Zvemukati
MutungamiriPb) inyoro, ductile uye inonyorova simbi yetafura ye periodic iripo mune zvakasikwa.
Inowanikwa kupi?
Yakawanda yesimbi iyi inocherwa pasi pevhu. Nekudaro, izvi hazvisi mune yaro yepasi mamiriro, saka kune zvinopfuura makumi matanhatu zvesimbi zvinogona kuve nemutobvu, asi kune matatu chete esimbi ayo anoshandiswa kutora lead: galena, cerussite uye anglesite. Chekupedzisira, zvakakosha kutaura kuti iko kushandiswa kukuru kwemutobvu kugadzirwa kwemabhatiri anodzoreka.
Iyo zvicherwa kubva kunotora zvakanyanya kutorwa igalena, uko kwainowanikwa se lead lead sulfide. Nekudaro, ichi chicherwa chine 85% lead uye zvimwe zvese nesarufa. Kune madhiri egalena kuGerman, Mexico, United States, Spain neAustralia.
Midziyo inoshandiswa kubvisa lead kubva galena, uko ore yakaverengerwa uye oxide inoderedzwa kusvikira iyo sulfide chikamu chemutobvu chashandurwa kuita lead oxide uye sulfate.
Kana lead ichinge yaiswa muvira necccination mune ino maitiro, zvinosvibisa zvakawanda zvinosunungurwa: bismuth, arsenic, cadmium, mhangura, sirivheri, goridhe uye zinc. Mushure mekutora simbi yakanyungudutswa muvira rinogamuchira zita rereberberatory chiraga nemhepo, sarufa nemhepo, izvi zvinokwanisa kusanganisa simbi kunze kwegoridhe, sirivheri uye bismuth. Izvo zvakasara zvinosvibisa zvinoyangarara semarara zvinobviswa muchiitiko ichi.
Chii chimwe:
- Oiri inobviswa kupi?
- Aruminiyamu inowanikwa kupi?
- Simbi inotorwa kupi?
- Mhangura inotorwa kupi?
- Ndarama yakawanikwa kupi?
Tungamira kunatsa
Pine, lime, xanthate uye alum mafuta zvinowanzo shandiswa. Limestone kana ores ores anoshandiswa mukubika maitiro. Izvi zvinovandudza nzira yekubheka.
Recycling
Zvisinei, havasi vatungamiri vose vanobva kumigodhi. Chete 50% yekuwana kwekutungamira inotorwa kubva ipapo; iyo imwe 50% inouya kubva mukudzokororazve mota dzinounganidza (mabhatiri).
