Kuri iki cyumweru (7.4-7.8, kimwe kimwe hepfo), ibicuruzwa byisi byoroheje nubucyo bidasanzwe ku isoko ridasanzwe ryisi byerekanaga ko byagabanutse, kandi igabanuka ryubutaka bwumucyo budasanzwe bwihuse.Birashoboka ko ubukungu bukomeye mu Burayi no muri Amerika bugabanuka mu bukungu mu gice cya kabiri cy'umwaka biragaragara, kandi ibicuruzwa byoherezwa mu mahanga bigaragara ko byagaragaje ibimenyetso byo kugabanuka.Nubwo isoko yo hejuru nayo yagabanutse, ugereranije no kugabanuka kwicyifuzo, birasa nkaho hakiri ibisagutse.Muri rusange ibyihebe byo hejuru byiyongereye muri iki cyumweru, kandi isi yoroheje n’umucyo bidasanzwe byaguye mu buryo bugaragara bwo gupiganira amasoko.
Kuri iki cyumweru, ibicuruzwa bya praseodymium na neodymium byakomeje kugabanuka kumyumweru ishize.Hamwe n’ikurwaho ryingufu zinyuranye, ibyifuzo nibitekerezo bidakomeye, biterwa nigitutu cyamasoko, umuvuduko wo kugabanuka kumanuka wibigo byimbere byihuta cyane.Igikorwa cyisoko ni umuguzi, kandi igiciro cyigicuruzwa cyageze hasi cyane kubera ingaruka zo mumitekerereze ya "kugura ariko ntugure".
Bitewe na praseodymium na neodymium, ibyifuzo byibindi bicuruzwa bidasanzwe byisi bidasanzwe nabyo birakonje, kandi ibicuruzwa bya gadolinium byagabanutseho gato.Icyakora, kubera igabanuka ryoroheje ryibiciro by’ibirombe bidasanzwe by’ubutaka, ibicuruzwa bya dysprosium byahagaze neza mu mpera zicyumweru gishize, kandi byagabanutseho gato icyarimwe bitewe n’ingaruka z’imyumvire rusange.Dysprosium oxyde yagabanutseho 8.3% kuva muri Mata.Ibinyuranye, agaciro gakomeye k’ibicuruzwa bya terbium byagumishijwe mu gihe cy’umwaka, kandi imikoreshereze y’impande zose mu rwego rw’inganda yagabanutse kubera gutinya ibiciro biri hejuru no gushidikanya.Ariko, ugereranije, icyifuzo cya terbium mubihe byashize cyateye imbere ugereranije nigihe cyashize.Ubwinshi bw'imizigo ku isoko ni nto kandi muri rusange hari ibiciro biri hejuru, bityo kumva amakuru ku isoko ni bike.Kuri terbium ku giciro kiriho, nibyiza kuvuga ko iyobowe nubunini bwuzuye aho kongera umwanya wimikorere nigihe cyo kugabanuka, Ibi byongereye umuvuduko wo guhagarika igiciro cya terbium, bityo urwego rwo kwihagararaho rwa inganda zitwara imizigo ziri hasi cyane ugereranije na dysprosium.
Urebye kuri macro ubungubu, amadolari ya Amerika yaravunitse arazamuka.Amakuru amwe yavuze ko kwari ukugabanya ihungabana ryegereje muri Amerika, guverinoma y’Amerika yari iteganijwe kugabanya imisoro ku Bushinwa, kandi icyorezo mu bice byinshi by’isi kirwanya.Byongeye kandi, icyorezo mu bice bitandukanye by'igihugu cyaragarutsweho, bityo muri rusange umwuka mubi wari wihebye.Ukurikije ibyingenzi bigezweho, igabanuka ryihuse ryibiciro byisi bidasanzwe byateje igitutu kumasoko yo hasi.Kugeza ubu, ibipimo by'isi bidasanzwe mu gihugu ntibiteganijwe kwiyongera.Ibigo byinshi bitanga umusaruro murugo bizuzuza byimazeyo ibipimo byinshi muri uyu mwaka.Amabwiriza maremare yishyirahamwe yemeza ibyifuzo bimwe byo hasi, kandi umubare muto wibisabwa urashobora gutuma habaho gupiganira amasoko menshi.
