(I-ICSG) ibike ngoSepthemba 23 ukuthi umkhiqizo wethusi ocwengisisiwe emhlabeni wonke kusukela ngoJanuwari kuya kuJuni ukhuphuke ngo-3.2% unyaka nonyaka, umkhiqizo wethusi ocwengisisiwe (kufaka phakathi i-electrolysis kanye nokuwina i-electro) uphakeme ngo-3.5% kunowonyaka ofanayo, kanti umkhiqizo wethusi ovuselelwe okhiqizwe ngethusi elilahliwe uphakeme ngo-1.7% kunowonyaka ofanayo. Ukukhiqizwa kwethusi elicwengisisiwe eShayina kukhuphuke ngamaphesenti ayi-6 esikhathini sikaJanuwari-Juni kusukela ngonyaka odlule, ngokusho kwezibalo ezisemthethweni zokuqala. Umkhiqizo wethusi ocwengisisiwe eChile wawuphansi ngo-7% kunesikhathi esifanayo ngonyaka odlule, kanti ithusi elicwengisisiwe le-electrolytic likhuphuke ngo-0.5%, kodwa ithusi elicwengisisiwe lehle ngo-11%. E-Afrika, ukukhiqizwa kwethusi elicwengisisiwe eDemocratic Republic of the Congo kukhuphuke ngamaphesenti ayi-13.5 unyaka nonyaka njengoba kuvulwa izimayini ezintsha zethusi noma izitshalo ze-hydrometallurgical zanda. Ukukhiqizwa kwethusi elicwengisiwe eZambia kukhuphuke ngamaphesenti ayi-12 njengoba abancibilikisi belulama ekuvalekeni kokukhiqiza nasezinkingeni zokusebenza ngo-2019 nasekuqaleni kuka-2020. Ukukhiqizwa kwethusi elicwengisiwe lase-US kukhuphuke ngamaphesenti ayi-14 unyaka nonyaka njengoba abancibilikisi belulama ezinkingeni zokusebenza ngo-2020. Imininingwane yokuqala ibonise ukwehla kokukhiqiza eBrazil, eJalimane, eJapan, eRussia, eSpain (SX-EW) naseSweden ngezizathu ezahlukahlukene, okuhlanganisa ukuvalwa kokulungiswa, izinkinga zokusebenza kanye nokuvalwa kwezitshalo ze-SX-EW.
