E ai ki te pūrongo a te US Geological Survey (2014), ko te nui o ngā rawa kua whakamātauhia o te karāpeti maori o te ao he 130 miriona tana, ā, ko Brazil he 58 miriona tana o aua rawa, ā, ko Haina he 55 miriona tana o aua rawa, koia tētahi o ngā mea tino pai o te ao. I tēnei rā, ka kōrero atu te ētita o Furuite Graphite ki a koe mō te tohatoha o ngā rawa karāpeti maori o te ao:
Ahakoa kua kitea e te tini o ngā whenua ngā kohuke o te karāpeti maramara puta noa i te ao, kāore i te maha ngā putunga o te karāpeti maramara mō te whakamahinga ahumahi, ko te nuinga kei Haina, Brazil, Īnia, Czech Republic, Mexico me ētahi atu whenua.
1. Haina
E ai ki ngā tatauranga a te Manatū Whenua me ngā Rauemi, tae noa ki te mutunga o te tau 2014, ko te nui o ngā rahui o te konganuku karāpeti tioata o Haina he 20 miriona tana, ā, ko ngā rahui rauemi kua tautuhia he tata ki te 220 miriona tana, e horahia ana i roto i ngā kawanatanga 20 me ngā rohe motuhake pērā i a Heilongjiang, Shandong, Mongolia o Roto me Sichuan, ā, ko Shandong me Heilongjiang ngā rohe whakaputa matua. Ko ngā rahui o te karāpeti tioata i Haina he tata ki te 5 miriona tana, ā, ko ngā rahui rauemi kua whakamātauhia he tata ki te 35 miriona tana, e horahia ana i roto i ngā kawanatanga 9 me ngā rohe motuhake tae atu ki a Hunan, Mongolia o Roto me Jilin. I roto i ēnei, ko Chenzhou, Hunan te wāhi e kukū ai te karāpeti tioata.
2. Parahi
E ai ki ngā tatauranga a te US Geological Survey, ko ngā rahui o te konganuku karāpiti i Brazil e tata ana ki te 58 miriona tana, ā, ko ngā rahui karāpiti maori he nui ake i te 36 miriona tana. Ko ngā putunga karāpiti i Brazil kei Minas Gerais me Bahia te nuinga, ā, ko ngā putunga karāpiti maori pai rawa atu kei Minas Gerais.
3. Īnia
E 11 miriona tana ngā rahui karāpeti o Īnia, ā, e 158 miriona tana ngā rauemi. E toru ngā whitiki maina karāpeti, ā, ko ngā maina karāpeti he uara whanaketanga ōhanga kei te nuinga o te wā kei Andhra Pradesh me Orissa.
4. Te Repupiripia o Tīki
Ko te Czech Republic te whenua he nui rawa ngā rauemi karāpeti maramara i Ūropi. Ko te nuinga o ngā putunga karāpeti maramara kei te Tonga o Czech Republic. Ko ngā putunga karāpeti maramara i te rohe o Moravia me te ihirangi waro pumau o te 15% he karāpeti moroiti te nuinga, ā, ko te ihirangi waro pumau he tata ki te 35%.
5. Mehiko
Ko ngā maina karāpeti maramara kua kitea i Mexico he karāpeti moroiti katoa, ā, ko te nuinga kei Sonora me Oaxaca. Ko te karāpeti maramara maramara o Hermosillo kua whakawhanakehia he 65% ki te 85%.
