Nikkel waa bir muhiim ah oo aan bir ahayn oo leh isticmaal badan. Waxay inta badan ka dhacdaa macdanta nikkel sulfide iyo nikkel oxide dabiiciga ah. 30% kheyraadka nikkel waa macdanta sulfide halka 70% ay yihiin macdanta nikkel laterite. Iyadoo baahida sii kordheysa ee nikkel iyo hoos u dhaca tartiib tartiib ah ee macdanta nikkel sulfide, horumarinta macdanta nikkel laterite waxay muujinaysaa isbeddel xooggan. Habka kala-goynta aashitada sulfuric ee macdanta nikkel laterite, haraaga qashinka ee macdanta nikkel laterite waxay noqotay arrin xaddidaysa habka soo saarista nikkel qoyan. Soo-saare ahaanslag nikkel ahwarshad shiidi toosan, HCMilling (Guilin Hongcheng) ayaa hoos kuugu soo bandhigi doonta hababka soo kabashada iyo dib u isticmaalka qashinka nikkel-ka ee lateric.

Habka loo soo celiyo loona isticmaalo dib u isticmaalka haraaga qashinka nickel-ka ee lateritic waa in la kariyo haraaga qashinka nickel-ka ee lateritic-ga heerkul ah 160 ~ 900 ℃ muddo 20 ~ 120 daqiiqo ah, ka dib qaboojinta dabiiciga ah, ku shiidi budo iyadoo la isticmaalayo haraaga shaandhada 0.08 mm oo ka yar 10% ilaa slag nikkel ahwarshad shiidi toosansi loo diyaariyo walxo cayriin ah oo ka samaysan sibidhka magnesium, walxaha lagu daadiyo saldhigga wadada ama rinjiga derbiga dhismaha. Tallaabooyinka gaarka ah ee soo kabashada iyo dib u isticmaalka slag-ka nickel-ka ee laterite waa sidan soo socota:

(1) Jajabka nikkelka oo leh qoyaan dhan 12% ~ 18% (walxaha yaryar ee ka hooseeya 3 mm waxay ka badan yihiin 70%, dhesquskuna waa xoog badan yahay) waxaa lagu qalajiyaa qalajiye si degdeg ah u karkaraya, qoyaanka waxaa loo dhimaa wax ka yar 3%, ka dibna waxaa la geliyaa kaydinta ka dib daaweynta ka saarista birta marxalado badan leh, maaddooyinkana waxaa lagu shubaaslag nikkel ahwarshad shiidi.

(2) Nikkel-ka la qalajiyey waxaa lagu shubaa warshadda nikkel-ka si loo soo saaro oo loo burburiyo ka dib marka la isku daro (iyadoo lagu darayo xaddi ku habboon oo firfircooni ah), ka dibna waxaa kala soocaya hawo. Qaybaha qallafsan waxaa lagu celiyaaslag nikkel ahToosanroogagawarshad, budada khafiifka ah ee soo hartayna waxay gashaa kaydka budada iyadoo la adeegsanayo dabaysha si loo diyaariyo badeecada la dhammeeyay, ka dibna la geliyo kaydinta. Budada qallafsan ee leh meel gaar ah oo dusha sare ah oo <200m2/kg ah ayaa lagu celiyaa warshadda shiididda toosan ee nikkel slag ka dibna la burburiyaa. Budada aadka u khafiifka ah oo leh meel gaar ah oo dusha sare ah oo ah>450m2/kg ayaa ururisa boorka ka dibna si toos ah ayaa loogu qaadaa bakhaarka alaabta la dhammeeyay.

Qashinka macdanta nikkel ee Laterite waa isku darka kalsiyum sulfate, magnesium hydroxide, calcium silicate hydrate iyo calcium aluminate hydrate. Ka dib marka la qalajiyo ama heerkul hooseeya lagu kariyo, isku darka calcium sulfate aan biyo lahayn, magnesium oxide, dicalcium silicate iyo calcium aluminate ayaa la helaa. Waxay leedahay astaamaha caadiga ah ee sibidhka Portland, sibidhka magnesite iyo gypsum. Waa nooc cusub oo walxo sibidh ah waxayna si ballaaran u isticmaashaa warshadaha dhismaha. Habka soo kabashada iyo dib u isticmaalka qashinka nikkel ee laterite waa mid fudud, kuma lug laha heerkul sare, cadaadis sare iyo walxo qaali ah, waana mid fudud in la hirgeliyo. Habkaslag nikkel ahToosanroogagawarshadwaa tallaabada ugu muhiimsan ee soo kabashada, dib u isticmaalka iyo isticmaalka kheyraadka ee slag nickel laterite, taasoo ka dhigan qiyaastii kala bar isticmaalka korontada guud, si loo yareeyo kharashyada wax soo saarka, isticmaalka tamarta iyo in la horumariyo hufnaanta shiididda slag nickel. Waxaan kugula talineynaa inaad doorato warshadda shiididda toosan ee nickel ore si aad u beddesho warshadda kubbadda dhaqameed oo ah qalabka ugu muhiimsan ee soo kabashada iyo dib u isticmaalka slag nickel ore laterite.slag nikkel ah aad u fiicanwarshadhabka slag nikkel ahwarshad shiidi toosan waa la qaataa, waxaana la helaa tayada shiididda ee ku habboon iyadoo si macquul ah loo hagaajinayo kala-soocidda si loo hubiyo soo saarista budada aadka u fiican oo leh meel gaar ah oo daboolaysa shuruudaha xoogga iyo dhaqdhaqaaqa marka la isticmaalayo awood yar, si looga fogaado dhibaatada ka dhalata budada xad-dhaafka ah ama isticmaalka tamarta sare ee ay keento dhacdada shiididda xad-dhaafka ah ee shiididda kubbadda dhaqameed.

Slag nickel taxane ah oo HLM ahwarshad shiidi toosan Shirkadda HCMill (Guilin Hongcheng) ayaa si weyn loogu isticmaalay noocyo kala duwan oo dib-u-warshadaynta qashinka iyo dib-u-warshadaynta si loo soo saaro agabyada sibidhka cagaaran, iyadoo bixinaysa taageero qalab oo wanaagsan oo loogu talagalay soo kabashada iyo dib-u-warshadaynta qashinka nickel-ka ee laterite. Haddii aad haysato baahida dib-u-warshadaynta qashinka nickel-ka ee laterite iyo slag nikkel ahwarshad shiidi, fadlan la xiriir HCM si aad u hesho faahfaahinta qalabka.
