Iintsimbi zomhlaba ezinqabileyo zokuhombisa

Imfazwe yorhwebo yase-US-China inyuse uloyiko malunga nokunyuka kweTshayina ngokurhweba ngesinyithi somhlaba esinqabileyo.

 

Malunga

• Ukunyuka kwengxabano phakathi kwe-United States ne-China kubangele inkxalabo yokuba i-Beijing ingasebenzisa isikhundla sayo esiphezulu njengomthengisi womhlaba onqabileyo ukuze abe namandla kwimfazwe yorhwebo phakathi kwamagunya amabini oqoqosho lwehlabathi.

 

Zeziphi iinyithi ezinqabileyo zomhlaba?

• Iintsimbi zomhlaba ezinqabileyo liqela lezinto ze-17 - i-lanthanum, i-cerium, i-praseodymium, i-neodymium, i-promethium, i-samarium, i-europium, i-gadolinium, i-terbium, i-dysprosium, i-holmium, i-erbium, i-thulium, i-ytterbium, i-lutetium, i-scandium, i-yttrium ebonakala iphantsi emhlabeni.

• Zinqabile kuba zinzima kwaye zibiza imali eninzi emigodini kwaye zilungiswa ngokucocekileyo.

• Umhlaba onqabileyo wembiwa eTshayina, eIndiya, eMzantsi Afrika, eKhanada, eOstreliya, e-Estonia, eMalaysia naseBrazil.

Ukubaluleka kweZinyithi zoMhlaba ezinqabileyo

• Zineempawu ezikhethekileyo zombane, isinyithi, i-catalytic, inyukliya, imagnethi kunye nezikhanyiso.

• Zibaluleke kakhulu ngokweqhinga ngenxa yokusebenzisa kwabo ubugcisa obuvelayo nobohlukeneyo obubonelela iimfuno zoluntu lwangoku.

• Ubuchwephesha bexesha elizayo, umzekelo, ubushushu obuphezulu obuphezulu, ugcino olukhuselekileyo kunye nokuthuthwa kwe-hydrogen kufuna ezi zinyithi zomhlaba ezinqabileyo.

• Imfuno yehlabathi yee-REMs ikhula ngokuphawulekayo ngokuhambelana nokwanda kwazo kwi-high-end technology, imo engqongileyo, kunye nemimandla yezoqoqosho.

• Ngenxa yeempawu zabo ezizodwa zemagneti, ukukhanya, kunye ne-electrochemical, bancedisa kwiiteknoloji ukusebenza ngobunzima obuncitshisiweyo, ukukhutshwa okucuthiweyo, kunye nokusetyenziswa kwamandla.

 

Usetyenziso lwezinyithi ezinqabileyo zomhlaba

• Izinto ezinqabileyo zomhlaba zisetyenziswa kuluhlu olubanzi lweemveliso zabathengi, ukusuka kwii-iPhones ukuya kwiisathelayithi kunye neelaser.

• Zikwasetyenziswa nakwiibhetri ezitshajwayo ngokutsha, iiseramikhi eziphambili, iikhompyutha, ii-DVD player, iiinjini zomoya, iicatalysts ezimotweni nakwizinto zokucoca i-oyile, iimonitha, oomabonakude, izibane, iifiber optics, ii-superconductors kunye ne-glass polishing.

• I-E-Vehicles: Izinto ezininzi ezinqabileyo zomhlaba, ezifana neodymium kunye ne-dysprosium, zibalulekile kwiimotor ezisetyenziswa kwizithuthi zombane.

• Izixhobo zomkhosi: Ezinye izimbiwa zomhlaba ezinqabileyo zibalulekile kwizixhobo zomkhosi ezinjengeenjini zejethi, iinkqubo zokukhokela imijukujelwa, iinkqubo zokhuselo lokulwa, iisathelayithi, kunye neelaser. ILanthanum, umzekelo, iyafuneka ukwenza izixhobo zokubona ebusuku.

 

Ukubaluleka kweTshayina kwi-US wrt Rare Earth Elements (REE)

• I-China likhaya kuma-37% oovimba bomhlaba obunqabileyo behlabathi. Ngo-2017, i-China yenza i-81% yemveliso yomhlaba enqabileyo yehlabathi.

• I-China ibambe uninzi lwamandla okusebenza ehlabathini kwaye ibonelele nge-80% yomhlaba onqabileyo ongeniswe eMelika ukusuka ngowama-2014 ukuya kowama-2017.

• Umgodi weMountain Pass waseCalifornia kuphela kwesixhobo somhlaba esinqabileyo sase-US esisebenzayo. Kodwa ithumela inxalenye enkulu yesicatshulwa ukuya eTshayina ukuze iqhutywe.

• I-China ibeke umrhumo wama-25% kwezo zinto zingeniswayo ngaphandle ngexesha lemfazwe yorhwebo.

Isikhundla saseIndiya

• I-China, i-Australia, i-US kunye ne-Indiya yimithombo ebalulekileyo yehlabathi yezinto ezinqabileyo zomhlaba.

• Ngokoqikelelo, oovimba bomhlaba onqabileyo bebonke eIndiya ziziitoni ezizigidi ezili-10.21.

• I-Monazite, equlethe i-thorium kunye ne-Uranium, ngowona mthombo oyintloko wehlabathi elinqabileyo eIndiya. Ngenxa yobukho bezi zinto zeradioactive, ukumbiwa kwesanti yemonazite kwenziwa liqumrhu likarhulumente.

• I-Indiya ubukhulu becala ibingumnikezeli wezinto zomhlaba ezinqabileyo kunye nesiseko somhlaba onqabileyo. Asikwazanga ukuphuhlisa iiyunithi zokulungisa izinto ezinqabileyo zomhlaba.

• Ukuveliswa kwexabiso eliphantsi yi-China ngoyena nobangela wokuhla kwemveliso yomhlaba enqabileyo eIndiya.
