Mutengesi weSodium Hydrosulfide (NaHS) South Africa

Chii chinonzi Sodium Hydrosulfide?

Sodium hydrosulphide (NaHS) munyu we sodium wehydrogen sulfide (H₂S), unowanikwa seyero-green solid flakes kana semvura. Inoderedza simba uye inopa sulfide ion (HS⁻, S²⁻) mumvura ine mvura. NaHS ine mashandisirwo akakosha mukugadzirisa zvicherwa: ndiyo inonyanya kuunza sphalerite (zinc sulphide) flotation, sulphidises pamusoro pe oxide copper minerals kuti ikwanise kuyerera ne xanthate collectors, uye inobvisa simbi dzinorema kubva mumvura se sulfides dzesimbi dzisinganyunguduki mu hydrometallurgical uye mine water treatment processes.

Kugadziriswa kweSulphidisation uye Kushanda kweFlotation

Kushandiswa kukuru kweNaHS mukuyerera kwemvura ndeye sulphidization ye copper oxide uye secondary copper minerals (malachite, azurite, chrysocolla, chalcocite, covellite kubva munzvimbo dze leach) kugadzira sulphide surface layer inopindura kune xanthate collectors. Izvi zvakakosha pakugadzirisa transitional uye oxide-zone copper ores dzine minerals dzakakosha dze copper oxide pamwe chete ne primary sulphide copper minerals. NaHS inoshandiswawo kudzorera sulphidize partial oxidised sulphide surfaces muma circuits ekugadzirisa ore yakaora kana kuti partial oxidised, zvichidzoreredza collector adsorption nzvimbo dzakakuvadzwa ne surface oxidation.

Kupa uye Kubata

Terracore Chemicals inopa sodium hydrosulphide muchimiro cheganda rakasimba (mabhegi 25 kg) uye semushonga (IBCs). NaHS inoburitsa gasi reH₂S kana yasangana nemaacid kana pa pH yakaderera — kuchengetwa nekubata kunofanira kuchengetedza NaHS yakaparadzana nemaacid, uye kubata kwese kunofanirwa kunge kuri munzvimbo dzine mhepo yakakwana uye H₂S gasi iri panzvimbo. SDS yakazara uye maitiro ekubata anopiwa nemirairo.
