Zvinhu Zvinoverengeka Zvaunofanira Kuziva NezveGoridhe Cyanidation

Gold cyanidation inzira yekuchera goridhe uchishandisa cyanide semumiririri weLeaching. Nekuda kwehukuru hwayo hwehunyanzvi nhanho, chiyero chakakwira, uye kushanda kwakasimba kune ores, nzira yecyanidation inoramba iri imwe yenzira huru dzekuchera goridhe parizvino. Mu Gold cyanidation maitiro, nhanho imwe neimwe inofanirwa kudzorwa kuti ive nechokwadi chezvakanaka zvehupfumi uku uchidzikisa huremu hwemidziyo uye kudyara.

1. Aeration uye Cyanide Addition

Mushure mekugaya, cyanide inowedzerwa kune pulp kuti iparadze goridhe uye igadzire simbi yakaoma. Maitiro ekuita ndeaya anotevera: 4Au + 8NaCN + O2 + 2H2O → 4NaAu(CN)2 + 4NaOH. Sezvinoonekwa kubva pane iri pamusoro fomula, okisijeni inodiwa mukuita leaching goridhe. Naizvozvo, mukugadzirwa kwemaindasitiri, tangi rekudonha rinoda kufefeterwa. Iyo aeration pressure inowanzoita 1 kg, uye iyo aeration vhoriyamu paminiti yega yega cubic mita yeslurry yakakura kupfuura 0.002 m³.

2. Kuwedzera Protective Alkali

Kuve nechokwadi chekusangana kwe cyanide mu pulp, kudzivirira kusvibiswa kwezvakatipoteredza, uye kudzivirira kugadzirwa kwechepfu hydrogen cyanide (HCN) gasi, alkali inofanirwa kuwedzerwa kune leaching tank kuchengetedza yakakwira pH kukosha kwepulp. Lime kana lime mukaka unowanzoshandiswa mukugadzirwa kwemaindasitiri, uye dzimwe nguva NaOH inowedzerwa kuti igadziriswe.

3. Kuchengeta Slurry Kumiswa

Iyo goridhe cyanidation process ine zvimwe zvinodiwa pakuita kweleaching agitation tank. Nekushandisa kwakaderera kwesimba, zvimedu zvemonomer-yakaparadzaniswa kana yakafumurwa pamusoro pegoridhe mupulp haifanirwe kuisa mutangi. Iyo pulp, cyanide, lime, uye mweya zvinofanirwa kusanganiswa zvizere mutangi kuti isvike payakamiswa. Iyo slurry concentration muchikamu chega chega chetangi inofanirwa kuenderana, uye hapafanirwe kuve nestratification pamwe nekwakadzika gwara retangi, uye kugoverwa kwesaizi kunofanirwa kuve kwakafanana.

4. Kuchengeta Yakakodzera Slurry Concentration

Kana iyo density yegoridhe ore iri 2.65 - 2.8. iyo general leaching pulp concentration ndeye 40 - 45%. Kana iyo density ye flotation concentrate iri 3 - 3.5. iyo general leaching concentration ndeye 30 - 40%. Kazhinji, zvinhu zvine fineness isingasviki 200 mesh account ye80 - 95%.

5. Kuderedza Kupfeka uye Noise yeZvikamu Zvinofamba

Kuti uderedze kupfekwa kweagitator uye kuwedzera hupenyu hwayo hwesevhisi, akawanda mapellers mukugadzirwa kwemaindasitiri ane rubber-lined. Kusarudzwa kwemudziyo wekutapurirana kunofanirwa kuve nehungwaru kuti ive nechokwadi chepamusoro chekufambisa uye ruzha rwakadzika.

6. Kuderedza Carbon Wear

The kabhoniNzira ye -in-pulp inowedzera kabhoni mutangi re adsorption kuti inyudze goridhe. Kana simba re agitation retangi re leaching rakasimba zvakanyanya, kabhoni ichakuyiwa yorasika. Kana simba re agitation risina simba, sediment ichagadzirwa. Saka, paunenge uchichengetedza pulp iri mumamiriro ekumira, kune rumwe rutivi, zvakakosha kusarudza kabhoni yakasimba kuti ishandiswe, uye kune rumwe rutivi, zvakakosha kuderedza kumhanya kwekutenderera kwe impeller kuderedza kurasikirwa kwe pulp, kabhoni, uye simba rekupinda retangi re agitation adsorption.

7. Kusarudza Kugona Kwakakodzera

Parizvino, kugona kugadzirisa kwezvakajairwa goridhe cyanidation zvidyarwa kubva pamakumi akati wandei ematani kusvika makumi ezviuru zvematani pazuva. Kukura kwesimba rekugadzira, hombe nzvimbo yechirimwa, uye yakakura iyo michina yakatarwa uye mari. Muridzi wega wega wemugodhi anofanirwa kuona yakakodzera kugadzirisa chirimwa zvinoenderana nemamiriro chaiwo.

8. Kuderedza Equipment Weight uye Investment

Paunenge uchisarudza tangi yeleaching, kune rumwe rutivi, iyo leaching process inodiwa kuti ishande uye ichengetedze simba, uye panguva imwecheteyo, mudziyo wekutapurirana unodiwa kuve nediki tsoka uye huremu huremu. Kana huwandu, kusungirirwa kwe pulp, uye nguva yekuregedza yakatemwa, huwandu hwematangi ekudonha hunogona kutariswa. Nekudaro, izvo zvinongedzo zvematangi ekudonha anofanirwa kuve akakodzera kusimba rechirimwa. Paunenge uchivaka 500t / d goridhe cyanidation chirimwa, kana φ3.5X3.5m leaching tank ikashandiswa, iyo inodiwa michina inoda kuwedzerwa, kuwedzera mari. Naizvozvo, chete nemidziyo yakareruka uye nehunyanzvi hwakakodzera hunogona kuderedzwa kwekudyara kwekuvaka kwebhizinesi.
