Kukosha kweKuongororwa kweZvicherwa zveQuality
Zvicherwa zvinhu zvakakosha muzvikamu zvakasiyana-siyana zvehupenyu hwevanhu uye maitiro echisikigo. Kuvapo kwazvo hakungogadziri chimiro chePasi chete asiwo kunoshanda senzvimbo yezvinhu zvekugadzira maindasitiri, simba, uye tekinoroji yemazuva ano. Zvisinei, chicherwa chisati chashandiswa nemazvo, danho rekutanga rakakosha nderekuziva mhando yechicherwa nemazvo. Apa ndipo panotariswa ongororo yezvicherwa zvine hunhu. Kuongorora kwehunhu kunovavarira kuona zvicherwa zvichibva pahunhu hwazvo, pasina kutanga kuverenga huwandu hwakadzama hwezvinhu kana huwandu hwazvo. Kunyange zvazvo zvinganzwika zviri nyore, ongororo iyi ndiyo hwaro hwekuita sarudzo mukutsvaga, kuchera, kugadzirisa, uye kudzora hunhu.
Kunzwisisa Kuongorora Kwemhando Yezvicherwa
Kuongorora zvicherwa zvemhando yepamusoro inzira yekuona kuti rudzii rwechicherwa chiri mumuenzaniso. Chinangwa chikuru hachisi pahuwandu hwechicherwa (ndiko kuti huwandu), asi pane kuziva chimiro chayo nehunhu hwayo: kana muenzaniso wacho uri quartz, calcite, pyrite, hematite, galena, kana chimwe chicherwa. Kuzivikanwa uku kunoitwa kuburikidza nekutarisa uye kuyedza hunhu hwepanyama, hwemakemikari, uye dzimwe nguva hwemineral-optical kana zvishandiso zviri nyore, zvichienderana nezvinodiwa uye kuwanikwa kwenzvimbo.
Kuongorora hunhu hwenzvimbo kazhinji inhanho yekutanga inokurumidza uye isingadhuri, kunyanya muongororo dzemumunda. Kuziva kwakarurama kunobvumira maitiro ekutevera akanyatsojeka akadai sekusarudza nzira dzekubvisa, kuona kukosha kwehupfumi, uye kuongorora kukanganisa kwezvakatipoteredza.
Sei Kuongorora Zvicherwa Kwemhando Yepamusoro Kwakakosha?
1. Hwaro hweSarudzo muKutsvaga neKuchera Migodhi
Panguva yekuongorora, timu ye geology inofanira kunzwisisa mhando dzezvicherwa zvakanyanya panzvimbo. Semuenzaniso, kuvapo kwemamwe mamineral e sulfide kunogona kuratidza kuti pane simbi dzakadai semhangura, zinc, kana lead. Pasina ongororo chaiyo yemhando, zvinangwa zvekutsvaga zvinogona kushaikwa, mari inogona kuwedzera, uye nguva inogona kutambiswa.
Munguva yekuchera, kuzivikanwa kwezvicherwa kunosarudzawo nzira dzekuburitsa matombo nekusarudza. Zvicherwa zvinokosha zvinowanzobatanidzwa netsvina (gangue). Nekuziva zvicherwa izvi, makambani anogona kugadzira nzira dzekuparadzanisa dzinoshanda, zvichikonzera mhedzisiro yekuchera inodhura zvakanyanya.
2. Sarudza Nzira Yakakodzera Yokugadzirisa
Chicherwa chimwe nechimwe chinopindura zvakasiyana pakugadzirwa. Semuenzaniso, goridhe rinogona kuvapo segoridhe risina kucheneswa kana kuvharirwa mukati memaminerari esulfide akadai sepyrite nearsenopyrite. Kana ongororo yemhando yepamusoro ikaona huwandu hwakawanda hwesulfide, nzira yekugadzirisa goridhe inogona kuda kugadziriswa kwakawedzerwa senge oxidation kana kugochwa usati waita cyanidation.
Mamiriro akafanana anoitika mukugadzirisa simbi: hematite nemagnetite zvinoda nzira dzakasiyana dzekuvandudza. Kusaziva zvicherwa zvisirizvo kunogona kutungamira munzira dzisingashande, kutambisa ma reagents, uye kudzoserwa kwadzo zvishoma.
3. Kudzora Hunhu Muindasitiri
Kuongorora zvicherwa zvine hunhu kwakakosha mumaindasitiri anoshandisa zvicherwa sezvinhu zvekugadzira, zvakaita sesimende, zvicherwa zvedongo, magirazi, pendi, fetereza, nemishonga. Semuenzaniso, muindasitiri yesimende, hunhu hwezvicherwa zve limestone nevhu hunokanganisa kunaka kwe clinker. Kuwanda kwetsvina kunogona kukanganisa chigadzirwa chekupedzisira kana kuda kugadziriswa kwemaitiro ekugadzira.
Muindasitiri yezvesimbi, kuvapo kwezvimwe zvicherwa kunogona kukanganisa ruvara rwechigadzirwa, pokunyunguduka, maburi, uye simba racho. Saka, kuzivikanwa kwezvicherwa nekukurumidza kunobatsira kuchengetedza mhando dzakafanana uye kuderedza zvikanganiso zvechigadzirwa.
4. Kutsigira Kuchengetedzeka Nehutano Pabasa
Zvimwe zvicherwa zvinogona kuisa njodzi kuhutano. Mienzaniso inozivikanwa zvikuru ndeye asbestos minerals dzakadai sechrysotile kana mamwe maamphiboles, ane fibers inokuvadza kana ikafemerwa. Crystalline silica (semuenzaniso, quartz) muguruva remugodhi inogonawo kukonzera silica. Kuongorora kwehunhu kunobatsira kuona kuvapo kwezvicherwa zvine njodzi nekukurumidza kuitira kuti makambani agone kushandisa nzira dzakakodzera dzekudzivirira guruva, michina yekudzivirira, uye maitiro ekushanda.
Nemamwe mashoko, kuzivikanwa kwezvicherwa hakusi kwezvehupfumi chete, asiwo kuchengetedzeka kwevashandi nenharaunda yakapoteredza.
5. Zvakakosha pakudzidza nezvezvakatipoteredza uye pakugadzirisa zvakare
Mukuchera, kuvapo kwezvicherwa zvesulfide zvakaita sepyrite kunogona kukonzera kubuda kwemvura mumigodhi ine acid kana yasanganiswa nemvura. Izvi zvinogona kukanganisa nharaunda dzemumvura nedzevhu. Kuongorora kwemhando yepamusoro kunogona kufanotaura mukana wekubvisa mvura mumigodhi ine acid, zvichibvumira matanho ekudzivirira nekuderedza njodzi kuti agadziriswe panguva yekuronga.
Pamusoro pezvo, mukudzoreredza ivhu, kunzwisisa mineralogy kunobatsira zvikuru pakusarudza rudzi rwevhu rakavharirwa, nzira dzekugadzirisa, uye kusarudzwa kwemiti yakakodzera.
Nzira Dzakajairika dzekuongorora hunhu hwezvicherwa
Kuongororwa kwemhando yemaminerari kunogona kuitwa nenzira dzakasiyana-siyana, kubva pazviri nyore kusvika pakushandisa zvishandiso:
1. Kucherechedza zvivakwa zvemuviri
- Ruvara, kupenya, chimiro chekristaro
– Kuoma (chikero cheMohs)
- MaHemispheres nezvikamu
- Simba remagetsi rakafanana
- Simba remagineti
2. Bvunzo iri nyore yemunda
- Bvunzo rekukwenya
- Kuedza mitsetse (ruvara rwemitsetse iri pamaplate eporcelain)
– Kuita nemaacids (semuenzaniso calcite furo ine diluted HCl)
- Kutarisa negirazi rinokudza zvinhu (girazi rinokudza zvinhu)
3. Kumwe kuongorora kwezvicherwa
- Maikorosikopu inoparadzanisa (petrography) yezvicherwa zvinoonekera
- Kuongororwa kwekutarisa kwezvicherwa zvisingaonekwe (semuenzaniso sulfides)
4. Nzira dzekutsigira dzekushandisa
– XRD (X-Ray Diffraction) yekuziva zvikamu zvekristaro
- SEM-EDS ye morphology uye qualitative elemental composition
- Spectroscopy chaiyo yekuzivikanwa nekukurumidza mumamiriro ezvinhu akakosha
Kunyange zvazvo zvimwe zvishandiso zvinosanganisira ongororo yakadzama, chinangwa chekutanga chinowanzo ramba chiri chemhando yepamusoro: kuona kuti zvicherwa zvipi zviri mumuenzaniso.
Matambudziko muKuongorora Hunhu hweZvicherwa
Kuongorora hunhu hwezvinhu hakusi nyore nguva dzose. Zvicherwa zvinogona kuva nemavara akafanana asi zvine maumbirwo akasiyana. Semuenzaniso, pyrite inowanzo fungidzirwa segoridhe nevanhuwo zvavo nekuda kwekupenya kwayo kwakafanana. Uyezve, zvicherwa zvinogona kuvapo sema alloys akapfava, kuchinjwa, kana kufukidzwa ne oxide layers, zvichichinja hunhu hwazvo uye zvichiita kuti zviome kuzivikanwa.
Saka, musanganiswa wenzira dzinodiwa: kucherechedza mumunda, ruzivo rwekuita, uye kusimbiswa nebvunzo dzemurabhoritari kana zvichidikanwa. Kururama uye kunzwisisa mamiriro enzvimbo yejeologiya zvakakoshawo.
Mhedziso
Kuongorora zvicherwa zvine hunhu hwakanaka idanho guru mukunzwisisa zviwanikwa zvechisikigo uye kutarisira mashandisirwo azvo nemazvo. Basa rayo rinobva pakutsvaga nekuchera, kugadzira matombo, kudzora mhando dzemaindasitiri, kusvika kuchengetedzeka kwebasa nekuchengetedzwa kwezvakatipoteredza. Kuzivikanwa kwezvicherwa nemazvo kunotungamira kusarudzo dzakarurama dzehunyanzvi, mitengo yakaderera, njodzi dzinodzorwa, uye kuderedzwa kwekukanganisa kwezvakatipoteredza.
Pakati pekudiwa kuri kukura kwezvicherwa zvekuvandudza zvivakwa, simba rinogona kushandiswazve, uye tekinoroji yemazuva ano, kugona kuita ongororo yezvicherwa zvine hungwaru kuri kuramba kuchikosha. Iri harisi danho rekutanga mukuita kwezvicherwa, asi hwaro hwakakosha hwekuona kuti danho rega rega rinotevera—ringave resainzi, remaindasitiri, kana remitemo—rakavakirwa padata rakarurama uye rakavimbika.
Kana muchida, ndinogona kugadzirisa chinyorwa chino kuita pepa resainzi (rine pfupiso, sumo, nzira, hurukuro, mhedziso, uye mabhuku ekuverenga) kana kuwedzera mienzaniso chaiyo kubva mumigodhi/indasitiri muIndonesia.
