Ukuzuza igolide

Imithombo yegolide eRefractory ingahlulwa ngokubanzi ibe ziindidi ezintathu eziphambili:
Uhlobo lokuqala luphezulu lwe-arsenic, ikhabhoni, kunye ne-ore yegolide yohlobo lwesulfure.Kulo hlobo, umxholo we-arsenic ungaphezulu kwe-3%, umxholo wekhabhoni ngu-1-2%, kwaye umxholo wesulfure ngu-5-6%.Ukusebenzisa inkqubo yesiqhelo yokukhutshwa kwegolide ye-cyanide, izinga legolide le-leaching liyi-20-50% ngokubanzi, kwaye ixabiso elikhulu le-Na2CN lidliwe.Xa utyetyiswe bubugcisa bokudada, nangona umgangatho ophezulu wegolide unokufumaneka, ugxininiso luqulethe amanqanaba aphezulu ezinto eziyingozi ezifana ne-arsenic, i-carbon, kunye ne-antimony.Kuya kuba nefuthe kwisinyathelo esilandelayo senkqubo yokukhutshwa kwegolide.

Uhlobo lwesibini luyi-ores enegolide apho igolide ifakwe kwi-ganggue minerals kunye nokungcola okuyingozi kwiincinci ezincinci kunye neefom ze-microscopic.Kulo hlobo, i-metal sulfide incinci, malunga ne-1-2%, kwaye ifakwe kwi-ganggue minerals.Iincinci zegolide ezicokisekileyo kwiikristale zibalelwa kwi-20-30%.Iindlela eziqhelekileyo zokutsalwa kwe-cyanide okanye iindlela zokutyebisa ezidadayo zisetyenziselwa ukukhupha igolide, kodwa izinga lokubuyisela igolide liphantsi kakhulu.

Uhlobo lwesithathu yintsimbi yegolide enobudlelwane obusondeleyo phakathi kwegolide, i-arsenic kunye nesalfure.Uphawu lwayo kukuba i-arsenic kunye nesulfure yizona zimbiwa eziphambili zegolide, kwaye umxholo we-arsenic uphakathi.Isalathisi segolide solu hlobo lwentsimbi ekrwada kusetyenziswa inkqubo enye yokutsalwa kwegolide yecyanide sisezantsi noko.Ukuba igolide ityetyiswe yi-flotation, izinga eliphezulu lokubuyisela linokufumaneka, kodwa kunzima ukuthengisa kuba iqulethe i-arsenic eninzi.

iteknoloji yezemigodi

Ukukhetha imichiza

1. Ukuchithwa kwegolide kunye nokwahlula

Iindlela zokuzuza imichiza kwimigodi yegolide ikakhulu zibandakanya indlela yamanzi ashushu kunye nendlela yecyanide.Indlela exubileyo indala kwaye ifanelekile kwigolide enye ene-coarse-grained.Noko ke, ngokwentelekiso iyangcolisa yaye ngokuthe ngcembe iye yathatyathelw’ indawo bubulumko.Kukho iindlela ezimbini ze-cyanidation, ukuvuselela i-cyanidation kunye ne-percolation cyanidation.

2. Izixhobo zokukhetha iikhemikhali kunye negolide

Indlela yemichiza isetyenziswa ekukhetheni intsimbi ekrwada yegolide, ingakumbi indlela yeatmosfera.Isixhobo esisetyenziswayo sibandakanya isixhobo sokutshintshiselana ngomgubo we-zinc, itanki yokuvuza, njl. njl. Isixhobo sokutshintsha umgubo we-zinc sisixhobo esithatha indawo yodaka lwegolide kwilehayithi ngomgubo we-zinc.

I-tank yokuvuselela i-leaching sisixhobo sokuvuselela i-slurry.Xa ubukhulu be-ore particle bungaphantsi kwe-200 mesh kunye noxinzelelo lwesisombululo lungaphantsi kwe-45%, ukumiswa kunokuqulunqwa ukunyusa i-concentration yegolide enyibilikisiweyo kwi-tank ye-adsorption kunye nokukhawulezisa ixesha le-leaching.
