Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Kudzorerwa kwesimbi kuburikidza nekudzokorora kwava basa rinokosha reindasitiri yealuminium. Kudzokororazve kwaive chiitiko chakaderera kusvika mukupera kwema1960, apo kushandiswa kuri kuwedzera kwemabhokisi emvura yealuminium kwakaunza kune ruzivo rwevanhu. Kudzokororazve kunosanganisira kunyungudutsa zvimedu, chiitiko chinongoda 5% yesimba rinoshandiswa kugadzira aruminiyamu kubva mugoridhe, kunyange chikamu chakakosha (kusvika pa15% yezvinhu zvinoshandiswa) chinorasika semarara (madota-akafanana neoxide). An aluminium stack meltter inogadzira yakaderera zvakanyanya, iine kukosha kwakataurwa pazasi pe1%.White slag kubva kune yekutanga aluminium kugadzirwa uye kubva kune yechipiri yekudzokorora mashandiro ichiri iine huwandu hunobatsira hwealuminium iyo inogona kutorwa maindasitiri. Nzira yacho inogadzira aluminium billets, pamwe chete nemarara akaoma zvikuru. Marara aya akaoma kubata nawo. Inopindirana nemvura, ichibudisa musanganiswa wemagasi (kusanganisira, pakati pevamwe, hydrogen, acetylene, uye ammonia), iyo inoputika pakarepo painosangana nemhepo; kusangana nemhepo yakanyorova kunoguma nekusunungurwa kwemari yakawanda yegasi reammonia. Pasinei zvapo nezvinetso izvi, tsvina yacho inoshandiswa sechinhu chinozadza asphalt nekongiri.  Mubvunzo: Indasitiri ipi inokosha zvikuru kugadziriswazve?
