Ukusebenzisana kwe-Sodium Sulfide namanye ama-reagents kwinqubo ye-Flotation

Emkhakheni we Ukucutshungulwa kwamaminerali, i-flotation iyindlela esetshenziswa kabanzi yokuhlukanisa amaminerali abalulekile ku-gange. I-sodium sulfide idlala indima ebalulekile kule nqubo, ikakhulukazi isetshenziselwa ukulungisa inani le-pH le-pulp, i-sulfidize, i-depress, kanye nokuhlubula amaminerali. Ukusebenzelana kwayo ne Abaqoqi, Obhuti, Futhi nabalawuli ziyinkimbinkimbi futhi zinomthelela omkhulu ekusebenzeni kahle nokukhetha kokuntanta.

Ukusebenzelana nabaqoqi

Ithonya kubaqoqi beMinerali ye-Sulfide

Kwabaqoqi abavame ukusetshenziselwa amaminerali e-sulfide anjenge-xanthates ne-dithiophosphates, lapho umthamo I-Sodium sulfide kufanelekile, ingathuthukisa i-hydrophobicity yendawo yamaminerali e-sulfide, ivumele abaqoqi ukuthi bakhangise kangcono endaweni yamaminerali futhi ithuthukise ukuntanta kwamaminerali. Kodwa-ke, lapho i-sodium sulfide ingaphezu kwamandla, izokwakha ifilimu ye-hydrophilic ebusweni bamaminerali e-sulfide, ivimbele ukukhangiswa kwabaqoqi futhi ngaleyo ndlela idlale indima yokuvimbela. Isibonelo, ekuntanteni kwe-ore yethusi-sulfur, inani elifanele le-sodium sulfide lingakhuthaza ukuqoqwa kwe-chalcopyrite nge-xanthate, kuyilapho inani eliningi lizovimbela ukuntanta kwe-chalcopyrite.

Ithonya kubaqoqi beMinerali ye-Oxide

Ekuntanteni kwamaminerali e-oxide, i-sodium sulfide ingasusa i-sulfidize ebusweni bamaminerali e-oxide, iwavumele ukuthi aqoqwe ngabaqoqi bamaminerali e-sulfide. Isibonelo, lapho usebenzisa abaqoqi be-fatty acid ukuze bantante i-cerussite, i-sodium sulfide iqala i-sulfidize ebusweni be-cerussite bese ixhumana nomqoqi we-fatty acid, ithuthukisa umphumela wokuntanta kwe-cerussite.

Ukuxhumana noFrothers

I-sodium sulfide ngokwayo ayinayo impahla ekhihliza amagwebu, kodwa ingathinta izakhiwo ze-pulp kanye nesimo samaminerali, ngaleyo ndlela ibe nomthelela ekuphumeni kwamagwebu. Inani elifanele le-sodium sulfide lenza i-hydrophobicity engaphezulu yamaminerali ifaneleke, evumela ukunamathela kwamabhamuza kumaminerali, ithuthukise umphumela wokungenisa umoya kanye nokuzinza kwegwebu lamagwebu. Kodwa-ke, inani eliningi kakhulu le-sodium sulfide lizohlakaza i-slime enhle ku-pulp, kwandise i-viscosity ye-pulp, kubangele ukuthi igwebu linamathele, futhi lithinte ukuzinza nokumanzi kwegwebu, okungahambisani nokukhuhla igwebu elintantayo kanye nokuhlukaniswa kwe-concentrate.

Ukusebenzisana Nezinye Izilawuli

I-Synergistic Effect ene-pH Regulators

I-Sodium sulfide i-hydrolyzes ibe yi-alkaline futhi ingasebenza ngokubambisana nezinye izilawuli ze-pH ezifana ne-lime ne-sodium I-Carbonukuze kulungiswe ndawonye inani le-pH le-pulp. Isibonelo, ekuntanteni kwe-lead-zinc ore, i-sodium sulfide kanye ne-lime kuvame ukusetshenziswa ndawonye ukugcina i-pulp alkaline, ukuvimbela amaminerali angcolile njenge-pyrite, nokuthuthukisa ukukhetha kwe-flotation kwe-lead-zinc ore.

Ukusebenzelana nama-Depressants

I-sodium sulfide inemiphumela efanayo yokuvimbela kwezinye izidakamizwa ezifana i-cyanide kanye nengilazi yamanzi. Kwezinye izimo, zingasetshenziswa ngokuhlanganyela ukuze kuthuthukiswe umphumela wokuvimbela. Isibonelo, ekuntanteni kwe-copper-lead-zinc polymetallic ore, ukusetshenziswa okuhlangene kwe-sodium sulfide ne-cyanide kungaqinisa ukuvinjelwa kwe-sphalerite ne-pyrite, kufinyelele ukuhlukaniswa okuphumelelayo kwe-copper-lead kusuka ku-zinc-sulfur. Nokho, kufanele kuqashelwe ukulawula umthamo kanye nokulandelana kokwengeza; ngaphandle kwalokho, ukuvinjelwa ngokweqile kungase kwenzeke, kuthinte izinga lokubuyisela.

Ukusebenzisana nama-Activators

I-sodium sulfide inomphumela wokwenza kusebenze kwamanye amaminerali avinjiwe futhi ingasetshenziswa ngokuhambisana nezicupha. Isibonelo, ekuhlukaniseni okuntantayo kwe-sulfide yethusi-lead ore, i-galena evinjwe i-cyanide ingenziwa isebenze nge-sodium sulfide bese iqoqwa yi-ethyl thionocarbamate ukuze kuzuzwe ukuhlukaniswa kwethusi nomthofu. Ngesikhathi esifanayo, i-sodium sulfide ingase futhi ithinte umphumela wezinye izicupha. Isibonelo, inani eleqile le-sodium sulfide lingase lidle ama-ion asebenzayo ku-pulp, linciphise umphumela wokwenza kusebenze ama-activator.

Sengiphetha, ukuqonda ukusebenzisana kwe-sodium sulfide namanye ama-reagents enqubweni ye-flotation kubaluleke kakhulu ekuthuthukiseni inqubo ye-flotation, ukuthuthukisa izinga lokubuyisela kanye nebanga lamaminerali abalulekile, nokunciphisa izindleko zokucubungula amaminerali. Onjiniyela bokucubungula amaminerali badinga ukulungisa ngokucophelela umthamo kanye nokulandelana kokwengezwa kwama-reagents ahlukahlukene ngokuya ngezakhiwo ezithile ze-ore ukuze bathole imiphumela engcono kakhulu yokuntanta.
