Nickel ni icyuma cy'ingenzi kidakoresha fer gifite ikoreshwa ritandukanye. Kiboneka cyane cyane mu mabuye ya nickel sulfide na nickel oxide. 30% by'umutungo wa nickel ni sulfide naho 70% ni laterite nickel ores. Kubera ko ubukene bwa nickel bukomeje kwiyongera ndetse n'ubuke bw'amabuye ya nickel sulfide bugenda bugabanuka buhoro buhoro, iterambere rya laterite nickel ore rigaragaza icyerekezo gikomeye. Mu gihe aside sulfuriki ya laterite nickel ore ibora, imyanda ya laterite nickel ore yabaye ikintu kibuza uburyo bwo gukuramo nickel itose. Nk'uruganda rukoranikeli ya slaguruganda rusya ruhagaze, HCMilling (Guilin Hongcheng) izabagezaho uburyo bwo kugarura no kongera gukoresha imyanda ya nickel ore ya lateritic.

Uburyo bwo kugarura no kongera gukoresha ibisigazwa by'imyanda ya nickel ya lateritike ni ugukaranga ibisigazwa by'imyanda ya nickel ya lateritike ku bushyuhe bwa 160 ~ 900 ℃ mu gihe cy'iminota 20 ~ 120, hanyuma nyuma yo gukonjesha bisanzwe, ubisya ubishyiremo ifu ukoresheje ibisigazwa bya 0.08 mm biri munsi ya 10% binyuze mu gusya. nikeli ya slaguruganda rusya ruhagazegutegura ibikoresho fatizo bya sima ya manyeziyumu, ibikoresho byo gusiga ku mihanda cyangwa putty y'irangi ku nkuta. Intambwe zihariye zo kugarura no kongera gukoresha slag ya nickel ya laterite nickel ni izi zikurikira:

(1) Agace k'ubushyuhe ka nikeli gafite ubushyuhe bwa 12% ~ 18% (uduce duto turi munsi ya mm 3 turenga 70%, kandi ubushyuhe bukaba bukomeye) karumishwa n'icyuma cyumisha vuba, ubushyuhe bukagabanuka bukagera munsi ya 3%, hanyuma kagashyirwa mu bubiko nyuma yo gukuraho icyuma mu byiciro byinshi, hanyuma ibikoresho bigashyirwa mu bubiko.nikeli ya slaguruganda rusya.

(2) Ifu yumye ya nickel ishyirwa mu ruganda rwa nickel slag kugira ngo ikoreshwe kandi isya nyuma yo kuyivanga (hongerwamo ingano ikwiye ya activator), hanyuma igatandukana n'umwuka utandukanye. Uduce duto dusubizwa munikeli ya slaguhagazeikizingourusyo, hanyuma ifu nziza isigaye yinjira mu cyuma gifata ifu hamwe n'umuyaga kugira ngo itegure umusaruro urangiye, hanyuma igashyirwa mu bubiko. Ifu ikomeye ifite ubuso bwihariye bwa <200m2/kg isubizwa mu ruganda rusya rwa nickel slag hanyuma igasenywa. Ifu imwe nziza cyane ifite ubuso bwihariye bwa >450m2/kg ikusanywa n'icyuma gikusanya ivumbi hanyuma kikajyanwa mu bubiko bw'ibicuruzwa byarangiye.

Ifu y'imyanda ya nickel ore slag mu by'ukuri ni uruvange rwa sulfate ya kalisiyumu, hydroxide ya manyeziyumu, hydrate ya silicate ya kalisiyumu na hydrate ya calcium aluminate ya kalisiyumu. Nyuma yo kumisha cyangwa gukaranga ubushyuhe buke, haboneka uruvange rwa sulfate ya kalisiyumu idafite amazi, oxide ya manyeziyumu, silicate ya dicalcium na calcium aluminate. Ifite imiterere isanzwe ya sima ya Portland, sima ya magnesite na gypsum. Ni ubwoko bushya bw'ibikoresho bikoreshwa muri sima kandi bikoreshwa cyane mu bwubatsi. Uburyo bwo kugarura no kongera gukoresha ifu y'imyanda ya nickel ore slag ya laterite ni bworoshye, ntibusaba ubushyuhe bwinshi, umuvuduko mwinshi n'ibikoresho bihenze, kandi biroroshye gushyira mu bikorwa. Uburyo bwonikeli ya slaguhagazeikizingourusyoni intambwe y'ingenzi cyane mu kugarura, kongera gukoresha no gukoresha umutungo wa laterite nickel slag, ingana na kimwe cya kabiri cy'ikoreshwa ry'ingufu zose, kugira ngo ugabanye ikiguzi cyo gukora, ikoreshwa ry'ingufu no kunoza imikorere myiza yo gusya nickel slag. Turakugira inama yo guhitamo uruganda rusya nickel ore vertical grinder kugira ngo rusimbuze uruganda rusanzwe rw'umupira nk'igikoresho cy'ingenzi cyo kugarura no kongera gukoresha laterite nickel ore slag.nikeli ya slag nziza cyaneurusyoinzira ya nikeli ya slaguruganda rusya ruhagaze byemejwe, kandi uburyo bwo gusya bukwiye bugerwaho hakoreshejwe uburyo bukwiye bwo guhindura imiterere y’ibikoresho kugira ngo harebwe ko hakorwa ifu nziza cyane ifite ubuso bwihariye bwujuje ingufu n’ibikorwa bikenewe mu gihe hakoreshwa ingufu nke, kugira ngo hirindwe ikibazo cy’ifu nziza nyinshi cyangwa ikoreshwa ry’ingufu nyinshi riterwa no gusya cyane mu buryo busanzwe.

urukurikirane rwa HLM rwa nikeli rwa slaguruganda rusya ruhagaze Byakozwe na HCMilling (Guilin Hongcheng) byakoreshejwe cyane mu buryo butandukanye bwo kongera gukoresha no kongera gukoresha imyanda mu gutunganya ibikoresho bisiga sima, bitanga ubufasha bwiza ku bikoresho byo kugarura no kongera gukoresha imyanda ya nickel ore ya laterite. Niba ukeneye kongera gukoresha imyanda ya nickel ore ya laterite na nikeli ya slaguruganda rusya, nyamuneka hamagara HCM kugira ngo umenye ibisobanuro birambuye ku bikoresho.
