Ubusabe bw'ibintu by'ubutaka budasanzwe ku isi (REE) buzagera kuri toni 315.000 mu 2030, bitewe n'ibinyabiziga bikoresha amashanyarazi, ingufu z'umuyaga, n'ibikoresho by'ikoranabuhanga. Itangwa ry'ibintu ribangamiwe n'ibintu bishya bivumburwa bike n'ibiciro biri hejuru byo kwinjira. Uburyo bwiza bwo gushakisha amabuye y'agaciro y'ubutaka budasanzwe, harimo gupima ubucucike bwinshi n'isesengura ryihuse, bigabanya uruziga rwo gushakisha kugeza ku musaruro, bikaba ari ingenzi cyane iyo imishinga mpuzamahanga ikunze kurenza amezi 12-24. Ibihugu bifite ubushakashatsi bwihuse, nk'Ubushinwa na Ositaraliya, byigaruriye igice kirenga 80% by'isoko kuva mu 2017. Gushakisha neza ibintu by'ubutaka budasanzwe bituma habaho igabanywa ry'umutungo mwiza, bikongera imbaraga mu guhangana uko isoko rihindagurika.

Imbogamizi mu gutunganya amabuye y'agaciro n'imitako y'ubutaka bidasanzwe
Gucukura amabuye y'agaciro adasanzwe bihura n'ubushakashatsi bukomeye bw'amabuye y'agaciro. Monazite na bastnaesite bisaba gutandukanya cyane imiti, ibyo bikaba byongera ikiguzi cyo gutunganya no kwangiza ibidukikije. Gusukura aside gakondo bitanga ingano nini y'imyanda irimo thorium, uranium, na fluoride. Muri Bayan Obo, inyubako z'imyanda zirenga kilometero kare 10 kandi zitwara ibyago byo kwandura mu mazi yo mu butaka igihe kirekire. Uburyo bugezweho bwo gutunganya amabuye y'agaciro adasanzwe bugamije kongera igipimo cyo kugarura imyanda kirenze 85% no kugabanya ikoreshwa ry'imiti, ariko inzitizi za tekiniki n'ubukungu ziracyahari. Ingaruka ku mibereho y'abaturage zirimo igihombo cy'ubutaka, amazi mabi, n'abaturage bagizweho ingaruka, akenshi bifitanye isano n'uburyo bwo gucukura amabuye y'agaciro bwa kera. Ingamba zinoze zo gucunga imyanda y'amabuye y'agaciro adasanzwe, harimo no guta mu buryo bwizewe imyanda y'amabuye y'agaciro adasanzwe no gukurikirana ibintu mu buryo bufatika, ni ingenzi mu kubungabunga ibidukikije no kubahiriza amategeko. Kunanirwa gucunga ingaruka z'imyanda y'amabuye y'agaciro adasanzwe ku bidukikije bishobora gutuma habaho imyenda irenga miliyoni 100 z'amadolari kuri buri kibanza. Amabwiriza meza, ashyigikiwe n'igeragezwa ryihuse rya XRF mu gushakisha amabuye y'agaciro, bituma habaho kugabanya imyanda ku buryo bwizewe no gutunganya neza.
Ikoranabuhanga mu isesengura mu bucukuzi bw'amabuye y'agaciro adasanzwe
Kugereranya uburyo busanzwe n'uburyo bwo gusesengura bugendanwa
ICP-MS, LIBS, na hyperspectral imaging ni bwo buryo busanzwe bwo gushakisha amabuye y'agaciro adasanzwe. ICP-MS igera ku ngano ntarengwa yo gupima lanthanides, ariko gutegura icyitegererezo bisaba igogora rya aside n'ibikorwa remezo bya laboratwari. LIBS ituma habaho kwimura hakoreshejwe laser muri situ, ariko ingaruka za matrix n'ubusumbane bw'icyitegererezo bigira ingaruka ku buryo buboneye. Ishusho ya hyperspectral igereranya amabuye y'agaciro mu bipimo binini by'ahantu, ariko gupima REEs ntabwo ari ibintu bitaziguye kandi bisaba ko ikorwa nyuma yo kuyatunganya. Uburyo bwose busanzwe butwara ikiguzi kinini cy'abakozi, gutinda gukora, no kuremererwa mu bikoresho; gutinda gusesengura laboratwari ni iminsi 5-15 y'akazi, amafaranga kuri buri cyitegererezo arenga $50–$200 bitewe n'ubucucike bw'amabuye y'agaciro. Ingano y'icyitegererezo igengwa n'uburyo laboratwari ikora, akenshi ikagabanya ifatwa ry'imyobo myinshi yo guturika no kongera ibyago byo kwimura nabi umuntu wese.
Intangiriro ku isesengura rya XRF rigendanwa
Imashini zipima XRF zikoresha umuyoboro zikora zituma habaho igeragezwa ryimbitse ry’ibikoresho by’ubutare n’ibice bito. XRF ikora ikoresheje atome zikora ingero zishimishije hamwe na X-rays, ikora spectra yihariye y’ibintu bipima REEs—harimo lanthanides, yttrium, na scandium—mu minota mike buri gipimo. Imashini ipima ubutare ya Lonnmeter XRF igera ku rugero rwo hasi rwa ppm ku butaka buto, ikora ku miterere y’amabuye y’agaciro akomeye, kandi igatanga isesengura ryihuse ku ngingo nyinshi z’ingero buri munsi. Ibi bikuraho kohereza ingero, bigabanya kwishingikiriza kuri laboratwari zo hagati, kandi bikemerera gukomeza gukora ikarita ifite ubucucike bwinshi bw’ahantu. Isuzuma rya XRF rigabanya ikiguzi cya laboratwari n’ibikoresho kugeza kuri 80% kandi rigatuma habaho uburyo bwo kugenzura amanota ako kanya mu gihe cyo gupima imyobo y’amabuye y’agaciro, rigashyigikira ingamba zo gukuramo amabuye y’agaciro y’ubutare buto n’ubucucike bw’ubutaka buto.
Gupima Umwobo w'Ibisasu n'Isesengura rya XRF: Kuzigama Ikiguzi cy'Imikorere
Imikorere isanzwe ishingira ku gupima imyobo yo gucukura amabuye y'agaciro, gukusanya ingero n'intoki, gupfunyika bifunze, no koherezwa muri laboratwari zitari aho zikorera. Ibiciro bisanzwe ni iminsi 2-10 kuri buri cyiciro; ibiciro biri hagati ya $15–$50 kuri buri cyiciro, bigashyirwa mu mafaranga yo gutwara no gusesengura. Gutinda mu buryo bwo gupima amabuye y'agaciro bushingiye kuri laboratwari ku butaka budasanzwe byongera ibyago byo gutabwa mu buryo bubi—bigatera igihombo cy'amabuye y'agaciro cyangwa gutunganya imyanda bitari ngombwa.
Isesengura rya XRF rigendanwa ryoroshya ubushakashatsi bw'amabuye y'agaciro, rigatuma isuzuma ryihuse ku mwobo uturitswa. Isesengura ry'aho hantu ryongera umubare w'imyobo igenzurwa kuri buri hinduka ho 3-5×, bigabanya gukenera gucukura cyane. Ikiguzi cy'umurimo n'ibikoresho bigabanukaho kugeza kuri 70% bitewe n'ibisubizo byihuse kandi icyitegererezo cyo kohereza gikurwaho.
Ingamba zo gushakisha, gutunganya, no gucunga imyanda y’ubutaka budasanzwe byose bigira akamaro mu kubona amakuru ako kanya. Ibyemezo byihuse bigabanya igihombo kitaziguye—ingero zirimo kugabanya ishyirwa mu byiciro ry’amabuye y’agaciro no kugabanya ingufu zikoreshwa ku rutare rudafite amabuye, bikagabanya $20.000–100.000 ku kwezi ahantu hanini.
Inyungu ku bidukikije n'amategeko agenga ibidukikije
Gupima neza ibintu by’ibanze hakoreshejwe Lonnmeter bishyigikira ingamba zo gucunga imiyoboro y’ubutaka idasanzwe, bigabanya ingaruka ku bidukikije z’imiyoboro y’ubutaka idasanzwe. Iyi mashini isesengura ipima ahantu haturuka imyuka ihumanya ya ammonia n’ibice bikwirakwira, bigafasha kubahiriza amabwiriza ajyanye n’ibyuka bihumanya ikirere biva mu gucukura amabuye y’agaciro. Uburyo bwo gukora imiyoboro y’ubutaka bwizewe bushingiye ku isesengura rya XRF ku ngero z’imyobo y’ibisasu kugira ngo hamenyekane uburyo bwiza bwo kubika imyanda, bigabanye uburyo bwo kuyicukuramo bitari ngombwa.
Kongera inyungu y'amafaranga akoreshwa (ROI) by In-Situ XRF Mineral Instruigitekerezos
Igihe cyo gupima ingero kigabanuka kuva ku minsi 3-7 kugera munsi y'iminota itanu kuri buri mwobo uturitswa, bigabanyije ikiguzi cyo gutegereza kugeza kuri 70%. Mu mishinga ikoresha tekiniki zisanzwe zo gushakisha amabuye y'agaciro adasanzwe, isuzuma rya XRF mu gushakisha amabuye y'agaciro rizigama $30-70 kuri buri ngero mu gutwara, kuyakoresha no kuyasesengura muri laboratwari. Gupima ingero z'amabuye y'agaciro mu buryo bwiza no kuyacukura neza bituma habaho ukwiyongera kwa 12-20% mu kugaruza umutungo, bigagabanya ibiciro byo gutunganya ibikoresho bitari iby'amabuye y'agaciro n'ibindi bijyanye nabyo.
Abakora basuzuma ibikenewe mu mikorere hashingiwe ku buryo bwo gupima imyobo ituritswa n'ubutaka. Ingano y'amakuru y'umushinga, guhuza na porogaramu yo gutegura ibisasu, na raporo ku bidukikije ku bijyanye no gucukura amabuye y'agaciro adasanzwe. Kugira ngo utangire gushyiraho, garagaza imikorere yawe, umusaruro wifuza, n'amabwiriza agenga.
