Dolostone cov ntaub ntawv thaum magnesium nyob rau hauv pore dej yog hloov rau qee cov calcium nyob rau hauv thawj limestone, los yog los ntawm dej nag ncaj qha. Feem ntau cov limestones ntawm kev lag luam tseem ceeb tau sau nyob rau hauv qhov chaw ntiav dej hiav txwv thiab muaj dav rau kev siv.
Dab tsi ua rau dolomite tsim?
Dolomite yog tsim los ntawm hloov cov calcite ions los ntawm magnesium ions. Nyob ntawm qhov sib piv ntawm Mg ions hauv cov iav siv lead ua lawv muaj cov npe sib txawv (Daim duab 1). Niaj hnub nimno dolomite tsim tau pom tshwm sim nyob rau hauv anaerobic tej yam kev mob nyob rau hauv supersaturated saline lagoons nyob rau hauv Brazil.
Dab tsi ua rau limestone tsim rau hauv dolostone?
Dolomite yog xav tsim thaum cov calcite (CaCO3) hauv carbonate av nkos lossis limestone yog hloov los ntawm magnesium-nplua nuj av hauv av. … Qhov kev hloov tshuaj no hu ua "dolomitization." Dolomitization tuaj yeem hloov cov pob zeb limestone rau hauv dolomite, lossis nws tuaj yeem hloov cov pob zeb los ua "dolomite limestone."
Dolostone tsim li cas?
Ib txheej txheem uas dolostone tuaj yeem tsim tau yog los ntawm txhais tau tias nag lossis daus ntawm calcium magnesium carbonate los ntawm dej hiav txwv. Lwm cov txheej txheem yog rau dolomite kom maj mam hloov cov calcite ntawm limestone tom qab cov limestone tau tso. Nyob rau hauv ob qho tib si, dolostone muaj ntau lub ntsiab magnesium dua li calcium.
Lub hom phiaj ntawm dolomite yog dab tsi?
Dolomite yog siv los ua qhov chaw ntawm magnesium hlauthiab ntawm magnesium (MgO), uas yog cov khoom siv ntawm cov cib refractory. Dolostone feem ntau yog siv los hloov limestone los ua ib qho sib xyaw rau ob qho tib si cement thiab bitumen sib tov thiab kuj yog ib qho flux nyob rau hauv blast furnaces.
