Qhov Tseem Ceeb Qhov txawv - Ferrous vs Non-Ferrous Minerals

Muaj ntau txhiab cov zaub mov uas tshwm sim hauv ntiaj teb. Lawv muaj ntau yam compositions thiab ntau yam kev siv. Ferrous thiab non-ferrous minerals yog ib qho ntawm cov kev faib tawm yooj yim tshaj plaws ntawm cov zaub mov raws li cov ntsiab lus hlau. Qhov sib txawv tseem ceeb ntawm ferrous thiab non-ferrous minerals yog lawv muaj pes tsawg leeg; ferrous minerals muaj hlau whereas non-ferrous minerals tsis muaj hlau. Txawm li cas los xij, ob qho tib si ntawm cov zaub mov no muaj qhov tshwj xeeb thiab tseem ceeb heev rau kev lag luam. Piv txwv ntawm cov zaub mov uas muaj hlau yog; Hematite (Fe₂O₃), Magnetite (Fe₃O₄), (FeCO₃), Pyrite (FeS₂), thiab Chalcopyrite (CuFeS₂). Copper (Cu), nyiaj (Ag), kub (Au) thiab Molybdenite (MoS_{2) yog ib co piv txwv rau cov minerals uas tsis yog-ferrous.}

Ferrous Minerals yog dab tsi?

ferrous cov zaub mov yog cov zaub mov muaj hlau (Fe) ua cov khoom hauv cov khoom xyaw. Qee cov zaub mov muaj hlau hauv qhov loj dua thaum qee cov zaub mov muaj hlau hauv qhov tsawg heev. Yog li ntawd, lawv tau siv los ua qhov chaw ntawm cov khoom sib txawv. Piv txwv li; Copper-iron sulphide (CuFeS₂) yog cov pob zeb loj tshaj plaws, Sphalerite (ZnFeS) yog ib qho ntawm zinc thiab hematite (Fe₂O _{3) yog qhov chaw hlau. Cov zaub mov no tuaj yeem pom nyob rau ntau qhov chaw ntawm lub ntiaj teb; ib txhia muaj tsawg heev, thiab ib txhia kuj muaj nyob rau hauv ib feem ntawm lub ntiaj teb no.}

Pyrite

Dab tsi yog cov ntxhia tsis-ferrous?

Non-ferrous minerals yog cov zaub mov uas tsis muaj hlau (Fe), thiab lawv muaj lwm cov ntsiab lus sib txawv, tshwj tsis yog ferrous. Cov zaub mov uas tsis yog-ferrous yog ib hom kev sib txawv uas muaj ntau ntau yam nyob rau hauv muaj pes tsawg leeg, tshwm sim thiab siv. Piv txwv ntawm cov minerals uas tsis yog-ferrous yog kub (Au), nyiaj (Ag), tooj liab (Cu) thiab lead (Pb). Lawv muaj nyob rau hauv ob qho tib si ntshiab los ntawm thiab nrog rau lwm yam minerals ua tebchaw. Cov zaub mov no yog qhov chaw ntawm ntau yam minerals rau kev lag luam.

Qhov tseem ceeb sib txawv - Ferrous vs Non-ferrous Minerals

Qhov txawv ntawm Ferrous thiab Non-Ferrous Minerals yog dab tsi?

Kev sib xyaw ntawm Ferrous thiab Non-Ferrous Minerals:

Ferrous Minerals: Ferrous minerals yog nyob rau hauv qeb ntawm metallic minerals; Tag nrho cov zaub mov no muaj hlau (Fe). Cov muaj pes tsawg leeg ntawm hlau txawv ntawm cov ntxhia mus rau ntxhia.

Non-ferrous Minerals: Non-ferrous minerals yog cov khoom siv hlau uas tsis muaj hlau (Fe). Lawv muaj ib lossis ntau dua lwm yam tshwj tsis yog hlau.

Piv txwv ntawm Ferrous thiab Non-Ferrous Minerals:

Ferrous Minerals:

Hematite: Fe2O3 (Iron Oxide)

Hematite yog ib qho ntawm cov hlau tseem ceeb tshaj plaws, thiab nws muaj ntau yam; hematite sawv, tsov hlau, raum ore, oolitic hematite thiab specularite. Cov hmoov hmoov ntawm hematite yog xim liab thiab siv los ua xim.

Magnetite: Fe_{3O4 (Iron Oxide)}

Magnetite yog cov xim dub nrog cov khoom sib nqus zoo.

Arsenopyrite: FeAsS (Iron Arsenide Sulfide)

Nws yog qhov chaw tseem ceeb ntawm arsenic.

Siderite: FeCO_{3 (Iron Carbonate)}

Siderite yog lo lus Greek rau hlau.

Pyrite: FeS_{2 (Iron Sulphide)}

Nws yog xim daj xim av nrog lub cubic qauv nrog striated nto. Qee tus neeg yuam kev qhov no yog kub rau nws cov xim. Yog li ntawd, nws tseem hu ua "Fool's Gold". Qhov no tuaj yeem pom hauv txhua qhov chaw.

Chalcopyrite: CuFeS_{2 (tooj liab-hlau sulphide)}

Nov yog cov pob zeb uas muaj tooj liab tshaj plaws. Cov ntxhia no muaj nyob rau hauv lwm yam minerals xws li sphalerite, galena, cassiterite thiab pyrite.

Non-ferrous Minerals:

Native Copper: (Cu)

Native tooj liab raug xa mus rau ib txwm tshwm sim ntawm daim ntawv tooj liab. Tooj liab yog ib qho ntawm cov hlau uas thawj zaug siv los ntawm tus txiv neej. Nws yog dav siv nyob rau hauv lub neej niaj hnub nyob rau hauv thiaj li muaj ntau yam kev siv. Nyob rau hauv yog ib txwm pom nyob rau hauv nrog yooj yim extrusive igneous pob zeb.

Gold:(Au)

Kub feem ntau pom nyob rau hauv daim ntawv ntshiab vim nws tsis tshua muaj cov sib txuas nrog lwm cov ntsiab lus. Nws yog feem ntau pom nyob rau hauv quartz leeg txuam nrog pyrites thiab lwm yam sulphides. Nws yog qhov nyuaj rau kev paub qhov txawv kub los ntawm kev pom kev pom; Nws raug kuaj pom siv tshuaj ntsuam xyuas.

Molybdenite: (MoS₂₎

Lub npe siv feem ntau rau Molybdenite yog "Moly"; Nws yog qhov feem ntau ntawm molybdenum ntxhia.
