I. Dab tsi yog qhov tsis muaj metallic minerals
Cov me nyuam yaus tsis yog xim hlau xa mus rau qee yam tsis yog xim hlau uas muaj txiaj ntsig kev lag luam uas muaj peev xwm siv tau qee yam kev siv hluav taws xob, lub cev lossis cov pob zeb. Tuam Tshoj yog nplua nuj nyob rau hauv tsis yog xim hlau ntxhia cov khoom siv, nrog ntau yam thiab kev faib tawm dav dav. Tag nrho ntawm 95 hom tsis yog xim hlau caterals tau pom thoob plaws lub tebchaws.
Ii. Dab tsi yog cov tsis muaj metallic minerals
Metallurgical cov khoom siv cov zaub mov muaj: xws li magnesite, refractory av nplaum, silica, doloma, dolomite, fluorite, thiab lwm yam.
2. Tshwj xeeb tsis yog xim hlau cov zaub mov: xws li pob zeb diamond, quartz, iceland kev txhaum, Mica, Ncig xyuas thiab lwm yam.
3. Qhov tsis muaj metallic cov zaub mov: xws li phosphorus, sulfur, cov ntsev ua kua, mirabilite, av siv quav ciab, thiab lwm yam av.
4. Lub tsev cov ntaub ntawv: xws li Basalt, Granite, Marble, Gypsum, thiab lwm yam.
5. Ceramic thiab iav raw khoom: xws li kaolin, av nplaum av nplaum, quartz xuab zeb, felpspar, thiab lwm yam.
6. Qhov tsis muaj metallic minerals rau kev ua yeeb yam thiab cov khoom siv tes ua, lub pob zeb, Phocky, Phocky Quartz, Pawm kib, Iceland kev txhaum, Iceland kev txhaum, inkstone, thiab lwm yam.
7. Lwm cov ntaub ntawv: xws li vermiculite, pumice, diatomite, asbestos, graphite thiab lwm yam.
III. Ua rau ntawm kev tsim ntawm qhov tsis muaj metallic minerals
Qhov ua rau ntawm cov me nyuam me me yog muaj sib txawv, tab sis magmatic, metamorphic, sedimentary thiab hom tseem ceeb tshaj plaws. Tsis tas li ntawd, submarine Dav Dav Flow kuj tseem tseem ceeb. Piv txwv li, pyrite feem ntau yog rau hom kev ua rau no.
Magmatic kev ua ub no
Lub Volcanic Lava, volcanic tshauv thiab lwm cov ntaub ntawv tsim los ntawm upward intrusion ntawm cov pob zeb loj los yog tom qab tawg tau txhua daim hlau tsis yog xim hlau. Cov pob zeb loj xws li grey feldspar thiab granite tuaj yeem siv raws li cov ntaub ntawv zoo hauv tsev. Lub ntsej muag "General lub qhov ncauj" pem teb granite hauv Suav teb thiab "Indian liab" granite "granite" granite yog ob lub poov tshuaj feldsppar granites. Pumice thiab perlite tsim los ntawm kev ejection rau saum npoo yog ob qho tseem ceeb indispensable cov ntaub ntawv raw, thiab cov hmoov tshauv volcanic tseem tuaj yeem siv ua cov chiv ua liaj ua teb. Kuj tseem muaj ob hom neeg tshwj xeeb ntawm cov pob zeb tsis zoo thiab cov poov xab thiab cov poov tshuaj-lamassium yaj, uas muaj cov pob zeb diamond ntau tshaj sab hauv. Feem ntau ntawm cov pob zeb diamond hauv ntiaj teb yog tsim nyob rau hauv ob hom pob zeb.
2. Metamorphism
Thaum pob zeb yog nyob rau hauv lub xeev ruaj khov, lawv yauv hloov pauv hauv cov ntxhia, pob zeb hauv qab kub, yog li ua cov xim tsis muaj hlau. Cov ntaub ntawv uas nquag siv rau hauv kev lag luam thiab txhua hnub lub neej suav nrog cov kab mob rutile, thiab lwm yam, yog txhua qhov chaw paub txog kev paub hauv tuam tsev ntau lawm.
3. Kev Ua Si
Pob zeb thiab cov tshuaj ore lub cev raug rau saum npoo av, nyob rau hauv lub sijhawm ntev ntawm cov huab cua thiab dej ntws, kev thauj mus los, nws thiaj li tsim cov khoom siv hlau tsis sib xws. Lawv tuaj yeem sau ncaj qha foos tsis yog xim hlau cov ntxhia txheej los ntawm cov nag los nag thiab cov txheej txheem biochemical. Nws feem ntau muab faib ua peb pawg: (1) tsuas yog tsim los ntawm kev sib cais ntawm cov dej ntws, thiab cov huab cua, cua hlob tuaj yeem ua rau txhua tus txheej txheem no. (2) Cov txheej txheem biochemical, xws li phosphate pob zeb tau tsim los ntawm kev sib txuam ntawm cov noog uas muaj kev sib txuam, thiab lwm yam (ntawm ntsev thiab ntsev thiab ntsev thiab ntsev Hauv kev ua liaj ua teb
4. Weathering
Pob zeb los yog ore lub cev raug rau saum npoo av, tom qab tus txheej txheem dej nag, hloov cov tshuaj lom neeg, hloov cov ntaub ntawv tsis yog xim hlau uas tuaj yeem siv tau. Cov av nplaum minerals tsis pom nyob rau hauv lub neej txhua hnub thiab kev lag luam feem ntau yog tsim los ntawm qhov laj thawj no. Piv txwv li, Kaolin thiab Bentonite yog txhua tus tsim los ntawm cov huab cua ntawm cov pob zeb. Nws yog qhov tseeb tus txheej txheem no uas muaj cov ntaub ntawv raw rau tib neeg los ua ceramics, tshuaj pleev ib ce, tshuaj thiab lwm yam tshuaj. Saib nws los ntawm kev pom dav dav, txawm tias cov av nyob rau txhua yam muaj sia nyob ntawm kev muaj sia nyob yog qhov tsis muaj metallic cov khoom tsim los ntawm huab cua.
