Loj npaum li cas nyob txawv teb chaws Silicon-Magnesium Reserves?
Sab nraum Suav teb, txheeb xyuas silicon{0}}magnesium ore reserves yog kwv yees li ntawm 2.5 billion tonnes. Cov tonnage no tau kis thoob plaws Australia, Brazil, Canada, South Africa, Indonesia thiab ntau lub teb chaws me me. Vim tias magnesium-cov kabmob silicates thiab lawv cov pob zeb muaj pob zeb loj heev, cov khoom siv qis- cov khoom muaj nqis, lub zog ua lag luam ntawm lub hauv paus cia nyob deb ntau dua ntawm qib ore, sawb piv, lub zog muaj thiab nyob deb ntawm qhov chaw nres nkoj ntau dua li ntawm daim duab kab lus ib leeg.
Cov lus hauv qab no qhia txog cov ntaub ntawv khaws tseg feem ntau tau hais rau tsib qhov chaw ua haujlwm txawv teb chaws, suav nrog lawv thaj chaw mining tseem ceeb thiab lawv lub luag haujlwm hauv magnesium ferrosilicon mov saw.
| Lub teb chaws | Kwv yees li reserves (million t) | Cov cheeb tsam loj | Lub luag haujlwm hauv kev muab khoom |
|---|---|---|---|
| Australia | 500 | Western Australia | Loj - nplai ore thiab alloy feedstock |
| Brazil | 400 | Minas Gerais, Sao Paulo | Cov khoom siv hauv tsev thiab export alloy |
| Canada | 250 | Ontario, Quebec | Mature mining thiab processing puag |
| South Africa | 200 | Northern Cape, Mpumalanga | Thawj tus neeg tsim khoom African |
| Indonesia | 150 | Java, Sumatra, Kalimantan | Ceev- loj hlob hauv cheeb tsam qhov chaw |
Lub teb chaws -los ntawm - Lub Tebchaws Reserve Profile
Australiamuaj kwv yees li ntawm 500 lab tonnes, feem ntau ntawm nws nyob rau hauv Western Australia, thiab nws cov zis tau ntev nyob rau hauv lub siab tshaj plaws nyob rau hauv lub ntiaj teb no.Brazilsuav txog 400 lab tonnes hauv Minas Gerais thiab Sao Paulo, ze rau tsim txoj kev hauv tsev thiab chaw nres nkoj.Canadatshaj tawm qee qhov 250 lab tonnes hauv Ontario thiab Quebec, txhawb nqa los ntawm cov mining paub tab, txhim khu kev qha daim phiaj fais fab thiab kev paub txog metallurgical engineering.South Africatuav txog 200 lab tonnes hauv Northern Cape thiab Mpumalanga, lub hauv paus loj tshaj plaws nyob rau hauv teb chaws Africa.Indonesiamuaj nyob ib ncig ntawm 150 lab tonnes thoob plaws Java, Sumatra thiab Kalimantan thiab txuas ntxiv nthuav nws txoj haujlwm hauv cheeb tsam.
Los ntawm Ore Reserves rau FeSiMg Master Alloy
Reserve tonnage tsuas yog yuav pab tau rau lub foundry ib zaug nws hloov dua siab tshiab rau hauv ib tug tswj master alloy. Magnesium ferrosilicon, ib txwm sau FeSiMg, yog tus qauv spheroidizing tus neeg sawv cev rau cov hlau ductile: feedstock yog smelted, alloyed nrog silicon thiab magnesium, thiab feem ntau hloov nrog lub ntiaj teb tsis tshua muaj cov ntsiab lus kom cov tshuaj tiv thaiv nodularising nyob twj ywm kwv yees ntawm lub ladle. Ob lub ntsiab lus ua raws. Cov khoom siv txawv teb chaws muaj ntau, yog li cov khoom lag luam poob siab feem ntau yog los ntawm lub zog, kev thauj khoom lossis kev lag luam txoj cai es tsis yog geological scarcity; thiab magnesium thiab cov ntsiab lus tsis tshua muaj hauv ntiaj teb, tsis yog ore tonnage, txiav txim siab tus nqi ntawm qhov chaw tsim khoom tau txais.
Hom Rare Earth FeSiMg Nodulizer Qib
Magnesium nce los ntawm 5.5% mus rau 9.0% thiab tsawg lub ntiaj teb los ntawm 0.5% mus rau 7.5%, silicon yog tuav nyob rau hauv 40-46% band, calcium nyob ntawm 2.0-3.5%, barium yog matched rau cov kev kho mob xyaum, txhuas yog khaws cia hauv qab no 0.8% thiab hlau daim ntawv tshuav nyiaj li cas.

Yuav Ua Li Cas Ua Ntej Ua Ntej Kev Txiav Txim
Magnesium thiab lub ntiaj teb tsis tshua muaj ntau yam tiv thaiv txoj kev kho mob, ntu tuab thiab qib sulfur ntawm yaj.
Silicon cov ntsiab lus, uas cuam tshuam rau ob qho tib si magnesium rov qab thiab cov alloy ntxiv tus nqi.
Calcium, barium thiab txhuas txwv, vim tias cov kev hloov pauv slag tus cwj pwm thiab kev pheej hmoo suav nrog.
Particle loj tis, feem ntau 5-25 mm rau ladle ua hauj lwm, nrog nplua tsis tshua muaj.
Cov tshuaj sib xws los ntawm ntau mus rau ntau thiab cov qauv siv los ntawm kev ua haujlwm.
Cov lus nug nquag
Q: Ntau npaum li cas silicon{0}}magnesium ore muaj nyob sab nraum Suav teb?

Q: Lub teb chaws twg muaj qhov loj tshaj plaws txawv teb chaws cia?
Australia coj nrog kwv yees li 500 lab tonnes, feem ntau hauv Western Australia, tom qab ntawd Brazil nrog txog 400 lab tonnes.
Q: Puas yog qhov tshwj xeeb txiav txim siab tus nqi ntawm FeSiMg?
Tsuas yog indirect. Alloy nqi yog teem los ntawm magnesium thiab tsawg lub ntiaj teb cov ntsiab lus, lub zog thiab freight nqi, thiab conversion muaj peev xwm es tsis yog los ntawm ore tonnage.
Q: Tus lej hauv FeSiMg8RE5 txhais li cas?
Thawj daim duab yog cov ntsiab lus magnesium nominal ntawm 8% thiab qhov thib ob yog cov ntsiab lus nominal tsawg hauv ntiaj teb ntawm 5%; cov ntawv cim FeSiMg tsev neeg.
Q: Puas yog qib magnesium siab dua ib txwm zoo dua?
Tsis yog. Cov qhab nia saum toj no qhov kev kho mob tuaj yeem nqus tau cov tshuaj tiv thaiv kev ua phem, slag thiab magnesium poob, yog li qib yuav tsum ua kom haum cov txheej txheem.
