Ulwazi olusisiseko:
Imakethi ye-alumina inomgangatho olawulwayo wexabiso ngo-2020, kwaye ukuveliswa kunye nokusetyenziswa kwe-alumina kugcine ibhalansi enkulu.Kwiinyanga ezimbalwa zokuqala zika-2021, ngenxa yokwehliswa kwenzala yokuthengwa kwezinyibilikisi ze-aluminiyam, amaxabiso e-alumina abonise ukuhla okubukhali, kodwa kamva aphinde aphinda abuyele kwimarike.
Ukusukela ngoJanuwari ukuya ku-Okthobha ka-2020, imveliso ye-alumina yehlabathi ibe yi-110.466 yezigidi zeetoni, ukunyuka okuncinci kwe-0.55% ngaphezulu kwe-109.866 yezigidi zeetoni ngexesha elifanayo kulo nyaka uphelileyo.Imveliso ye-alumina ye-metallurgical grade yi-104.068 yezigidi zeetoni.
Kwiinyanga ezili-10 zokuqala, imveliso ye-alumina yaseChina yehle nge-2.78% ngonyaka ukuya kwi-50.032 yezigidi zeetoni.Ngaphandle kwe-China, imveliso yanda e-Afrika nase-Asia (ngaphandle kwe-China), iMpuma kunye neYurophu ephakathi kunye ne-South America.E-Afrika nase-Asia (ngaphandle kwe-China), imveliso ye-alumina yayiyi-10.251 yezigidi zeetoni, ukwanda kwe-19.63% ngaphezu kwe-8.569 yezigidi zeetoni ngexesha elifanayo kunyaka odlulileyo.Imveliso yeMpuma nombindi weYurophu ibezizigidi ezi-3.779 zeetoni, ukwanda nge-2.91% kunonyaka ophelileyo kwiitoni ezizizigidi ezi-3.672;Imveliso yaseMzantsi Melika yayiyi-9.664 yezigidi zeetoni, i-10.62% ephezulu kune-8.736 yezigidi zeetoni kunyaka ophelileyo.UOceania ngowesibini ngobukhulu umvelisi wealumina emva kweTshayina.Ukususela ngoJanuwari ukuya ku-Okthobha ka-2020, imveliso ye-alumina kulo mmandla yayiziitoni ezizigidi ezili-17.516, xa kuthelekiswa ne-16.97 yezigidi zeetoni kunyaka ophelileyo.
Unikezo nemfuno :
I-Alcoa ivelise i-3.435 yezigidi zeetoni ze-alumina kwikota yesithathu ye-2020 (ukusukela nge-30 Septemba), ukwanda kwe-1.9% ngaphezu kweetoni ze-3.371 yezigidi ngexesha elifanayo kunyaka odlulileyo.Ukuthunyelwa kweqela lesithathu kwikota yesithathu nako kunyuke ukuya kutsho kwi-2.549 yezigidi zeetoni ukusuka kwi-2.415 yezigidi zeetoni kwikota yesibini.Inkampani ilindele ukuba ngenxa yokuphucula umgangatho wemveliso, ithemba layo lokuthunyelwa kwe-alumina ngo-2020 liya kunyuka ngeetoni ze-200000 ukuya kwi-13.8 - 13.9 yezigidi zeetoni.
NgoJulayi ka-2020, i-aluminiyam yehlabathi ye-UAE ifumene umthamo we-nameplate we-2 yezigidi zeetoni ze-alumina kwisithuba seenyanga ezili-14 emva kokuba i-al taweelah alumina yokucokisa iqalile ukusebenza.Lo mthamo wanele ukuhlangabezana ne-40% yemfuno ye-alumina ye-EGA kunye nokubuyisela ezinye iimveliso ezivela kumazwe angaphandle.
Kwingxelo yayo yokusebenza kwikota yesithathu, i-hydro yathi indawo yokucoca i-alunorte alumina yayinyusa imveliso ukuya kwinqanaba elichaziweyo.Ngomhla we-18 ka-Agasti, i-hydro yamisa ukusebenza kombhobho ohambisa i-bauxite ukusuka kwi-paragominas ukuya kwi-alunorte ukwenzela ukulungisa kwangaphambili, ukubuyisela ezinye iipayipi, ukumisa okwethutyana ukuveliswa kwe-paragominas kunye nokunciphisa imveliso ye-alunorte ukuya kwi-50% yomthamo opheleleyo.Ngomhla we-8 ka-Okthobha, i-paragominas iphinde yaqala ukuvelisa, kwaye i-alunorte yaqala ukwandisa imveliso ukuya kwi-6.3 yezigidi zeetoni ze-nameplate umthamo.
Imveliso ye-alumina yaseRio Tinto kulindeleke ukuba inyuke ukusuka kwi-7.7 yezigidi zeetoni ngo-2019 ukuya kwi-7.8 ukuya kwi-8.2 yezigidi zeetoni ngo-2020. Le nkampani ityale i-US $ 51 yezigidi ukuze kuphuculwe izixhobo zokucoca i-alumina yeVaudreuil eQuebec, eCanada.Kuxelwe ukuba kusakhiwa izakhiwo ezitsha ezintathu ezonga umbane.
Kwelinye icala, urhulumente waseAndhra Pradesh, eIndiya uvumela i-anrak Aluminium Co., Ltd. ukuba iphathise indawo yokucoca i-rachapalli alumina eseVisakhapatnam makavarapalem.
UJoyce Li, umhlalutyi ophezulu we-SMM, uphawule ukuba ngo-2020, kunokubakho umsantsa wokubonelela ngeetoni ze-361000 kwimarike ye-alumina yaseChina, kwaye umyinge wonyaka wokusebenza kwesityalo se-aluminium oxide yi-78.03%.Ukususela ekuqaleni kukaDisemba, i-68.65 yezigidi zeetoni zomthamo wokuvelisa i-alumina yayisebenza phakathi komthamo okhoyo wemveliso we-88.4 yezigidi zeetoni ngonyaka.
Ujoliso kurhwebo:
Ngokutsho kwedatha ekhutshwe nguMphathiswa wezoQoqosho waseBrazil ngoJulayi, ukuthunyelwa kwe-alumina yaseBrazil kuye kwanda ngoJuni, nangona izinga lokukhula liyehla xa kuthelekiswa nenyanga edlulileyo.Ukusukela ngoMeyi ka-2020, ukuthunyelwa kwe-alumina eBrazil kuye kwanyuka ubuncinane nge-30% inyanga ngenyanga.
Ukususela ngoJanuwari ukuya ku-Okthobha ka-2020, i-China ingenise i-3.15 yezigidi zeetoni ze-alumina, ukunyuka konyaka-ngonyaka kwe-205.15%.Kuqikelelwa ukuba ekupheleni kuka-2020, ukungenisa kwe-alumina yaseChina kulindeleke ukuba kuzinze kwi-3.93 yezigidi zeetoni.
Amathemba exesha elifutshane:
UJoyce Li, umhlalutyi ophezulu kwi-SMM, uqikelela ukuba i-2021 iya kuba yincopho yemveliso ye-alumina yaseChina, ngelixa i-oversupply oversupply iya kuqinisa kwaye uxinzelelo luya kwanda.
