[Kugawana zaukadaulo] Kutulutsa kwa scandium oxide posakaniza matope ofiira ndi titanium dioxide waste acid

Matope ofiira ndi tinthu tating'onoting'ono tamphamvu zamchere zolimba zomwe zimapangidwa popanga alumina ndi bauxite ngati zopangira. Pa toni iliyonse ya aluminiyamu yopangidwa, pafupifupi matani 0,8 mpaka 1.5 amatope ofiira amapangidwa. Kusungidwa kwakukulu kwa matope ofiira sikumangotenga nthaka ndi kuwononga chuma, komanso kumayambitsa kuwonongeka kwa chilengedwe ndi ngozi mosavuta.Titaniyamu dioxideZinyalala zamadzimadzi ndi hydrolysis zinyalala madzi opangidwa pamene titaniyamu woipa amapangidwa ndi njira sulfuric acid. Pa tani iliyonse ya titaniyamu woipa wopangidwa, matani 8 mpaka 10 a zinyalala za asidi okhala ndi 20% ndi 50 mpaka 80 m3 yamadzi onyansa okhala ndi 2% amapangidwa. Lili ndi zinthu zambiri zamtengo wapatali monga titaniyamu, aluminiyamu, chitsulo, scandium, ndi sulfuric acid. Kutulutsa kwachindunji sikumangowononga kwambiri chilengedwe, komanso kumabweretsa kuwonongeka kwakukulu kwachuma.

Matope ofiira ndi zinyalala zolimba zamchere, ndipo titaniyamu wotayirira zinyalala zamadzimadzi ndi acidic madzi. Pambuyo pakuchepetsa asidi ndi zamchere mwa ziwirizi, zinthu zamtengo wapatali zimasinthidwanso ndikugwiritsiridwa ntchito, zomwe sizingangopulumutsa ndalama zopangira, komanso kupititsa patsogolo kuchuluka kwa zinthu zamtengo wapatali muzinthu zotayirira kapena zakumwa zotayira, ndipo zimathandizira kuchira kotsatira. ndondomeko. Kubwezeretsanso ndikugwiritsanso ntchito zinyalala ziwirizi zili ndi tanthauzo la mafakitale, ndiscandium oxideali ndi mtengo wapatali komanso ubwino wachuma.
Ntchito yochotsa scandium oxide kuchokera kumatope ofiira ndi titaniyamu wotayidwa wamadzimadzi ndi yofunika kwambiri kuthetsa kuipitsidwa kwa chilengedwe ndi zoopsa zachitetezo zomwe zimadza chifukwa cha kusungirako matope ofiira ndi kutaya kwa titanium dioxide. Ndichinthu chofunikira kwambiri pakukhazikitsa lingaliro lachitukuko cha sayansi, kusintha njira yachitukuko chachuma, kukhazikitsa chuma chozungulira, ndikumanga anthu opulumutsa zinthu komanso okonda zachilengedwe, komanso kukhala ndi mapindu abwino.
