Sharaxaad Gaaban

Bauxite waa macdan dabiici ah oo aad u adag, waxaana inta badan ka kooban iskudhisyo aluminium oksaydh ah (alumina), silica, birta oksaydh iyo titanium dioxide. Qiyaastii boqolkiiba 70 wax soo saarka bauxite ee adduunka waxaa lagu sifeeyaa habka kiimikada ee bayer ilaa alumina.

Iyada oo lagu saleynayo xaqiiqda ah in bauxite clinker uu leeyahay koronto yar oo kuleyl ah iyo iska caabin wanaagsan oo simbiriirixan iyo sifooyin iska caabin ah oo xirashada ah, waxaa loo isticmaali karaa HFST (daaweynta dusha sare ee is jiidjiidka sare) ama lakabka xoqidda ee isku darka asfaltka si loogu beddelo ama qayb ahaan loogu beddelo wadarta guud ee jirta. Bauxite clinker waxaa loo kala saaraa inta badan lix nooc iyadoo loo eegayo waxyaabaha ku jira kiimikada kala duwan. Xulashada bauxite clinker sida isku-darka ma aha oo kaliya qiimaha dhaqaale, laakiin sidoo kale waa hagaajinta isku-xidhka u dhexeeya isku-darka iyo asfaltka, kaas oo leh indho la'aan gaar ah. Daraasaddani waxay qiimeysay astaamaha noocyada kala duwan ee bauxite clinker. Isku-xidhka noocyada kala duwan ee bauxite clinker oo leh asfalt waxaa lagu qiimeeyay habka nuugista hydrostatic ee kacsan iyo aragtida tamarta aan dusha sare lahayn. Saamaynta xuduudaha astaamaha ee bauxite clinker ee ku-xidhka waxaa lagu qiimeeyay falanqaynta entropy isku-xidhka cawlan.

Macluumaadka faahfaahinta

Bauxite waa walaxda ugu habboon ee ceeriin ee lagu sameeyo alumina. Marka laga reebo walxaha aasaasiga ah ee aluminiumka iyo siliconka, bauxite waxaa badanaa lala xiriiriyaa walxo badan oo qiimo leh sida gallium (Ga), titanium (Ti), scandium (Sc), iyo lithium (Li). Hadhaaga bauxite iyo khamriga ku jira wareegga ee wax soo saarka alumina waxay badanaa ku jiraan xaddi badan oo walxo qiimo leh, taasoo ka dhigaysa ilo suurtagal ah oo polymetallic ah. Soo kabashada qaybahan muhiimka ah waxay si weyn u kordhin kartaa hufnaanta habka wax soo saarka alumina iyadoo la dhimayo mas'uuliyadda warshadaha iyo saameynta deegaanka. Daraasaddani waxay bixinaysaa falanqayn muhiim ah oo ku saabsan tignoolajiyada jirta ee loo isticmaalo in lagu soo celiyo walxaha qiimaha leh ee ka soo hadha bauxite iyo khamriga ku jira wareegga si loo helo aragti ku saabsan isticmaalka ballaaran ee hadhaaga bauxite sidii kheyraad halkii laga ahaan lahaa qashin. Isbarbardhigga sifooyinka habka jira waxay muujinayaan in habka isku dhafan ee soo kabashada walxaha qiimaha leh iyo yaraynta qiiqa qashinka uu faa'iido leeyahay.
