Nyanzvi Dzinokurukura Basa reSodium Cyanide mukuchera Goridhe

Chekutanga, cyanide sodium gold extraction , inozivikanwawo se cyanide leaching, inzira yagara iripo kwenguva refu. Parizvino, inoda kusvika 30% yegoridhe repasi rose inoburitswa uchishandisa nzira iyi, zvichiratidza kuti inoshandiswa zvakanyanya.

Zvakanakira: Mutengo wakaderera uye unoshanda leaching.

Zvakaipa: Nyaya dzezvakatipoteredza.

Muchokwadi, iyo yechinyakare cyanide dziva leaching process yakagara yakanyorwa kuti ibviswe. Mazuvano, nzira zhinji dzinosanganisira cyanide murwi leaching kana in-situ leaching, asi idzi zvakare dziri kubviswa zvishoma nezvishoma, sezvo parizvino pasina tekinoroji iri nani yekuitsiva.

Sodium cyanide ine muchetura zvakanyanya, saka kutonga kwakasimba uye kutonga kunodiwa pamberi uye mushure mekushandiswa kwayo.

Rega ndipfupise maitiro ekugadzirisa zvicherwa (kana kubatsirwa). Musoro uyu ungaite kunge uri kure kuruzhinji, sezvo vanhu vazhinji vasingazive kuti ore yacherwa, inofanirwa kupfuura nepakati pechicherwa chekugadzirisa zvicherwa. Mukuona kwomunhuwo zvake, simbi inocherwa zvayo yozonyungudutswa musimbi yakananga, handiti? Zvisinei, pfungwa iyi haina kururama zvachose. Maore mazhinji anowanzo akadzikira-giredhi uye ane tsvina yakawanda, zvichiita kuti asakodzere kunyungudika zvakananga. Pamusoro pezvo, kuvapo kwetsvina yakawandisa kunokanganisa nzira yekunyungudutsa, kunowedzera mitengo, uye kunokonzeresa zvigadzirwa zvisina kunaka. Naizvozvo, pane danho rinodikanwa rekugadziriswa kwemaminerari pakati pemigodhi nekunyungudutsa.

Semuenzaniso, kana ukachera simbi ine simbi yemukati (giredhi) ye40%, kuinyungudutsa zvakananga kunogona kutungamirira kune tsvina inokuvadza yakaita sephosphorus, zvichiita kuti simbi inoguma iite brittle. Chii chingaitwa? Iyo ore inogona kugadzirwa kuti iwedzere simbi yemukati kusvika 60% kuburikidza nenzira dzakaita sekuparadzaniswa kwegiravhiti, kupatsanurwa kwemagineti, uye kugaya, zvichikonzera 60% giredhi iron concentrate. Iyi iron concentrate yakave nehuwandu hwehutsvina hwakabviswa uye inogona kushandiswa zvakananga pakunyungudutsa.

Saizvozvo, ores senge lead, zingi, mhangura, molybdenum, uye nickel inodawo kugadzirwa kwemaminerari kuti iomese zvicherwa zvakakosha uye kubvisa tsvina, ichipa zvinhu zvakagadziridzwa zvekunyungudutsa.

Kubva pane tsananguro iri pamusoro, munhu anofanirwa kunzwisisa kukosha kwekugadziriswa kwemamineral. Zvakadini nematombo egoridhe?

Ehe, goridhe ore inodawo mineral processing.

Maore akajairika e lead-zinc anowanzo kuve negiredhi rakabatanidzwa rinosvika 5% kana kupfuura, nemamwe maore emhando yepasi anosvika 2%. Zvisinei, goridhe rakasiyana. Giredhi regoridhe rinoyerwa mumagiramu patani (g/t). Maore mazhinji egoridhe ane magiredhi e1 g/t kana 2 g/t chete, zvichireva kuti kubva patani imwe chete yegoridhe, panogona kunge paine 1 gramu kana 2 gramu yegoridhe. Goridhe iri rinoburitswa sei? Rinowanzoitwa uchishandisa cyanide, iyo inonyungudutsa goridhe kubva muore, uye Carbon inoshandiswa kunyungudutsa nekubvisa goridhe, zvichikonzera tsvina yegoridhe inogona kunatswa kuita zvidimbu zvegoridhe. Maitiro ecyanide parizvino ndiyo nzira inodhura zvakanyanya uye inodhura zvishoma.

Pane here chimwe chinhu chinogona kunyungudutsa goridhe nekutsiva cyanide?

Kutaura zvazviri, kune zvinhu zvakawanda zvinogona kunyungudutsa goridhe, asi kuwana imwe nzira chaiyo inotsiva Sodium cyanide kwakaoma zvikuru.

Thiourea inogona kunyungudutsa goridhe, asi dosi inodiwa yakakura kwazvo, zvichiita kuti idhure!

Polysulfides uye lime sulfur zvinogonawo kushandiswa, asi zvinoda copper ammonia ions, uye dosage yakafanana yakakwirira, zvichiita kuti kudhura kwakanyanya.

Kune zvakare biological leaching nzira, asi idzi dzichiri munhanho yekuyedza.

Dzimwe nzira dzinoshandiswa zvakanyanya ndedzekuburitsa tsvina itsva dzakadai seJINCHAN neJINFU. Kana mishonga iyi ine cyanide, zvinonetsa kuinzwisisa, uye kushanda kwayo zvakanaka inyaya yekukurukurirana. Mimwe migodhi yakatoishandisa zvakanaka, asi kukwidziridzwa kukuru kana tariro yekuti inogona kushandiswa pasi rose seSodium Cyanide kumigodhi mizhinji yegoridhe zvichiri kuoma.

Nokudaro, nzira ye cyanide inoramba iri nzira huru.

Mishonga kana maitiro asina cyanide akagadzirwa nevaongorori mukugadzirisa zvicherwa anotarisana nematambudziko makuru mukusimudzira nekutsigira kubva kumadhipatimendi akakodzera, zvichiita kuti zviome kuishandisa zvakanyanya. Pamusoro pezvose, avo vari muindasitiri vanoziva kuti sodium cyanide inoshanda, iri nyore kushandisa, uye inodhura zvishoma—ndiani asingade kuwedzera purofiti?

Kutsiva maitiro ecyanide, zvakaoma pasina rutsigiro rwakasimba rwenyika rwekusimudzira kana mari yekutsvagisa kwakabatana.

Ichokwadi here kuti nzira dzecyanidation, dziri huru, dzinofanira kukuvadza zvakatipoteredza?

Nyika dzine mitemo yakasiyana-siyana yekudzivirira kwezvakatipoteredza, uye kune nzira dzakasimba dzekurapa uye mirairo yemvura yetsvina yemugodhi, mhinduro dzeleaching, uye masara emarara.

Kutaura zvazviri, sodium cyanide inogona kuva nengozi zvakadini? Ichokwadi kuti kuidya kunogona kuuraya. Zvisinei, inogona kurapwa; nekuwedzera bleaching poda, inogona kuora kuburikidza nekuita redox. Nyika zhinji dzine mitemo, mirau, uye mirau inowirirana kutonga nyaya iyi.

Kuti uwane mamwe mazano ehunyanzvi? Taura nesu!

Mazano Anodziya: Kana iwe uchida kuziva rumwe ruzivo, senge quotation, zvigadzirwa, mhinduro, nezvimwe,
