2021 unyaka nonyaka, inhlangano yocwaningo lwethusi yamazwe ngamazwe (i-ICSG) yabika ngoSepthemba 23 ukuthi umkhiqizo wethusi ocolisisiwe emhlabeni kusukela ngoJanuwari kuya kuJuni ukhuphuke ngo-3.2% unyaka nonyaka, ukukhishwa kwethusi le-electrolytic (kuhlanganise ne-electrolysis kanye ne-electrowinning) kungu-3.5 Amaphesenti angaphezu kwalawo angonyaka ofanayo, futhi umphumela wekhopha evuselelwe kabusha ekhiqizwa emfucumfucwini wethusi ungaphezulu ngo-1.7% kunalowo nyaka ofanayo.Ukukhiqizwa kwethusi elicolisisiwe eChina kukhuphuke ngamaphesenti ayisi-6 esikhathini sikaJanuwari-Juni kusukela ngonyaka owedlule, ngokwezibalo ezisemthethweni.Ukukhishwa kwethusi elicolisisiwe eChile bekungaphansi ngo-7% kunesikhathi esifanayo ngonyaka odlule, ithusi elicwengiswa nge-electrolytic likhuphuke ngo-0.5%, kodwa i-electrorefining yethusi yehle ngo-11%.E-Afrika, ukukhiqizwa kwethusi elicolisisiwe e-Democratic Republic of the Congo kukhuphuke ngamaphesenti angu-13.5 unyaka nonyaka njengoba kuvulwa izimayini zethusi ezintsha noma izitshalo ze-hydrometallurgical zanda.Ukukhiqizwa kwethusi elicolisisiwe e-Zambia kukhuphuke ngamaphesenti angu-12 njengoba izincibilikisi zilulama ekuvaleni ukukhiqizwa kanye nezinkinga zokusebenza ngo-2019 nasekuqaleni kuka-2020. Ukukhiqizwa kwethusi elicolisisiwe lase-US kukhuphuke ngamaphesenti angu-14 unyaka nonyaka njengoba izincibilikisi zilulama ezinkingeni zokusebenza ngo-2020. Idatha yokuqala ibonise ukwehla kokukhiqiza eBrazil, eJalimane, eJapane, eRussia, eSpain (SX-EW) naseSweden ngenxa yezizathu ezihlukahlukene, okuhlanganisa ukuvalwa kokulungiswa, izinkinga zokusebenza nokuvalwa kwezitshalo ze-SX-EW.
