I-Nickel iyinsimbi ebalulekile engafaki insimbi enobubanzi bokusetshenziswa.Ivela kakhulu ku-nickel sulfide kanye ne-nickel oxide ores emvelweni.U-30% wezinsiza ze-nickel yi-sulfide ores kanti u-70% ungama-lateite nickel ores.Ngokukhula kwesidingo se-nickel kanye nokuncipha kancane kancane kwe-nickel sulfide ore, ukuthuthukiswa kwe-lateite nickel ore kukhombisa ukuthambekela okunamandla.Enqubweni yokubola kwe-sulfuric acid ye-lateite nickel ore, insalela yemfucuza ye-lateite nickel ore isibe isici esivimbela inqubo yokukhipha i-nickel emanzi.Njengomkhiqizi wei-nickel slagumshini wokugaya ume mpo, I-HCMilling(Guilin Hongcheng) izokwethula izindlela zokuthola kabusha nokusetshenziswa kabusha kwe-latetitic nickel ore waste slag kuwe ngezansi.

Indlela yokutholwa kanye nokusetshenziswa kabusha kwezinsalela zemfucumfucu ye-nickel ore iwukuba i-calcine latetitic nickel ore izinsalela ku-160~900 ℃ imizuzu engu-20~120, futhi ngemva kokupholisa ngokwemvelo, igaye ibe yimpushana enensalela yesisefo engu-0.08 mm ngaphansi kuka-10% ngokusebenzisa i-nickel slagumshini wokugaya ume mpoukulungisa impahla eluhlaza kasimende we-magnesium, impahla yokwelapha isisekelo somgwaqo noma i-putty yopende wokwakha.Izinyathelo eziqondile zokutholwa kanye nokusetshenziswa kabusha kwe-lateite nickel ore slag zimi kanje:

(1) I-nickel slag enomswakama ongu-12% ~ 18% (izinhlayiya ezinhle ezingaphansi kuka-3 mm zenza ngaphezu kuka-70%, futhi i-viscosity inamandla) yomiswa ngesomiso esibilayo esisheshayo, okuqukethwe komswakama kuyehla kube ngaphansi I-3%, bese ifakwa endaweni yokugcina ngemuva kokwelashwa kokukhipha insimbi eningi, bese kufakwa izithakoi-nickel slagumshini wokugaya.

(2) I-nickel slag eyomile ifakwa esigayweni se-nickel slag ukuze ikhishwe futhi igaywe ngemva kokuxutshwa (ukwengeza inani elifanele le-activator), bese ihlukaniswa ngokuhlukaniswa komoya.Izinhlayiya ezimahhadla zibuyiselwa ku-i-nickel slagmporollerisigayo, futhi i-powder esele esele ingena ku-powder concentrator ngomoya ukuze kulungiswe umkhiqizo oqediwe, obese ufakwa endaweni yokugcina.Impushana eqinile enendawo ethize engu-<200m2/kg ibuyiselwa kumshini wokugaya we-nickel slag oqondile bese ugaywa.Enye impushana ecwebe kakhulu enendawo ethize engaphezu kuka-450m2/kg iqoqwa umqoqi wothuli bese iyiswa ngqo endaweni yokugcina impahla eqediwe.

I-Laterite nickel ore waste slag empeleni iyingxube ye-calcium sulfate, i-magnesium hydroxide, i-calcium silicate hydrate ne-calcium aluminate hydrate.Ngemuva kokumisa noma ukushisa okuphansi kwe-calcination, ingxube ye-anhydrous calcium sulfate, i-magnesium oxide, i-dicalcium silicate ne-calcium aluminate iyatholakala.Inezici ezivamile zikasimende wasePortland, usimende we-magnesite kanye negypsum.Iwuhlobo olusha lwe-cementitious material futhi lusetshenziswa kabanzi embonini yezokwakha.Inqubo yokubuyisela nokusetshenziswa kabusha kwe-lateite nickel ore waste slag ilula, ayibandakanyi izinga lokushisa eliphezulu, ukucindezela okuphezulu nezinto ezibizayo, futhi kulula ukuyisebenzisa.Inqubo yei-nickel slagmporollerisigayokuyisinyathelo esibaluleke kakhulu ekubuyiseleni, ekusetshenzisweni kabusha nasekusetshenzisweni kwensiza i-lateite nickel slag, ebalwa cishe ingxenye yengqikithi yokusetshenziswa kwamandla, ukuze kwehliswe izindleko zokukhiqiza, ukusetshenziswa kwamandla kanye nokuthuthukisa ukusebenza kahle kokugaya i-nickel slag.Sincoma ukuthi ukhethe isigayo se-nickel ore esime mpo ukuze umiselele isigayo sebhola esivamile njengesisetshenziswa esiyinhloko sokuthola nokusetshenziswa kabusha kwe-lateite nickel ore slag.Ii-nickel slag ultra-fineisigayoinqubo ye i-nickel slagumshini wokugaya ume mpo kwamukelwa, futhi ukucoleka okufanele kokugaya kufinyelelwa ngokulungisa isihlukanisi ngokunengqondo ukuze kuqinisekiswe ukukhiqizwa kwempushana ecwebezelayo enendawo ethile ehlangabezana nezidingo zamandla nomsebenzi ngaphansi kokusetshenziswa kwamandla aphansi, ukuze kugwenywe inkinga yokuqukethwe kwempushana ecolekile ngokweqile. noma ukusetshenziswa kwamandla okuphezulu okubangelwa into yokugaya ngokweqile yokugaya ibhola lendabuko.

HLM uchungechunge nickel slagumshini wokugaya ume mpo ekhiqizwe i-HCMilling(Guilin Hongcheng) isetshenziswe kabanzi ezinhlotsheni ezahlukene zokugaywa kabusha kwe-slag kanye nokugaywa kabusha ukuze kukhiqizwe izinto zikasimende eziluhlaza, okuhlinzeka ngosizo oluhle lwemishini yokubuyiswa nokusetshenziswa kabusha kwe-lateite nickel ore waste slag.Uma unesidingo sokugaywa kabusha kwemfucuza ye-nickel ore kanye i-nickel slagumshini wokugaya, sicela uthinte i-HCM ngemininingwane yesisetshenziswa.
