"Ilaaliyaha" Birta Qiimaha Badan: Sababta Dithiophosphates (Agents Madow) loogu Isticmaalo Macdanta

Dhirta sabbeynta, xanthates waxaa si weyn loogu aqoonsadaa inay yihiin ururiyayaal awood leh oo leh awood ururin guud oo xooggan. Si kastaba ha ahaatee, si loo hagaajiyo soo kabashada dahabka iyo lacagta ama kala soocida rasaasta zinc, khubarada birta ee khibradda leh waxay inta badan ku taliyaan dithiophosphates, oo loo yaqaan "wakiillo madow" sababtoo ah muuqaalkooda dareeraha madow, oo badanaa muuqda. Iyadoo ay jiraan muuqaalkooda aan la yaabin, walxahan firfircoon waxay bixiyaan faa'iidooyin kala duwan oo lagu daweeyo biraha qaaliga ah iyo macdanta sulfide ee adag.

I. Waa maxay Dithiophosphates (Madow Wakiilo)?

Dithiophosphates waa nooc ka mid ah ururiyayaal kiimiko ahaan la xiriira xanthates. In kasta oo xanthates ay yihiin ururiyayaal xooggan, oo aan xulasho lahayn oo u janjeera inay sabeeyaan sulfide bir ah (pyrite), dithiophosphates waa kuwo aad u xulasho badan. Sidoo kale waa kuwo kiimiko ahaan deggan oo aan u nugul inay kala daato.

II. Faa'iidooyinka Muhiimka ah

1. Xidhiidh Hoose oo u dhexeeya Pyrite: Tani waa faa'iido weyn oo lagu kala saaro sunta rasaasta ama naxaasta ah ee pyrite. Xanthates waxay u muuqdaan inay sabeeyaan pyrite sidoo kale, halka dithiophosphates ay muujiyaan awood ururin oo daciif ah oo ku wajahan pyrite, taasoo sahlaysa kala-soocidda.
2. Awood Ururin Xoog leh oo loogu talagalay Dahabka iyo Lacagta: Dithiophosphates waxay sameeyaan isku xidhka kiimikada ee deggan oo leh dusha sare ee birta qaaliga ah, taasoo ka dhigaysa kuwo aad waxtar ugu leh soo celinta dahabka, lacagta, iyo platinum. Warshad badan oo dahab ah ayaa ku dara dithiophosphates (tusaale ahaan, Aero 238 ama ammonium dibutyl dithiophosphate) wareegyada qashinka ama nadiifka ah si loo kordhiyo soo kabashada birta qaaliga ah.
3. Sifooyinka Burburka: Dithiophosphates badan (tusaale ahaan, Aero 238) waxay leeyihiin awood xumbo abuur oo dabiici ah, taasoo yareyneysa ama baabi'ineysa baahida loo qabo xumbo dheeraad ah (sida MIBC ama saliidda geedka). Burburka la soo saaro wuxuu u muuqdaa inuu jilicsan yahay oo si fudud ayuu u burburaa.

III. Noocyada Caadiga ah

• Aero 238 (Alkyl Dithiophosphate): Nooc dareere caadi ah oo leh sifooyin ururin iyo xumbo. Ku habboon kala soocidda rasaasta iyo zinc-ka iyo soo kabashada naxaasta iyo dahabka. Waxay leedahay ur xooggan iyo sifooyin daxal leh.
• Ammonium Dibutyl Dithiophosphate: Waxaa loo heli karaa budo cad (inkastoo magaca "madow" uu yahay). Ma aha mid daxal leh, ur yar, biyo-milma. Ku habboon macdanta lacagta leh iyo macdanta naxaasta ee aan la qabsan karin, gaar ahaan meelaha ay khuseyso deegaanka.
• Diphenyl Dithiophosphate: Wax yar ayay ka yar tahay, awood u leh ururinta xooggan. Waxaa loo isticmaalaa galena-da oksaydhaysan ama kuwa jilicsan.

IV. Tixgelinta Hawlgallada

• Khatarta Daxalka: Dithiophosphates-ka dareeraha ah (tusaale ahaan, Aero 238) waa aashito iyo miridh. Isticmaal agab u adkaysta aashitada si aad u hesho khadadka qiyaasta. Hawlwadeennada waa inay xirtaan qalabka ilaalinta shaqsiga ee ku habboon.
• Iska ilaali inaad qaadato xad-dhaaf: Qiyaasta xad-dhaafka ah waxay keeni kartaa xumbo xad-dhaaf ah, taasoo keenta inay ka buuxsanto (“qaado”) unugyada sabeynaya. Si taxaddar leh u hagaaji qiyaasta, gaar ahaan marka sidoo kale la isticmaalayo xumbo.
• Kinetics Gaabis ah: Dithiophosphates waxay u dhaqmaan si ka gaabis ah marka loo eego xanthates waxayna badanaa u baahan yihiin waqti dheeri ah oo lagu qaboojiyo si loo helo waxqabad wanaagsan.

V. Gunaanad

Dhaqanka casriga ah ee sabeynta, dithiophosphates ma aha beddel xanthates laakiin waa reagents-ka is-waafajiya. Istaraatiijiyad caadi ah ayaa ah in la isticmaalo xanthates si loo soo kabto bulkka marka la sabbaynayo iyo dithiophosphates si loo helo marxalado nadiif ah si loo xoojiyo xulashada loona soo celiyo biraha qaaliga ah.
