Nyuma yimyaka irenga 40 yimbaraga, cyane cyane iterambere ryihuse kuva 1978, Ubushinwaisi idasanzweinganda zagiye zisimbuka neza mu rwego rw’umusaruro n’ubuziranenge bw’ibicuruzwa, bikora sisitemu yuzuye y’inganda.Kugeza ubu,isi idasanzwegutunganya mu Bushinwa
Ubushobozi bwo gushonga no gutandukanya amabuye bugera kuri toni zisaga 130000 ku mwaka (REO), kandi umusaruro w’ubutaka budasanzwe buri mwaka ugera kuri toni zirenga 70000, bingana na 80% by’umusaruro rusange ku isi.Umusaruro n’ibicuruzwa byoherezwa mu mahanga byombi binini ku isi.
Hariho abarenga 170isi idasanzweinganda zo gushonga no gutandukanya mu Bushinwa, ariko 5 gusa ni zo zifite ubushobozi bwo gutunganya buri mwaka zirenga toni 5000 (REO), hamwe n’ibigo byinshi bifite ubushobozi bwo gutunganya toni 1000-2000.
Kugeza ubu, Ubushinwa bwashinze ibirindiro bitatu by’ibicuruzwa ahanini bigera kuri bitatu byingenziisi idasanzweibikoresho:
(1) Amajyaruguruisi idasanzweishingiro ry'umusaruro ryashizweho hamwe na Baotou ivanzeisi idasanzweubutare nkibikoresho fatizo, hamwe na BaotouNtibisanzwe IsiHigh Tech na Gansu Rare Earth Company nkumugongo.Hariho imishinga irenga 80 itanga umusaruroisi idasanzweimiti nkaisi idasanzwe ya chloridena karubone buri mwaka
Toni zirenga 60000 zivanze hamwe na toni 15000 imwe imweisi idasanzweibice.Kugeza ubu, benshiisi idasanzweinganda zitunganya ubutare bwa Baotou zikoresha uburyo bwo gushonga aside yatunganijwe na Beijing Nonferrous Metals Research Institute, hanyuma ukoreshe P204 cyangwa P507 yo gukuramo sgutandukana, muri byocerium-yera cyanemuri rusange ikururwa no gukuramo okiside, hamwe na fluorescent urwegoeuropium oxydeikururwa no kugabanya gukuramo.Ibicuruzwa byingenzi birimo ibice bimwe cyangwa bivanze bidasanzwe byisi nkalanthanum, cerium, praseodymium, neodymium, samarium, europium, n'ibindi.
(2) Hagati kandi iremereyeisi idasanzweumusaruro fatizo ufata amabuye yubwoko bwa ionic yepfo nkibikoresho fatizo, kandi ikora toni zigera kuri 20000 zubwoko bwa ionic yepfoisi idasanzweamabuye y'agaciro buri mwaka.Ibigo by'umugongo birimo Guanzhou Pearl River Smelter, Jianyin JiahuaNtibisanzwe IsiUruganda, na Yixin Xinwei Rare Earth Co, Ltd, Liyan Luodiya Fangzheng Rare Earth Company, Uruganda rwa Guangdong Yanjiang Rare Earth, nibindi. gukuramo aside no kweza.
Hagati kugeza kuremereyeisi idasanzwehamwe nibintu bimwe bikungahaye nkayttrium, dysprosium, terbium, europium, lanthanum, neodymium, samarium, n'ibindi.
.Kugeza ubu hari ibimera 27 bya hydrometallurgie bifite umusaruro wa toni 15-2000.Uburyo bwo gushonga ubutare bwa fluor naceriumubutare burimo cyane cyane okiside ikaranze vuburyo bukomeye bwo kuvura imiti ikomoka kubikorwa byingenzi byo gutwika aside sulfurike, hamwe nibicuruzwa ari kimwe cyangwa bivanze nubutaka budasanzwe bugizwe ahaninilanthanum, cerium, naneodymium.Ibigo byinshi ni bito mubipimo, bifite ibikoresho bike nurwego rwikoranabuhanga.Thano hari ibicuruzwa byinshi byibanze muriisi idasanzwegushonga ibicuruzwa, hamwe nubuziranenge bwinshi hamwe nibicuruzwa bidasanzwe bivangwa nubutaka bivugwa ko bitarenze 5%.
