1. I-Aluminum Yezimayini Nokuncibilikisa: Ukusuka Ensimbini Kuya Ensimbini
Ukukhiqizwa kwe-aluminium kuqala ngokumba insimbi yayo eyinhloko, i-bauxite. I-Bauxite, egcwele emhlabeni wonke, ingena inqubo yokukhipha amakhemikhali eyinkimbinkimbi ukuze ikhiqize i-alumina, ebese incibilikiswa ukuze kukhiqizwe insimbi ye-aluminium ngokunciphisa i-electrolytic. Le nqubo idinga amandla kakhulu futhi ikhiqiza ukukhishwa kwekhabhoni, okwenza ukukhiqizwa kwe-aluminium kube nzima ngokwemithombo yezemvelo namandla.
Phakathi kwabakhiqizi be-aluminium abahamba phambili emhlabeni,Rio Tintofuthi u-Alcoa ugqamile. I-Rio Tinto, ikomkhulu layo e-UK nase-Australia, ingenye yezinkampani ezinkulu zezimayini emhlabeni jikelele futhi iphayona ekukhiqizeni i-aluminium enekhabhoni ephansi. I-Alcoa, esekelwe e-US, ibe ngumholi emizamweni emisha ye-aluminium kanye nokusimama, ngokuvamile isebenzisa imithombo yamandla avuselelekayo ezinkambisweni zayo zokukhiqiza. Zombili izinkampani zidlala indima ebalulekile ekuqinisekiseni ukuhlinzekwa komhlaba wonke kwe-aluminium yekhwalithi ephezulu, ezuzisa izimboni ezifana nokukhiqiza amakesi e-aluminium.
Ngokukhulayo, abakhiqizi be-aluminium bagxile ekukhiqizeni i-aluminium eluhlaza ngokusebenzisa amandla avuselelekayo ukunciphisa ukukhishwa kwekhabhoni. I-Aluminium iphinde igaywe kabusha kakhulu, i-aluminium egaywe kabusha isebenzisa cishe u-5% wamandla adingekayo ekukhiqizeni okuyinhloko. Lo mkhuba obheke ku-aluminiyamu egaywe kabusha uyadlondlobala embonini, obonisa intuthuko enhle kubathengi abakhathalela imvelo.
2. Ukucutshungulwa kwe-Aluminium: Ukubumba Ifomu Eliyingqayizivele Le-Aluminium Nezakhiwo
Uma ama-ingots e-aluminium esekhiqiziwe, athunyelwa ezindaweni zokucutshungulwa ukuze aginqike, akhishwe, kanye nezinye izinqubo zokwelashwa, azilolonge abe amashidi, amakhoyili, noma amaphrofayili amasayizi ahlukahlukene kanye nokucaciswa kwawo. Ukusetshenziswa okuhlukile kwamakesi e-aluminium kudinga izinhlobo ezihlukene zezinto ze-aluminium: amakesi angasindi angase abeke phambili ukulawulwa kwesisindo, kuyilapho amakesi okuvikela angase asebenzise i-aluminium ewugqinsi ukuze kuqine ukuqina.
Amanye amaphrosesa aphezulu we-aluminium emhlabeni afakaI-Hydro, I-Chalco, futhiAmanoveli. I-Hydro, inkampani yaseNorway, ihlonishwa kakhulu ngokuzibophezela kwayo ezixazululweni ze-aluminium esimeme futhi igxile ekukhiqizeni i-aluminium yekhwalithi ephezulu yezinhlelo zokusebenza ezihlukahlukene. I-Chalco (i-China Aluminium Corporation) ingumkhiqizi omkhulu waseShayina owaziwa ngemisebenzi yayo enwetshiwe ye-aluminium, okuhlanganisa izimayini, ukucubungula, nokugaywa kabusha. U-Novelis, umholi ozinze e-US emikhiqizweni egoqiwe ye-aluminium, ugxile kakhulu ekugayweni kabusha, obambe iqhaza ekukhiqizeni okusimeme kwezinto ze-aluminium zekhwalithi ephezulu ezimbonini ezifana nezezimoto, zokupakisha, nezikhethekile, njengamakesi e-aluminium.
Ukwelashwa okungaphezulu nakho kubalulekile kulesi sigaba. I-Anodizing aluminium ayigcini nje ngokuthuthukisa ukumelana nokugqwala kodwa futhi ithuthukisa ukubukeka kwayo, inikeze imibala eminingi nezinketho ezicwebezelayo. Le mininingwane yokucubungula inomthelela oqondile kwikhwalithi yokugcina kanye nempilo yamakesi e-aluminium.
3. Ukuthi Ikhwalithi Ye-Aluminium Nezindleko Kuyithinta Kanjani Intengo Yekesi
Njengabathengi, ukuqonda ukukhiqizwa nokucutshungulwa kwe-aluminium kusisiza ukuthi sazise kangcono ukwakheka kwezindleko zamakesi e-aluminium, futhi kusenza sikwazi ukwenza izinqumo ezinolwazi lapho sithenga. Isibonelo, ukukhetha amabhrendi asebenzisa i-aluminium egaywe kabusha eqinisekisiwe noma izinto zekhwalithi ephezulu akuqinisekisi kuphela umkhiqizo osezingeni eliphezulu kodwa futhi kusekela ukukhiqizwa okuhambisana nemvelo.
Esimisweni sezindleko zamacala e-aluminium, izinto ze-aluminium zimelela ingxenye enkulu. Ukushintshashintsha kwezintengo ze-aluminium kuthinta ngokuqondile intengo yemakethe yamakesi e-aluminium. Isibonelo, izintengo ze-aluminium zomhlaba zingakhuphuka kakhulu ngenxa yezinguquko zesidingo sokuhlinzekwa noma ukushintsha kwentengo yamandla, okunomthelela ikakhulukazi kubakhiqizi bamacala abathembele ku-aluminium yekhwalithi ephezulu. Lokhu kuguquguquka kwentengo ekugcineni kuba nomthelela kubathengi.
4. Amathrendi Esikhathi esizayo: Okuluhlaza, Kalula
Njengabathengi, ukuqonda ukukhiqizwa nokucutshungulwa kwe-aluminium kusisiza ukuthi sazise kangcono ukwakheka kwezindleko zamakesi e-aluminium, futhi kusenza sikwazi ukwenza izinqumo ezinolwazi lapho sithenga. Isibonelo, ukukhetha amabhrendi asebenzisa i-aluminium egaywe kabusha eqinisekisiwe noma izinto zekhwalithi ephezulu akuqinisekisi kuphela umkhiqizo osezingeni eliphezulu kodwa futhi kusekela ukukhiqizwa okuhambisana nemvelo.
Esimisweni sezindleko zamacala e-aluminium, izinto ze-aluminium zimelela ingxenye enkulu. Ukushintshashintsha kwezintengo ze-aluminium kuthinta ngokuqondile intengo yemakethe yamakesi e-aluminium. Isibonelo, izintengo ze-aluminium zomhlaba zingakhuphuka kakhulu ngenxa yezinguquko zesidingo sokuhlinzekwa noma ukushintsha kwentengo yamandla, okunomthelela ikakhulukazi kubakhiqizi bamacala abathembele ku-aluminium yekhwalithi ephezulu. Lokhu kuguquguquka kwentengo ekugcineni kuba nomthelela kubathengi.
