Ukukhupha i-Magnesium echanekileyo esuka kwiCore lomhlaba
I-Magnesiyumu yinto yesibhozo ebonakalayo ebonakalayo kwindalo yonke kwaye eyesixhenxe iyona eqhelekileyo kwi-Earth crust. Inokusetyenziswa kweentlobo ezahlukeneyo kwishishini kwaye liyinto ebalulekileyo kumayeza. Ngokuqhelekileyo kusetyenziswa njenge-alloy e-aluminium; Ukongezwa kwe-magnesium kugqithisa ubunzima be-aluminium ngaphandle kokuchaphazela kakubi umatshini wakhe, iimveliso kunye neempawu zokuhambisa. I-Magnesiyam isetyenziswa kwakhona kwi-pyrotechnics kwaye inokukunceda ukuvuselela isisu.
Nangona kunjalo ukuba kulula ukuyifumana, i-magnesium ayifumaneka inkululeko kwimvelo. Ngenxa yoko, iindlela ezininzi ezahlukeneyo ziye zaphuhliswa ukuze zihlukanise i-magnesium kwezinye izinto.
I-Technique yokuvelisa iMagnesium
Ngokuxhomekeke kwindawo kunye nohlobo lwesityebi esisetyenzisiweyo, iindlela ezahlukeneyo zokuvelisa zingasetyenziselwa ukucokisa i- magnesium zetsimbi. Oku kungenxa yezinto ezimbini. Okokuqala, i-magnesium ininzi kakhulu, eyenza ukuveliswa kwiindawo ezininzi kunokwenzeka. Okwesibini, izicelo zokuphela kokusetyenziswa kwazo zixabiso lentengo, okukhuthaza ukuba abathengi bahlale befuna umthombo wexabiso eliphantsi kakhulu.
Ukukhutshwa kwi-Dolomite ne-Magnesite Ore
Iinkqubo ze-Electrochemical zisetyenziselwa ukukhipha isinyithi kwi-dolomite kunye ne-ore magnesite. Xa i-dolomite ichithwe, igalelwe kwaye ixutywe namanzi olwandle kwiitanki ezinkulu, i-magnesium hydroxide ihlala phantsi. Ukutshaya, ukuxuba kwi-coke, nokuphendula nge-chlorine, ize ivelise i-magnesium chloride.
Oku kunokwenziwa i-electrolyzed, ukukhulula i-magnesium, ejikeleza phezulu.
Ukukhutshwa kwiLwandle loTyuwa
I-Magnesium iphinda ikhutshwe kwietyuwa zetyuwa, equle malunga neepesenti ezili-10 ze-magnesium chloride. I-magnesium chloride kule mimithombo iqukethe amanani amaninzi amanzi kwaye kufuneka imiswe ukwenzela ukuba i-magnesium chloride i-anhydr, ngaphambi kokuba ifakwe i-electrolyzed ukuvelisa isinyithi.
Amanzi enzentyambo anokukwazi ukuba nomgangatho ophezulu we-magnesium. Insimbi yokuqala ye-magnesium ekhishwe ngamanzi olwandle yaveliswa yiDow Chemicals kwi-Freeport, eTexas isityalo ngo-1948. Isixhobo sase-Freeport sasebenza kude kube ngo-1998, kodwa okwangoku, umvelisi we-magnesium osele usawolo kuphela oLwandle Olufile oluneMagnesium Ltd. ); I-joint venture phakathi kwe-Israel Chemicals Ltd. kunye neVolkswagen AG.
Ukukhutshwa ngePidgeon Process
Kule minyaka engama-20 edlulileyo, enye yezona ndlela zincinci zokuvelisa i-magnesium, i-oddly, ibe yinto exhaphakileyo. Inkqubo yePidgeon, ephuhliswe nguDkt. Lloyd Pidgeon, ibini ifom ye-energy and labour of reductional thermal.
Kule nkqubo, ukuphela komva , i- nickel - chromium- steel alloy reports zizaliswa ngumxube we-calcined dolorite ore kunye ne-ferrosilicon, ezitshiswayo kuze kube yimihlobiso ye-magnesium. Umjikelezo ngamnye uthatha malunga neeyure eziyi-11, kufuneka ugcwalise ngokuzenzekelayo nokukhupha iibhubhu zokucoca, kwaye usebenzise malunga neetoni ezili-11 zezinto ezibonakalayo kwiitoni nganye ze-magnesium eziveliswayo.
Isizathu sokusetyenziswa ngokubanzi kwePidgeon Inkqubo ngenxa yokutshintshwa kwemveliso kumaphondo a-acebile amalahle angasenyakatho-ntshona yaseChina apho iindleko zabasebenzi nezamandla ziphantsi kakhulu kunezinye iindawo zokuvelisa i-magnesium.
Ngokutsho kweMagnesium.com, ngo-1992, i-China yavelisa i-7 388 iitoni ze-magnesium. Ngo-2010, eli nani liqikelelwa yi-United States Geological Survey (USGS) ibe ngama-654,000 amathani okanye ngaphezulu kwe-85% yemveliso yomhlaba wonke.
Amazwe amaninzi ngaphandle kweChina ayenokuvelisa i-magnesium, kuquka uRashiya, uSirayeli, uKazakhstan kunye neChanada. Nangona kunjalo, ngokwemibare ye-USGS, umveliso wonyaka kulowo mazwe ungaphantsi kweetoni ezingama-40 000.
