Qhov Tseem Ceeb Qhov txawv – Metallic vs. Nonmetallic Minerals
A ntxhia yog ib yam khoom uas tshwm sim thiab inorganic nrog cov qauv tshuaj tseeb thiab muaj cov qauv siv lead ua. Lawv yog cov khoom siv geological uas yog mined rau lawv cov nyiaj txiag thiab kev lag luam. Lawv yog siv nyob rau hauv lawv tej yam ntuj tso daim ntawv los yog tom qab kev sib cais thiab purification los yog raw cov ntaub ntawv los yog cov khoom xyaw nyob rau hauv ib tug ntau yam ntawm daim ntaub ntawv. Theses minerals yuav muab faib ua ob pawg loj, thiab lawv yog metallic minerals thiab non-metallic minerals. Lub ntiaj teb yog tsim los ntawm kev sib xyaw ntawm cov hlau thiab cov hlau tsis yog hlau. Txawm li cas los xij, cov ntsiab lus nonmetallic muaj ntau dua li cov khoom siv hlau. Qhov sib txawv tseem ceeb ntawm cov khoom siv hlau thiab cov hlau tsis yog hlau yog cov hlau tsis muaj hlau yog qhov sib xyaw ntawm cov ntxhia uas tuaj yeem yaj tau kom tau txais cov khoom tshiab thaum cov hlau tsis yog hlau yog kev sib xyaw ntawm cov ntxhia uas tsis tsim cov khoom tshiab ntawm melting. Tsis tas li ntawd, metallic minerals feem ntau yog muab los ntawm ores whereas nonmetallic minerals yog muab los ntawm industrial pob zeb thiab minerals. Kab lus no tshawb txog txhua yam tshuaj thiab lub cev sib txawv ntawm cov khoom siv hlau thiab cov hlau tsis yog hlau.
Metallic Minerals yog dab tsi?
Metallic minerals tsuas yog cov ntxhia uas suav nrog ib lossis ntau lub ntsiab lus hlau. Lawv feem ntau muaj glossy nto, yog cov conductors ntawm tshav kub thiab hluav taws xob, thiab tuaj yeem raug pounded rau hauv cov ntawv nyias lossis ncab rau hauv cov xov hlau. Lawv tsuas yog siv los ua cov cuab yeej thiab riam phom. Cov ntxhia hlau yog tso rau hauv kub nuggets, thaj chaw volcanic, sedimentary pob zeb thiab cov dej kub. Thaum cov khoom siv hlau raug khawb, lawv hu ua ores, thiab ores yuav tsum tau ua haujlwm ntxiv kom cais cov hlau. Ua ntej cov ore yog crushed thiab tom qab ntawd cov khoom siv hlau yog cais los ntawm cov pob zeb uas tsis xav tau los ua kom pom tseeb. Cov hlau no mloog zoo ces yuav tsum tau muab cais tawm ntawm cov khoom tsis yog hlau los yog lwm yam impurities. Piv txwv ntawm cov khoom siv hlau yog chalcopyrite (CuFeS2), Kub, Hematite (Fe2O3), Molybdenite (MoS2), Native tooj liab (Cu), Pyrite (FeS2), thiab Sphalerite (Zn, FeS).
Chalcopyrite
Non-metallic Minerals yog dab tsi?
Cov zaub mov tsis yog xim hlau yog ib txwm tshwm sim ua ke ntawm cov tshuaj lom neeg uas feem ntau tsis muaj cov yam ntxwv ntawm cov xim hlau. Cov zaub mov no feem ntau muaj xws li carbon, phosphorus, sulfur, selenium, thiab iodine. Piv txwv ntawm cov minerals uas tsis yog xim hlau yog limestone, dolomite, magnesite, phosphorite, talc, quartz, mica, av nplaum, silica xuab zeb, gemstones, hniav thiab dimension pob zeb, cov khoom siv, thiab lwm yam. Cov minerals uas tsis yog xim hlau yog keeb kwm hauv pob zeb, ores, thiab pob zeb. Pob zeb tuaj yeem ua tiav ntawm cov khoom siv tsis yog ntxhia. Piv txwv li, thee yog lub pob zeb sedimentary uas tsim los ntawm cov pa roj carbon monoxide. Lub pov haum pob zeb feem ntau muaj nyob hauv ntau lub pob zeb sib txawv, piv txwv li, ruby thiab sapphire, thiab lwm yam.
Sapphire
Dab tsi yog qhov txawv ntawm Metallic thiab Nonmetallic Minerals?
Melting:
Metallic minerals tuaj yeem yaj kom tau txais cov khoom tshiab.
Non-metallic minerals tsis tsim cov khoom tshiab ntawm melting.
Kub thiab hluav taws xob:
Metallic minerals yog cov conductors zoo ntawm tshav kub thiab hluav taws xob.
Cov ntxhia tsis yog xim hlau yog cov rwb thaiv tsev zoo ntawm cov cua sov thiab hluav taws xob thiab cov khoom tsis zoo ntawm cov cua sov thiab hluav taws xob.
Natural Abundance:
Ores muaj cov ntsiab lus siab ntawm cov khoom siv hlau.
Pob zeb thiab lub pov haum muaj cov ntsiab lus siab ntawm cov pob zeb tsis yog hlau.
Abundance:
Metallic minerals tsawg abundance piv rau non-metallic minerals.
Non-metallic muaj ntau dua piv rau cov khoom siv hlau.
Zoo:
Metallic minerals muaj ci los yog ci zoo li.
Cov ntxhia tsis yog xim hlau muaj qhov zoo li submetallic lossis dull. Tab sis lub pov haum pob zeb muaj qhov ntxim nyiam, xim tshwj xeeb.
Lub cev muaj zog:
Metallic minerals yog ductile lossis malleable thiab thaum ntaus, lawv tsis tau tawg mus rau hauv daim.
Cov ntxhia tsis yog xim hlau tsis yog ductile thiab malleable, tab sis lawv nkig, thaum ntaus, lawv yuav tawg mus rau hauv daim. Tab sis muaj qee qhov kev zam xws li silica, gemstones thiab pob zeb diamond.
Examples:
Metallic minerals feem ntau cuam tshuam nrog cov pob zeb tsis zoo xws li hlau, tooj liab, bauxite, tin, manganese, chalcopyrite (CuFeS 2), Kub, Hematite (Fe2O 3), Molybdenite (MoS2), Native tooj liab (Cu), Pyrite (FeS2), thiab Sphalerite (Zn, FeS).
Cov zaub mov tsis yog xim hlau feem ntau cuam tshuam nrog cov pob zeb sedimentary xws li thee, ntsev, av nplaum, marble, limestone, magnesite, dolomite, phosphorite, talc, quartz, mica, av nplaum, silica xuab zeb, gemstones, hniav thiab dimension pob zeb. Cov khoom siv, kaolin, brine, calcite, lignite, limonite, mica, potash, pob zeb phosphate, pyrite, radioactive minerals, soapstone, sulfur, pob zeb ntsev, vermiculite thiab sulphur.
