I-Beryllium Resource kunye ne-Extraction

I-Beryllium yintsimbi enqabileyo ekhanyayo, kwaye izinto ezingenayo i-ferrous ezidweliswe kolu luhlu ziquka i-lithium (Li), i-rubidium (Rb), kunye ne-cesium (Cs).Oovimba be-beryllium kwihlabathi bangama-390kt kuphela, imveliso ephezulu yonyaka ifikelele kwi-1400t, kwaye unyaka ophantsi umalunga ne-200t kuphela.I-China lilizwe elinemithombo enkulu ye-beryllium, kwaye imveliso yayo ayizange idlule i-20t / a, kwaye i-beryllium ore ifunyenwe kumaphondo e-16 (imimandla yokuzimela).Zingaphezu kwama-60 iintlobo zeeminerali zeberyllium kunye neeminerali ezineberyllium ezifunyenweyo, kwaye malunga neentlobo ezingama-40 zixhaphakile.I-Xianghuashi kunye ne-Shunjiashi e-Hunan yenye yeediphozithi zokuqala ze-beryllium ezifunyenwe e-China.I-Beryl [Be3Al2 (Si6O18)] iyona minerali ibaluleke kakhulu yokukhupha i-beryllium.Umxholo wayo yi-9.26% ~ 14.4%.I-beryl enhle ngokwenene i-emerald, ngoko kunokuthiwa i-beryllium ivela kwi-emerald.Ngendlela, nali ibali malunga nendlela i-China yafumanisa ngayo i-beryllium, i-lithium, i-tantalum-niobium ore.

Phakathi kwiminyaka yoo-1960, ukuze kuphuhliswe "iibhombu ezimbini kunye nesathelayithi enye", i-China yayidinga ngokukhawuleza iintsimbi ezinqabileyo ezifana ne-tantalum, i-niobium, i-zirconium, i-hafnium, i-beryllium, kunye ne-lithium., "i-87" ibhekiselele kwinombolo yesiriyali yeprojekthi kwiprojekthi engundoqo yesizwe yi-87, ngoko ke iqela lokuhlola eliqulunqwe ziingcali zejoloji, amajoni kunye neenjineli kunye neechwephesha zasekwa ukuya kumda osemantla-mpuma weJunggar Basin eXinjiang, Irtysh In. umhlaba oyintlango nongumqwebedu osemazantsi omlambo, emva kwemigudu enzima, ekugqibeleni ummandla wemigodi waseCoketuohai wafunyanwa.Abasebenzi beprojekthi "i-6687" bafumene imigodi emithathu ebalulekileyo yentsimbi enqabileyo, i-01, i-02 kunye ne-03, kwi-Keketuohai No. 3 Mine.Enyanisweni, i-ore 01 i-beryl isetyenziselwa ukukhupha i-beryllium, i-ore 02 yi-spodumene, kunye ne-ore 03 yi-tantalum-niobite.I-beryllium ekhutshiweyo, i-lithium, i-tantalum, kunye ne-niobium ibaluleke kakhulu kwi-China "iibhombu ezimbini kunye neenkwenkwezi enye".indima ebalulekileyo.Umgodi woLwandle lwaseCocoto uphinde waphumelela udumo "lomngxuma ongcwele we-geology yehlabathi".

Kukho ngaphezu kwe-140 iintlobo zeeminerali ze-beryllium ezinokugrunjwa emhlabeni, kwaye kukho iindidi ezingama-86 zeeminerali ze-beryllium kumgodi we-Cocotohai 03.I-beryllium esetyenziswe kwi-gyroscopes ye-missile ye-ballistic, ibhomu yokuqala ye-athomu, kunye nebhomu yokuqala ye-hydrogen kwiintsuku zokuqala zeRiphabhlikhi yaseChina yonke ivela kwi-6687-01 mineral kuLwandle lwaseCocoto, kunye ne-lithium esetyenziswe ekuqaleni. ibhombu yeathom yavela kumgodi we-6687- 02, i-cesium esetyenziswa kwisathelayithi yomhlaba eyenziweyo eNtsha yaseTshayina nayo iphuma kulo mgodi.

Ukukhutshwa kwe-beryllium kukuqala ukukhupha i-beryllium oxide kwi-beryl, kwaye emva koko ivelise i-beryllium kwi-beryllium oxide.Ukukhutshwa kwe-beryllium oxide kubandakanya indlela ye-sulfate kunye nendlela ye-fluoride.Kunzima kakhulu ukunciphisa ngokuthe ngqo i-beryllium oxide kwi-beryllium.Kwimveliso, i-beryllium oxide iqala ukuguqulwa ibe yi-halide, kwaye iyancipha ibe yi-beryllium.Kukho iinkqubo ezimbini: indlela yokunciphisa i-beryllium fluoride kunye ne-beryllium chloride etyhidiweyo indlela ye-electrolysis yetyuwa.Amaso e-beryllium afunyenwe ngokunciphisa i-vacuum encibilikisiwe ukususa i-magnesium engaphendulwanga, i-beryllium fluoride, i-magnesium fluoride kunye nobunye ukungcola, kwaye emva koko iphonswe kwiingots;i-electrolytic vacuum smelting isetyenziselwa ukuphosa kwiingots.Olu hlobo lwe-beryllium ludla ngokubizwa ngokuba yi-beryllium ecocekileyo yezoshishino.

Ukuze kulungiswe i-beryllium ecocekileyo, i-beryllium ekrwada inokusetyenzwa nge-vacuum distillation, i-electrorefining yetyuwa etyhidiweyo okanye ukunyibilikiswa kwendawo.
