Ukusebenzisana kweSodium Sulfide kunye nezinye iiReagents kwiNkqubo yeFlotation

Kwicandelo lokucubungula izimbiwa , i-flotation yindlela esetyenziswa kakhulu yokwahlula izimbiwa ezixabisekileyo kwi-gangue. I-sodium sulfide idlala indima ebalulekileyo kule nkqubo, ikakhulu isetyenziselwa ukulungisa ixabiso le-pH ye-pulp, i-sulfidize, icinezele, kwaye isuse umphezulu wezimbiwa. Ukusebenzisana kwayo neCollectors , Frothers , kunye neRegulators kuyinkimbinkimbi kwaye kuchaphazela kakhulu ukusebenza kakuhle kunye nokukhetha kwe-flotation.

Ukusebenzisana nabaqokeleli

Impembelelo kubaqokeleli beMineral yeSulfidi

Kwizinto ezisetyenziswa rhoqo ekuqokeleleni iiminerali ze-sulfide ezifana nee-xanthates kunye nee-dithiophosphates, xa idosi ye -Sodium sulfide ifanelekile, inokunyusa ukunganyamezeli kwamanzi kumphezulu weminerali ye-sulfide, ivumele abaqokeleli ukuba banamathele ngcono kumphezulu weminerali kwaye baphucule ukuntanta kweeminerali. Nangona kunjalo, xa i-sodium sulfide ininzi, iya kwenza ifilimu ethanda amanzi kumphezulu weminerali ye-sulfide, ithintele ukufunxwa kwabaqokeleli kwaye ngaloo ndlela idlale indima yokuthintela. Umzekelo, ekuntanteni kwe-copper-sulfur ore, isixa esifanelekileyo se-sodium sulfide sinokukhuthaza ukuqokelelwa kwe-chalcopyrite yi-xanthate, ngelixa isixa esigqithisileyo siya kuthintela ukuntanteka 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 i-hydrolyzes ibe yi-alkaline kwaye inokusebenza ngokubambisana nezinye izilawuli ze-pH ezifana nelayimu kunye ne-sodium Carbon ate ukuze kulungiswe ixabiso le-pH ye-pulp. Umzekelo, ekujikelezeni kwe-lead-zinc ore, i-sodium sulfide kunye nelayimu zihlala zisetyenziswa ngokudibeneyo ukugcina i-pulp alkaline, ukuthintela ukungcola kweeminerali ezifana ne-pyrite, kunye nokuphucula ukukhetha kwe-flotation ye-lead-zinc ore.

Ukusebenzisana neDepressants

I-Sodium sulfide ineziphumo ezifanayo zokuthintela ezinye izinto ezidambisayo ezifana ne -cyanide kunye neglasi yamanzi. Kwezinye iimeko, zingasetyenziswa ngokudibeneyo ukuphucula isiphumo sokuthintela. Umzekelo, ekujikelezeni kwe-copper-lead-zinc polymetallic ore, ukusetyenziswa okudibeneyo kwe-sodium sulfide kunye ne-cyanide kunokuqinisa ukuthintelwa kwe-sphalerite kunye ne-pyrite, kufezekiswe ukwahlula okusebenzayo kwe-copper-lead kwi-zinc-sulfur. Nangona kunjalo, kufuneka kunikwe ingqalelo ekulawuleni idosi kunye nolandelelwano lokongeza; kungenjalo, ukuthintelwa okugqithisileyo kunokwenzeka, okuchaphazela izinga lokubuyela kwimeko yesiqhelo.

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.
