Kudiwa kwezvinhu zvepasi rose zve rare earth element (REE) kuchasvika matani 315,000 panosvika gore ra2030, zvichikonzerwa nekugadzirwa kwemotokari dzemagetsi, simba remhepo, uye zvemagetsi. Kuwanikwa kwezvinhu izvi kunodziviswa nekuwanikwa kutsva kushoma uye mitengo yakawanda yekupinda. Nzira dzekutsvaga zvicherwa zve rare earth dzinoshanda, kusanganisira kuunganidzwa kwehuwandu hwakawanda hwezvinhu uye kuongorora nekukurumidza, dzinoderedza kutenderera kwekutsvaga kusvika pakugadzirwa, zvakakosha kana mapurojekiti epasi rose achiwanzopfuura nemwedzi 12-24. Nyika dzine ongororo dzinokurumidza, dzakadai seChina neAustralia, dzakatora chikamu chinodarika 80% chemusika kubvira muna 2017. Kuongororwa kwezvinhu zve rare earth element kwakagadziriswa kunoita kuti kugoverwa kwezviwanikwa kuve nani, zvichisimbisa kukwikwidzana sezvo kusagadzikana kwemusika kuchikwira.

Matambudziko mukugadzirisa zvicherwa zveRare Earth neMatope eMarara
Kubviswa kwezvicherwa zvisingawanzoonekwi kunosangana neruzivo rwakaoma rwekuchera zvicherwa. Monazite nebastnaesite zvinoda kupatsanurwa kwemakemikari zvine simba, izvo zvinokwidza mari yekugadzirisa uye njodzi yezvakatipoteredza. Kubviswa kweasidhi yechinyakare kunogadzira huwandu hwakawanda hwezvicherwa zvine chepfu zvine thorium, uranium, uye fluorides. MuBayan Obo, nzvimbo dzezvicherwa dzinofukidza anopfuura 10 km² uye dzine njodzi yekusvibiswa kwenguva refu kwemvura yepasi pevhu. Nzira dzemazuva ano dzekugadzirisa zvicherwa zvisingawanzoonekwi dzinovavarira kuwedzera mwero wekudzoreredza pamusoro pe85% uye kuderedza zvinopinda mumakemikari, asi zvipingamupinyi zvehunyanzvi nehupfumi zvinoramba zviripo. Mhedzisiro yezvehupfumi dzinosanganisira kurasikirwa nenyika, mvura isina simba, uye nharaunda dzakakanganiswa, dzinowanzobatanidzwa nenzira dzekuchera dzekare. Maitiro anoshanda ekutarisira zvicherwa zvisingawanzoonekwi, kusanganisira kurasa zvakachengeteka zvicherwa zvisingawanzoonekwi uye kutarisa zvinhu panguva chaiyo, zvakakosha kuti pave nekuchengetedzwa uye kutevedzera mitemo. Kukundikana kugadzirisa kukanganisa kwezvicherwa zvisingawanzoonekwi kunogona kukonzera zvikwereti zvekuchenesa zvinodarika $100 miriyoni panzvimbo imwe neimwe. Maitiro akavandudzwa, anotsigirwa nekuongororwa nekukurumidza kweXRF mukutsvaga zvicherwa, anogonesa kuderedza marara akanangwa uye maitiro akachengeteka ekugadzirisa.
Tekinoroji dzekuongorora muMigodhi yeRare Earth
Kuenzanisa Nzira Dzekuongorora Dzakajairika Nedzinotakurika
ICP-MS, LIBS, uye hyperspectral imaging ndiyo nzira dzakajairika dzekutsvaga zvicherwa zvepasi. ICP-MS inowana miganho yekuona kusvika pamazinga eppt e lanthanides, asi kugadzirira sampuro kunoda kugaya acid uye zvivakwa zvemu lab. LIBS inogonesa in-situ laser ablation, asi matrix effects uye sample heterogeneity zvinokanganisa kurongeka. Hyperspectral imaging inotarisa zvicherwa munzvimbo dzakafara, asi kuyera kweREEs hakuna kunanga uye kunoda kugadziriswa mushure menguva. Nzira dzese dzechinyakare dzinodhura zvakanyanya vashandi, kunonoka kudzoreredza, uye mutoro wekutakura; kunonoka kwekuongorora mu lab kwakajairika mazuva mashanu kusvika gumi nemashanu ekushanda nemari yesampuli imwe neimwe inodarika $50–$200 zvichienderana nekuoma kwezvicherwa. Huwandu hwesampuro hunodziviswa nekushandiswa kwe lab, kazhinji zvichideredza dense blast hole sampling uye kuwedzera njodzi dzekusarongeka kwemunhu wese.
Nhanganyaya yekuongorora kweXRF kunotakurika
Zviyereso zveXRF zvinofambiswa nemachubhu zvinogonesa kuyedzwa zvakananga, panzvimbo yacho kwezvinhu zvakasimba zvemineral uye tailings. XRF inoshanda neatomu dzesample dzinofadza neX-rays, ichigadzira element-specific spectra iyo inoyera REEs—kusanganisira lanthanides, yttrium, uye scandium—mukati memaminitsi ekuyera. Lonnmeter XRF mineral analyzer inowana miganhu yekuona pa low ppm ye rare earths, inobata matrices akaomarara eore, uye inopa nekukurumidza batch analysis mumapoinzi akawanda esample zuva nezuva. Izvi zvinobvisa kutumira kwesamples, zvinoderedza kuvimba ne central labs, uye zvinobvumira kugadzika mapping nguva dzose ne spatial density yakakwira. Onsite XRF assays inoderedza mitengo ye lab ne logistics kusvika ku80% uye inogonesa gredi control feedback nekukurumidza panguva yeku drill hole sampling ye minerals, ichitsigira nzira dzinoshanda dze rare earth extraction uye rare earth tailings management.
Kuenzanisa Maburi Ekuputika uye Kuongorora kweXRF: Kuchengetedza Mari Yekushanda
Maitiro enguva dzose anoenderana nekuongororwa kwemakomba emaminerari, kuunganidzwa kwemasampuli nemaoko, kurongedza kwakavharwa, uye kutumirwa kuma laboratories ari kunze kwenzvimbo. Kugadziriswa kwakajairika kwemazuva maviri kusvika gumi pachikamu chimwe nechimwe; mitengo inotangira pamadhora gumi nemashanu kusvika makumi mashanu pachikamu chimwe nechimwe, zvichisanganisira mari yekufambisa uye yekuongorora. Kunonoka kwemaitiro ekuongorora zvicherwa akavakirwa murabhoritari enzvimbo dzisina kupfuma kunowedzera njodzi dzekusashandiswa zvakanaka kwenzvimbo - zvichikonzera kurasikirwa nematombo kana kugadziriswa kwemarara zvisina kufanira.
Kuongorora kweXRF kunotakurika kunoita kuti kutsvaga zvicherwa kuve nyore, zvichiita kuti kuongororwa nekukurumidza kuonekwe zvakananga pagomba rinoputika. Kuongorora panzvimbo yacho kunowedzera huwandu hwemakomba anoongororwa pakuchinjana kwechinhu ne3–5×, zvichideredza kudiwa kwekuboorwa kusingachadiwi. Mari yevashandi neyekufambisa zvinhu inoderera kusvika ku70% nemhedzisiro yekukurumidza uye kubviswa kwesampuli yekutumira.
Nzira dzekutsvaga, kugadzirisa, uye nzira dzekutarisira marara evhu risingawanikwe zvese zvinobatsira kubva pakuwanikwa kwedata nekukurumidza. Sarudzo dzinokurumidza dzinoderedza kurasikirwa kusina kunanga—mienzaniso inosanganisira kudzikiswa kwekusarongeka kwematombo uye simba shoma rinoshandiswa pamatombo asina chinhu, zvichichengetedza $20,000–$100,000 pamwedzi panzvimbo dzakakura.
Mabhenefiti Ezvakatipoteredza Nemitemo
Kugadzira mapu emhando yepamusoro neLonnmeter kunotsigira nzira dzekutarisira marara emunyika, zvichideredza kukanganisa kwemarara emunyika. Muchina uyu unoongorora huwandu hwenzvimbo dzinobuda ammonia uye kupararira kwemarara, zvichibatsira kutevedzera mitemo inotarisa kuburitswa kwemarara kubva mukuchera zvicherwa. Kupindira kwakachengeteka kwemarara emunyika kunoenderana nekuongorora kweXRF kwemasampuli emaburi ekuputika kuti vaone kuti anodzivirira zvakakwana, zvichideredza kushandiswa kwemarara zvisina kufanira.
Kuwedzera ROI by In-Situ XRF Mineral Instrupfungwas
Nguva yekupindura mienzaniso inoderera kubva pamazuva 3-7 kusvika pasi pemaminitsi mashanu paburi rega rega, zvichideredza mari yekumirira kusvika 70%. Mumapurojekiti anoshandisa nzira dzekare dzekutsvaga zvicherwa zvisingawanzoitiki, kuongororwa kweXRF panzvimbo yekutsvaga zvicherwa kunochengetedza $30-$70 pasample imwe neimwe pakutumira, kubata, uye kuongorora murabhoritari. Kuongororwa kwemakomba ekuboorwa kwakagadziriswa uye kunatsiridzwa kwesimbi kunokonzera kuwedzera kwakanyorwa kwe12-20% mukudzoserwa kwezviwanikwa, zvichideredza kugadziriswa kwezvinhu zvisiri zvesimbi uye mari inoenderana nazvo.
Vashandi vanoongorora zvinodiwa pakushanda kwenzvimbo zvichibva panzira dzekutora sampuli dzemakomba anoputika uye nzvimbo. Ruzivo rwepurojekiti, kubatanidzwa nesoftware yekuronga zvicherwa, uye mishumo yezvakatipoteredza yekubvisa zvicherwa zvisingawanzoonekwi. Kuti utange kuisirwa, taura mafambiro ebasa rako, mafambiro aunoda, uye mitemo inorambidza.
