Sodium Sulfide (Na₂S 60%–62%) Supplier

Iyini i-Sodium Sulfide?

I-Sodium sulfide (Na₂S) ekuhlolweni okungu-60%–62% usawoti ongaxubile wezinga lobuchwepheshe ohlinzeka nge-sulfide ion (S²⁻ kanye ne-HS⁻) kusisombululo samanzi se-alkaline. Ungumthombo we-sulfide onamandla kune-sodium hydrosulphide (NaHS) ngokwe-sulfide ion ekulethwa ngekhilogramu, futhi isetshenziswa ekucubungulweni kwamaminerali ikakhulukazi ekufakweni kwe-sulphide yamaminerali e-copper oxide, ukusebenza kwe-zinc sulphide (sphalerite), kanye nokukhipha izinsimbi ezisindayo ezivela ezixazululweni ze-hydrometallurgical. I-Na₂S inikezwa njengama-flakes aphuzi kuya kubomvu-nsundu (ikakhulukazi ama-non-hydrate Na₂S·9H₂O noma ama-anhydrous/partial hydrate) futhi kumele incibilikiswe emanzini ngaphambi kokusetshenziswa.

Ukusebenza kwe-Sulphidisation kanye ne-Flotation

Njenge-sodium hydrosulfide, i-sodium sulfide isetshenziselwa ukuxubha ubuso be-copper oxide kanye namaminerali esibili ethusi (i-malachite, i-azurite, i-cuprite, i-chrysocolla) ngaphambi kokuxubha nabaqoqi be-xanthate. I-Sulphidisation ene-Na₂S idala ifilimu elincane le-copper sulfide surface eliphendula kubaqoqi be-xanthate, okwenza kube nokuxubha kwamaminerali ethusi e-oxide angantantayo. Ukusabela kuyashesha ku-flotation pH futhi isinyathelo se-sulphidisation ngokuvamile senziwa ethangini lokulungisa phezulu kwesekethe yokuxubha. Isilinganiso ngokuvamile singu-0.5–3 kg/t kuye ngokuqukethwe kwe-oxide copper kanye nohlobo lwamaminerali.

Ukunikezwa Nokuphepha

I-Terracore Chemicals inikeza i-sodium sulfide flake (60%–62% Na₂S) ezikhwameni ezingama-25 kg, izigubhu ezingama-50 kg, kanye nezikhwama ezinkulu ezingama-1 MT. I-Na₂S kumele igcinwe yomile futhi ikude nama-asidi — ukuthintana namanzi angcolile ane-asidi noma ane-asidi kukhiqiza igesi enobuthi ye-H₂S. Izindawo zokugcina nokuphatha zidinga umoya owanele kanye nemishini yokuthola i-H₂S. I-SDS ephelele, imiyalelo yokuphatha, kanye nezinqubo zokuhlakazeka zinikezwa nazo zonke izi-oda.
