Ndeipi michina yekuchera goridhe?

Nzira yekubvisa goridhe kubva kumabhodhi edunhu?

Midziyo yakabatanidzwa yekuburitsa goridhe: michina yakakura yekuputira goridhe nesirivha, kabhineti yekufema, muchina wekudira mvura, ketero yegirazi, mota yekusefa yeaqua regia, system yePh otomatiki yekuyedza, muchina wakabatanidzwa wekuderedza nekusefa, barrel yekusefa yegoridhe yesponge, tangi rePP reduction reaction, tangi rekusagadzikana, ketero yekaviri yemhinduro yegoridhe rakanyungudutswa, michina yekurapa gasi rakasviba, nezvimwewo.

Mutengo wemidziyo yekuchenesa goridhe yemabhodhi edunhu wakakura zvikuru, kubva pamakumi ezviuru kusvika kumazana ezviuru. Mutengo wacho unokonzerwa nezvinhu zvakaita sehukuru hwemuchina, zvinhu zvekugadzira, mhando, dhizaini yemaitiro, uye saizi yekubuda, uye zvinogona kuchinja-chinja zvichikwira nekudzika. Zvakaoma kuona mutengo wakatarwa, uye vagadziri vanogona kungopa mutengo chaiwo mushure mekuona zvaunoda nemamiriro chaiwo ekushanda.

Midziyo yekuchenesa simbi inokosha inonyanya kushandiswa kuburitsa simbi dzinokosha dzakadai segoridhe, sirivha, platinum, palladium, nezvimwewo. Parizvino, Fuxin Environmental Refining inonyanya kushandisa nzira dzakadai sekuchenesa chlorination, kuchenesa aqua regia, kuchenesa electrolysis, kuchenesa chloramine, nezvimwewo.

Midziyo inowanzoshandiswa inosanganisira: michina mikuru yekuisa electroplating yakakwana/muchina wegoridhe nesirivha wekudzoreredza magetsi, kabhineti yekufema, muchina wekuisa mvura, ketero yegirazi, mota yefirita yeaqua regia, system yekuisa dosing otomatiki yePh, muchina wekuderedza nekusefa, barrel yefirita yesponge gold, tangi rekuderedza reaction yePP, tangi rekusagadzikana, ketero yemhinduro ine layer mbiri yekunyungudutsa goridhe, uye michina yekurapa gasi rakasviba.

Ndedzipi nzira dzekubvisa simbi dzinokosha kubva mugoridhe?

Ndarama chigadzirwa chechisikigo chisingagone kugadzirwa, uye chakakamurwa kuita goridhe risina kugadzirwa uye goridhe rakabikwa. Ndarama yakasvika pakuchena kwakanyanya mushure mekucheneswa inonzi goridhe rakachena, kazhinji zvichireva goridhe rine hunyoro hwepamusoro pe99.6%. Ndarama yakacheneswa inowanzova yakachena kwazvo, uye imwe inogona kushandiswa zvakananga mukugadzira maindasitiri.

1. Maitiro Ekuchenesa Goridhe

Kuyerera kamwe chete kwakakodzera kugadzirisa simbi yegoridhe yechisikigo yakaoma uye yepakati. Mhangura yakapwanywa inoiswa mubhora, yoitwa slurry, yozopinda muflotation. Kuyerera kwemercury kwakasanganiswa kwakakodzera kugadzirisa goridhe rechisikigo rine saizi yezvidimbu zvakakasharara, zvakachengetwa mupyrite nedzimwe sulfide ores. Kusiyana nekuyerera kamwe chete, kuwedzera plate yemercury mushure mekukuya kuti goridhe ridzorerwe kunogona kuwana chiyero chekudzoreredza che30-45%. Belt conveyor muyadhi yemashure; Jecha resimbi risina kukura kupfuura buri rekusefa rinoiswa mumuchina we circular jigging we 1-3 stage kuburikidza nemuchina we public mixer, uye concentrate inoyerera mutafura inozunguzika kuburikidza nemuchina we 3-stage jigging kuti igadzire simbi yakanaka, yakanaka, uye yakatsvaira kuti igadzire simbi yakanaka. Nzira iyi inowanzoshandiswa kumigodhi yejecha rinokasharara, uye simbi dzakapwanyika dzakakasharara dzinogonawo kushandiswa.

2. Nhanganyaya yeNzira yeKubvisa Goridhe neKusanganisa Mercury neGoridhe Kucheneswa

Iyi inzira yekare yekuchenesa goridhe, chero bedzi uine mwoyo murefu, unogona kutaura nezve kuchena kwakanyanya. Nzira dzacho ndeidzi dzinotevera:

Goridhe+mercury+mvura, zvichigaya nguva dzose kusvika pasisina zvidimbu zvegoridhe, uye goridhe nemercury zvinoumba makemikari epakati pemetallic. Gaya uye sanganisa hupfu hwesarufa negoridhe rakasanganiswa nemercury, woipisa woipisa mumhepo. Panguva ino, mercury yasara inopwanyika, uye simbi dzepasi dzinotanga dzagadzira simbi sulfides, iyo inozogadzira simbi oxides. Dzokorora mashandiro ari pamusoro apa kakawanda uye wedzera borax kuti inyunguduke kuita ingots dzegoridhe. Base metal oxides dzinoita neborax kuti dzigadzire zvinhu zvishoma zvinonyunguduka, izvo zvinoyangarara pamusoro pemvura. Pure gold ichashandisa nzira iyi iri pasi kudzivirira chepfu ye mercury vapor.

3. Nhanganyaya yeMaitiro ekuchenesa Goridhe Rakanyorova pakubvisa Goridhe

Maitiro ekuchenesa goridhe rakanyorova anoshandisa nzira yekunyungudutsa goridhe mu aqua regia uye kuwedzera chinodzikisa goridhe kuti rideredze goridhe, kana kana chinovhara goridhe chikashandiswa kusanganisa zvinhu zvakaoma, zvichiteverwa nekubviswa nechinhu chekutanga kana chinoburitsa. Ichi chigadzirwa chinoputsa maitiro echinyakare akadai sekunyungudutsa kupisa kwakanyanya uye mamwe maitiro ari nyore ekuchenesa kuti uwane goridhe remhando yepamusoro. Zvichienzaniswa netekinoroji dziripo, chigadzirwa ichi chine hunhu hwekuchena kwechigadzirwa, mitengo shoma yekugadzira, uye maitiro ari nyore uye anoshanda. Imwe nzira ndeyekuchenesa goridhe rakanyorova, iro rinosanganisira kuisa goridhe rakanyorova mumudziyo, kuriisa mu aqua regia ichangogadzirwa kuti inyudze goridhe rakanyorova, uye wozoripisa kuti rinyungudike kwemaminitsi 15-25. Kana goridhe rakanyorova risina kunyungudika zvachose, aqua regia inogona kuwedzerwa kuti inyungudike kakawanda kusvika yanyungudika zvachose.

Chekupedzisira, shandisai michina yekukanda simbi inokosha yeHasung kugadzira simbi dzegoridhe dzinopenya, imuchina wekugadzira granulating muchina wekukanda bhaa regoridhe muchina wekunyungudutsa we induction , nezvimwewo.
