Sharaxaad Gaaban

Bauxite waa macdano dabiici ah, aad u adag waxayna ugu horrayn ka kooban tahay xeryahooda aluminium oxide (alumina), silica, oksaydhka birta iyo titanium dioxide. Qiyaastii 70 boqolkiiba wax soo saarka bauxite ee aduunka waxaa lagu sifeeyaa habka kiimikaad ee Bayer oo la geliyo aluminium.

Iyada oo ku saleysan xaqiiqda ah in bauxite clinker uu leeyahay kulayl yar yar iyo iska caabin ka fiican oo iska caabin ah iyo hantida iska caabbinta, waxaa loo isticmaali karaa HFST (daawaynta dusha sare ee jilicsanaanta) ama lakabka nabarka ee isku dhafka asphalt si loogu beddelo ama qayb ahaan loo beddelo wadarta hadda jirta. Bauxite clinker waxaa loo kala saaraa inta badan lix nooc iyadoo loo eegayo waxyaabaha ka kooban kiimikada kala duwan. Doorashada bauxite clinker sida wadar ahaan ma aha oo kaliya qiimaha dhaqaalaha, laakiin sidoo kale hagaajinta adhesion u dhexeeya wadarta iyo asphalt, kaas oo leh indho la'aan gaar ah. Daraasadani waxay qiimeysay sifooyinka noocyada kala duwan ee clinker bauxite. bauxite clinker oo leh asphalt ayaa lagu qiimeeyay habka kicinta ee habka adsorption hydrostatic iyo aragtida tamarta bilaashka ah ee dusha sare.

Faahfaahinta xogta

Bauxite waa alaabta ceeriin ee ugu fiican ee wax soo saarka aluminium. Marka laga reebo walxaha aasaasiga ah ee aluminium iyo silikoon, bauxite waxaa inta badan lagu lamaaniyaa waxyaabo badan oo qiimo leh sida gallium (Ga), titanium (Ti), scandium (Sc), iyo lithium (Li). wax soo saarka sida caadiga ah waxaa ku jira xaddi la taaban karo oo walxo qiimo leh, taas oo ka dhigaysa isha suurtagalka ah ee polymetallic. Soo kabashada qaybahan muhiimka ah waxay si weyn u kordhin kartaa hufnaanta habka wax soo saarka aluminium iyadoo la dhimayo mas'uuliyadda warshadaha iyo saameynta deegaanka. Daraasadani waxay bixinaysaa falanqayn muhiim ah oo ku saabsan tignoolajiyada jira ee loo isticmaalo ka soo kabashada walxaha qiimaha leh ee haraaga bauxite iyo wareejinta khamriga la isticmaalay si ay u bixiso aragti ku saabsan isticmaalka balaadhan ee haraaga bauxite kheyr ahaan halkii ay ahaan lahayd qashinka. Isbarbardhigga sifooyinka hab-socodka jira ayaa muujinaya in habka isku dhafan ee soo kabashada walxaha qiimaha leh iyo yaraynta qashinka ay faa'iido leedahay.
