Pakati pekugadziriswazve kweindasitiri yepasi rose yearuminiyamu, Guinea yave kunzwisisa zvizere indasitiri yepasi rose yearuminiyamu.
Yakashongedzwa nematani mabhiriyoni manomwe nemazana mana emabhaudhi emvura inocherwa nebauxite, ine simbi shoma uye ine alumina yakawanda ine alumina ye45%-62%, pamwe chete nemabhenefiti echisikigo ekuviga matombo asina kudzika uye kuchera matombo ari nyore, Guinea inotonga pamusoro pe70% yemusika wepasi rose webhauxite yegungwa. Zvakakosha kuti, 74% yebhauxite inotengwa kunze kwenyika yeChina inobva kuGuinea, zvichiita kuti ive musimboti wezvinhu zvakagadzirwa neindasitiri yealuminium yeChina.
Nekuitwa kwakazara kweSimandou 2040 National Plan yeGuinea, mari yese yaiswa mumakore gumi nemashanu inosvika mabhiriyoni mazana maviri emadhora ekuAmerica, nechikamu chekutanga (2025-2030) chakasvika mabhiriyoni makumi matanhatu nemashanu emadhora ekuAmerica, zvichichinja zvachose pfungwa yekuvandudzwa kwemaindasitiri emuno.
Hurumende yeGuinea yakasimudzira zvakasimba mitemo mitsva yerudzi rwezviwanikwa. Nekudzoreredza kodzero dzekuchera dzisina basa, kudzora zvinobuda kuti mitengo igare yakamira, uye kusimbisa kugadziriswa kwenzvimbo, zvinorambidza pachena kutengeswa kwematombo asina kucheneswa kunze kwenyika, zvichimanikidza bauxite kuti igadzirwe munzvimbo iyi kuita alumina, electrolytic aluminum uye aluminium ingots.
Makambani makuru ekuChina anosanganisira Aluminum Corporation of China (CHINALCO), SMB Winning Consortium neSPIC vakatungamira mukuronga, vachitanga mapurojekiti egore negore ealumina anokwana matani mamiriyoni 1.2 rimwe nerimwe, uye vachitanga kushandiswa kwe "bauxite — alumina — electrolytic aluminum — aluminium ingot" mumaindasitiri. Guinea iri kuchinja nekukurumidza kubva pakutengesa ore imwe chete kuenda kukambani huru yekugadzira aluminum muAfrica.
Kubva pamaonero ekushandura maindasitiri, kana bauxite yanyungudutswa kuita alumina, kuisa simba rese mukugadzirwa kwearuminiyamu yemagetsi kuchaumba huwandu hukuru hwemaindasitiri.
Zvichienderana nekuverenga kwenyanzvi dzezvemaindasitiri, matani mamiriyoni 1.2 ealumina anogona kugadzira matani angangoita 635,300 ealuminamu. Mushure mekubvisa kurasikirwa kwemagetsi emuindasitiri uye kurasikirwa nekupisa, kubuda kwakasimba kwealuminamu ingots kunosvika matani 610,000 kusvika 615,000.
Mutsetse wekugadzira aluminium ingot une simba rekugadzira matani 600,000 pagore unofanirwa kushandisa matani angangoita 300,000 eanode dzakabikwa kare uye matani 15,000 e cathode carbon blocks gore rega rega. Sechinhu chikuru chinoshandiswa uye chakakosha pakugadzirwa kwe electrolytic aluminum, kugona kwekugovera uye kutonga kwemhando yeanode dzakabikwa kare zvinosarudza zvakananga kushanda kwakasimba, kudzikisa mitengo uye kuvandudzwa kwekushanda zvakanaka kwemapurojekiti e electrolytic aluminum emuno muGuinea.
Mukugadzirwa kwema anode akabikwa kare, sisitimu yekukanya nekuumba chinhu chakakosha, chinosanganisira maitiro ese ekuyera zvinhu zvakaoma, kukanya tembiricha nguva dzose, kugadzirisa paste uye kugadzira vibration.
Inonyanya kushanda pakusanganisa zvinhu zvakaita sepetroleum coke nepitch coke nepitch binder, kupedzisa kucheka, kukanya uye kupinda mukati mechinhu pasi pekudzora tembiricha chaiyo kuti pave nepurasitiki yakafanana, iyo inobva yagadzirwa nemazvo kuita mabhuroko eanode akajairwa.
Kurongeka kwemaitiro ekukanya nekuumba kunokanganisa zvakananga huwandu hwezvinhu, kufambisa magetsi uye simba remakemikari reanode, uye zvinopesvedzera kushandiswa kwesimba, kushanda zvakanaka kwezvino uye mwero wekukodzera kwekugadzirwa kwearuminiyamu yemagetsi, zvichishanda sevimbiso huru yekushanda zvakanaka uye kushoma kwemidziyo yekugadzira aruminiyamu yemagetsi.
Parizvino, Guinea inotarisana nekusakwana kukuru mukutsigira indasitiri yayo yearuminiyamu yemuno. Kunyange hazvo kugona kwearuminiyamu nearuminiyamu yemagetsi kuri kushanda nekukurumidza, kugona kwekutsigira kwakadai seanode dzakabikwa kare uye cathode carbon blocks hakuna kukwana zvakanyanya, uye zvikamu zvekutsigira cheni yemaindasitiri zvinosanganisira zvinhu zvinoramba kushanda, caustic soda uye michina yekugadzira kabhoni hazvina kukwana.
Nekusainirwa uye kutangwa kwechirongwa cheCHINALCO chealumina chemamiriyoni 1.2 ematani, uye kukurumidza kuvaka mapurojekiti ealumina eSMB neSPIC, huwandu hwakawanda hwemitsetse yekugadzira aluminium yemagetsi huchatangwa zvakanyanya, zvichiunza kudiwa kukuru kwemasisitimu ekukanya & kugadzira anoshanda zvakanyanya uye makuru.
Ichitarisa kudiwa kwekugadzirwa kwearuminiyamu muGuinea, sisitimu yehunyanzvi yekudziisa nekuumba ine zvakanakira zvakawanda zvakaita sekugona kuchinjika kune huwandu hukuru, kuchengetedza simba uye kuderedza kushandiswa, mhando yakagadzikana uye inoenderana nekushanda nekugadzirisa kwekunze kwenyika.

Tichitarisa mberi, tichitungamirirwa nemitemo yeGuinea uye marongerwo akazara emaindasitiri emabhizinesi ekuChina, kugadziriswa kwe bauxite kwava tsika isingadzoreki, uye kugona kwe electrolytic aluminum ne aluminium ingots kucharamba kuchikura.
Semichina mikuru yekugadzira anode yakabikwa kare, sisitimu yekukanya & kugadzira ichazadza mukaha unotsigira indasitiri yealuminium yeGuinea, ichava nzvimbo huru yekuisa nzira yeindasitiri yealuminium yeAfrica uye kugovera mibairo yekugadzirisa kwenzvimbo, uye kubatsira mabhizinesi ekuChina kuvandudza denderedzwa rese re "zviwanikwa + zvivakwa + kugadzirisa + nzvimbo dzinotsigira", vachienderera mberi nekutsvaga musika wegungwa rebhuruu weindasitiri yealuminium muGuinea.
