Ọla kọpa sulfate, nke na-egosi dị ka kristal na-acha anụnụ anụnụ ma ọ bụ na-acha anụnụ anụnụ, bụ ihe na-arụ ọrụ nke ọma na sulfide ore flotation.A na-ejikarị ya dị ka onye na-arụ ọrụ, onye na-achịkwa na onye na-emechi ihe iji dozie uru pH nke slurry, na-achịkwa ọgbọ ụfụfụ ma melite ikike elu nke mineral nwere mmetụta na-arụ ọrụ na sphalerite, stibnite, pyrite na pyrrhotite, karịsịa sphalerite nke na-egbochi wayo. ma ọ bụ cyanide.
Ọrụ nke ọla kọpa sulfate na ịnweta flotation:
1. Ejiri ya dị ka activator
Nwere ike ịgbanwe ihe ọkụ eletrik nke elu ịnweta ma mee ka ịnweta elu hydrophilic.Nke a hydrophilicity nwere ike ime ka mpaghara kọntaktị dị n'etiti ịnweta na mmiri, na-eme ka ọ dịkwuo mfe ịnweta ịnweta mmiri.Ọla kọpa sulfate nwekwara ike na-etolite cations na ịnweta slurry, nke na-na-adsorbed n'elu nke ịnweta, na-amụba ya hydrophilicity na buoyancy.
Usoro ịgbalite gụnyere akụkụ abụọ ndị a:
①Mmeghachi omume metathesis na-eme n'elu ịnweta ịnweta ọrụ iji mepụta ihe nkiri mmalite.Dịka ọmụmaatụ, a na-eji sulfate ọla kọpa mee ka sphalerite rụọ ọrụ.Oghere nke ion ọla kọpa divalent yiri radius nke ion zinc, na solubility nke ọla kọpa sulfide dị obere karịa nke zinc sulfide.Ya mere, enwere ike ịmepụta ihe nkiri sulfide ọla kọpa n'elu sphalerite.Mgbe emechara ihe nkiri sulfide ọla kọpa, ọ nwere ike ịmekọrịta ngwa ngwa na onye na-anakọta xanthate, nke mere na sphalerite na-arụ ọrụ.
②Wepu ihe mgbochi mbụ, wee mepụta ihe nkiri ịgbalite.Mgbe sodium cyanide na-egbochi sphalerite, ion zinc cyanide kwụsiri ike na-etolite n'elu sphalerite, na ion cyanide ọla kọpa kwụsiri ike karịa ion zinc cyanide.Ọ bụrụ na a na-agbakwunye sulfate ọla kọpa na sphalerite slurry nke cyanide na-egbochi, cyanide radicals n'elu sphalerite ga-ada, na ion ọla kọpa na-akwụghị ụgwọ ga-emeghachi omume na sphalerite iji mepụta ihe nkiri na-arụ ọrụ nke ọla kọpa sulfide, si otú ahụ mee ka ọ rụọ ọrụ. sphalerite.
2. Ejiri ya dị ka onye na-achịkwa
Enwere ike imezi uru pH nke slurry.N'ihe bara uru pH kwesịrị ekwesị, sulfate ọla kọpa nwere ike meghachi omume na ion hydrogen n'elu ala ịnweta iji mepụta kemịkalụ kemịkalụ na-ejikọta na elu ịnweta, na-abawanye hydrophilicity na buoyancy nke ịnweta, si otú ahụ na-akwalite mmetụta flotation nke ọla edo.
3. Eji mee ihe dị ka ihe mgbochi
Enwere ike ịmepụta anions na slurry na adsorbed n'elu nke mineral ndị ọzọ na-adịghị achọ flotation, na-ebelata ha hydrophilicity na buoyancy, si otú na-egbochi ndị a mineral si n'elu ọnụ na gold minerals.A na-agbakwunyekarị ndị na-egbochi ọla kọpa sulfate na slurry iji dobe mineral ndị na-achọghị flotation na ala.
4. A na-eji dị ka ịnweta elu modifier
Gbanwee kemịkalụ na ihe anụ ahụ nke elu ịnweta.Na ọla edo flotation, ihe ọkụ eletrik na hydrophilicity nke ịnweta elu bụ isi ihe na-ese n'elu mmiri.Ọla kọpa sulfate nwere ike ịmepụta ion ọla kọpa oxide na slurry ịnweta, meghachi omume na ion metal n'elu ịnweta, ma gbanwee ihe ndị dị n'elu ya.Ọla kọpa sulfate nwekwara ike ịgbanwe hydrophilicity nke ịnweta na-ebupụta ma mee ka mpaghara kọntaktị dị n'etiti mineral na mmiri, si otú ahụ na-akwalite mmetụta flotation nke mines ọla edo.
