Falanqaynta kooban ee doorka sulfate copper ee ka faa'iidaysiga macdanta iyo sabbaynta

Copper sulfate, oo u muuqda sida kiristaalo buluug ama buluug-cagaaran, waa firfircooni si weyn loo isticmaalo sabbeynta macdanta sulfide.Inta badan waxaa loo isticmaalaa sida firfircooni, nidaamiye iyo xannibaado si loo hagaajiyo qiimaha pH ee slurry, xakameynta jiilka xumbo iyo hagaajinta Awoodda dusha sare ee macdanta ayaa saameyn firfircoon ku leh sphalerite, stibnite, pyrite iyo pyrrhotite, gaar ahaan sphalerite kaas oo la xakameynayo lime ama cyanide.

Doorka copper sulfate ee sabbaynta macdanta:

1. Waxa loo adeegsaday firfircooni ahaan

Wuxuu bedeli karaa sifooyinka korantada ee dusha macdanta wuxuuna ka dhigi karaa sagxadaha macdanta hydrophilic.Biyo-mareenkan waxa uu kordhin karaa xidhiidhka u dhexeeya macdanta iyo biyaha, taas oo sahlaysa in macdantu ay sabbayso.Copper sulfate waxa kale oo ay ka samaysan kartaa cations slurry macdanta, kuwaas oo lagu sii daayo oogada sare ee macdanta, taas oo kordhinaysa biyo-mareenkeeda iyo kacsanaanta.

Habka hawlgelinta waxa ka mid ah laba dhinac oo soo socda:

①Dareen-celinta metathesis-ku waxay ku dhacdaa dusha sare ee macdanta firfircoon si ay u sameyso filim firfircoon.Tusaale ahaan, sulfate copper waxaa loo isticmaalaa in lagu dhaqaajiyo sphalerite.Radius-ka ion naxaasta kala duwan waxa uu la mid yahay radius of zinc ions, iyo milanka naxaasta sulfide aad ayuu uga yar yahay kan zinc sulfide.Sidaa darteed, filim sulfide copper ayaa laga samayn karaa dusha sare ee sphalerite.Ka dib marka la sameeyo filimka sulfide copper, waxay si fudud ula falgeli kartaa ururiyaha xanthate, si sphalerite loo hawlgeliyo.

②Marka hore ka saar xannibaadaha, ka dibna samee filim hawlqabad.Marka sodium cyanide ay joojiso sphalerite, ion zinc cyanide deggan ayaa laga sameeyay dusha sare ee sphalerite, iyo ions cyanide copper ayaa ka xasilan marka loo eego ion zinc cyanide.Haddii naxaasta sulfate lagu daro sphalerite slurry in la xakameeyo by cyanide, cyanide radicals ee dusha sare ee sphalerite ah ayaa dhici doona, iyo ions naxaas ah oo lacag la'aan ah ayaa ka falcelin doona sphalerite si ay u sameeyaan filim firfircoon oo ah sulfide copper, taas oo kicinaysa sphalerite.

2. Loo isticmaalo nidaamiye ahaan

Qiimaha pH ee slurry waa la hagaajin karaa.Qiimaha pH ee ku habboon, copper sulfate waxay ka falcelin kartaa ions hydrogen oo ku yaal dusha macdanta si ay u sameeyaan walxo kiimiko ah oo isku dhafan oo ku jira macdanta, kordhinta hydrophilicity iyo buoyancy macdanta, taas oo kor u qaadeysa saameynta sabbeynta macdanta dahabka.

3. Loo isticmaalo ka hortag ahaan

Anions waxa ay ku samaysmi kartaa slurry-ka oo waxa ay ku dami kartaa macdanaha kale ee aan u baahnayn sabaynta,waxana ay hoos u dhigtaa biyo-mareenkooda iyo xamaasadooda,taas oo ka ilaalinaysa in macdanahaas lala sabbeeyo macdanta dahabka ah.Copper sulfate inhibitors ayaa inta badan lagu daraa slurry si ay u ilaaliyaan macdanta aan u baahnayn sabbeynta hoose.

4. Loo isticmaalo sidii wax ka beddelka dusha macdanta

Beddel kiimikaad iyo sifooyinka jirka ee dusha macdanta.Sabbaynta macdanta dahabka, hantida korantada iyo hydrophilicity ee dusha macdanta ayaa ah qodobbada sabbeynta muhiimka ah.Copper sulfate waxay samayn kartaa ion copper oxide ee slurry macdanta, waxay ka falcelisaa ions bir ah oogada sare ee macdanta, waxayna beddeshaa sifooyinka kiimikaad ee dusha sare.Copper sulfate waxay sidoo kale bedeli kartaa hydrophilicity ee meelaha macdanta waxayna kordhisaa aagga xiriirka u dhexeeya macdanta iyo biyaha, sidaas darteed kor u qaadida saameynta sabbeynta macdanta dahabka.
