Mining: tatauranga

Te ahumahi keri hou, pehea tata rawa kaha nui haere te ahumahi ngā, tona mana i runga i te ōhanga ao. I te kau, e te reira 5 wahi i roto i te rangatira o te wāhi ahumahi nui rawa, aru e te rorohiko, ho'oraa, te hinu me te hau me te rängai pēke. ahumahi keri Russian ko tetahi o te nui rawa, me te kua he pānga nui i runga i te whanaketanga o tenei rohe rite te katoa.

I tēnei rāngai ngā he plurality o ngā tipu iti e kawe i roto i te tangohanga o ngā kohuke (paru, Mika, papa kiripaka, graphite, pāhare pāporo mara hopi, kotakota, taimana, waro, konukarihi ore, ore rino, te konganuku rangatira, me te turanga, me ngā rauemi kohuke ngā hanga). Extraction o hau pā ana hoki me te hinu i roto i nuinga o te wā ki te ahumahi keri. Ko te whanaketanga ko e rua raro (maina) me tuwhera (mahi) ara.

Neke atu i te te 6 tau mua kua ara te ahumahi keri i wahi 24 ki te 5 i roto i te ahumahi ārahi i roto i te ao. Kei te kamupene nui nui pūmau i roto i te tūranga ārahi i roto i te ōhanga ao (Rio Tinto, Vale).

Ki te rā, kore whenua kua te katoa rōrahi o ngā momo katoa i roto i te ao o ngā toka me ngā kohuke. Anake 10 o ratou, e te hunga kau taki i roto i te maha o te matatoka kawemai, taea ki te pā ana ki 35 momo o ngā hua kohuke hua he. I roto ia ratou, Canada, Awherika ki te Tonga, India, Brazil, Ahitereiria, USA, China ko Russia. Heoi, ko te kohi o te kaiārahi mau ahumahi production pupuri China.

I roto i nga whenua o te "taha" o te ahumahi keri ko e pā ana ki 2.5% o te tapeke hanga mo te whenua ake whakawhanakehia pae tenei ahua i te 12 ki te 16 ōrau. O nga whenua Pākehā, Denmark anake, te Netherlands, Norway me Bulgaria te pai whakawhanakehia, te ahumahi.

Chile, Russia, Ahitereiria, Āwherika ki te Tonga me te Canada hanga ake te runga kau taki e rima ao i roto i te ahumahi keri. Na kua nui haere nuinga te tūranga o te rāngai i roto i enei ōhanga i roto i nga tau tata nei, me te pūkete hoki e pā ana ki 15%.

Rino ore, parahi, waro - rauemi māori, e tika ana ki nei te whenua whakawhanakehia ko te moni te nuinga, pūkete ratou hoki e pā ana ki 65%.

I te tau 2011 ka nui haere te ahumahi keri ao tona production i 6%.

Ka karanga te āhua o ngā take o nāianei i roto i te ahumahi keri ao e taea e te tīmatanga o te "wā hou" pera-ka karanga. Ko, kāore, i reira e etahi onäianei: hua utu nui haere tika ki te kore o kaimahi mohio, he mea e tika ana ki te whakawhanake i te mara ki te makona ratou iti, me te iti-kounga rakau, te hoahoa he tonu maina utu, mai i te wahi o te hanga e matatini ake me e kei tata i nga pa nui .

Ka rite ki te hua, ka taea e tatou he pakari te mea e te ahumahi keri o te ao, ko te tino ti'aturi i runga i nga mahi o whenua whakawhanake (te nuinga China rite te kiritaki nui o ngā hua o te ahumahi). He hua nui i roto i te tono meinga te pororaru, Brazil, Indonesia, India. mahara hoki e pā ana ki te meka i tutuki te United States i te ora o tona ake ōhanga, me te tonu toe tetahi o nga kiritaki nui rawa. te raraunga i runga ake katoa homai tumanako mo pūmautanga o te ōhanga ao i roto i te mara o te keri, engari ko reira tonu te mōrea. I te kau, kia whiriwhiri te hoko o ngā rawa ngā ki te hanga i to koutou ake. Heoi, hoki he tino atu pai, me te ohie o te kamupene keri ki te whakaaro pai ake huarahi ki te whakapai ake i te taonga Karapa hei utu o te hanga i te hou rawa.
