Titanium ore thoob ntiaj teb feem ntau yog ilmenite, ntawm cov uas ze li ntawm 93.5% yog ilmenite thiab tus so yog rutile, anatase, titanium slag, thiab lwm yam. Raws li United States Geological Survey, lub ntiaj teb no titanium ore (tsuas yog ilmenite thiab rutile) tau mus txog 930. lab tons thaum kawg ntawm 2017, suav nrog 870 lab tons ntawm ilmenite hauv Australia, Tuam Tshoj, Is Nrias teb, South Africa, Kenya, Brazil, Madagascar, Norway, Canada, Mozambique, Ukraine, Tebchaws Asmeskas, thiab Nyab Laj; thiab 63 lab tons ntawm rutile (anatase suav nrog) faib hauv Australia, Kenya, South Africa, Is Nrias teb, Ukraine, Sierra Leone, Mozambique, thiab lwm yam. Nyob rau hauv xyoo tas los no, kev tsim cov titanium ore thoob ntiaj teb tau leveled tawm ntawm ntau tshaj 6 lab tons, ua Hauv tebchaws Australia, Canada, Tuam Tshoj, South Africa, thiab Mozambique. Feem ntau ntawm ilmenite tau tsim nyob rau hauv Australia, Tuam Tshoj, Canada, Mozambique, Nyab Laj, Norway, thiab lwm yam, nrog rau tag nrho ntawm 5.36 lab tons hauv 2018; Rutile tau tsim nyob rau hauv Australia, Sierra Leone, South Africa, Ukraine, thiab lwm yam, nrog rau tag nrho ntawm 750000 tons nyob rau hauv 2018. Cov loj tshaj exporters yog South Africa, Australia, Canada, Mozambique thiab India, uas muab rau lub tebchaws United States, Nyiv. , Tuam Tshoj thiab lub teb chaws Yelemees. Sab nraud dependence yog hais txog qhov sib piv ntawm net ntshuam ntim ntawm ib yam khoom rau nws tag nrho noj. Kev vam khom sab nraud ntawm cov khoom siv ntxhia tuaj yeem qhia tau tias qee yam ntxhia nyob ntawm kev lag luam thoob ntiaj teb, muab cov ntaub ntawv rau tsoomfwv los tsim cov cai ntawm kev tsim thiab siv cov ntxhia, uas yog ib qho tseem ceeb qhia txog kev ruaj ntseg.
Cui Rongguo, Wang Lei, Zhu Yuzhu et al. tau suav cov dependence sab nraud ntawm cov khoom ntxhia hauv tsev. Yao Zhen et al. tau txheeb xyuas cov ntaub ntawv ntshuam thiab xa tawm ntawm titanium ore los ntawm Nonferrous Metals Industry Association thiab Tuam Tshoj Customs. Nws tau ntseeg tias Tuam Tshoj txoj kev vam meej tag nrho ntawm titanium ore yog nce. Tom qab kev soj ntsuam cov ntshuam thiab xa tawm ntawm titanium ore thiab nws cov khoom siv hauv tsev, tag nrho cov khoom siv suav nrog cov khoom xa tawm thiab cov khoom siv hauv tsev. Raws li Cui Rongguo tus qauv tsom xam, peb suav cov kev hloov pauv hauv Suav teb sab nraud dependence rau titanium ore.
2009 txog tam sim no tau pom kev loj hlob ntawm titanium ore hauv Suav teb. Los ntawm 2009 mus rau 2012, cov ntshuam tau nce los ntawm 1.479 lab tons mus rau 2.905 lab tons, nyob rau hauv ib tug ceev upward trend; Tom qab xyoo 2012, net ntshuam tau poob qis hauv kev poob qis ntawm kev lag luam mining thoob ntiaj teb. Nyob rau hauv 2015, cov ntshuam tau txo mus rau 1.88 lab tons, 35.3% tsawg tshaj li ntawm 2012. Lub sab nraud dependence ntawm titanium ore khoom tau nce los ntawm qis tshaj 14.8% nyob rau hauv 2011 mus rau 84.2% nyob rau hauv 2015, ze li ntawm 70%. Tam sim no, Tuam Tshoj sab nraud dependence ntawm titanium ore khoom yog 63.8%. Raws li Cui Rongguo txoj kev xav, nws yog theem nrab nruab nrab. Tsoom fwv yuav tsum tau siv zog ntsuas los tsim cov cai rau kev tsim cov pob zeb hauv av, txhawm rau kom ua tiav cov txiaj ntsig sai li sai tau.
