I waenganui i te hanganga anō o te mekameka tuku ahumahi konumohe o te ao, kua mau pūmau a Guinea ki te pūtake o te umanga konumohe o te ao.
E 7.4 piriona tāne o ngā rahui bauxite ka taea te whakamahi, he iti te hiraka me te nui te alumina kounga teitei me te ihirangi alumina o te 45%-62%, tae atu ki ngā painga taiao o te tanumanga papaku me te ngawari o te keri tuwhera, ko Guinea te rangatira o te 70% o te mākete hokohoko bauxite moana o te ao. He mea nui, 74% o te bauxite kawemai a Haina i ahu mai i Guinea, ka waiho hei pou matua mo te tuku rauemi mata mo te umanga konumohe o Haina.
I te whakatinanatanga katoa o te Mahere ā-Motu o Simandou 2040 o Guinea, ka eke te haumitanga katoa mō ngā tau 15 ki te 200 piriona tāra US, ā, ko te wāhanga tuatahi (2025-2030) ka eke ki te 65 piriona tāra US, ka huri katoa i te kaupapa o te whanaketanga ahumahi ā-rohe.
Kua kaha te whakatairanga a te kāwanatanga o Guinea i ngā kaupapa here hou mō te whenua rauemi. Mā te whakahoki mai i ngā mana keri kore mahi, te whakahaere i ngā putanga hei whakaū i ngā utu, me te whakamana i te tukatuka ā-rohe, ka āraia te kaweake noa i te konganuku mata, me te akiaki i te tukatuka ā-rohe i te bauxite hei alumina, te konumohe hiko me ngā poro konumohe.
Ko ngā umanga matua o Haina, tae atu ki te Aluminium Corporation of China（CHINALCO）, SMB Winning Consortium me SPIC, kua ārahi i te tahora, me te whakarewa i ngā kaupapa alumina whakaputa 1.2 miriona tana ia tau, tētahi i muri i tētahi, me te tīmata i te mekameka ahumahi katoa o te "bauxite — alumina — konumohe hiko — ingot konumohe". Kei te tere te huri o Guinea mai i te kaweake konganuku kotahi ki te turanga hanga konumohe matua i Āwherika.
Mai i te tirohanga a te ariā hurihanga ahumahi, ina whakarewaina te bauxite hei alumina, mā te whakapau i tōna kaha katoa ki te hanga konumohe hiko ka puta he tauine ahumahi nui.
E ai ki te tātaitanga ariā ahumahi, ka taea e te 1.2 miriona tana o te alumina te whakaputa i te 635,300 tana o te konumohe hikohiko. I muri i te tango i te ngaronga hikohiko ahumahi me te ngaronga tahunga whakarewa, ka eke te putanga pumau o ngā ingota konumohe ki te 610,000 ki te 615,000 tana.
Me pau te 300,000 tāne o ngā anode kua tunua i mua me te 15,000 tāne o ngā poraka waro katote i ia tau mō tētahi raina whakaputa ingota konumohe, ā, ko tana putanga ā-tau he 600,000 tāne. Hei wāhanga matua me te wāhanga matua o te whakaputa konumohe hikohiko, ko te kaha tuku me te whakahaere kounga o ngā anode kua tunua i mua te mea e whakatau tika ana i te mahi pumau, te whakaiti utu me te whakapai ake i te whai huatanga o ngā kaupapa konumohe hikohiko ā-rohe i Guinea.
I roto i te tukanga whakaputa o ngā anode kua tunua i mua, he taputapu matua nui te pūnaha pokepoke me te hanga whakamahana-mua, e kapi ana i te tukanga katoa o te whakataurite rauemi maroke, te pokepoke pāmahana pumau, te whakarerekētanga whakapiri me te hanga wiri.
Ko tāna mahi matua he whakaranu i ngā konganuku waro pēnei i te petroleum coke me te pitch coke me te here pitch, ka oti te kutikuti, te pokepoke me te whakakotahitanga whakauru i raro i te mana whakahaere pāmahana tika hei hanga i te whakapiri kirihou ōrite, ka hangaia kia tika hei poraka anode paerewa.
Ka pā tika te tika o te tukanga pokepoke me te hanga ki te matotoru papatipu, te kawe hiko me te kaha ā-pūkaha o ngā anode, ā, ka pā anō hoki ki te whakapaunga pūngao, te whai huatanga o te au me te tere tohu hua o te hanga konumohe hiko, hei taurangi matua mō te mahi whai hua me te iti o te whakapaunga o ngā raina hanga konumohe hiko.
I tēnei wā, kei te pāngia a Guinea e ngā ngoikoretanga nui i roto i ngā whakaurunga tautoko mō tana umanga konumohe ā-rohe. Ahakoa kei te tere haere te whakatinanatanga o ngā kaha konumohe alumina me te konumohe hikohiko, kāore i te rawaka ngā kaha tautoko pēnei i ngā anode kua tunua mua me ngā poraka waro cathode, ā, tata korekore noa iho ngā rāngai tautoko mekameka ahumahi tae atu ki ngā rauemi ātete ahi, te houra kaustic me ngā taputapu hanga waro.
I te hainatanga mana me te whakarewatanga o te kaupapa alumina 1.2 miriona tana a CHINALCO, me te tere o te hanganga o ngā kaupapa alumina a SMB me SPIC, ka whakarewahia he maha o ngā raina whakaputa konumohe hikohiko, ka piki ake te hiahia mō ngā pūnaha pokepoke me te hanga mahi-teitei me te tauine nui.
E aro ana ki te whanaketanga o te umanga konumohe ā-rohe o Guinea, he maha ngā painga matua o te pūnaha pokepoke me te hanga whakamahana ngaio pēnei i te urutau ki te kaha nui, te penapena me te whakaiti i te kai pūngao, te kounga pumau me te hototahi ki te whakahaere me te tiaki ā-rohe o tāwāhi.
HWAPENGPūnaha Whakamahana me te Pokepoke Tino PaimePūnaha hanga HP-EVC800 Extrusion VibrocompactorMā te whakamahi i te hangarau whakahaere pāmahana tika me te hapa ine pāmahana e whakahaeretia ana i roto i te ±2 ℃, ka taea e te taputapu te whakatutuki i te mahi whakauru o te whakamahana rauemi maroke, te pokepoke kaha-teitei me te hanga whakamatao;
Ka taea e ia te whakanui ake i te tere o te hua oti o te anode mā te 2%-5%, te whakaiti i te whakamahinga o te pitch mā te neke atu i te 2%, te whakanui ake i te kiato papatipu i hangaia mā te 0.02 waeine, ā, ka tino whakaiti i te ngaronga whakaputa hiko me ngā utu whakahaere.
I taua wā tonu, ka urutau te hoahoa ā-pūrere ki te tāutanga me te whakatinanatanga o ngā kaupapa o tāwāhi, ā, ka ārai te hanganga hiri i te turuturu o te puehu me te paoa o te ware pi, e tutuki ana i ngā ture tiaki taiao o Guinea, ā, e tino tutuki ana hoki i te tono tautoko mō ngā poraka waro anode o ngā raina whakaputa ingot konumohe me te putanga ā-tau o te 600,000 tana me runga ake.
I te tirohanga whakamua, i raro i ngā kaupapa here a Guinea me te whakatakotoranga mekameka ahumahi katoa o ngā umanga Hainamana, kua noho te tukatuka hohonu o te bauxite ā-rohe hei ia āhua e kore e taea te whakakore, ā, ka haere tonu te whānui o te kaha o ngā konganuku konumohe hiko me ngā konganuku konumohe.
Hei taputapu matua mō te hanga anode kua tunua i mua, ka whakakīia e te pūnaha pokepoke me te hanga whakamahana te āputa tautoko o te umanga konumohe o Guinea, ka noho hei wāhi tomokanga matua ki te whakatakoto i te ara umanga konumohe o Awherika me te tohatoha i ngā hua o te tukatuka ā-rohe, ā, ka āwhina i ngā umanga Haina ki te whakapai ake i te porowhita kati o te mekameka ahumahi katoa o "ngā rauemi + hanganga + tukatuka + ngā whakaurunga tautoko", me te tūhura atu i te mākete moana kikorangi taumata-tiriona o te umanga konumohe i Guinea.
