Doorka Copper Sulfate ee Wershadaha Ka-hortagga Macdanta

Qaybta adag ee muhiimka ah ee habaynta macdanta , kiimikooyin kala duwan ayaa door muhiim ah ka ciyaara hagaajinta kala soocidda iyo soo saarista macdanta qiimaha leh. Copper sulfate, oo leh sifooyin kiimiko oo kala duwan, ayaa soo ifbaxday inay tahay reagent aad muhiim ugu ah warshadahan. Maqaalkani wuxuu si qoto dheer u eegayaa hawlaha badan ee copper sulfate ee habaynta macdanta, isagoo sahaminaya farsamooyinkeeda iyo adeegsigeeda.

Dhaqdhaqaaqa Macdanta

Mid ka mid ah doorka ugu muhiimsan uguna caansan ee naxaasta sulfate ee farsamaynta macdanta waa shaqadeeda firfircooni ahaan. Tusaale ahaan, macdanta sulfide-ka, sabeynta , waxay leedahay saameyn firfircooni oo cajiib ah oo ku saabsan dhowr macdan sida sphalerite, stibnite, pyrite, iyo pyrrhotite, iyadoo si gaar ah saameyn xooggan ugu leh sphalerite.

Hababka firfircoonida

1. Falcelinta Metathesis si loo Sameeyo Filim Firfircoon

Marka naxaasta sulfate loo isticmaalo in lagu kiciyo sphalerite, falgal metathesis ah ayaa dhaca. Gacanka ion-yada naxaasta ee kala duwan waxay la mid yihiin ion-yada zinc, milmida naxaasta sulfide-na aad ayay uga yar tahay tan zinc sulfide. Natiijo ahaan, lakab filim naxaas sulfide ah ayaa laga samayn karaa dusha sare ee sphalerite. Ka dib marka la sameeyo filimka naxaasta sulfide, si fudud ayuu ula falgeli karaa Ururiyayaasha sida xanthates. Xanthates waxay leeyihiin xiriir xooggan oo naxaasta sulfide ah, taas oo kor u qaadaysa hydrophobicity ee dusha sare ee sphalerite, taasoo sahlaysa in macdantu ay ku dhegto xumbo hawada oo ay sabayso, sidaas darteedna ay kiciso sphalerite.

2.Ka saarida Kahortagayaasha iyo Samaynta Filim Firfircoon

Xaaladaha qaarkood, macdanta waxaa joojin kara walxo kale. Tusaale ahaan, marka Sodium Cyanide loo isticmaalo sidii wax ka hortag ah habka sabbeynta, waxay samayn kartaa ayoonada isku-dhafan ee zinc- cyanide oo deggan dusha sare ee sphalerite, taas oo xakameysa sabbeynta sphalerite. Si kastaba ha ahaatee, ayoonada isku-dhafan ee naxaasta - cyanide ayaa ka xasilloon marka loo eego ayoonada isku-dhafan ee zinc-cyanide. Marka copper sulfate lagu daro slurry-ka sphalerite ee uu joojiyey cyanide, xagjirada cyanide ee dusha sare ee sphalerite way dhacaan, ayoonada naxaasta ee xorta ahna waxay markaa la falgalaan sphalerite si ay u sameeyaan filim firfircoon oo ah sulfide naxaas ah, sidaas darteedna waxay dib u dhaqaajiyaan sphalerite si ay u sabbeeyaan.

Xeerarka slurry pH

Copper sulfate waxa kale oo ay u adeegtaa sidii nidaamiye ee slurry farsamaynta macdanta, gaar ahaan marka la eego hagaajinta pH. Qiimaha pH ee slurry waa arrin muhiim ah oo saameeya sifooyinka dusha sare ee macdanta iyo waxqabadka reagents sabbeynta.

Marka sulfate copper lagu daro slurry, waxay mari kartaa hydrolysis ee biyaha. Aashitada sulfuric ee ka soo baxda waxay kordhin kartaa diiradda hydrogen ion ee slurry, sidaas darteed hoos u dhigista qiimaha pH. Marka la eego qiimaha pH ee ku habboon, sulfate copper waxay ka falcelin kartaa ions hydrogen ee dusha macdanta si ay u sameeyaan walxo kiimiko ah oo isku dhafan oo la socda macdanta. Dareen-celintani waxay kordhin kartaa qulqulka biyaha iyo qulqulka macdanta, kor u qaadista saameynta sabbeynta. Tusaale ahaan, qaar ka mid ah dahabka - macdanta xajinta, hagaajinta pH ee slurry ee leh sulfate copper waxay kor u qaadi kartaa isdhexgalka ka dhexeeya dahabka - macdanta iyo ururiyeyaasha, hagaajinta dib u soo kabashada dahabka.

Joojinta Macdanta Aan La rabin

Marka lagu daro firfircoonida, copper sulfate waxay sidoo kale u shaqeyn kartaa sidii horjooge xaaladaha qaarkood. Habka sabbeynta, inta badan waa lagama maarmaan in la kala saaro macdanta la beegsanayo iyo macdanta kale ee aan loo baahnayn. Copper sulfate waxaa loo isticmaali karaa in lagu joojiyo sabbeynta macdanta aan bartilmaameedka ahayn.

Marka lagu daro slurry, copper sulfate waxay sameyn kartaa anions kuwaas oo lagu dhejiyo dusha macdanta kale ee aan u baahnayn sabbeynta. Xayeysiintu waxa ay yaraynaysaa biyo-mareenka iyo kacsanaanta macdantan aan bartilmaameedka ahayn, iyada oo ka ilaalinaysa in lala sabbeeyo macdanta la beegsanayo. Tusaale ahaan, nidaamka sabbeynta oo ujeedadu tahay in la kala saaro macdanta dahabka ah ee macdanta gangue qaarkood, ku darida xakamaynta copper sulfate ee slurry waxay ku hayn kartaa macdanta gangue ee hoose ee unugga sabbeynta iyada oo u oggolaanaysa macdanta dahabka ah inay sabbayso dusha sare iyada oo la kaashanayo kuwa aruuriya iyo goobooyin.

Wax ka beddelka dusha sare ee macdanta

Copper sulfate wuxuu u dhaqmi karaa sidii wax ka beddelka dusha macdanta, beddela kiimikooyinka iyo sifooyinka jirka ee meelaha macdanta. Sabbaynta macdanta dahabka, hantida korantada iyo hydrophilicity ee dusha macdanta ayaa ah arrimo muhiim ah oo saameeya waxtarka sabbeynta.

Isku-dhafka macdanta, sulfate copper wuxuu sameyn karaa naxaas - oo ay ku jiraan ions. Iions-yadani waxay kaga falcelin karaan ion bir ah oo ku yaal dusha sare ee macdanta, iyagoo beddelaya sifooyinka kiimikaad ee dusha sare. Tusaale ahaan, korka dahabka qaar ka mid ah - macdanta sida lakabka oksaydh gaar ah, copper - ka kooban ions waxa ay la falgali karaan aions biraha lakabka oksaydh, samaynta xeryahooda cusub kiimika on dusha. Tani waxay bedeli kartaa kharashka dusha sare iyo falcelinta kiimikada macdanta.

Intaa waxaa dheer, copper sulfate waxay sidoo kale saameyn kartaa hydrophilicity ee meelaha macdanta. Kordhinta aagga xidhiidhka u dhexeeya macdanta iyo biyaha, waxay hagaajin kartaa kala firdhisanaanta macdanta ku jirta slurry. Kala firdhintan la xoojiyey waxay faa'iido u yeelan kartaa tallaabada xigta ee ururiyeyaasha. Marka wax soo uruuriyayaashu lagu daro, waxay si wax ku ool ah ula falgali karaan sagxadaha macdanta ee la beddelay, kor u qaadista ku-xidhka macdanta ee xumbo hawada iyo ugu dambeyntii hagaajinta saameynta sabbeynta macdanta dahabka.

Ugu Dambeyn

Marka la soo koobo, sulfate copper waxa uu ka ciyaaraa door kala duwan oo lama huraan ah warshadaha warshadaynta macdanta. Dhaqdhaqaaq ahaan, waxay si weyn u wanaajin kartaa waxqabadka sabbeynta macdanta sida sphalerite iyadoo la samaynayo filimo firfircooni ama ka saarista xannibaadayaasha. Xakameyn ahaan, waxay gacan ka geysataa hagaajinta pH-ka-slurry, taas oo muhiim u ah shaqeynta saxda ah ee habka sabbeynta. Sida horjooge, waxay si xushmad leh uga hortagi kartaa sabbeynta macdanta aan loo baahnayn, hagaajinta nadiifinta xoogga ugu dambeeya. Iyo sida wax ka beddelka dusha sare ee macdanta, waxay bedeli kartaa kiimikada iyo sifooyinka jirka ee meelaha macdanta, kor u qaadida isdhexgalka ka dhexeeya macdanta iyo reagents sabbeynta. Isticmaalka saxda ah ee sulfate copper ee farsamaynta macdanta ma aha oo kaliya hagaajinta waxtarka kala-soocidda macdanta laakiin sidoo kale waxay gacan ka geysataa isticmaalka joogtada ah iyo dhaqaalaha ee khayraadka macdanta.
