dhoobo cas waa haraaga wasakhda wasakhda warshadaha oo ay soo saarto bauxite habka soo saarista aluminium. Waa casaan, casaan madow ama dhoobo cawlan oo kale sababtoo ah waxa ku jira oksaydhka birta ee kala duwan. Waxa ay leedahay biyo aad u badan waxa uuna ka kooban yahay waxyaabo waxyeelo leh sida alkali iyo biraha culus. noqo cudur daba-dheeraaday oo saameeya deegaanka deegaanka. Qaybaha ugu muhiimsan ee dhoobada cas waa SiO2, Al2O3, CaO, Fe2O3, iwm, waxaana ku jira xaddi badan oo kiimikooyin alkaline ah. Qiimaha pH wuxuu gaari karaa in ka badan 11, taas oo ah alkaline xooggan. Marka heerka sare ee bauxite ee dalkaygu uu sii yaraanayo, qadarka dhoobada cas ee laga soo saaro wax soo saarka 1 tan ee alumina waxay gaari kartaa 1.5-2 tan.
Sida laga soo xigtay xogta laga soo xigtay Xafiiska Tirakoobka Qaranka, wax soo saarka aluminium ee Shiinaha ee 2021 wuxuu noqon doonaa 77.475 milyan oo tan, koror sanadle ah oo ah 5.0%. Haddii la xisaabiyo iyadoo lagu salaynayo sii daynta 1.5 tan oo dhoobo cas ah halkii ton oo alumina ah, sii daynta dhoobada cas ee 2021 oo keliya waxay noqon doontaa ilaa 100 milyan oo tan, iyo heerka isticmaalka guud ee dhoobada cas ee dalkaygu waa 7% oo keliya. . Ururinta dhoobada cas kaliya kuma koobna khayraadka dhulka hadii aan si fiican loo maamulin, waxa kale oo ay keenaysaa khataro ay ka mid yihiin biyo xidheenka oo fashilma oo ku yimaadda kaydka dhoobada cas, wasakhowga ciidda iyo biyaha iwm. Sidaa darteed, waxa degdeg ah in sare loo qaado ka faa’iidaysiga casaanka. dhoobo.
dhoobada cas ayaa inta badan ka kooban macdan kala duwan oo qiimo leh, oo ay ugu badan yihiin birta, aluminium, titanium, vanadium, iwm, kuwaas oo dib loo warshadeyn karo si loo helo kheyraad suurtagal ah. Qaybta tirada badan ee Fe2O3 ee habka Bayer dhoobada cas ayaa guud ahaan ka sarreysa 30%, taas oo ah qaybta ugu muhiimsan ee kiimikada dhoobada cas. Sanadihii la soo dhaafay, Shirkadda Huate waxay si joogto ah u samaynaysay cilmi-baaris iyo cilmi-baaris ku saabsan kala-soocidda dhoobada cas, waxayna soo saartay qalab dhamaystiran. ee tignoolajiyada kala soocida birta dhoobada cas iyo budada ganaaxa. , 40% ilaa 50% macdanta birta ah ee dhoobada cas waxaa lagu soo celin karaa iyada oo loo marayo magnetic daciif ah iyo laba habka faa'iido magnetic xoog leh, iyo codsiyada warshadaha baaxad weyn ayaa lagu fuliyay Shandong, Guangxi, Guizhou, Yunnan iyo gobollada kale. Tilmaamayaashu way fiican yihiin. Dib u soo kabashada biraha qiimaha leh ee dhoobada cas ma abuuri karto oo kaliya faa'iidooyin dhaqaale, laakiin sidoo kale waxay badbaadisaa kheyraadka waxayna yareysaa cadaadiska deegaanka.

"Qorshaha Hirgelinta ee Dardargelinta Horumarinta Ka Faa'iidaysiga Dhamaystiran ee Khayraadka Warshadaha" oo ay dhawaan soo saareen siddeed waaxood oo ay ku jiraan Wasaaradda Warshadaha iyo Tignoolajiyada iyo Wasaaradda Deegaanka iyo Deegaanka ayaa soo bandhigay shuruudo cadcad oo loogu talagalay heerka isticmaalka guud ee qashinka adag ee warshadaha inta lagu jiro. muddada "Qorshaha Shanta Sano ee 14aad". Si kastaba ha ahaatee, ka faa'iidaysiga dhamaystiran ee dhoobada cas, kaliya "horumar wax ku ool ah" ayaa loo baahan yahay. Sababtu waxa weeye alkalis kiimikaad ah oo lagu daray dhoobo guduudan way adag tahay in la saaro, waxa ku jirana waa badan yihiin, waxa kale oo ku jira fluorine, aluminium iyo wasakh kale. Isticmaalka dhoobada cas ee aan waxyeellada lahayn ayaa had iyo jeer ahaa mid adag in la fuliyo, markaa ka faa'iidaysiga dhamaystiran ee dhoobada cas ayaa weli ah dhibaato caalami ah. . U wac cutubyada cilmi-baarista cilmi-baarista ee khuseeya si ay u sii wadaan cilmi-baaris qoto-dheer oo lagu daray tignoolajiyada isticmaalka dhammaystiran ee dhoobada cas ee hadda jirta si loo kordhiyo ka faa'iidaysiga dhamaystiran ee ilaha dhoobada cas.
