Izinsalela ze-Oxide zithinta kanjani amazinga okuphuma kwe-Flotation ye-Copper Sulphide?

Isikhathi:13 Novemba 2025

Izinsimbi ze-oxide zingabonakalisa umthelela omkhulu ezingeni lokubuyiswa kwe-flotation ye-copper sulfide, ikakhulukazi ngenxa yezinhlobonhlobo ezihlukahlukene kwezimo zabo ze-mineralogical kanye nekhemistry ye-surface. Nansi isishwankathelo sokuthi izinsimbi ze-oxide zithinta kanjani inqubo ye-flotation ye-copper sulfide:

1. Ukushintsha kweKemistri Yendawo:

   • Izim mineral ze-copper oxide, ezifana ne-malachite, azurite, noma i-cuprite, zidinga izinto ezahlukene zokuphendula nezimo zokuhluza uma kuqhathaniswa nezim mineral ze-sulfide (isb., i-chalcopyrite noma i-bornite).
   • Uma ama-oxide ores ekhona, angaphazamisa ukufaka umoya kumaminerali e-sulfide ngokudla izithasiselo (isb., abaqoqi nabafuthumizi) noma ngokushintsha kimayela ye-pulp, okwehla umphumela phakathi kwabazalayo nezinsiza ze-sulfide.

2. Izinkinga Zokuhlanganiswa Kwamaminerali (Amaminerali Acomplex)

   • Ezindaweni eziningi, izinsalela zethusi ziqukethe inhlanganisela ye-oxide kanye nezimfanelo ze-sulfide. Ukuhlanzwa kwama-sulfide kuvamile ukuthi kube lula kune-oxide, ezivame ukuba ne-hydrophilic ngokwemvelo futhi zidinga ukwelashwa okwengeziwe ukuze zibe ne-hydrophobic.
   • Ukuba khona kwe-oxides kunganciphisa okuqukethwe kwe-sulfide emgodleni, ngaleyo ndlela kunciphisa izinga lokubuyiselwa kwe-copper sulfides ngaphandle kokuthi izinqubo ezithile zithatheka.

3. Ukusetshenziswa Kwezithako:

   • Amaminerali e-oxide ajwayele ukusebenzisa izinga eliphezulu labakhethi kanye nochwepheshe ukuze kuthuthukiswe ukuflotation kwawo. Lokhu kungaholela ekusetshenzisweni okungasebenzi kahle kwezithako zokusebenza futhi kunciphise ukusebenza kahle kwe-flotation ye-sulfide.
   • Ezimweni ezithile, amakhona engeziwe e-copper hydroxides noma ama-oxides angakha izigcwalibhu ema-minerali e-sulfide, ehambisa phansi ukusebenza kokuphumelelayo kokuhlola i-sulfides.

4. Ukuncika kwe-pH:

   • Ngesikhathi sokuphakanyiswa, i-pH ye-slurry ivamise ukulungiswa ukuze kuzuze ukuphathwa kwe-sulfide okuhle. Nokho, ukumelana kokuphakanyiswa kwe-copper oxides kungase kudinge izimo ezihlukile ze-pH, okuholela ekuxhumaneni okwehlisa ukuphathwa kwe-sulfide.

5. Uk tratamento ngaphambi kokufaka emanzini:

   • Ukuze kuncishiswe umthelela wezinsimbi ze-oxide, izinyathelo zokulungiselela ezifana nokufaka i-sulfidization zivame ukufakwa. Kule nqubo, izinsimbi ze-oxide ziphathwa ngama-agent afana ne-sodium sulfide noma i-ammonium sulfide ukuze ziguqulwe zibe izinsimbi ezifanayo ne-sulfide, okwenza ukufuthwa kwazo kube kuhlelekile neziqu zefuthwe. Nokho, lokhu kukhuphula ubunzima nezindleko kwezok обработку.

6. Uk形成 kweSlime nokungena:

   • Amaminerali e-oxide kanye nezinguquko zawo ezithambile zingakha ama-slime ngesikhathi sokugaya. Lezi zinsalela ezincane zingakha uqweqwe phezu kw surface yamaminerali e-sulfide noma zandise i-viscosity ye-slurry, ngaleyo ndlela zithinte ukusebenza kahle kokuhlanza nokwehlisa izinga lokubuyiselwa.

7. Izindlela Zokubuyiselwa:

   • Izinga lokubuyiselwa kwe-sulfide elibi ngenxa yokungcoliswa kwe-oxide ngokuvamile lincike ezindlela zokucubungula. Intuthuko ekuthuthukisweni kwemithombo, i-hydrometallurgy, noma izindlela zokuhlukanisa/ukuhlukanisa ze-bulk flotation zingasiza ekunciphiseni le miphumela.

Ngamafuphi, ama-oxide ores ngokuvamile anciphisa izinga lokubuyiswa kokukhanyisa kwemali ephelile ngensalela, ngokuphazamisa ikhhemikhali yenqubo ngokwanda kokusetshenziswa kwezinto ezisebenzayo, izimo ezishintshile ze-slurry, nokuphazamiseka kokukhanyisa okhethekile. Ukulwisana nale miphumela, izimboni zokucubungula ngokuvamile zisebenzisa amasu athile aphonsela phansi, zisebenzisa izinto ezithuthukisiwe, noma zamukela izindlela zokukhipha ezihlukile ezihlelwe ukuze zifanele ama-ore ahlanganisiwe noma ayinkimbinkimbi.
