Asayansi aku China apanga bwino mtundu wa kutumphuka kwanyengodziko losowaukadaulo wamigodi wa ore, womwe umachulukitsa kuchuluka kwa kuchira kwapadziko lapansi pafupifupi 30%, umachepetsa zonyansa ndi 70%, ndikufupikitsa nthawi yamigodi ndi 70%.Izi zidadziwidwa ndi mtolankhani pamsonkhano wowunika zomwe zachitika pasayansi ndiukadaulo womwe unachitikira mumzinda wa Meizhou, m'chigawo cha Guangdong pa 15th.
Zimamveka kuti weathered kutumphuka mtundudziko losowaminerals ndi chida chapadera ku China.Mavuto azachilengedwe, kugwiritsa ntchito bwino zinthu, kayendetsedwe ka madzi, ndi zina mwaukadaulo womwe amagwiritsidwa ntchito kwambiri ndi ammonium salt in-situ leaching pakali pano akulepheretsa kugwiritsa ntchito bwino komanso kobiriwira kwazinthu zachilendo ku China.
Poyankha mavuto okhudzana ndi izi, gulu la He Hongping lochokera ku China Academy of Sciences Guangzhou Institute of Geochemistry linapanga ukadaulo wa migodi yamagetsi opangira miyala yamtundu wa rare earth ores kutengera kafukufuku wokhudzana ndi kupezeka kwa dziko losowa kwambiri mumtundu wamitundu yosowa padziko lapansi. .Kuyesera koyerekeza, kuyesa kukulitsa, ndi ziwonetsero zakumunda zawonetsa kuti poyerekeza ndi momwe migodi ilipo kale, ukadaulo wamagetsi oyendetsa magetsi amtundu wamtundu wa rare earth ore wathandizira kwambiri kuchuluka kwa kuchira kwapadziko lapansi, kuchuluka kwa ma leaching agent, kuzungulira kwamigodi, ndi kuchotsa zonyansa, kupanga. ndi kothandiza ndi wobiriwira latsopano luso kwa weathered kutumphuka mtundu osowa lapansi ore migodi.
Zomwe zakwaniritsidwa zasindikizidwa m'mapepala apamwamba a 11 m'magazini monga "Nature Sustainability", ndipo zovomerezeka zovomerezeka za 7 zapezedwa.Ntchito yachiwonetsero yokhala ndi matani a 5000 a nthaka yamangidwa.Gulu lofufuza linanena kuti lithandizira kupititsa patsogolo luso lophatikizana ndiukadaulo ndikufulumizitsa kugwiritsa ntchito ntchito zamafakitale pazotsatira zomwe zakwaniritsa.
Msonkhano womwe uli pamwambapa wowunikira zomwe zakwaniritsa zasayansi ndiukadaulo udzakhalapo ndi akatswiri azamaphunziro ndi akatswiri odziwika bwino ochokera ku mayunivesite apakhomo, mabungwe ofufuza, ndi mabizinesi.
