Ndị na-anakọtakarị maka ndị na-ebu ụzọ na-agụnye ya
1. Xanthate. Ofdị a na-ahụ maka onye na-elekọta ya gụnyere Xanthate, Xanthate Ester, wdg.
2. Sulfur nitrogen, dika Ethl sulfur nitrogen, nwere ikike nchịkọta siri ike karịa Xanthate. O nwere ikike nnakọta dị ike maka Galcopyrite, mana ike adịghị ike ijikọta pyrite, ezigbo nhọrọ maka ọsọ ọsọ, na ole na ole na-eji Xanthate. O nwere ruru nchịkọta siri ike maka ihe dị oke mkpa maka sọlfọ. Mgbe ejiri ya mee ihe maka ịhazi mkpụrụ osisi ọla kọpa na sọlfọ, ọ nwere ike nweta nsonaazụ ka mma karịa Xanthate.
3.black ọgwụ
Black ntụ bụ ihe na-anakọta nke sọlfọ ma ọ bụ na ike nchịkọta ya adịghị ike karịa nke Xanthate. Ngwaọrụ na-edozi ahụ nke Dihyddrocarbyl Dithiophosphate nke otu igwe ion buru ibu karịa nke Xanthate nke kwekọrọ ion. Ọgwụ ojii nwere ihe na-atọ ụtọ.
A na-ejikarị ike iji ike dị egwu na ụlọ ọrụ gụnyere: Mba. 25 ntụ ntụ, na-acha oji ojii, abụ na ntụ ntụ ojii. N'etiti ha, ma na-acha uhie uhie (Dibutymm dithophfate) bụ ntụ ntụ na mmiri, na-agbanye oji mgbe ị nwesịrị ihe ndị na-atọ ụtọ. Ọ dị mma maka ịkwadebe nke sọlfọ orper dị ka ọla kọpa, na-eduga, zin, na nickel. . N'adịghị ike alkaline slurry, ike nchịkọta nke Pyrite na Pyrrrotite adịghị ike, mana ikike nnakọta nke Galena siri ike.

Dabere na ọrụ ha na usoro ọgwụgwọ, enwere ike ekewa ya: ndị na-eme ihe nkiri, ndị ọrụ na-ere ahịa, ndị na-ere ahịa na-agbasa, slime slime na Reaglants.
Ndị na-edozi ahụ gụnyere ogige inorganic dị iche iche (dị ka nnu, ntọala na acids) na ogige. Otu ụlọnga ahụ na-arụkarị ọrụ dị iche iche n'okpuru ọnọdụ ezumike dị iche iche.
Inhibitors:
1. O siri ike inufe na mmiri ma ọ bụ alkali siri ike. Mmeghachi omume mgbe agbakwunye na mpempe akwụkwọ slurry dị ka ndị a:
Cao + h2o = ca (oh) 2
Ca (oh) 2 = caoh ++
Cah + = ca2 ++-
A na-ejikarị wayo na-abawanye uru nke slurry ma gbochie minineral sọlfọ. N'ime ọla kọpa, na-eduga, na zinc, na -akarị, ha na-ejikarị ya na sọlfọ, pykasate, na pyroatenite (dị ka arsenopyrite)). Iji ọla kọpa nke ka mma, na-eduga na mineral zinc, lime na-agbakwunye na-egbochi mineral sọlfọ.
2. Cyanide (Nacn, Kcn)
Cyanide bụ ihe dị irè na-arụ ọrụ n'oge ndu na ịhazi. A na-ejikwa cyanide bụ sodium carium na potassium cyanide, ejikwa cyanide.
Nnu na-eme nnu site na ala siri ike na acid na-esighi ike. Ọ bụ hydrolyzed na slurry iji mepụta Hcn na CN-
KCN = K ++ cn-
Cn + h2o = hcn ++
Enwere ike ịhụ ya site na nha nha dị elu nke dị na alkaline slurry, ịta nke cn- abawanye, nke bara uru na nsogbu. Ọ bụrụ na nke ahụ belata, HCDN (acidcyanic acid) a na-akpụzi na nsonaazụ inhibitory na-ebelata. Ya mere, mgbe ị na-eji Cyanide, a ga-enwe ụdị alkaline nke slurry.
3.Zinn sulfate
Ngwaahịa dị ọcha nke zinc sulfate dị ọcha kristal, ọ na-agbanye ya na mmiri, ma na-egbochi sphalerite. Ọ na - enwekarị inhibitory mmetụta naanị na alkaline slurry. Nke dị elu ph nke slurry, mmetụta ya pụtara ìhè karị. Zinc sulfate na-emepụta mmeghachi omume ndị a na mmiri:
ZNSO4 = ZNN2 ++ DA42-
ZN2 ++ 2h20 = zn (oh) 2 + 2h +
ZN (Oh) 2 bụ ampphite gụnyere nke na-agbanye na acid iji mepụta nnu.
ZN (Oh) 2 + H2S04 = ZNNO4 + 2H2O
Na alkaline ọkara, hzno2- na zno22- nweta. Mgbakwunye ha na mineral na-eme ka mmiri na-eme nri.
ZN (oh) 2 + na na na na na na na na na na na na na na na na
ZN (Oh) 2 + 2nah = Na2ZNO2 + 2H2O
Mgbe ejiri ya na zinc sulfate naanị, nsonaazụ ndị na-enweghị nsogbu. A na-ejikarị ya na cyanide, sodium sulfide, sọlfọ ma ọ bụ thiososfate, sodium carbonate, wdg.
Ejiji jikọtara ya na zinc sulfate na cyanide nwere ike ịkwalite mmetụta ndị na-egbochi ya na Sphalerite. Ihe a na-ejikarị ya bụ: Cyanide: zinwụrụ: zinc sulfate = 1: 2-5. N'oge a, CN- na ZN2 + form colloidal zn (cn) 2 prepipipiter.
