Qhov sib txawv tseem ceeb ntawm biomining thiab bioleaching yog biomining yog cov txheej txheem ntawm kev siv prokaryotes lossis fungi los rho tawm cov hlau los ntawm cov zaub mov whereas bioleaching yog cov txheej txheem ntawm kev siv cov kab mob los rho tawm cov hlau los ntawm cov zaub mov.
Muaj ntau ntau txoj hauv kev uas tuaj yeem siv los rho tawm cov hlau los ntawm lawv cov ore lossis cov khib nyiab pov tseg. Feem ntau ntawm cov txheej txheem no siv tshuaj reagents rau qhov kev rho tawm. Yog li ntawd, kev puas tsuaj los ntawm cov khoom lag luam thiab kev puas tsuaj rau ib puag ncig yog ib qho teeb meem nrog cov txheej txheem no. Biomining thiab bioleaching yog cov txheej txheem uas siv los rho tawm cov hlau los ntawm lawv cov ore los ntawm kev muaj sia nyob.
YBiomining yog dab tsi?
Biomining yog ib qho txheej txheem uas peb tuaj yeem siv los rho tawm cov hlau los ntawm lawv cov ore siv prokaryotes thiab fungi. Yog li ntawd, qhov no yog ib txoj kev kho mob lom uas siv cov kab mob nyob. Nyob rau hauv cov txheej txheem no, cov kab mob microorganisms secrete organic tebchaw uas muaj peev xwm chelate cov hlau nyob rau hauv cov hlau ore. Tom qab ntawd, lawv zoo li uptake lub coordinate complex nrog rau cov hlau chelated rau hauv lub cell ntawm cov kab mob. Qee cov kab mob tuaj yeem siv cov hlau ions xws li hlau, tooj liab, zinc, kub, thiab lwm yam. Qee lub sij hawm, peb tuaj yeem soj ntsuam qee cov kab mob microorganisms uptake, txawm tias cov hlau tsis ruaj khov, xws li uranium thiab thorium.
Daim duab 01: Copper Mining
Piv rau cov mining ib txwm, uas tso tawm cov khoom puas tsuaj lossis tshuaj lom rau ib puag ncig, biomining yog cov txheej txheem zoo ib puag ncig. Cov byproducts uas tso tawm los ntawm biomining yog metabolites thiab gases uas cov microorganisms tsim. Cov kab mob no tuaj yeem siv rov ua dua.
Daim duab 02: Kub Heap Leaching
Kev siv ntau tshaj plaws ntawm biomining yog kub mining. Peb tuaj yeem pom cov kub hauv cov xwm txheej nrog rau lwm cov zaub mov uas muaj arsenic thiab pyrite. Ntawm no, cov kab mob tuaj yeem yaj cov zaub mov pyrite siv lawv cov secretions thiab, hauv cov txheej txheem no, kub tso tawm. Raws li qhov tseem ceeb ntawm biomining yog qhov tseem ceeb kom tshem tawm cov hlau hnyav hnyav los ntawm qhov xwm txheej.
YBioleaching yog dab tsi?
Bioleaching yog txoj kev rho tawm cov hlau los ntawm lawv cov ore siv cov kab mob muaj sia xws li cov kab mob. Yog li, cov txheej txheem no yog huv si thiab ib puag ncig zoo dua li cov txheej txheem heap leaching uas siv cyanide. Txoj kev no tseem ceeb heev hauv kev rho tawm cov hlau xws li tooj liab, zinc, lead, arsenic, antimony, nickel, thiab lwm yam.
Ib qho piv txwv yog pyrite ntxhia leaching. Cov txheej txheem no suav nrog ntau hom hlau-sulfur oxidizing kab mob. Feem ntau, cov txheej txheem ntawm bioleaching suav nrog cov kauj ruam pib uas ferric ions siv los oxidize cov hlau ore. Ntawm no, ferric ions raug txo kom ferrous ions. Cov kauj ruam no tsis koom nrog microbes. Yog li ntawd, cov kab mob yog siv rau oxidation ntxiv ntawm cov hlau ore. Nyob ntawd, cov kab mob tau siv los oxidize sulfur thiab hlau hauv cov hlau ore.
Qhov txawv ntawm Biomining thiab Bioleaching yog dab tsi?
Biomining thiab bioleaching yog cov txheej txheem siv los rho tawm cov hlau los ntawm lawv cov ore los ntawm cov kab mob nyob. Qhov sib txawv tseem ceeb ntawm biomining thiab bioleaching yog biomining yog cov txheej txheem ntawm kev siv prokaryotes los yog fungi kom rho tawm cov hlau los ntawm cov zaub mov whereas bioleaching yog cov txheej txheem ntawm kev siv cov kab mob kom rho tawm cov hlau los ntawm cov zaub mov.
Hauv qab infographic qhia txog qhov sib txawv ntawm biomining thiab bioleaching.
Summary – Biomining vs Bioleaching
Biomining thiab bioleaching yog cov txheej txheem uas siv los rho tawm cov hlau los ntawm lawv cov ore los ntawm cov kab mob nyob. Qhov sib txawv tseem ceeb ntawm biomining thiab bioleaching yog biomining yog cov txheej txheem ntawm kev siv prokaryotes los yog fungi kom rho tawm cov hlau los ntawm cov zaub mov whereas bioleaching yog cov txheej txheem ntawm kev siv cov kab mob kom rho tawm cov hlau los ntawm cov zaub mov.
