I-Nickel iyinsimbi ebalulekile engeyona insimbi enokusetshenziswa okubanzi. Itholakala kakhulu kuma-ore e-nickel sulfide kanye nama-ore e-nickel oxide ngokwemvelo. Ama-30% emithombo ye-nickel angama-ore e-sulfide kanti ama-70% angama-ore e-nickel e-laterite. Njengoba isidingo se-nickel sikhula kanye nokuncipha kancane kancane kwe-ore ye-nickel sulfide, ukuthuthukiswa kwe-ore ye-nickel ye-laterite kubonisa ukuthambekela okukhulu. Enkambisweni yokubola kwe-sulfuric acid ye-ore ye-nickel ye-laterite, insalela yemfucuza ye-ore ye-nickel ye-laterite isibe yinto evimbela inqubo yokukhipha i-nickel emanzi. Njengomkhiqizi wei-nickel slagumshini wokugaya oqondile, I-HCMilling (Guilin Hongcheng) izokwethula izindlela zokubuyisa nokuphinda kusetshenziswe imfucuza ye-nickel ore ye-lateritic ngezansi.

Indlela yokubuyisa nokuphinda kusetshenziswe insalela yemfucuza ye-nickel ore ye-lateritic iwukuba i-calcine insalela yemfucuza ye-nickel ore ye-lateritic ku-160~900 ℃ imizuzu engama-20~120, bese kuthi ngemva kokupholisa ngokwemvelo, igaye ibe yizinto eziwuphuphu ngensalela yesihlungo engu-0.08 mm ngaphansi kuka-10% ngokusebenzisa. i-nickel slagumshini wokugaya oqondileukulungisa izinto zokusetshenziswa zesamente ye-magnesium, izinto zokulungisa isisekelo somgwaqo noma i-putty yopende wodonga lwesakhiwo. Izinyathelo ezithile zokubuyisa nokusetshenziswa kabusha kwe-laterite nickel ore slag yilezi ezilandelayo:

(1) I-nickel slag enomswakama ongu-12% ~ 18% (izinhlayiya ezincane ezingaphansi kuka-3 mm zingaphezu kuka-70%, futhi i-viscosity inamandla) yomiswa nge-dryer ebilisayo ngokushesha, okuqukethwe komswakama kuncishiswa kube ngaphansi kuka-3%, bese kufakwa endaweni yokugcina ngemuva kokwelashwa kokususwa kwensimbi ngezigaba eziningi, bese izithako zifakwa ku-i-nickel slagumshini wokugaya.

(2) I-nickel slag eyomile ifakwa emshinini wokugaya i-nickel slag ukuze ikhishwe futhi ichotshozwe ngemva kokuhlanganiswa (kufakwe inani elifanele le-activator), bese ihlukaniswa ngokuhlukaniswa komoya. Izinhlayiya eziqinile zibuyiselwa ku-i-nickel slagokuqondilei-rollerumshini wokugaya, bese kuthi i-powder ecolekile esele ingena ku-powder concentrator nomoya ukuze ilungiselele umkhiqizo oqediwe, bese ufakwa endaweni yokugcina. I-powder ecolekile enendawo ethile yobuso engu-<200m2/kg ibuyiselwa ku-nickel slag vertical grinding mill bese ichotshozwa. Enye i-powder ecolekile kakhulu enendawo ethile yobuso engu->450m2/kg iqoqwa ngumqoqi wothuli bese ithuthwa ngqo endaweni yokugcina impahla yomkhiqizo oqediwe.

I-Laterite nickel ore waste slag empeleni iyingxube ye-calcium sulfate, i-magnesium hydroxide, i-calcium silicate hydrate kanye ne-calcium aluminate hydrate. Ngemva kokomiswa noma ukubalwa kwezinga lokushisa eliphansi, kutholakala ingxube ye-anhydrous calcium sulfate, i-magnesium oxide, i-dicalcium silicate kanye ne-calcium aluminate. Inezici ezivamile ze-Portland cement, i-magnesium cement kanye ne-gypsum. Luhlobo olusha lwezinto ezisetshenziswa nge-cementitious futhi lusetshenziswa kabanzi embonini yokwakha. Inqubo yokubuyisa nokusebenzisa kabusha i-laterite nickel ore waste slag ilula, ayibandakanyi izinga lokushisa eliphezulu, umfutho ophezulu kanye nezinto ezibizayo, futhi kulula ukuyisebenzisa. Inqubo yei-nickel slagokuqondilei-rollerumshini wokugayaisinyathelo esibaluleke kakhulu ekubuyiselweni, ukusetshenziswa kabusha kanye nokusetshenziswa kwemithombo ye-laterite nickel slag, ebalwa cishe ingxenye yokusetshenziswa kwamandla okuphelele, ukuze kuncishiswe izindleko zokukhiqiza, ukusetshenziswa kwamandla kanye nokuthuthukisa ukusebenza kahle kokugaya i-nickel slag. Sincoma ukuthi ukhethe umshini wokugaya oqondile we-nickel ore ukuze uthathe indawo yomshini wokugaya ibhola wendabuko njengemishini eyinhloko yokubuyisa nokusetshenziswa kabusha kwe-laterite nickel ore slag.i-nickel slag okuhle kakhuluumshini wokugayainqubo ye i-nickel slagumshini wokugaya oqondile kuyamukelwa, futhi ubuncane bokugaya obufanele butholakala ngokulungisa ngokufanele i-classifier ukuqinisekisa ukukhiqizwa kwempuphu ecolekile kakhulu ene-surface area ethile ehlangabezana nezidingo zamandla nomsebenzi ngaphansi kokusetshenziswa kwamandla aphansi, ukuze kugwenywe inkinga yokuqukethwe kwempuphu ecolekile ngokweqile noma ukusetshenziswa kwamandla aphezulu okubangelwa yisimo sokugaya ngokweqile kwebhola lendabuko.

I-HLM series nickel slagumshini wokugaya oqondile I-HCMilling (Guilin Hongcheng) isetshenziswe kabanzi ezinhlotsheni ezahlukene zokuvuselela nokuvuselela imfucuza ukuze kukhiqizwe izinto eziluhlaza okotshani, okuhlinzeka ngokusekelwa okuhle kwemishini yokubuyisa nokusetshenziswa kabusha kwemfucuza ye-nickel ore ye-laterite. Uma unesidingo sokuvuselela imfucuza ye-nickel ore ye-laterite kanye i-nickel slagumshini wokugaya, sicela uxhumane ne-HCM ukuthola imininingwane yemishini.
