Tilmaamaha Dhameystiran ee Reagennada Dabaylaha ee Sabbaynta Macdanta

Dib-u-hagaajinta sabbeynta ayaa lama huraan u ah kala soocida macdanta qaaliga ah ee naxaasta iyo dhagaxa wasakhda ah inta lagu jiro habka sabbeynta. Hadafka aasaasiga ah ee sabbeynta naxaasta waa in la soo saaro xooga naxaasta ah oo la iibsan karo. Si taas loo gaaro, reagents kala duwan ayaa loo isticmaalaa, sida caadiga ah loo kala saaraa afar qaybood oo waaweyn: aruuriyayaal, frothers, wax ka beddelayaasha pH, iyo kala firdhiyey.

1. Guryaha Sabaynta Naxaasta

Ururiyayaashu waxay door muhiim ah ka ciyaaraan sabbeynta naxaasta iyagoo ku dhejinaya dusha macdanta naxaasta, iyaga oo ka dhigaya hydrophobic. Tani waxay u oggolaanaysaa macdanta naxaasta inay u hoggaansamaan xumbo hawada oo ay u kacaan dusha sare ee unugga sabbeynta. Soo-ururinta caadiga ah ee sabbeynta naxaasta waxaa ka mid ah xanthates iyo dithiophosphates (reagents madow).

• Xanthates
  Xanthates sida ethyl xanthate iyo pentyl xanthate ayaa si weyn loo isticmaalaa ururiyaha sabbaynta naxaasta. Waxay si wax ku ool ah u galiyaan dusha sare ee macdanta naxaasta ah, iyaga oo ka dhigaya hydrophobic oo sidaas darteed si sahlan loogu dhejiyo goobooyin hawo ah oo ku jira unugga sabbeynta.

• Dithiophosphates (Black Reagents)
  Dithiophosphate reagents sida sodium diisobutyl dithiophosphate (black sodium reagent) iyo ammonium diisobutyl dithiophosphate (madow ammonium reagent) ayaa sidoo kale caadi ahaan loo isticmaalaa. Waxay u shaqeeyaan si la mid ah iyagoo kor u qaadaya hydrophobicity ee macdanta naxaasta ah, fududaynta sabbeynta hufan.

2.Fothers for Copper Flotation

Frothers waxaa lagu daraa unugyada sabbeynta si ay u abuuraan xumbo xasiloon oo u qaada macdanta naxaasta ah ee hydrophobic si kor loogu qaado unugga dushiisa, halkaas oo laga saari karo.

• Saliida geed
  Saliidda Pine waa mid ka mid ah maraqyada inta badan la isticmaalo. Waxay samaysaa lakab maraq deggan oo keenaya macdanta naxaasta ah dusha sare si loo ururiyo.

• Methyl Isobutyl Carbinol (MIBC)
  MIBC waa faleebo kale oo caan ah, oo loo yaqaan sifooyin xumeyn oo heer sare ah iyo xasillooni, taas oo wanaajisa waxtarka sabbeynta.

• Polyether Frothers
  Iskudhisyada Polyether-ka sida polyetylen glycol iyo polypropylene glycol ayaa sidoo kale loo isticmaalaa sabbeynta naxaasta. Barothers-yadani waxay bixiyaan xumbo xasiloon waxayna taageeraan waxqabadka sabbaynta wanaagsan.

3. Wax ka beddelayaasha pH ee Sabaynta Naxaasta

Wax ka beddelayaasha pH waxay nidaamiyaan xaaladaha kiimikaad ee qulqulka sabbaynaya si loo kordhiyo soo kabashada maarta. Wax ka beddelayaasha pH ee caadiga ah waxaa ka mid ah lime, sodium hydroxide, iyo sulfuric acid.

• Lime iyo Sodium Hydroxide
  Lime iyo sodium hydroxide ayaa loo isticmaalaa in lagu hagaajiyo pH-ka dareeraha ah, hagaajinta waxqabadka sabbeynta naxaasta. Xakamaynta pH ee saxda ah waxay lagama maarmaan u tahay sabbeynta xulashada ee naxaasta ee macdanta kale.

• Kahortagayaasha iyo Dhaqdhaqaaqayaasha
  Kahortagga sida Sodium cyanide iyo ferrous sulfate ayaa loo isticmaalaa si looga hortago macdanta aan loo baahnayn inay sabeeyaan, hagaajinta xulashada sabbeynta naxaasta. Dhaqdhaqaaqayaasha, sida copper sulfate, ayaa loo isticmaalaa si kor loogu qaado sabbeynta macdanta copper sulfide.

4. Kala firdhiya sabbaynta naxaasta

Kala firdhisyadu waxay hagaajiyaan qaybinta reagents iyo qaybo adag oo ku jira slurry sabbeynta, hubinta xidhiidhka ka dhexeeya macdanta naxaasta iyo reagents sabbeynta.

• polyacrylamides
  Polyacrylamide waa firdhiye si weyn loo isticmaalo oo ka caawisa ka hortagga isu-ururinta walxaha, hubinta isdhexgalka reagent hufan iyo sabbaynaya naxaasta.

• Resins Epoxy
  Xabagta Epoxy ayaa sidoo kale lagu dabaqaa iyadoo ay ugu wacan tahay kala firdhintooda aadka u wanaagsan iyo sifadooda koolada, taasoo kor u qaadeysa habka sabbeynta guud.
