Gold Beneficiation

Refractory goridhe zviwanikwa zvinogona kupatsanurwa mumhando nhatu huru:
Mhando yekutanga ndeyepamusoro arsenic, carbon, uye sulfur mhando yegoridhe ore.Mumhando iyi, iyo arsenic inodarika 3%, iyo kabhoni inokwana 1-2%, uye sarufa inokwana 5-6%.Uchishandisa yakajairwa cyanide goridhe kudhirowa maitiro, iyo goridhe leaching rate Inowanzo 20-50%, uye yakawanda yeNa2CN inopedzwa.Kana yakapfumiswa nehunyanzvi hwekufambisa, kunyangwe giredhi repamusoro regoridhe rinogona kuwanikwa, concentrate yacho ine huwandu hwakawanda hwezvinhu zvinokuvadza zvakaita searsenic, kabhoni, uye antimony.Ichava nemigumisiro padanho rinotevera rekuchera goridhe.

Rudzi rwechipiri iora rine goridhe umo goridhe rinoputirwa mumaminerari e gangue uye tsvina inokuvadza muzvikamu zvakatsetseka uye zvimiro zvisingaonekwi.Mumhando iyi, iyo simbi sulfide yemukati idiki, inenge 1-2%, uye yakaiswa mumaminerari e gangue.Zvimedu zvegoridhe zvakanakisa mumakristasi anoita 20-30%.Dzakajairwa cyanide kudhirowa kana flotation hupfumi nzira dzinoshandiswa kuburitsa goridhe, asi goridhe rekudzoreredza mwero wakaderera zvakanyanya.

Rudzi rwechitatu isimbi yegoridhe ine hukama hwepedyo pakati pegoridhe, arsenic nesarufa.Chimiro chayo ndechekuti arsenic nesarufa ndiyo inotakura zvicherwa zvegoridhe, uye iyo arsenic yemukati ndeyepakati.Iyo goridhe leaching index yerudzi urwu rweore uchishandisa imwe chete cyanide goridhe kuburitsa maitiro yakadzikira.Kana goridhe rakafumiswa nekutenderera, chiyero chepamusoro chekudzorera chinogona kuwanikwa, asi chakaoma kutengesa nekuti ine arsenic yakawandisa.

tekinoroji yemigodhi

kusarudzwa kwemakemikari

1. Gold mineralization uye kupatsanurwa

Nzira dzekubatsira makemikari emigodhi yegoridhe dzinonyanya kusanganisira nzira yemvura inodziya uye nzira yecyanide.Iyo yakasanganiswa nzira ndeyekare uye yakakodzera kune coarse-grained imwe goridhe.Zvisinei, hunoshatisa uye hwakatsiviwa zvishoma nezvishoma nouchenjeri.Kune nzira mbiri dzecyanidation, inokurudzira cyanidation uye percolation cyanidation.

2. Michina yekusarudza kemikari negoridhe

Nzira yemakemikari inoshandiswa kusarudza ore yegoridhe, kunyanya nzira yemhepo.Midziyo inoshandiswa inosanganisira zinc powder exchange device, leaching stirring tank, etc. Zinc poda yekutsiva mudziyo mudziyo unotsiva dhaka regoridhe kubva muleachate nehupfu hwezingi.

The leaching stirring tank mudziyo wekukuchidzira slurry.Kana iyo ore particle size iri pasi pe200 mesh uye mhinduro yekumisikidza iri pasi pe45%, kumiswa kunogona kugadzirwa kuti kuwedzere kuwanda kwegoridhe rakanyungudutswa mutangi readsorption uye nekumhanyisa nguva yekudonha.
