Nickel yog ib qho tseem ceeb nonferrous hlau nrog ntau yam kev siv.Nws feem ntau tshwm sim hauv nickel sulfide thiab nickel oxide ores nyob rau hauv cov xwm.30% ntawm cov khoom siv nickel yog sulfide ores thiab 70% yog cov npib tsib xee ore.Nrog rau qhov kev thov ntau ntxiv rau npib tsib xee thiab maj mam depletion ntawm npib tsib xee sulfide ore, txoj kev loj hlob ntawm latex npib tsib xee ore qhia tau hais tias muaj zog heev.Nyob rau hauv cov txheej txheem ntawm sulfuric acid decomposition ntawm laterite npib tsib xee ore, cov pov tseg residue ntawm laterite nickel ore tau dhau los ua ib qho tseem ceeb txwv tsis pub ntub dej nickel extraction txheej txheem.Raws li ib tug manufacturers ntawmnpib tsib xee slagntsug sib tsoo zeb, HCMilling (Guilin Hongcheng) yuav qhia txog cov txheej txheem ntawm kev rov qab thiab rov qab siv cov kua nplaum tom qab nickel ore khib nyiab slag rau koj hauv qab no.

Cov txheej txheem ntawm kev rov qab thiab rov qab siv dua tom qab nickel ore khib nyiab residue yog calcine lateritic nickel ore khib nyiab ntawm 160 ~ 900 ℃ rau 20 ~ 120 min, thiab tom qab ntuj txias, zom nws rau hauv cov khoom siv hmoov nrog 0.08 hli sieve residue tsawg dua 10% dhau npib tsib xee slagntsug sib tsoo zeblos npaj cov khoom siv raw ntawm magnesium cement, txoj hauv kev kho cov khoom siv los yog lub tsev pleev xim rau phab ntsa.Cov kauj ruam tshwj xeeb rau kev rov qab los thiab rov qab siv cov xuab zeb nickel ore slag yog raws li hauv qab no:

(1) Cov nickel slag nrog cov dej noo ntawm 12% ~ 18% (cov khoom zoo hauv qab 3 hli tus account rau ntau tshaj 70%, thiab cov viscosity muaj zog) yog qhuav los ntawm lub tshuab ziab khaub ncaws sai, cov ntsiab lus noo noo yog txo kom tsawg dua. 3%, thiab tom qab ntawd nws muab tso rau hauv qhov chaw cia tom qab kev kho mob tshem tawm cov hlau ntau, thiab cov khoom xyaw muab tso rau hauvnpib tsib xee slagsib tsoo zeb.

(2) Cov nickel slag qhuav yog pub rau hauv nickel slag zeb rau extrusion thiab crushing tom qab batching (ntxiv ib tug tsim nyog tus nqi ntawm activator), thiab ces sib cais los ntawm huab cua sib cais.Cov coarse hais yog rov qab mus rau lubnpib tsib xee slagntsugcov menyuamzeb, thiab cov hmoov zoo ntxiv nkag mus rau hauv cov hmoov concentrator nrog cua los npaj cov khoom tiav, uas yog muab tso rau hauv cia.Cov hmoov ntxhib nrog rau thaj chaw tshwj xeeb ntawm <200m2 / kg yog xa rov qab mus rau nickel slag ntsug sib tsoo zeb thiab tom qab ntawd crushed.Qee cov hmoov zoo tshaj plaws nrog thaj chaw tshwj xeeb ntawm> 450m2 / kg yog sau los ntawm cov khoom siv plua plav thiab xa ncaj qha mus rau lub tsev muag khoom tiav.

Lateite nickel ore khib nyiab slag yog qhov sib xyaw ntawm calcium sulfate, magnesium hydroxide, calcium silicate hydrate thiab calcium aluminate hydrate.Tom qab ziab los yog tsis kub calcination, sib tov ntawm anhydrous calcium sulfate, magnesium oxide, dicalcium silicate thiab calcium aluminate yog tau.Nws muaj cov yam ntxwv ntawm Portland cement, magnesite cement thiab gypsum.Nws yog ib yam tshiab ntawm cov khoom siv cementitious thiab tau siv dav hauv kev tsim kho kev lag luam.Cov txheej txheem rov qab thiab rov siv dua ntawm cov xuab zeb nickel ore khib nyiab slag yog qhov yooj yim, tsis muaj qhov kub thiab txias, siab siab thiab cov ntaub ntawv kim, thiab yooj yim rau kev siv.Cov txheej txheem ntawmnpib tsib xee slagntsugcov menyuamzebyog cov kauj ruam tseem ceeb tshaj plaws hauv kev rov qab los, rov siv dua thiab siv cov peev txheej ntawm cov xuab zeb npib tsib xee slag, suav txog li ib nrab ntawm tag nrho cov kev siv hluav taws xob, txhawm rau txo cov nqi tsim khoom, kev siv hluav taws xob thiab txhim kho kev ua haujlwm ntawm nickel slag sib tsoo.Peb pom zoo kom koj xaiv cov nickel ore ntsug sib tsoo zeb los hloov cov pob zeb tsoos ua cov cuab yeej tseem ceeb rau kev rov qab los thiab rov qab siv cov xuab zeb nickel ore slag.Covnpib tsib xee slag ultra-zoozebtxheej txheem ntawm npib tsib xee slagntsug sib tsoo zeb tau txais kev pom zoo, thiab qhov tsim nyog sib tsoo fineness yog ua tiav los ntawm kev hloov kho cov khoom lag luam kom ntseeg tau tias cov hmoov zoo ultra-nplua nrog thaj chaw tshwj xeeb ua tau raws li lub zog thiab kev ua haujlwm raws li kev siv hluav taws xob tsawg, kom tsis txhob muaj teeb meem ntawm cov hmoov zoo ntau dhau. los yog kev siv hluav taws xob siab tshwm sim los ntawm kev sib tsoo ntau dhau ntawm kev sib tsoo pob zeb.

HLM series npib tsib xee slagntsug sib tsoo zeb tsim los ntawm HCMilling (Guilin Hongcheng) tau siv dav hauv ntau hom khib nyiab rov ua dua tshiab thiab rov ua dua tshiab los tsim cov ntaub ntawv ntsuab cementitious, muab cov cuab yeej zoo txhawb rau kev rov qab los thiab rov qab siv cov xuab zeb nickel ore khib nyiab slag.Yog tias koj muaj qhov xav tau rau cov xuab zeb nickel ore khib nyiab rov ua dua thiab npib tsib xee slagsib tsoo zeb, thov hu rau HCM kom paub meej cov khoom siv.
