London, Lub Ob Hlis 16th (Argus) - Vim muaj kev cuam tshuam loj heev ntawm nag xob nag cua "Jazani", lub hauv paus tseem ceeb nickel thiab cobalt hauv Madagascar, Ambatovy (Anbaoto), raug yuam kom kaw tag nrho. Lub nag xob nag cua ua rau muaj kev puas tsuaj loj rau cov chaw ua haujlwm nyob rau hauv Tahoasina, thiab lub tuam txhab tab tom ua cov ncauj lus kom ntxaws kev tshuaj xyuas los ntsuas seb qhov chaw puas tsuaj. Lub tuam txhab tau hais tias kev tsim khoom tsuas yog rov pib dua tom qab lees paub tias cov qauv cog tsis zoo, cov xwm txheej kev nyab xeeb tau ntsib, thiab kev pheej hmoo ib puag ncig yog tswj tau.
Tahoasina yog qhov chaw nres nkoj tseem ceeb ntawm Madagascar thiab tseem yog lub chaw xa tawm rau cov khoom nickel thiab cobalt. Cov nag xob nag cua no ua rau muaj kev puas tsuaj loj rau qhov chaw nres nkoj thiab tuaj yeem cuam tshuam kev thauj mus los, ua rau qeeb ntawm kev xa tawm ntawm cov khoom nruab nrab xws li taum nickel. Cov tub luam tau taw qhia tias yog tias qhov kev kaw cia ntev ntev, nws yuav ua kom nruj ntxiv rau cov khoom siv raw khoom siv los tsim cov roj teeb - qib nickel thiab cobalt sulfates.
Ambatovy yog koom ua ke los ntawm Nyiv Sumitomo thiab South Kauslim KOMIR thiab yog ib qho tseem ceeb refining intermediate tsum, tsis suav nrog Indonesia thiab Democratic Republic of the Congo. Lub mine xav tias yuav tsim tau kwv yees li 28,000 tons ntawm npib tsib xee thiab 2,500 tons ntawm cobalt hauv 2024, thiab nws cov nickel tso tawm hauv lub quarter thib peb ntawm 2025 yuav ncav cuag kwv yees li 9,000 tons, nce li ntawm 25% piv rau lub quarter dhau los. Nws cov khoom siv tsuas yog siv hauv cov ntawv thov xws li cov khoom siv hluav taws xob tsheb hluav taws xob thiab ua lub luag haujlwm tseem ceeb hauv lub ntiaj teb cov roj teeb khoom siv.
Cov kws tshaj lij kev lag luam ntseeg tias qhov kev tshwm sim no tuaj yeem txhawb nqa tus nqi cobalt, thaum muaj kev cuam tshuam tsis zoo rau kev ua lag luam npib tsib xee, raws li Indonesia tau tswj hwm cov khoom siv nickel. Ambatovy tau hais tias tam sim no lub tuam txhab tab tom tsom rau kev ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov zej zog thiab tsim cov phiaj xwm rov qab los, tab sis tsis tau nthuav tawm lub sijhawm tshwj xeeb ntawm kev kaw lossis cuam tshuam rau kev xa tawm.
