Farsamooyinka kala duwan ee la isticmaalo, Flotation waa mid ka mid ah hababka ugu badan ee la isticmaalo. Habkan, Ammonium sulfate wuxuu door muhiim ah ka ciyaaraa, isagoo gacan ka geysanaya kala soocidda hufan iyo soo kabashada macdanta. Maqaalkani wuxuu sahamin doonaa hawlaha badan ee ammonium sulfate ee habaynta macdanta , isagoo eegaya farsamooyinkeeda iyo adeegsigeeda.

Astaamaha Ammonium Sulfate

Ammonium sulfate waa crystalline cad oo adag. Waxay si fudud ugu milmaysaa biyaha, taas oo ah sifo muhiim ah oo loogu talagalay codsiyadeeda diyaarinta macdanta. Xaaladaha caadiga ah, xaruntu waxay leedahay qaab dhismeed kiimiko ah oo deggan. Laakiin marka lagu soo bandhigo jawiga macdanta, waxay ka qayb qaadan kartaa falcelin kiimikaad oo kala duwan.

Hawlaha ku jira sabbeynta

Dhiirri-qaate ahaan

Habka sabbaynta, ururiyeyaashu waa walxo si door ah ugu dhejiya dusha sare ee macdanta bartilmaameedka ah, iyaga oo ka dhigaya hydrophobic oo awood u siinaya inay kala soocaan sabbeynta maraq. Ammonium sulfate waxay kor u qaadi kartaa isdhexgalka ka dhexeeya kuwa wax ururiya iyo macdanta. Tusaale ahaan, sabbeynta macdanta sulfide qaarkood, ammonium sulfate waxay ka falcelin kartaa dusha macdanta, wax ka beddeleysa sifooyinka kiimikada. Dib-u-habayntani waxay kor u qaadaysaa soo-ururinta, sida xanthates, oogada macdanta. Ayoonooyinka ku jira ammonium sulfate waxay la falgali karaan ion birta ah oogada macdanta, samaynta dhismo ama beddelaan kharashka dusha sare. Isbeddelkan ku yimaadda guryaha dusha sare wuxuu kordhiyaa xidhiidhka ka dhexeeya ururiyaha iyo macdanta, hagaajinta waxtarka kala-soocidda macdanta.

Sida hagaajinta pH ahaan

Qiimaha pH ee saxarka sabbaynaya waa arrin muhiim ah oo saameeya habdhaqanka sabbeynta macdanta. Ammonium sulfate wuxuu u dhaqmi karaa sidii hagaajinta pH xaaladaha qaarkood. Marka lagu milmo biyaha, ammonium sulfate waxa ay martaa hannaan kiimiko oo soo daaya ion hydrogen, kaas oo wax yar ka dhigaya saxarka. Sabbaynta macdanta qaar ka mid ah, sida macdanta oksaydhka qaarkood, pH gaar ah ayaa looga baahan yahay sabbaynta ugu fiican. Adigoo hagaajinaya pH leh ammonium sulfate, sifooyinka dusha sare ee macdanta waa la bedeli karaa.
