Bioleaching (los yog biomining) yog txheej txheem hauv mining thiab biohydrometallurgy (natural txheej txheem ntawm kev sib cuam tshuam ntawm microbes thiab minerals) uas rho tawm cov hlau muaj txiaj ntsig los ntawm cov ore qib qis nrog kev pab ntawm cov kab mob xws li kab mob los yog archaea.
Tsis tas li ntawd, cov kab mob dab tsi yog siv hauv bioleaching?
Bioleaching tuaj yeem koom nrog ntau cov ferrous hlau thiab sulfur oxidizing kab mob, suav nrog Acidithiobacillus ferrooxidans (yav tas los hu ua Thiobacillus ferrooxidans) thiab Acidithiobacillus thiooxidans (yav tas los hu ua Thiobacillus thiooxidans ). Raws li txoj cai dav dav, Fe3+ ions yog siv los oxidize cov ore.
Ib yam li ntawd, qhov txawv ntawm Biomining thiab bioleaching yog dab tsi? Biomining yog kev rho tawm ntawm cov hlau tshwj xeeb los ntawm lawv cov ores los ntawm kev siv tshuaj lom neeg, feem ntau cov kab mob. Bioleaching feem ntau hais txog biomining technology siv rau hauv cov hlau; whereas, biooxidation feem ntau yog siv rau sulfidic-refractory kub ores thiab concentrates.
Ib yam li ib tug yuav nug, qhov twg siv bioleaching?
Bioleaching yog siv Niaj hnub no hauv kev lag luam kev lag luam los ua cov hlau ntawm tooj liab, npib tsib xee, cobalt, zinc thiab uranium, whereas, biooxidation yog siv nyob rau hauv kub ua thiab thee desulfurization. Bioleaching Kev siv cov kab mob me me los ua kom cov oxidation ntawm hlau sulfides los tsim ferric sulfate thiab sulfuric acid.
Dab tsi yog microbial leaching?
Microbial ore leaching (bioleaching) yog txheej txheem ntawm kev rho tawm cov hlau los ntawm ore nrog kev siv kab mob . Txoj kev no yog siv los rov qab tau ntau yam khoom muaj txiaj ntsig zoo li tooj liab, txhuas, zinc, kub, nyiaj, thiab npib tsib xee. Cov kab mob siv vim lawv tuaj yeem: txo cov nqi tsim khoom.

Yuav ua li cas tshwm sim thaum magma txias thaum lub sij hawm lub pob zeb quizlet?
Raws li cov magma cools, loj thiab loj muaju tsim raws li lub pob zeb hardens. Yog tias magma tawm hauv lub ntiaj teb, lub pob zeb molten tam sim no hu ua lava. Thaum cov lava no txias rau ntawm lub ntiaj teb saum npoo, nws tsim cov pob zeb extrusive igneous. Lava txias sai heev, yog li cov pob zeb extrusive igneous tsis muaj crystals zoo
Yuav ua li cas koj paub thaum twg yuav siv cov khoom los yog quotient txoj cai?
Kev faib ua haujlwm. Yog li, thaum twg koj pom kev sib faib ntawm ob txoj haujlwm, siv txoj cai khoom thiab nyob rau hauv rooj plaub ntawm kev faib siv txoj cai quotient. Yog tias muaj nuj nqi muaj ob qho kev sib faib thiab faib, tsuas yog siv ob txoj cai raws li. Yog tias koj pom qhov sib npaug dav nws yog ib yam zoo li, qhov twg yog qhov ua haujlwm ntawm ib leeg
Yuav ua li cas cov thawj windings txuas thaum lub transformer yuav tsum tau ua nyob rau hauv ib tug 480 volt system?
Lub transformer muaj qhov polarity rho tawm thaum lub davhlau ya nyob twg H1 nyob ib sab ntawm lub davhlau ya nyob twg X1. Thaum lub 240/480 volt dual thawj tswj transformer yuav tsum tau ua los ntawm ib tug 240 volt system thawj winding yog kev cob cog rua nyob rau hauv parallel. Hauv Delta-connected transformer, theem thiab kab voltages sib npaug
Yuav ua li cas tshwm sim thaum tus txiv neej dig muag xim yuav ib tug poj niam ib txwm?
X qhia txog kev sib deev-txuas ntxiv cov noob rau xim dig muag. Yog hais tias tus txiv neej dig muag xim 0(Y) yuav poj niam ib txwm (XX), nyob rau hauv F1 tiam tag nrho cov txiv neej progeny (cov tub) yuav zoo li qub (XY). Cov poj niam progeny (cov ntxhais) tab sis yuav pom cov phenotype ib txwm, tab sis genetically lawv yuav heterozygous (XX)
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
