[Flotation Agent-Collector Service] Imiterere na Porogaramu ya Xanthate

Gukusanya umukozi ni umukozi wa flotation ahindura hydrophobicioty yubutare hejuru kandi ituma uduce tureremba twuzuyemo amabuye y'agaciro akurikiza ibituba. Icyiciro cyingenzi cyane kugirango uhitemo ni ibiryo. Ifite imitungo ibiri yibanze: (1) irashobora guhitamo hejuru yubutare; . Xanthate numwe mubatoza bakomeye!

Umutungo wa Xanthate:
Xanthate ni Xanthate, izina rya siyansi ni Hydrocarbyl Dithiocarbonate. Irashobora gufatwa nkibicuruzwa bya karubone aho icyuma kion gisimburwa nitsinda rya hydrocarbylbylby na atome ebyiri zasimbuwe na atome ya sulfuru. Muri rusange, formula ni r-ocssme, nka sodium ethyl xanthate. R Muri rusange akenshi ni Hydrocarbon ya Adiphatic Itsinda CNH2N + 1, aho n = 1 ~ 6, kandi gake nitsinda rya hydrocarbon, itsinda rya mugitondo, nibindi (+), k (+), k (+), k (+), k (+), k (+), k (+), k (+), k (+), k (+), k (+ ), nibicuruzwa byinganda akenshi na (+). Imitungo ya Kaxanthate na sodium xanthate kimwe, ariko kaxanate irahagaze neza kuruta sodium xanthate, mugihe kaxanhate ntabwo iri byoroshye kurenza iyo ya sodium xanthate. Byose byoroshye gushonga mumazi, inzoga na acetone.

Mubisanzwe, methyl xanthate na ethyl xanthate bitwa umwanya muto wa xanthate, hamwe nabafite inanga kandi hejuru yitwa xanthate. Xanthate ni kristalline cyangwa ifu. Umwanda usanga akenshi wumuhondo-icyatsi cyangwa orange-umutuku gelatinous hamwe nubucucike bwa 1.3 ~ 1.7 g / cm3. Ifite impumuro nziza kandi ifite uburozi (hagati). Umunyururu muto-xanthateroshye byoroshye mumazi, gushonga muri acetone n'inzoga, kandi byoroshye muri ether na pether ether. Kubwibyo, acetone-ether-ether ivanze uburyo bwo gukemura burashobora gukoreshwa mugusubiza no kweza xanthate.

Gusaba no kubika xanthate
Ubushobozi bwo gukusanya no guhitamo xanthate kumabuye y'agaciro atandukanye afitanye isano rya bugufi nibicuruzwa byonyine byicyuma cya xanthate. Amabuye y'agaciro isanzwe akunze kugabanywamo ibice bitatu bishingiye kubicuruzwa byonyine byicyuma Xanthate: (1) Ibicuruzwa bya chalcophilic eth xanthate biri munsi ya 4.9 × 10 ^ -9. Ibyuma bigwa muri iki cyiciro birimo AU, AG, HG, CB, PB, CD, CD, ETC Amabuye y'agaciro y'ibisanzwe by'ibyo bintu. . Ibyuma bigwa muri iki cyiciro birimo ZN, Fe, MN, nibindi Xanthate ifite ubushobozi runaka bwo gukusanya amabuye y'agaciro yo gukusanya amabuye y'agaciro y'ibintu, ariko biracika intege. Niba Xanthate ikoreshwa nkukusasu, biroroshye kugera ku gutandukanya flotation ibyuma bya sulfide ibyuma bisenyuka nibikoresho bya chalcophile hamwe na sinema ya sulcopral ari ibintu bya sitrophile. Nubwo ibicuruzwa byo gukurura Ethyl Xanthate bya Cobalt na Nikel bari munsi ya 10 ^ -1 kandi ni ibintu bigize ibikombe, akenshi symbiose hamwe na symiose ya fernide hamwe na blabel ya sulfide. . Ibyuma biri muri iki cyiciro birimo CA, MG, Ba, nibindi bikabije byibicuruzwa byayo byicyuma. Gukusanya ingaruka kuri ubu bwoko bwimicure yicyuma. Kubwibyo, Xanthate ntabwo ikoreshwa nkumukusanya mugihe utondekanya icyuma cya alkali na alkaline isi yubucukuzi bwibimamara, amavuta ya salle. Mubisanzwe, ibicuruzwa byonyine byibyuma bya sulfide ni bito kurenza umusaruro wonyine wicyuma gihuye na ethyl Xanthate. Ukurikije amahame mvurumico, ntibishoboka kuri xanthate anion x (-) kwitwara nubuso bwamabuye y'agaciro no gusimbuza s (2-). Gusa iyo ubuso bwibyuma bya sulfide ya okiside isa, s (2-) hejuru yibyuma bya sulfide isimburwa na Oh (-), Sooni (2-) ;, So3 ( 2-), na nyuma ya plasma, icyuma mugihe ibicuruzwa byo gusambo bya xanthate ari bito kuruta ibicuruzwa byicyuma bihuye, birashoboka kuri xanthate anion X (-) gusimbuza anion bihuye na oxide yicyuma hejuru yicyuma cya sulfide. Xanthate ikunze gukoreshwa nkukusanya amashanyarazi (nka au, ag, cu, nibindi, nibindi) na sinema ya sulcopral muri chalcophile hamwe nibintu bya sinema. Kugirango wirinde hydrolysis, kubora no kunyeganyega gukabije kwa xanthate, xanthate bigomba kubikwa mubikoresho byiza. Irinde guhura numwuka ushushe hamwe namazi, witondere amazi meza kandi yubushuhe, kandi ntugomba guhura nizuba cyangwa ngo ubitswe igihe kirekire. Igomba kubikwa ahantu hakonje kandi byumye kandi bihumeka. Igisubizo cya Xanthate giteganijwe kitagomba gusigara igihe kirekire, kandi amazi ashyushye ntagomba gukoreshwa mugutegura igisubizo cya xanthate. Igisubizo cya Xanthate gikoreshwa muri rusange kikoreshwa muburyo buhumanye, kandi kwibanda kubitegura Xanthate kugirango umusaruro ni 5%.
