwe uchichengetedza iyo chinangwa chaunoda kuteedzera. Ngatisakanganwe kuti kuramba wakanangisa pane chimwe chinhu chaunoda kuzadzikisa kwenguva yakareba zvakaoma kupfuura zvinonzwika. Saka, Vanhu vazhinji vanotendeukira kugalena mitsipa kana zvishongo sechishongo.
Zvinonzi zvakare kana munhu akapfeka galena uye kazhinji aine maitiro asina kunaka, tsika idzi dzinoramba dziri kumashure, zvichitendera kuti munhu ave nemukana wekushandukira kuita zvirinani uye nekugadzira hunhu hunovabatsira hunobudirira.
Chinhu chinodakadza ndechekuti kune avo vanotakura sampuro yeichi chicherwa mukati mehomwe dzemabhurugwa avo kana mahembe sekungove chirahwe. Iyo zvakare inowanzoiswa mukati memba uye nenzvimbo dzebasa kuti tigare tichifunga mundangariro zvinangwa zvatinoda kuzadzisa.
Sezvauri kuona, galena imaminerari iri kudiwa zvakanyanya uye inozivikanwa pasi rese nemhando dzakasiyana dzekushandisa. Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezve galena.
