Background
Uma kuqhathaniswa nomhlabathi, imithombo ye-uranium emanzini olwandle ingachazwa nangokuthi “ayipheli”. Imithombo ye-uranium emanzini olwandle ingaba amathani ayizigidi eziyizinkulungwane ezingu-4.5, okulingana izikhathi eziyi-1,000 XNUMX nezimayini ze-uranium ezisemhlabeni. Ngokuqhubeka okuqhubekayo kobuchwepheshe bokukhipha i-uranium emanzini olwandle, uma imithombo ye-uranium emanzini olwandle ingasetshenziswa ngempumelelo esikhathini esizayo, iyokwanela ukuqinisekisa ukuthuthukiswa okusimeme kwamandla enuzi futhi ihlangabezane nesidingo somuntu samandla. Ngaphambilini, abacwaningi e-Oak Ridge National Laboratory kanye ne-Lawrence Berkeley National Laboratory e-United States bathola uhlobo olusha lwe-uranium sorbent yamanzi olwandle engavuselelwa futhi isetshenziswe kabusha ekhabhothini epholile. Ngokuthuthuka okuqhubekayo kokusebenza kwezinto zokumba i-uranium, inkinga yokushoda kwemithombo yezobuchwepheshe enganele ukuze kukhishwe i-uranium emanzini olwandle iye yanda kakhulu.
Abacwaningi base-Hainan University e-China benze isipontshi esikhethekile esingasetshenziswa ukusiza ukukhuculula imfucumfucu yenuzi, futhi okubaluleke nakakhulu, singasetshenziswa nokukhipha imithombo ye-uranium emanzini olwandle. Igwebu le-melamine eliguquliwe elenziwe ngegwebu le-melamine, le nto isetshenziswa kakhulu ekuhlanzeni isipontshi sasendlini, ukuncishiswa komsindo wokwakha, ukufakwa kwezimoto zikaloliwe, izinto ezimunca umsindo wezimoto nezinye izinkambu. Igwebu le-melamine linezinga leseli elivulekile eliphezulu elingu-99%, futhi izinga lokumunca amanzi/uketshezi liphindwe izikhathi ezingu-90 kwesisindo sayo.
Igwebu le-melamine licwiliswe esixazululweni esiqukethe ikhemikhali elibopha kalula i-uranium nokomiswa emoyeni. Isakhiwo sangaphakathi sesipontshi sishiya ngemuva kwefilimu yamakhemikhali. Lapho isipontshi sicwiliswa amathani amahlanu amanzi olwandle amasonto angu-1.9, samunca cishe amamiligremu angu-XNUMX e-uranium igremu ngalinye, elilingana nenani elikhiqizwa ezinye izindlela zokuthola i-uranium olwandle. Uma kuqhathaniswa nezinye izindlela zokukhipha i-uranium kusetshenziswa ipulasitiki, izipantshi ze-melamine zibola kakhulu futhi ngenxa yalokho aziyingcolisi imvelo.
Ngemva kokuba i -melamine foam eguquliwe imunce i-uranium, ithola umbala ophuzi ofana nalesi sakhi. Ngokuhlambulula, i-uranium ingakhishwa njengophethiloli wezitshalo zamandla enuzi. Isiponji singabekwa kabusha olwandle. Isiponji silahlekelwa ukusebenza kahle kwaso ngenqubo ngayinye yokuvuselela ngoba sakha ezinye izinto okunzima ukuzihlanza, futhi lokhu kudala inkinga ngokusetshenziswa komkhiqizo omningi njengamanje. Le ndlela okwamanje ibiza kakhulu kunokumba i-uranium, kodwa lapho iminerali isiphelile ekugcineni, kungasetshenziswa izinto ezincane zesiponji, ezingasuswa olwandle. Thola inani elikhulu likaphethiloli wenuzi, elidlala indima ebaluleke kakhulu ekukhishweni kwe-uranium emanzini olwandle.
Njengamanje, indlela elula yokuthola i-uranium iwukuqala ukumba nge-ore engaphansi komhlaba. Kudingeka idlule ohlelweni oluyinkimbinkimbi kakhulu, okuhlanganisa ukuhlola, ukumba izimayini, ukuhlomula, ukucwiliswa, ukuncibilikisa, ukucwenga nezinye izinqubo. Uma obunye ubuchwepheshe bokukhipha i-uranium emanzini olwandle bungathuthukiswa, bungalawulwa ngokukhetha ukulawula ukulawula amandla amaningi olwandle. Ngesikhathi esifanayo, ucwaningo lobuchwepheshe kanye nokuthuthukiswa kokukhipha i-uranium emanzini olwandle kufanele inake inhlanganisela nezimboni ezivuthiwe ezifana nokukhipha usawoti emanzini olwandle kanye nokukhipha usawoti wasolwandle, ukuze kubonakale ukusetshenziswa okuphelele kwemithombo yasolwandle.
I-SINOYQX izohlinzeka ngezinto zamahhala ze-melamine foam zezikhungo ezinkulu zocwaningo lwesayensi zocwaningo nokuthuthukiswa kwezinto eziguquliwe ze-melamine foam uranium.
