tooj liab mining feem ntau yog ua los ntawm kev qhib qhov mining, uas muaj ntau lub rooj zaum zaum tau khawb tob thiab tob rau hauv lub ntiaj teb dhau sijhawm. Txhawm rau tshem tawm cov ore, boring machinery yog siv los tho qhov rau hauv cov pob zeb tawv, thiab cov khoom tawg tau muab tso rau hauv qhov tho qhov kom tawg thiab tawg pob zeb.
Yuav ua li cas rho cov tooj liab?
Ua ntej, cov ore yog kho nrog dilute sulfuric acid. Qhov no maj mam dhau los ntawm cov ore, dhau ib lub hlis, yaj tooj liab los tsim cov tshuaj tsis muaj zog ntawm tooj liab sulphate. Tus tooj liab yog rov qab los ntawm electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).
Yuav ua li cas cov ntxhia yog tooj liab rho tawm los ntawm?
Ntau lub ntiaj teb tooj liab yog los ntawm cov zaub mov chalcopyrite thiab chalcocite. Chrysocolla thiab malachite kuj yog mined rau tooj liab.
pob zeb yog tooj liab nyob hauv dab tsi?
tooj liab thiab ores muaj nyob rau hauv ob qho tib si igneous thiab sedimentary pob zeb.
tooj liab feem ntau pom nyob qhov twg?
Lub pob zeb loj tshaj plaws nyob hauv Utah (Bingham Canyon). Lwm qhov mines loj muaj nyob hauv Arizona, Michigan, New Mexico thiab Montana. Hauv South America, Chile, lub ntiaj teb cov neeg tsim khoom loj tshaj plaws, thiab Peru yog ob qho tib si loj tsim tooj liab.
