Indonesia's Harita Nickel tab tom nthuav dav nws cov haujlwm, raws li xov xwm tawm txawv teb chaws. Lub tuam txhab kev sib xyaw nickel mining thiab downstream lub tuam txhab tau pib ua haujlwm ntawm nws qhov thib ob HPAL (hydroxide nag lossis daus) cog thiab npaj yuav nthuav dav nws cov RKEF (rotary kiln electric furnace) cov kab ntau lawm los ntawm kev sib xyaw nrog PT Karunia Permai Sentosa (KPS).
Kev tsim kho ua haujlwm ntawm Harita Nickel qhov thib ob HPAL cog tau nkag siab tias yuav pib ua haujlwm los ntawm nws lub chaw haujlwm PT Obi Nickel Cobalt (ONC). Cov nroj tsuag muaj peev xwm kwv yees li ntawm 65, 000 tonnes ib xyoos twg nrog peb cov kab ntau lawm thiab tau teem sijhawm los ua haujlwm ua haujlwm nyob rau lub quarter thib ob ntawm xyoo 2024.Cov txheej txheem HPAL yog ib txoj hauv kev tsim cov nickel thiab cobalt hlau los ntawm nickel- muaj cov kev daws teeb meem, nrog rau cov kauj ruam tseem ceeb suav nrog kev kho ammiation thiab sulphidation, nrog rau kev siv cov txheej txheem oxidation ntawm huab cua los tsim hydroxide precipitates.
Lub caij no, Harita Nickel tseem npaj yuav koom nrog PT Karunia Permai Sentosa (KPS) los nthuav nws cov kab ntau lawm RKEF. Txoj kev npaj nthuav dav yog npaj los tsim 12 kab nyob rau yav tom ntej, nqa ferronickel muaj peev xwm mus txog 185,000 tonnes ib xyoos twg. Raws li Harita Nickel qhov kev kwv yees, qhov kev nthuav dav yuav tsum pib ua haujlwm nyob rau hauv ib nrab xyoo 2025.Cov txheej txheem RKEF yog lub tshuab hluav taws xob thiab hluav taws xob ua hluav taws xob raws li cov txheej txheem smelting dav siv los tsim cov qib siab nickel alloys xws li ferronickel.
Kev tsim kho ntawm HPAL cog tshiab no thiab kev nthuav dav ntawm kev koom tes nrog KPS yuav ntxiv dag zog rau Harita Nickel cov nickel mining thiab downstream lag luam nyob hauv Indonesia thiab thoob ntiaj teb. Nrog rau kev siv ntawm cov haujlwm no, Harita Nickel yuav tsis tsuas yog ntxiv dag zog rau nws txoj haujlwm kev lag luam hauv Indonesia, tab sis kuj txhim kho nws cov nickel mining thiab downstream khoom muaj peev xwm thoob ntiaj teb.
Rau Harita Nickel, qhov kev siv ntawm cov haujlwm no yuav tsis tsuas yog pab txhim kho cov ntim ntau lawm thiab zoo ntawm nws cov khoom, tab sis kuj pab lub tuam txhab kom hloov tau zoo dua thiab ua tau raws li qhov xav tau ntawm nickel thiab lwm yam khoom lag luam hauv ntiaj teb. Nyob rau tib lub sijhawm, los ntawm kev siv cov haujlwm no, Harita Nickel tseem yuav ua haujlwm los txhawb nws txoj kev tsim kho kev lag luam thiab kev lag luam hauv Indonesia.
