Ihe na-eme ka mmiri na-efegharị n'ime ụzọ-zinc ore flotation usoro

Ngwa nke lead-zinc ore ga-erite uru tupu enwee ike iji ya nke ọma.Usoro uru a na-ejikarị bụ flotation.Ebe ọ bụ ihe na-ese n'elu mmiri, kemịkalụ flotation enweghị ike kewaa.Ihe na-esonụ bụ mmalite nke reagents na-ese n'elu mmiri na-eji na lead-zinc ore:
1. Lead na zinc flotation regulators: Enwere ike kewaa ndị na-achịkwa n'ime ndị na-emechi ihe, ndị na-eme ihe, ndị na-ahụ maka pH na-ajụ, slime dispersants, coagulants na re-coagulants dị ka ọrụ ha na-arụ na flotation usoro.Ndị na-achịkwa gụnyere ogige inorganic dị iche iche (dịka nnu, bases na acids) na ogige organic.Otu onye nnọchi anya na-arụkarị ọrụ dị iche iche n'okpuru ọnọdụ flotation dị iche iche.
2. Ndị na-anakọta flotation ndu na zinc.Ndị nchịkọta a na-ejikarị gụnyere: xanthate na ọgwụ ojii.Klas Xanthate gụnyere xanthate, xanthate esters, wdg Sulfur nitrogen klas, dị ka ethyl sulfide, nwere ikike nchịkọta siri ike karịa xanthate.Ọ nwere ikike nchịkọta siri ike nke galena na chalcopyrite, na ikike nnakọta pyrite ya na-edozi.Adịghị ike, nhọrọ dị mma, ọsọ flotation ọsọ ọsọ, abaghị uru karịa xanthate, ma nwee oke njide siri ike maka ụmụ irighiri ihe sulfide.Mgbe ejiri ya na nkewa nke ọla kọpa-lead-sulfur ratio ore, ọ nwere ike nweta mma karịa xanthate.Mmetụta nhazi ka mma.Ọgwụ ojii ọgwụ ojii bụ onye na-anakọta ores sulfide dị irè.Ike nnakọta ya adịghị ike karịa nke xanthate.Ngwaahịa solubility nke dihydrocarbyl dithiophosphate nke otu ion metal dị ukwuu karịa nke xanthate nke ion kwekọrọ.Ọgwụ ojii O nwere ihe na-afụ ụfụ.Uzuzu ojii a na-ejikarị eme ihe na ụlọ ọrụ gụnyere: Mba 25 ntụ ntụ ojii, ntụ ntụ ojii butylammonium, amine ojii ntụ ntụ, na ntụ ntụ ojii naphthenic.N'ime ha, butylammonium black powder (dibutyl ammonium dithiophosphate) bụ ntụ ntụ na-acha ọcha nke dị mfe Ọ na-agbaze na mmiri, na-atụgharị oji mgbe ọ nwụsịrị, ma nwee ụfọdụ ụfụfụ.Ọ dabara maka flotation nke sulfide ore dị ka ọla kọpa, lead, zinc, na nickel.
Na mgbakwunye, cyanide nwere ike igbochi sphalerite siri ike, na zinc sulfate, thiosulfate, wdg nwere ike igbochi flotation nke sphalerite.
