Kev faib tawm thoob ntiaj teb ntawm phosphate pob zeb tsis sib npaug, Morocco yog lub ntiaj teb loj tshaj plaws phosphate resource reserves
Ua ntej, Morocco yog nplua nuj nyob rau hauv phosphate ntxhia cov peev txheej, suav txog 75 feem pua ntawm lub ntiaj teb tag nrho, qeb thib ib hauv ntiaj teb.
Phosphorite cov peev txheej yog nyob rau hauv daim ntawv ntawm Marine sedimentary phosphorite, nrog cov sedimentary deposits loj tshaj plaws nyob rau hauv North Africa, Tuam Tshoj, Middle East thiab lub tebchaws United States. Nyob rau tib lub sijhawm, ntau qhov xwm txheej igneous tau pom hauv Brazil, Canada, Finland, Russia thiab South Africa. Cov peev txheej phosphoric acid ntau muaj nyob rau ntawm cov txee sab av loj thiab cov dej hiav txwv ntawm Atlantic thiab Pacific dej hiav txwv.
Lub ntiaj teb cov khoom siv phosphate ore ntau tshaj 300 billion tons, suav nrog 71 billion tons ntawm cov peev txheej hauv paus. Cov peev txheej tseem ceeb tau muab faib rau hauv Africa, North America, Asia, Middle East thiab lwm thaj chaw, Africa thiab Middle East ua ke suav txog ze li 80 feem pua ntawm tag nrho lub ntiaj teb, ntawm uas ntau dua 85 feem pua yog nyob hauv Morocco, Western Sahara. , Egypt, Algeria thiab Tuam Tshoj. Morocco thiab Western Sahara ib leeg suav txog 70 feem pua ntawm lub ntiaj teb tag nrho, qhov siab tshaj hauv ntiaj teb.
Qhov thib ob, Tuam Tshoj kuj yog ib lub teb chaws loj hauv phosphate ore, nrog rau cov pov thawj tag nrho cov peev txheej thib ob tsuas yog Morocco, tab sis cov reserves ntawm qib siab phosphate ore muaj tsawg.
Peb lub teb chaws yog nplua nuj nyob rau hauv phosphate mineral peev xwm thiab tau txheeb xyuas cov mineral reserves ntawm 17.6 billion tons, nyob rau hauv qeb thib ob nyob rau hauv lub ntiaj teb no, tsuas yog nyob rau hauv Morocco thiab Western Sahara. Nws yog ib qho ntawm cov yam ntxwv ntawm cov khoom siv pob zeb phosphate hauv Suav teb uas muaj cov ore nruab nrab thiab qis dua thiab cov nplua nuj tsawg dua. 93 feem pua ntawm phosphate deposits hauv Suav teb yog qib nruab nrab thiab qis, nrog cov ntsiab lus siab impurity. Cov reserves ntawm qib siab phosphate ore nrog P2O5 ntau dua 30 feem pua tsuas yog 1.069 billion tons, suav txog tsuas yog 8.12 feem pua ntawm tag nrho cov reserves. Txawm hais tias suav nrog cov peev txheej nruab nrab ntawm cov phosphate ore nrog qib siab dua 26 feem pua yuav tsis pub tshaj 3 billion tons, nrog rau qib nruab nrab tsuas yog 16.95 feem pua.
Thib peb, lub ntiaj teb phosphorite ntau lawm cheeb tsam yog cov concentrated nyob rau hauv East Asia, Africa, North America, Tuam Tshoj yog lub ntiaj teb no tus loj tshaj plaws tsim ntawm phosphorite.
Tuam Tshoj, Tebchaws Meskas, Morocco, Western Sahara, Russia, Nyab Laj thiab lwm lub tebchaws yog cov neeg tsim khoom loj tshaj plaws ntawm phosphate pob zeb. East Asia tsim tawm ntau tshaj plaws, suav txog 36 feem pua ntawm cov khoom lag luam thoob ntiaj teb, tom qab ntawd Africa nrog 25 feem pua, North America nrog 11 feem pua, thiab West Asia, East Asia thiab Central Asia nrog 10 feem pua. Nyob rau hauv 2017, lub ntiaj teb no phosphate ore ntau lawm tau mus txog lub ncov tsis ntev los no ntawm 269 lab tons. Los ntawm 2018 txog 2020, nws tau txo mus rau 249 lab tons, 227 lab tons thiab 223 lab tons.
Qhia tawm ntawm Ntiaj Teb Phosphate Pob Zeb Ntau Lawm los ntawm Cheeb Tsam hauv 2020 (Cov ntaub ntawv qhov chaw: Cua)
Tam sim no, Tuam Tshoj cov khoom tsim tawm txhua xyoo ntawm phosphate ore yog ntau tshaj 60 lab tons, ntau dua li cov khoom tsim tawm hauv Tebchaws Meskas, Morocco thiab Western Sahara thiab lwm lub tebchaws lossis thaj chaw. Hubei (48%), Guizhou (23%), Yunnan (19%), Sichuan (7%) thiab Henan (2%) yog tsib lub xeev uas muaj phosphate ore ntau tshaj plaws hauv Suav teb. Ntawm lawv, hubei xeev tsim ntau tshaj 20 lab tons ntawm phosphate ore txhua xyoo, ua rau lub xeev hubei yog tus tsim khoom loj tshaj plaws hauv Suav teb. Txawm li cas los xij, cov khoom tsim tawm ntawm pob zeb phosphate hauv hubei tsuas yog 214, 000 tons, tsis tsuas yog qis dua li ntawm Yunnan-Guizhou (636,700 tons) thiab Guizhou (544,300 tons), tab sis kuj tseem qis dua li qhov nruab nrab ntawm lub teb chaws. 318,600t ib. Kev sib koom ua ke ntawm phosphate cov peev txheej hauv Hubei xeev thiab tag nrho lub tebchaws yuav yog qhov kev zam tsis tau yav tom ntej.
