Phakathi kohlengahlengiso lweshishini le-aluminium kwihlabathi liphela, iGuinea ifumene indlela ebalulekileyo yokuxhasa ishishini le-aluminium kwihlabathi liphela.
Ineetoni eziziibhiliyoni ezisi-7.4 zeetoni ze-bauxite ezingasetyenziswayo, i-ore ye-premium ene-silicon ephantsi kunye ne-alumina ephezulu enomxholo we-alumina ongama-45%-62%, kunye neenzuzo zendalo zokungcwaba nzulu kunye nokumbiwa okulula kwemigodi evulekileyo, iGuinea ilawula ngaphezulu kwe-70% yemarike yorhwebo lwe-bauxite yolwandle yehlabathi. Okuphawulekayo kukuba, i-74% ye-bauxite engeniswa eTshayina ivela eGuinea, nto leyo eyenza ukuba ibe yintsika ephambili yokubonelela ngezinto eziluhlaza kwishishini le-aluminium laseTshayina.
Ngokusetyenziswa ngokupheleleyo kweSicwangciso seSizwe saseGuinea iSimandou sika-2040, utyalo-mali olupheleleyo kwiminyaka eli-15 lufikelela kwi-200 yeebhiliyoni zeedola zaseMelika, apho isigaba sokuqala (2025-2030) sifikelele kwi-65 yeebhiliyoni zeedola zaseMelika, nto leyo eguqula ngokupheleleyo ingqiqo yophuhliso lwemizi-mveliso yasekuhlaleni.
Urhulumente waseGuinea ukhuthaze ngamandla imigaqo-nkqubo emitsha yobuzwe bezixhobo. Ngokubuyisela amalungelo okumba angasebenziyo, ukulawula imveliso ukuze kuqiniswe amaxabiso, kunye nokunyanzelisa ukucutshungulwa kwendawo, kuyakuthintela ngokucacileyo ukuthunyelwa kwe-ore ekrwada ngaphandle, kunyanzelisa ukuba i-bauxite icutshungulwe kwindawo ibe yi-alumina, i-aluminium ye-electrolytic kunye neengots ze-aluminium.
Amashishini aphambili aseTshayina aquka i-Aluminium Corporation yaseTshayina (CHINALCO), i-SMB Winning Consortium kunye ne-SPIC zikhokele kuyilo, ziqalise iiprojekthi ze-alumina ezivelisa i-1.2 yezigidi zeetoni ngonyaka emva kwenye, kwaye ziqalise lonke uthotho lwemizi-mveliso olujolise ekufumaneni indawo ye-"bauxite — alumina — electrolytic aluminum — aluminium ingot". IGuinea itshintsha ngokukhawuleza ukusuka ekuthumeleni i-ore enye ngaphandle ibe sisiseko sokuvelisa i-aluminium eAfrika.
Ngokwembono ye-industrial conversion logic, yakuba i-bauxite inyibilikisiwe ibe yi-alumina, ukufaka yonke imithamo kwimveliso ye-aluminium ye-electrolytic kuya kwenza umlinganiselo omkhulu kwi-industrial.
Ngokwezibalo zethiyori yemizi-mveliso, iitoni ezili-1.2 lezigidi ze-alumina zinokuvelisa malunga neetoni ezingama-635,300 ze-aluminium ye-electrolytic ngokwethiyori. Emva kokunciphisa ilahleko ye-electrolysis yemizi-mveliso kunye nelahleko yokutsha kwe-casting, imveliso ezinzileyo yee-ingots ze-aluminium ifikelela kwiitoni ezingama-610,000 ukuya kuma-615,000.
Umgca wemveliso ye-aluminium ingot ovelisa iitoni ezingama-600,000 ngonyaka kufuneka utye malunga neetoni ezingama-300,000 zee-anode ezibhakiweyo kwangaphambili kunye neetoni ezili-15,000 zeebhloko zekhabhoni ze-cathode minyaka le. Njengenxalenye ephambili esetyenziswayo nebalulekileyo kwimveliso ye-aluminium ye-electrolytic, amandla okubonelela kunye nolawulo lomgangatho wee-anode ezibhakiweyo kwangaphambili zimisela ngokuthe ngqo ukusebenza okuzinzileyo, ukunciphisa iindleko kunye nokuphuculwa kokusebenza kakuhle kweeprojekthi ze-aluminium ze-electrolytic zasekuhlaleni eGuinea.
Kwinkqubo yokuvelisa ii-anode ezibhakiweyo kwangaphambili, inkqubo yokuxova nokwakha eshushu sisixhobo esibalulekileyo, esigubungela yonke inkqubo yokulinganisa izinto ezomileyo, ukuxova ubushushu obungaguqukiyo, ukuguqulwa kwentlama kunye nokwenza ukungcangcazela.
Isebenza kakhulu ekudibaniseni ii-carbon aggregates ezifana ne-petroleum coke kunye ne-pitch coke kunye ne-pitch binder, ukugqiba ukusika, ukuxova kunye nokudibanisa ukungena phantsi kolawulo lobushushu oluchanekileyo ukwenza i-homogeneous plastic paste, ethi emva koko yenziwe ngokuchanekileyo ibe ziibhloko ze-anode eziqhelekileyo.
Ukuchaneka kwenkqubo yokuxova nokwenza kuchaphazela ngokuthe ngqo uxinano olukhulu, ukuhanjiswa kombane kunye namandla oomatshini ee-anode, kwaye kuchaphazela ngakumbi ukusetyenziswa kwamandla, ukusebenza kakuhle kwangoku kunye nezinga lokufaneleka kwemveliso yemveliso ye-aluminium ye-electrolytic, esebenza njengesiqinisekiso esisisiseko sokusebenza kakuhle nangokungasebenzisi kakhulu kwemigca yemveliso ye-aluminium ye-electrolytic.
Okwangoku, iGuinea ijongene neziphene eziphawulekayo kwizibonelelo zokuxhasa ishishini layo le-aluminium lasekuhlaleni. Nangona amandla e-alumina kunye ne-electrolytic aluminium esetyenziswa ngesantya esikhawulezileyo, amandla okuxhasa afana ne-anodes ezibhakiweyo kwangaphambili kunye neebhloko ze-cathode carbon azanelanga kakhulu, kwaye amacandelo axhasayo e-industrial chain aquka izinto ezingafunekiyo, izixhobo ze-caustic soda kunye ne-carbon forming azinanto.
Ngokutyikitywa nokusungulwa ngokusesikweni kweprojekthi ye-alumina ye-CHINALCO eyi-1.2 yezigidi zeetoni, kunye nokwakhiwa ngokukhawuleza kweeprojekthi ze-alumina ze-SMB kunye ne-SPIC, inani elikhulu lemigca yemveliso ye-aluminium ye-electrolytic iya kuqaliswa ngamandla, nto leyo eza kubangela imfuno enkulu yeenkqubo zokuxova nokwenza ezisebenza kakuhle nezinkulu.
Ijolise kwimfuno yophuhliso lweshishini le-aluminium elikwindawo yaseGuinea, inkqubo yobungcali yokuxova nokwakha inezinto ezininzi eziluncedo ezifana nokuzivumelanisa nomthamo omkhulu, ukonga umbane kunye nokunciphisa ukusetyenziswa, umgangatho ozinzileyo kunye nokuhambelana nokusebenza kunye nokugcinwa kweendawo zangaphandle.
I-HWAPENGInkqubo yokuFudumeza nokuQoba esebenza kakuhle kakhulukwayeInkqubo yokwenza i-HP-EVC800 Extrusion VibrocompactorUkwamkela iteknoloji yokulawula ubushushu echanekileyo kunye nempazamo yokulinganisa ubushushu elawulwa ngaphakathi kwe-±2℃, izixhobo zinokusebenza ngokuzinzileyo kokufudumeza izinto ezomileyo, ukuxova ngamandla aphezulu kunye nokwenza ukupholisa;
Inganyusa ngempumelelo izinga lemveliso egqityiweyo ye-anode nge-2%-5%, inciphise ukusetyenziswa kwepitch ngaphezulu kwe-2%, inyuse uxinano lwe-bulk olubunjiweyo ngeeyunithi ze-0.02, kwaye inciphise kakhulu ilahleko yemveliso ye-electrolysis kunye neendleko zokusebenza.
Okwangoku, uyilo lwemodyuli luyaziqhelanisa nokufakelwa kunye nokuqaliswa kweeprojekthi zaphesheya, kwaye isakhiwo esivaliweyo sithintela ukuvuza kothuli kunye nomsi wepitch, sithobela imigaqo yokhuseleko lokusingqongileyo yaseGuinea kwaye sihlangabezana ngokugqibeleleyo nemfuno exhasayo yeebhloko ze-anode carbon zemigca yemveliso ye-aluminium ingot enemveliso yonyaka yeetoni ezingama-600,000 nangaphezulu.
Ukujonga phambili, kuqhutywa yimigaqo-nkqubo yaseGuinea kunye noyilo olupheleleyo lweshishini lamashishini aseTshayina, ukucutshungulwa okunzulu kwe-bauxite kwindawo yasekuhlaleni kuye kwaba ngumkhwa ongenakuguqulwa, kwaye amandla e-aluminium ye-electrolytic kunye nee-ingots ze-aluminium aya kuqhubeka nokukhula.
Njengezixhobo eziphambili zokuvelisa i-anode ebhakiweyo kwangaphambili, inkqubo yokuxova nokwakha ngaphambi kokufudumeza iya kuzalisa umsantsa oxhasayo kwishishini le-aluminium laseGuinea, ibe yindawo ephambili yokungena ekucwangciseni umkhondo weshishini le-aluminium laseAfrika kwaye yabelane ngezabelo zokucubungula okwenziwe kwindawo, kwaye incede amashishini aseTshayina ukuba aphucule umda ovaliweyo wecandelo lonke lemizi-mveliso "yezixhobo + iziseko zophuhliso + ukucubungula + izibonelelo ezixhasayo", iphonononga ngakumbi imakethi yolwandle oluluhlaza okwesibhakabhaka yeshishini le-aluminium eGuinea.
