Ukusebenzisana kweSodium Sulfide kunye nezinye iiReagents kwiNkqubo yeFlotation

Kwintsimi ye Ukulungiswa kwezimbiwa, i-flotation yindlela esetyenziswa ngokubanzi yokwahlula izimbiwa ezixabisekileyo kwi-gange. I-sodium sulfide idlala indima ebalulekileyo kule nkqubo, ikakhulu isetyenziselwa ukunyenyisa ixabiso le-pH ye-pulp, i-sulfidize, i-depress, kunye nokuhlubula umphezulu weeminerali. Ukunxibelelana nayo Abaqokeleli, Abazalwana, yaye Abalawuli zintsonkothile kwaye zinefuthe elibonakalayo ekusebenzeni kunye nokukhetha kokudada.

Ukusebenzisana nabaqokeleli

Impembelelo kubaqokeleli beMineral yeSulfidi

Kuba abaqokeleli ngokuqhelekileyo ezisetyenziswa sulfide izimbiwa ezifana xanthates kunye dithiophosphates, xa ithamo I-sodium sulfide ifanelekile, inokuphucula i-hydrophobicity ye-sulfide mineral surface, ivumela abaqokeleli ukuba babhengeze ngcono kumphezulu wezimbiwa kunye nokuphucula ukujikeleza kweeminerali. Nangona kunjalo, xa i-sodium sulfide igqithise, iya kwenza ifilimu ye-hydrophilic kumphezulu wamaminerali e-sulfide, ukuthintela i-adsorption yabaqokeleli kwaye ngaloo ndlela idlala indima yokuvimbela. Ngokomzekelo, kwi-flotation ye-copper-sulfur ore, isixa esifanelekileyo se-sodium sulfide inokukhuthaza ukuqokelela kwe-chalcopyrite nge-xanthate, ngelixa inani eligqithisileyo liya kuthintela ukujikeleza kwe-chalcopyrite.

Impembelelo kwi-Oxide Mineral Collectors

Kwi-flotation yeeminerali ze-oxide, i-sodium sulfide inokwenza i-sulfidize ebusweni beeminerali ze-oxide, ezivumela ukuba ziqokelelwe ngabaqokeleli bamaminerali e-sulfide. Umzekelo, xa usebenzisa abaqokeleli acid okunamafutha ukudada cerussite, sulfide sodium kuqala sulfidizes umphezulu cerussite kwaye ke isebenzisana umqokeleli okunamafutha acid, ukuphucula isiphumo flotation of cerussite.

Unxibelelwano kunye Frothers

I-sodium sulfide ngokwayo ayinayo ipropathi ekhupha amagwebu, kodwa inokuchaphazela iipropati ze-pulp kunye nesimo somphezulu weeminerali, ngaloo ndlela ibe nefuthe kwimpembelelo ye-foaming ye-frothers. Isixa esifanelekileyo se-sodium sulfide yenza umphezulu we-hydrophobicity yeeminerali ulungele, ohambelana nokuqhotyoshelwa kwamaqamza kwiiminerali, ukuphucula umphumo wokungenisa umoya kunye nokuzinza kwe-foam ye-frothers. Nangona kunjalo, ubuninzi be-sodium sulfide iya kusasaza i-slime ecocekileyo kwi-pulp, ikhulise i-pulp viscosity, ibangele ukuba i-foam ibe yinto encamathelayo, kwaye ichaphazele ukuzinza kunye ne-fluidity ye-foam, engabandakanyi ukukhuhla i-foam ye-flotation kunye nokwahlulwa kwe-concentrate.

Ukusebenzisana nabanye abaLawuli

I-Synergistic Effect ene-pH Regulators

I-Sodium sulfide hydrolyzes ibe yi-alkaline kwaye inokusebenza ngokubambisana nezinye izilawuli ze-pH ezifana nelayimu kunye ne-sodium ICarboni-ate ukuze ilungelelanise ixabiso le-pH yepulp. Umzekelo, xa i-lead-zinc ore ijikeleza, i-sodium sulfide kunye nelayimu zihlala zisetyenziswa kunye ukugcina i-pulp i-alkaline, ukuthintela ukungcola kweeminerali ezifana ne-pyrite, kunye nokuphucula ukukhetha i-lead-zinc ore kwi-flotation.

Ukusebenzisana neDepressants

I-sodium sulfide ineempembelelo ezifanayo zokuthintela kwezinye izinto ezidakumba njenge i-cyanide kunye neglasi yamanzi. Kwezinye iimeko, zinokusetyenziswa ngokudibeneyo ukunyusa umphumo wokuthintela. Ngokomzekelo, kwi-flotation ye-copper-lead-zinc polymetallic ore, ukusetyenziswa okuhlangeneyo kwe-sodium sulfide kunye ne-cyanide kunokomeleza ukuvinjelwa kwe-sphalerite kunye ne-pyrite, ukufezekisa ukuhlukana okusebenzayo kobhedu-lead kwi-zinc-sulfur. Nangona kunjalo, ingqwalasela kufuneka ihlawulwe ekulawuleni umthamo kunye nolandelelwano lokongeza; ngaphandle koko, ukuvinjelwa okugqithisileyo kunokwenzeka, okuchaphazela izinga lokubuyisela.

Ukusebenzisana ne-Activators

I-sodium sulfide inefuthe lokuvula kwezinye iiminerali ezithintelweyo kwaye ingasetyenziswa ngokudibeneyo kunye ne-activators. Ngokomzekelo, ekuhlukaneni kwe-flotation ye-sulfide yobhedu-lead ore, i-galena evinjwe yi-cyanide inokuthi isebenze nge-sodium sulfide kwaye iqokelelwe yi-ethyl thionocarbamate ukufezekisa ukuhlukana kobhedu kunye nelothe. Ngexesha elifanayo, i-sodium sulfide inokuchaphazela umphumo wezinye ii-activators. Umzekelo, ubuninzi be-sodium sulfide inokutya ii-ion ezisebenzayo kwi-pulp, ukunciphisa umphumo wokusebenza kwee-activators.

Ukuqukumbela, ukuqonda ukusebenzisana kwe-sodium sulfide kunye nezinye ii-reagents kwinkqubo ye-flotation kubaluleke kakhulu ekuphuculeni inkqubo ye-flotation, ukuphucula izinga lokubuyisela kunye nebakala leeminerali ezixabisekileyo, kunye nokunciphisa iindleko zokulungiswa kwezimbiwa. Iinjineli zokulungisa izimbiwa kufuneka zilungelelanise ngononophelo umthamo kunye nolandelelwano lokongezwa kwee-reagents ezahlukeneyo ngokweempawu ezithile zentsimbi ekrwada ukufezekisa ezona ziphumo zibalaseleyo zokudada.
