Ulwazi oluyisisekelo:
Imakethe ye-alumina inomkhuba olawulwa amanani ngo-2020, futhi ukukhiqizwa nokusetshenziswa kwe-alumina kugcine ibhalansi enkulu.Ezinyangeni ezimbalwa zokuqala zika-2021, ngenxa yokwehliswa kwenzalo yokuthengwa kwezincibilikisi ze-aluminium, izintengo ze-alumina zibonise ukuthambekela okubukhali kokwehla, kodwa kamuva zaphinde zaphindeka futhi ngokubuya kwemakethe.
Kusukela ngoJanuwari kuya ku-Okthoba 2020, ukukhiqizwa kwe-alumina yomhlaba wonke bekungamathani ayizigidi eziyi-110.466, okuwukukhuphuka kancane ngo-0.55% ngaphezu kwamathani ayizigidi eziyi-109.866 ngesikhathi esifanayo ngonyaka odlule.Umphumela we-alumina yebanga le-metallurgical ungamathani ayizigidi eziyi-104.068.
Ezinyangeni zokuqala eziyi-10, ukukhiqizwa kwe-alumina yaseChina kwehle ngo-2.78% unyaka nonyaka kuya kumathani ayizigidi ezingama-50.032.Ngaphandle kweShayina, ukukhiqizwa kwanda e-Afrika nase-Asia (ngaphandle kwe-China), eMpumalanga namaphakathi neYurophu naseNingizimu Melika.E-Afrika nase-Asia (ngaphandle kwe-China), ukukhiqizwa kwe-alumina kwaba amathani ayizigidi ezingu-10.251, okuwukukhuphuka ngo-19.63% ngaphezu kwamathani ayizigidi ezingu-8.569 ngesikhathi esifanayo ngonyaka odlule.Umphumela wamazwe asempumalanga nemaphakathi neYurophu ube ngamathani ayizigidi ezi-3.779, okuwukukhula ngo-2.91% uma kuqhathaniswa namathani ayizigidi ezi-3.672 angonyaka odlule;Umphumela waseNingizimu Melika wawungamathani ayizigidi ezingu-9.664, u-10.62% ngaphezu kwamathani ayizigidi ezingu-8.736 ngonyaka odlule.I-Oceania ingumkhiqizi wesibili omkhulu we-alumina ngemuva kweChina.Kusukela ngoJanuwari kuya ku-Okthoba 2020, ukukhiqizwa kwe-alumina kulesi sifunda bekungamathani ayizigidi eziyi-17.516, uma kuqhathaniswa namathani ayizigidi eziyi-16.97 ngonyaka odlule.
Ukunikezwa kanye nesidingo:
I-Alcoa ikhiqize amathani ayizigidi ezi-3.435 e-alumina engxenyeni yesithathu ka-2020 (kusukela ngoSepthemba 30), okuwukunyuka ngo-1.9% ngaphezu kwamathani ayizigidi ezi-3.371 ngesikhathi esifanayo ngonyaka odlule.Ukuthunyelwa kwezinkampani zangaphandle engxenyeni yesithathu nakho kukhuphuke kwafinyelela kumathani ayizigidi ezingu-2.549 kusukela kumathani ayizigidi ezingu-2.415 ngekota yesibili.Inkampani ilindele ukuthi ngenxa yokuthuthukiswa kwezinga lokukhiqiza, ithemba layo lokuthunyelwa kwe-alumina ngo-2020 lizokhuphuka ngamathani angu-200000 liye kumathani ayizigidi ezingu-13.8 - 13.9.
NgoJulayi 2020, i-aluminium yomhlaba wonke ye-UAE yazuza umthamo we-nameplate wamathani ayizigidi ezi-2 we-alumina phakathi nezinyanga eziyi-14 ngemuva kokuthi indawo yayo yokuhluza i-al taweelah alumina iqale ukusebenza.Lo mthamo wanele ukuhlangabezana no-40% wesidingo se-alumina ye-EGA futhi umiselele eminye imikhiqizo engenisiwe.
Embikweni wayo wokusebenza wekota yesithathu, i-hydro ithe indawo yayo yokuhluza i-alunorte alumina inyusa ukukhiqizwa ngendlela ebekiwe.Ngo-Agasti 18, i-hydro yamisa ukusebenza kwepayipi elithutha i-bauxite lisuka kuma-paragomina liya e-alunorte ukuze lilungiswe kusenesikhathi, lishintshe amanye amapayipi, limise okwesikhashana ukukhiqizwa kwama-paragomina futhi linciphise ukukhiqizwa kwe-alunorte libe ngu-50% wawo wonke umthamo.Ngomhla ziyisi-8 kuMfumfu, ama-paragomina aqala kabusha ukukhiqiza, futhi i-alunorte yaqala ukukhuphula umkhiqizo waba amathani ayizigidi ezingu-6.3 womthamo we-nameplate.
Ukukhiqizwa kwe-alumina yase-Rio Tinto kulindeleke ukuthi kwenyuke kusuka kumathani ayizigidi ezingu-7.7 ngo-2019 kuya kumathani ayizigidi ezingu-7.8 kuya kwezingu-8.2 ngo-2020. Le nkampani yatshala ama-US $51 wezigidi ukuze kuthuthukiswe izisetshenziswa zemboni yayo yokuhluza i-alumina i-Vaudreuil eQuebec, eCanada.Kubikwa ukuthi kusakhiwa izakhiwo ezintathu ezintsha ezonga ugesi.
Ngakolunye uhlangothi, uhulumeni wase-Andhra Pradesh, e-India uvumela i-anrak Aluminium Co., Ltd. ukuthi iphathise indawo yayo yokuhluza i-rachapalli alumina etholakala eVisakhapatnam makavarapalem.
UJoyce Li, umhlaziyi omkhulu we-SMM, uphawule ukuthi ngo-2020, kungase kube negebe lokuhlinzekwa kwamathani angama-361000 emakethe ye-alumina yaseChina, futhi isilinganiso sonyaka sokusebenza kwesitshalo se-aluminium oxide singama-78.03%.Kusukela ekuqaleni kukaZibandlela, amathani ayizigidi ezingama-68.65 wokukhiqiza i-alumina ayesesebenza phakathi kwamandla okukhiqiza akhona angamathani ayizigidi ezingama-88.4 ngonyaka.
Ukugxila kwezohwebo:
Ngokwedatha ekhishwe uMnyango Wezomnotho wase-Brazil ngoJulayi, ukuthunyelwa kwe-alumina yase-Brazil kukhuphuke ngoJuni, nakuba izinga lokukhula lehlile uma liqhathaniswa nenyanga edlule.Kusukela ngoMeyi 2020, ukuthunyelwa kwe-alumina yaseBrazil kukhuphuke okungenani ngama-30% ngenyanga.
Kusukela ngoJanuwari kuya ku-Okthoba 2020, iChina yangenisa amathani ayizigidi ezi-3.15 e-alumina, okuwukunyuka konyaka ngama-205.15%.Kulinganiselwa ukuthi ekupheleni kuka-2020, ukuthengwa kwe-alumina yaseChina kulindeleke ukuthi kuzinze kumathani ayizigidi ezingu-3.93.
Amathemba esikhathi esifushane:
UJoyce Li, umhlaziyi ophezulu kwa-SMM, ubikezela ukuthi u-2021 uzoba umvuthwandaba wokukhiqiza i-alumina yaseChina, kuyilapho ukuhlinzeka ngokweqile phesheya kuzokhula futhi ingcindezi izokhula.
