Emva kweminyaka engaphezu kwama-40 yemizamo, ngakumbi lophuhliso olukhawulezileyo ukusukela ngo-1978, i-China'sumhlaba onqabileyoUmzi-mveliso wenziwe i-quatititity yenqanaba lemveliso kunye nomgangatho wemveliso, esenza inkqubo epheleleyo yemizi-mveliso. Ngoku,umhlaba onqabileyoUkuhlaziywa eTshayina
I-ore spelting kunye nokwahlulahlulahlula iitoni ezingaphezu kwe-130000 ngonyaka (reo), kunye nemveliso yonyaka enqabileyo ifikelela kwi-70000 yeetoni, inika ingxelo ngaphezulu kwe-80% yemveliso epheleleyo yehlabathi. Imveliso yayo kunye nevolumu yokuthumela ngaphandle yehlabathi inkulu yehlabathi.
Kukho ngaphezu kwe-170umhlaba onqabileyoUkunyibilika kunye namashishini okuqhawule i-China, kodwa kuphela i-5 amandla onyaka aphezulu kuno-5000 iitoni (reo), ngamashishini amaninzi anetoni ye-1000-2000.
Okwangoku, i-China yenze iziseko ezintathu zokuvelisa ikakhulu zijikeleze ezintathu eziphambiliumhlaba onqabileyoIzixhobo:
(1) OmaNtlaumhlaba onqabileyoIsiseko semveliso senziwe nge-baotou exubeneyoumhlaba onqabileyoI-ore njengezixhobo ezibukhali, kunye ne-baotouUmhlaba onqabileyoInkampani yaseTech yeTech kunye neGanssu enqabileyo. Kukho amashishini angaphezu kwama-80 avelisaumhlaba onqabileyoIikhemikhali ezinjeI-nqabile yomhlaba onqabileyokunye ne-carbonate minyaka le
Ngaphezulu kwe-60000 yeetoni zeekhomputer kunye neetoni ezili-15000 zezodwaumhlaba onqabileyoimichiza. Okwangoku, uninziumhlaba onqabileyoAmashishini aqhubela phambili ukusebenzisa i-ore ye-acid sylting ephuhliswe yiBeijing Institute Institute Institute Institute Institute Institute Institute Institute Institute Institute Institute Institute Institute Institute Institute Institute Institute Institute Institute Institute Institute Infortute i-P204 okanye i-P507 yokukhuphela sUKHONA,I-cerium ecocekileyo ephezuluikhutshiwe ngokubanzi ngokukhutshwa kwe-oxidation, kunye nebanga le-fluorescentI-Europim Oxideikhutshwe ngokunciphisa. Iimveliso eziphambili zibandakanya imibandela engatshatanga okanye exutywe yomhlaba efana nei-lanthanum, i-cerium, I-Praseodziyoium, I-Neodmium, I-Sarium, I-Europium, njl.
(2) Iphakathi kunye nobunzimaumhlaba onqabileyoIsiseko semveliso sithatha i-ores esemazantsi e-Ores njengezixhobo eziluhlaza, kwaye ziphatha phantse iitoni ezingama-20000 zohlobo lwe-Ionicumhlaba onqabileyoi-ores minyaka le. Amashishini asemva aquka iGunanzhou i-Pearl River Smelter, Jianyin JoimauaUmhlaba onqabileyoUmzi-mveliso, kunye neYixin xinwei enqabileyo Count Count Count, Liyadiya fare sul super speciation kunye nokucoca i-Hyddoric Aid.
Iphakathi ukuya kwi-hardI-ox ox ox ox oxkunye nezinye izithintelo ezityetyisiweyo ezinjeyttrium, dysprosium, I-Terbium, I-Europium, i-lanthanum, I-Neodmium, I-Sarium, njl.
. Okwangoku kukho izityalo ze-Hydrometallgergy ezinomphumo wonyaka zizonke zetoni ye-15-2000. Inkqubo yokunyibilika ye-fluoride ore kunyei-ceriumOre ikakhulu ibandakanya ukuqhutywa kwe-oxidation vIinkqubo zonyango ezihle zonyango ezivela kwinkqubo ephambili yokugcoba i-sulfuric leaching, kunye neemveliso ezizezona okanye zomhlaba ezixubeneyo zomhlaba ezixineneyoi-lanthanum, i-cerium, kwayeI-Neodmium. Uninzi lwamashishini aluncinci kakhulu emncinci, ngezixhobo eziphantsi kunye nenqanaba lezobugcisa.tNazi iimveliso eziphambili eziphambili ngaphakathiumhlaba onqabileyoUkunyibilikisa iimveliso, ngococeko oluphezulu kunye neemveliso ezinqabileyo zomhlaba ezinqabileyo kuqikelelwa ukuba zingadluli kwi-5%.
