Mabda 'xakamaynta iyo adeegsiga zinc sulfate-ka

Si loo wanaajiyo xulashada hanaanka loosoosaarin, kor u qaadida saameynta aruurinta iyo wakiilada xubinta, yareynta isugeynta qaybta, iyo hagaajinta xaaladaha slurry ee floration, maamulayaasha waxaa badanaa loo isticmaalaa geedi socodka wax lagu qoro. Ganacsatada habraaca loo diro waxaa ka mid ah kiimikooyin badan. Marka loo eego kaalintooda hanaanka loo qoro, waxaa loo qaybin karaa kuwa xakameeya, kuwa u shaqeeya, isbadaliyayaal dhexdhexaad ah, wakiillo kafaalaqaad, isku-dhafan, iwm.

Inta lagu gudajiro hanaanka freetor, xakameeyayaashu waa wakiilo ka hortegi kara ama yareyn kara xayeysiinta ama ficilka aruuriyaha dusha sare ee macdanta aan micnaha lahayn, oo sameeya filim biyo-galeenka ah dusha sare ee macdanta.

Zinc sulfate waa mid ka mid ah kuwa wax kantaroolka ah ee muhiimka u ah hanaanka freeyration.

Mabda'a xannibay ee zinc sulfate
Soosaarka macdanta, zinc sulfate, lime culfide, sodium sulfide, iwm.

Waa maxay mabda'a xakamaynta ee zinc sulfate?

Badanaa, saamaynta xannibaynta kaliya waxay ka shaqeysaa kaliya alkaline saxarka. Sare ee sareeya, ayaa sii cad cad in wax laga xannibo. Biyaha dhexdeeda, zinc sulfate waxay ka jawaabtaa sida soo socota:

Znso4 = zn (2 +) + si4 (2-)

Zn (2 +) + 2h2o = zn (oh) 2 + 2h (+) [+) waa xarun amphotic ah, kala dirida aashitada oo cusbo la sameeyo.

Zn (oh) 2 + h2so4 = znso4 + 2h2o

Alkaline Media, Hzno2 (-) iyo zno2 (2-) ayaa la soo saaraa, kuwaas oo lagu xayiro macdanta iyo kor u qaadida biyaha ku jirta macdanta macdanta.

Zn (oh) 2 + Nax = nahzno2 + H2o

Zn (oh2 zn zn + 2naoh = na2zno2 + 2h2o

Macdanta macdanta, zinc sulfate guud ahaan looma isticmaalin keligiis sida xannibaadda, laakiin waxaa badanaa loo isticmaalaa isku darka 'culfide', sodium sulfide, iwm. Isku-darka isticmaalka sulfuric acid iyo cyanide wuxuu kor u qaadi karaa saameynta xannibaynta ee ku saabsan sphalerite.

Codsiga zinc sulfate-ka
Zinc Sulfate waa aashito adag oo milix ah oo daciif ah, oo badanaa leh 7 biyo ah oo biyo ah (zns · 7hydrous), shey saafi ah (andydrous), crystal cad, si fudud biyaha u milmaa biyaha. Waxyaabaha zinc sulfate ee xalka ay ka buuxaan waa 29.4%, iyo xalka aqueous waa aashito. . Waxsoosaarka, waxaa badanaa loo isticmaalaa sida 5% xalka aqueous.

Marka zinc sulfate lagu qaso lime, waa wax ku ool ah in la xakameeyo macdanta Wet Sulc Sulfide (zinc strete ama bir isku-dhafan). Qiimaha sareeya ee pH ee slurry, ayaa ka xoog badan wax soosaarka ah ee xannibaadda zinc sulfate macdanta macdanta zinc sulfide.

Waxaa guud ahaan la rumeysan yahay in saameynta xannibidda ee zinc sulfate macdanta zinc sulfide-ka macdanta loo yaqaan 'zinfide sulfide' waxaa sabab u ah adsic-ka zn (oh) (-), ama zno2 (2-) oo laga soo saaray alkaline Media dusha sare ee macdanta zinc sulc sulcides samee filim dareere ah. Waxaana sababay.

Zinc Sulfate mararka qaarkood waxaa lagu qasaa culeys iyo lime. Amarka hoos udhaca ah ee xannibaadda macdanta birta ee sall sall macdanta birta waa: sphalerite> Pyrite> Challeperate> Chalcopyrite> Marcasite> Sidaa darteed, markii aad kala soocayso polytallitic sulmide macdanta, qiyaasta xakamaynta waa in si adag loo xakameeyaa.
