Is-dhexgalka Sodium Sulfide iyo Reageniyeyaasha kale ee Geedi-socodka Sabaynta

Qeybta farsamaynta macdanta, sabayntu waa hab aad loo isticmaalo oo lagu kala saaro macdanta qiimaha leh iyo gangue. Sodium sulfide ayaa door muhiim ah ka ciyaara habkan, inta badan waxaa loo isticmaalaa in lagu hagaajiyo qiimaha pH ee saxarka, sulfidize, niyad-jabka, iyo in laga saaro dusha macdanta. Is dhexgalka ay la leedahay Aruuriyaha, Walaalayaal, Iyo Xeer-dejiyeyaasha waa kuwo adag oo si weyn u saameeya waxtarka iyo xulashada sabbeynta.

Saamaynta Ku-Xigeennada Macdanta Sulfide

Uruurinta sida caadiga ah loo isticmaalo macdanta sulfide sida xanthates iyo dithiophosphates, marka qiyaasta Sodium sulfide waa ku habboon tahay, waxay kor u qaadi kartaa hydrophobicity ee dusha macdanta sulfide, awood ururinta si ay u adsorb si fiican on dusha macdanta iyo hagaajinta floatability ee macdanta. Si kastaba ha noqotee, marka sodium sulfide ay ka badan tahay, waxay sameyn doontaa filim hydrophilic oo ku yaal dusha sare ee macdanta sulfide, taas oo caqabad ku ah xayeysiinta kuwa wax ururiya oo sidaas darteed ciyaaraya door xannibaad ah. Tusaale ahaan, sabbeynta macdanta copper-sulfur, qadar ku habboon oo sodium sulfide ah ayaa kor u qaadi karta ururinta chalcopyrite by xanthate, halka qadarka xad-dhaafka ah uu joojin doono sabbeynta chalcopyrite.

Saamaynta Ku-ururinta Macdanta Oxide

Sabbaynta macdanta oksaydhka, sodium sulfide waxay sulfidize kartaa dusha sare ee macdanta oksaydhka, taas oo u oggolaanaysa in ay soo ururiyaan macdanaha sulfide. Tusaale ahaan, marka la isticmaalayo ururiyeyaasha dufanka dufanka leh si ay u sabeeyaan cerussite, sodium sulfide ayaa marka hore sulfidizes dusha sare ee cerussite ka dibna la falgala ururiyaha dufanka leh, hagaajinta saamaynta sabbeynta cerussite.

Is dhexgalka Frothers

Sodium sulfide lafteedu ma laha hanti xumbo, laakiin waxay saamayn kartaa sifooyinka saxarka iyo xaaladda dusha sare ee macdanta, taas oo saameyn ku yeelanaysa saameynta xumbo-baxa. Qadarka saxda ah ee sodium sulfide wuxuu ka dhigayaa dusha sare ee hydrophobicity ee macdanta ku habboon, taas oo ku habboon ku dhejinta xumbooyinka macdanta, hagaajinta saameynta hawada iyo xasilloonida xumbo ee frothers. Si kastaba ha ahaatee, xaddi xad-dhaaf ah oo sodium sulfide ah waxay kala firdhisaa dhoobada wanaagsan ee saxarka, waxay kordhisaa viscosity saxarka, waxay keenaysaa xumbo-ku-dheg, waxayna saamaysaa xasilloonida iyo dheecaanka xumbo, taas oo aan ku habboonayn xoqidda xumbo sabbeynta iyo kala-soocidda xoogga.

Isdhexgalka Maamulayaasha Kale

Saamaynta Isku-dhafan ee leh pH Regulators

Sodium sulfide hydrolyzes si ay u noqoto alkaline waxayna si wada jir ah ula dhaqmi kartaa nidaamiyeyaasha pH kale sida lime iyo sodium carbonate si wadajir ah loogu hagaajiyo qiimaha pH ee saxarka. Tusaale ahaan, sabbeynta macdanta macdanta "lead-zinc", sodium sulfide iyo lime ayaa inta badan loo isticmaalaa isku darka si loo ilaaliyo saxarka alkaline, la joojiyo macdanta wasakhda ah sida pyrite, iyo hagaajinta xulashada sabbeynta ee macdanta macdanta "lead-zinc".

Is dhexgalka lala yeesho daaweeyayaasha

Sodium sulfide waxay leedahay saameyn la mid ah kuwa ka hortagga niyad-jabka sida cyanide iyo galaas biyo ah. Xaaladaha qaarkood, waxaa loo isticmaali karaa si wadajir ah si kor loogu qaado saameynta xannibaadda. Tusaale ahaan, sabbeynta naxaasta-lead-zinc-polymetallic ore, isticmaalka isku-dhafka ah ee sodium sulfide iyo cyanide waxay xoojin kartaa xakameynta sphalerite iyo pyrite, gaaritaanka kala-soocidda wax ku oolka ah ee macdanta-lead-ka zinc-sulfur. Si kastaba ha ahaatee, waa in fiiro gaar ah loo yeesho xakamaynta qiyaasta iyo isku xigxiga; haddii kale, xannibaad xad-dhaaf ah ayaa laga yaabaa inay dhacdo, taasoo saameynaysa heerka soo kabashada.

Is dhexgalka firfircoonayaasha

Sodium sulfide waxay saameyn firfircoon ku leedahay qaar ka mid ah macdanta la xannibay waxaana loo isticmaali karaa marka lagu daro firfircoonayaasha. Tusaale ahaan, kala-soocidda sabbeynta ee macdanta ledhka ee sulfide, galena ay xannibtay cyanide waxaa lagu kicin karaa sodium sulfide ka dibna waxaa lagu soo ururiyaa ethyl thionocarbamate si loo gaaro kala-soocidda naxaasta iyo rasaasta. Isla mar ahaantaana, sodium sulfide waxay sidoo kale saameyn kartaa saameynta firfircoonayaasha kale. Tusaale ahaan, xaddi xad-dhaaf ah oo sodium sulfide ah ayaa laga yaabaa inay isticmaasho ions firfircoon ee saxarka, hoos u dhigista saameynta firfircoonida firfircoonayaasha.

Gabagabadii, fahamka isdhexgalka sodium sulfide iyo reagents kale ee habka sabbeynta ayaa muhiimad weyn u leh hagaajinta habka sabbeynta, hagaajinta heerka soo kabashada iyo darajada macdanta qiimaha leh, iyo dhimista qiimaha macdanta. Injineerada farsamaynta macdanta waxay u baahan yihiin inay si taxadar leh u hagaajiyaan qiyaasta iyo isku xigxiga isku xigxiga ee reagents kala duwan iyadoo loo eegayo sifooyinka gaarka ah ee macdanta si loo gaaro natiijooyinka sabbeynta ugu fiican.
