Sodium Sulfide (Na₂S 60%–62%) Supplier

Chii chinonzi Sodium Sulfide?

Sodium sulfide (Na₂S) pa 60%–62% assay imhando yemunyu usingashandiswi wepamusoro unopa sulfide ion (S²⁻ neHS⁻) mu alkaline aqueous solution. Isosi yakasimba yesulfide kupfuura sodium hydrosulphide (NaHS) kana tichitarisa kuburitswa kwe sulfide ion pa kilogram, uye inoshandiswa mukugadzira zvicherwa kunyanya pakugadzira sulphide ye copper oxide minerals, activation ye zinc sulphide (sphalerite), uye kunaya kwesimbi dzinorema kubva mu hydrometallurgical solutions. Na₂S inopihwa seyero kusvika kutsvuku-tsvuku (zvikurukuru Na₂S·9H₂O kana kuti anhydrous/partial hydrate forms) uye inofanira kunyungudutswa mumvura isati yashandiswa.

Kugadziriswa kweSulphidisation uye Kushanda kweFlotation

Kufanana nesodium hydrosulfide, sodium sulfide inoshandiswa kunyungudutsa pamusoro pe copper oxide uye secondary copper minerals (malachite, azurite, cuprite, chrysocolla) vasati vanyungudutsa ne xanthate collectors. Sulphidisation neNa₂S inogadzira firimu repamusoro re copper sulphide rinopindura kune xanthate collectors, zvichiita kuti zvinyungudutsane ne copper minerals dzisina kunyungudutsa oxide. Kuita uku kunokurumidza pa flotation pH uye nhanho ye sulphidisation inowanzoitwa mu conditioning tank iri kumusoro kwe flotation circuit. Dosage inowanzova 0.5–3 kg/t zvichienderana nehuwandu hwe oxide copper uye rudzi rwe mineral.

Kuwanikwa uye Kuchengetedzeka

Terracore Chemicals inopa sodium sulfide flake (60%–62% Na₂S) mumabhegi e25 kg, madhiramu e50 kg, uye mabhegi e1 MT bulk. Na₂S inofanira kuchengetwa yakaoma uye kure nemaacids - kusangana nemvura ine acid kana acidic inoburitsa gasi reH₂S rine chepfu. Nzvimbo dzekuchengetera nekubata dzinoda mhepo yakakwana uye michina yekuona H₂S. SDS yakazara, mirairo yekubata, uye nzira dzekunyungudutsa zvinopihwa pamwe chete nemirairo yese.
