Waa maxay tilmaamaha guud ee zinc sulfate ee farsamaynta macdanta iyo mabda'a shaqada?

Doorka ugu weyn ee zinc sulfate ee farsamaynta macdanta waa in la doorto macdanta zinc iyo iska caabinta macdanta zinc-ku jirta.Caadi ahaan, waxay leedahay iska caabin ka fiican slurry alkaline.Qiimaha pH ee sarreeya ee slurry, ayaa si cad u muuqda caabbinta, taas oo faa'iido u leh habka macdanta.Sidoo kale waa walxo macdaneed oo si caadi ah loo isticmaalo oo leh qiimo jaban iyo saameyn wanaagsan.Waa shay lagama maarmaan u ah farsamaynta macdanta.
Mabda'a ficilka zinc sulfate: Zinc sulfate saafi ah waa crystal cad, si sahal ah ugu milmi biyaha, waana ka hortagga sphalerite.Caadi ahaan waxay leedahay oo kaliya saamaynta xannibista ee dareeraha alkaline.Markasta oo uu sareeyo pH-da dheecaanku, waa ay sii caddahay saamaynteeda xakamaynta..Zinc sulfate waxay soo saartaa falcelinta soo socota ee biyaha:
ZnSO4＝Zn2++SO42-
Zn2++2H20=Zn(OH)2+2H+
Zn(OH)2 waa iskudhis amphoteric ah oo ku milma aashitada si ay u samaysato milix.
Zn(OH)2+H2S04＝ZnSO4+2H2O
Dhexdhexaadinta alkaline, HZnO2- iyo ZnO22- ayaa la helay.Laydhkooda macdanta ayaa kor u qaadaya biyo-mareenka meelaha macdanta ah.
Zn(OH)2+NaOH=NaHZnO2+H2O
Zn(OH)2+2NaOH=Na2ZnO2+2H2O
