Ukusetshenziswa kwe-ammonium sulfate yezimayini zomhlaba ezingavamile

Ukusetshenziswa kwe-ammonium sulfate ezimayini zezakhi zomhlaba ezingavamile

 

Izakhi zomhlaba ezingavamile (ama-REE) ziyiqembu lamakhemikhali angu-17, ahlanganisa izakhi ze-lanthanide ezingu-15 kanye ne-scandium ne-yttrium. Adlala indima ebaluleke kakhulu kwezobuchwepheshe besimanje futhi asetshenziswa kakhulu emikhakheni ehlukahlukene efana ne-electronics, amandla, ezempi, ezokwelapha, kanye nokuvikelwa kwemvelo. I-Ammonium sulfate, njenge-reagent yamakhemikhali ebalulekile yokukhipha izakhi zomhlaba ezingavamile, idinga ukuhlolwa okwengeziwe ekusetshenzisweni kwayo.

 

1. Ukubaluleka kwezakhi zomhlaba ezingavamile

 

Izakhi zomhlaba ezingavamile zibalulekile ekukhiqizeni imikhiqizo eminingi yobuchwepheshe obuphezulu, njenge:

 

Izinto zikazibuthe ezihlala unomphela: ezisetshenziselwa izinjini zikagesi, amajeneretha, ama-hard disk drive, njll.

I-Catalyst: isetshenziselwa ukucwenga kwe-petroleum, ukuhlanzwa kokukhipha umoya wezimoto, njll.

Izinto ze-Fluorescent: ezisetshenziselwa ukubonisa ithelevishini nekhompyutha, izibani ze-fluorescent, njll.

Ama-alloys ensimbi: Thuthukisa izakhiwo zama-alloys, njengamandla, ukumelana nokushisa, njll.

 

2. Ukumbiwa kwezakhi zomhlaba ezingavamile

 

Inqubo yezimayini yezakhi zomhlaba ezingavamile iyinkimbinkimbi, ehlanganisa izinyathelo eziningi ezifana nokuhlola indawo, izimayini, ukuchotshozwa, ukucwiliswa kwamanzi, imvula, ukuhlanzwa, njll. I-Ammonium sulfate idlala indima ebalulekile kule nqubo.

 

3. Indima ye-ammonium sulfate ezimayini zomhlaba ezingavamile

 

Ukushintshaniswa kwe-ion

 

I-Ammonium sulfate ihlangana nezakhi zomhlaba eziyivelakancane ku-ore ngokushintshana kwe-ion, okubangela ukuthi izakhi zomhlaba eziyivelakancane zidlule zisuka etsheni ziye exazululweni.

 

Ukuthuthukisa ukusebenza kahle kwe-leaching

Ukwengezwa kwe-ammonium sulfate kungathuthukisa ukusebenza kahle kwe-leaching yezinto ezingavamile zomhlaba futhi kunciphise ukumosheka kwezinsiza.

 

Ukwehliswa kwezindleko

 

Uma kuqhathaniswa namanye ama-reagents amakhemikhali, i-ammonium sulfate ishibhile futhi isiza ekunciphiseni izindleko zezimayini.

 

Ukugeleza kwenqubo ye-ammonium sulfate yezimayini zomhlaba ezingavamile

 

Ukuchotshozwa kwe-ore

 

Gcoba i-ore yomhlaba engavamile ukuze ukwandise indawo yokuxhumana phakathi kwe-ore nama-reagents amakhemikhali.

 

Leaching

 

Hlanganisa i-ore echotshoziwe nesisombululo se-ammonium sulfate ukuze uphendule ukuvuza.

 

Imvula

 

Ngokulungisa inani le-pH noma ngokungeza amanye ama-precipitants, izakhi zomhlaba eziyivelakancane zingahlukaniswa nesixazululo ngendlela yemvula.

 

Ukuhlunga nokugeza

 

Hlunga futhi ugeze inhlabathi ukuze ususe ukungcola.

 

Shisa

 

Shisa imvula ukuze uthole ama-earth oxides ayivelakancane.

 

4. Izinselele ekukhipheni izakhi zomhlaba ezingavamile nge-ammonium sulfate

 

Umthelela Wezemvelo

 

Ukusetshenziswa kwe-ammonium sulfate kungase kube nemithelela ethile endaweni ezungezile, njengokwenza inhlabathi i-acidification, ukungcoliswa kwamanzi, njll.

 

Izinga lokutholwa kwezinto ezingavamile zomhlaba

Indlela yokuthuthukisa izinga lokutholwa kwezinto ezingavamile zomhlaba kanye nokunciphisa ukuchithwa kwezinsiza kungenye inselele ebhekene nokumbiwa kwe-ammonium sulfate yezinto ezingavamile zomhlaba.

 

Amathrendi wesikhathi esizayo ezimayini ze-ammonium sulfate zomhlaba ezingavamile

 

Ngokukhula kwesidingo sezakhi zomhlaba ezingavamile, inqubo yokumba umhlaba ongavamile i-ammonium sulfate kulindeleke ukuthi ithuthukiswe futhi ithuthukiswe. Amathrendi entuthuko ezayo angase afake:

 

Ivumelana nemvelo: Ukuthuthukisa izinqubo zezimayini ezingayingeni imvelo ukuze kuncishiswe umthelela wendawo.

 

Thuthukisa ukusebenza kahle: Ngokusungula izinto ezintsha zobuchwepheshe, thuthukisa amazinga okuvuza nawokuthola kabusha kwezinto ezingavamile zomhlaba.

 

Ukusetshenziswa okuphelele kwezinsiza: ukuzuza ukusetshenziswa okuphelele kwezinsimbi zomhlaba ezingavamile kanye nokwenza ngcono ukusebenza kahle kwezinsiza.

 

I-Epilogue

 

Ukusetshenziswa kwe-ammonium sulfate ekukhishweni kwezakhi zomhlaba ezingavamile kubonisa ukubaluleka kwayo okubalulekile embonini yesimanje. Nakuba kunezinselelo ezithile, ngokusungula izinto ezintsha zobuchwepheshe kanye nokwenza ngcono inqubo, inqubo yokumbiwa kwe-ammonium sulfate yomhlaba ongavamile kulindeleke ukuba yenziwe ngcono, kube negalelo elikhulu ekuhlangabezaneni nesidingo sezakhi zomhlaba eziyivelakancane emphakathini.
