Nyanzvi Dzinokurukura Basa reSodium Cyanide mukuchera Goridhe

Chekutanga, cyanide sodium goridhe kutorwa, inozivikanwawo se cyanide leaching, inzira yakagara yakadzikwa. Parizvino, chikamu chinosvika makumi matatu kubva muzana chegoridhe repasi rose rinocherwa pachishandiswa nzira iyi, zvichiratidza kushandiswa kwaro kwakapararira.

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 egoridhe akajairika anowanzo kuve negiredhi rakabatanidzwa re5% kana kupfuura, nemamwe maore epamusoro-soro ari pa2%. Zvisinei, goridhe rakasiyana. Giredhi regoridhe rinoyerwa mumagiramu patani (g/t). Maore egoridhe mazhinji ane magiredhi e1 g/t chete kana 2 g/t, 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, yozoshanda. kabhoni inoshandiswa kunyudza nekubvisa goridhe, zvichikonzera tsvina yegoridhe inogona kunatswa kuita zvidimbu zvegoridhe. Maitiro ecyanide parizvino ndiyo nzira inodhura zvakanyanya uye isingadhuri.

Pane here chimwe chinhu chinogona kunyungudutsa goridhe nekutsiva cyanide?

Muchokwadi, kune zvinhu zvakawanda zvinogona kunyungudutsa goridhe, asi kutsvaga imwe yechokwadi imwe nzira Sodium cyanide zvakaoma.

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.

Idzo dzinonyanyo shandiswa dzimwe nzira ndedzipi itsva leaching agents seJINCHAN neJINFU. Kana vamiririri ava vane cyanide zvinogoneka, uye kushanda kwavo inyaya yekukurukurirana. Mimwe migodhi yakatoishandisa nemhedzisiro yakanaka, asi kukwidziridzwa kwakakura kana tariro yekuti inogona kushandiswa pasi rose se Sodium Cyanide nokuti migodhi mizhinji yegoridhe ichiri yakaoma.

Nokudaro, nzira ye cyanide inoramba iri nzira huru.

Iyo cyanide-isina leaching agents kana maitiro akagadzirwa nevatsvaguri mukugadzirisa zvicherwa anotarisana nematambudziko makuru mukusimudzira nerutsigiro kubva kumadhipatimendi akakodzera, zvichiita kuti zviome kuita zvakanyanya. Mushure mezvose, avo vari muindasitiri vanozviziva sodium cyanide inoshanda, iri nyore kushandisa, uye inodhura-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,
