Nickel ndichitsulo chofunikira chosakhala ndi chitsulo chomwe chimagwiritsidwa ntchito mosiyanasiyana.Amapezeka makamaka mu nickel sulfide ndi nickel oxide ores m'chilengedwe.30% ya zinthu za nickel ndi miyala ya sulfide ndipo 70% ndi miyala ya nickel ya laterite.Pakuchulukirachulukira kwa nickel ndi kuchepa kwapang'onopang'ono kwa nickel sulfide ore, kukula kwa nickel ore ya laterite kukuwonetsa mayendedwe amphamvu.Mu njira ya sulfuric acid kuwonongeka kwa laterite nickel ore, zotsalira za nickel za lateite zakhala chinthu cholepheretsa kunyowa kwa nickel.Monga wopanganickel slagofukula mphero, HCMilling(Guilin Hongcheng) akufotokozerani njira zobwezeretsanso ndikugwiritsanso ntchito nickel ore zinyalala slag kwa inu pansipa.

Njira yobwezeretsanso ndikugwiritsanso ntchito zotsalira za nickel ore ndi calcine lateritic nickel ore zotsalira pa 160 ~ 900 ℃ kwa 20 ~ 120 min, ndipo mutatha kuzirala kwachilengedwe, perani kukhala zinthu za ufa ndi zotsalira za 0.08 mm sieve zosakwana 10% kudzera nickel slagofukula mpheroKukonzekera zopangira za simenti ya magnesium, zinthu zochiritsira zamsewu kapena zomangira zopangira khoma.Njira zenizeni zobwezeretsera ndikugwiritsanso ntchito lateite nickel ore slag ndi izi:

(1) Nickel slag yokhala ndi chinyezi cha 12% ~ 18% (tinthu tating'onoting'ono m'munsi mwa 3 mm nkhani yopitilira 70%, kukhuthala kwake ndi kolimba) kumawumitsidwa ndi chowumitsira mwachangu, chinyezi chimachepetsedwa kukhala chocheperako. 3%, ndiyeno amayikidwa mu yosungirako pambuyo multistage chitsulo kuchotsa mankhwala, ndi zosakaniza anaika munickel slagmphero.

(2) Slag yowuma ya nickel imadyetsedwa mu mphero ya nickel slag kuti itulutse ndi kuphwanya pambuyo pa batching (kuwonjezera kuchuluka koyenera kwa activator), ndiyeno imasiyanitsidwa ndi kupatukana kwa mpweya.The coarse particles amabwerera kunickel slagofukulawodzigudubuzamphero, ndipo ufa wotsala wotsalayo umalowa mu concentrator ufa ndi mphepo kuti ukonze zomalizidwa, zomwe zimayikidwa mu yosungirako.Ufa wokhuthala wokhala ndi malo enaake a<200m2/kg umabwereranso ku mphero ya faifi tambala yowongoka ndikuphwanyidwa.Ufa wina wapamwamba kwambiri wokhala ndi malo opitilira 450m2/kg amatengedwa ndi otolera fumbi kenako amawatengera kumalo osungira katundu.

Laterite nickel ore waste slag kwenikweni ndi osakaniza a calcium sulfate, magnesium hydroxide, calcium silicate hydrate ndi calcium aluminate hydrate.Pambuyo poyanika kapena kutentha pang'ono, kusakaniza kwa anhydrous calcium sulfate, magnesium oxide, dicalcium silicate ndi calcium aluminate kumachitika.Ili ndi mawonekedwe wamba a simenti ya Portland, simenti ya maginito ndi gypsum.Ndi mtundu watsopano wazinthu zopangira simenti ndipo zimagwiritsidwa ntchito kwambiri pantchito yomanga.Kubwezeretsa ndikugwiritsanso ntchito njira ya laterite nickel ore waste slag ndi yosavuta, sikumaphatikizapo kutentha kwakukulu, kuthamanga kwambiri ndi zipangizo zamtengo wapatali, ndipo n'zosavuta kugwiritsa ntchito.Ndondomeko yanickel slagofukulawodzigudubuzampherondiye gawo lofunikira kwambiri pakubwezeretsa, kugwiritsiranso ntchito komanso kugwiritsa ntchito zida za laterite nickel slag, kuwerengera pafupifupi theka la mphamvu zonse zomwe zimagwiritsidwa ntchito, kuti achepetse ndalama zopangira, kugwiritsa ntchito mphamvu komanso kupititsa patsogolo mphamvu ya nickel slag.Tikukulimbikitsani kuti musankhe mphero ya nickel ore of vertical mphero kuti mulowe m'malo mwa mphero yachikhalidwe ngati chida chachikulu chobwezeretsanso ndikugwiritsanso ntchito laterite nickel ore slag.Thenickel slag zabwino kwambirimpherondondomeko ya nickel slagofukula mphero amavomerezedwa, ndipo kupukuta koyenera kumatheka mwa kusintha bwino gululi kuti liwonetsetse kupanga ufa wochuluka kwambiri wokhala ndi malo enieni okhudzana ndi mphamvu ndi ntchito zomwe zimagwiritsidwa ntchito pogwiritsira ntchito mphamvu zochepa, kuti apewe vuto la ufa wochuluka kwambiri. kapena kugwiritsa ntchito mphamvu kwambiri chifukwa cha kugawika kwakukulu kwa mphero zachikhalidwe za mpira.

HLM mndandanda wa nickel slagofukula mphero opangidwa ndi HCMilling(Guilin Hongcheng) wakhala chimagwiritsidwa ntchito mitundu yosiyanasiyana ya zinyalala slag yobwezeretsanso ndi zobwezeretsanso kutulutsa zobiriwira cementitious zipangizo, kupereka zabwino zida thandizo kuchira ndi kugwiritsiranso ntchito laterite faifi tambala ore zinyalala slag.Ngati muli ndi kufunika kwa laterite nickel ore zinyalala zobwezeretsanso ndi nickel slagmphero, chonde lemberani HCM kuti mudziwe zambiri za zida.
