Ruzivo rwakajairwa nezve cyanide sodium kutorwa kwegoridhe yaungasaziva

Munyika yekuchera goridhe, nzira yekubvisa Cyanide inzira yakakosha inoshandiswa kudzosa goridhe kubva mumatombo. Kunyange hazvo vazhinji vachiziva izwi rekuti "cyanide," kuomarara kwekushandiswa kwayo mukubvisa goridhe kunowanzo furatirwa. Chinyorwa chino chine chinangwa chekujekesa ruzivo rwakawanda pamusoro peSodium cyanide nebasa rayo mukubvisa goridhe , zvichiita kuti pave nekunzwisisa kwakazara kwenzira iyi inokosha.

Iyo Cyanide Gold Extraction process

Maitiro ekubvisa goridhe recyanide anosanganisira matanho akati wandei akakosha, rimwe nerimwe richida kudzorwa kwakanyatsojeka kwezvikamu zvakasiyana-siyana kuti zvive nechokwadi chekuti mhedzisiro yakanaka. Zvinhu zvikuru zvinofanirwa kutariswa zvinosanganisira kuwanda kwecyanide, kuwanda kweokisijeni, alkalinity, uye nguva inodiwa kuti inyunguduke. Zvinhu izvi zvakakosha kuti uwane mhando inodiwa yekudzoreredza goridhe.

1. Kubvisa goridhe: Danho rekutanga mukuita uku kubvisa goridhe, uko goridhe rakasimba rinonyungudutswa mu oxygen-containing cyanide solution. Iyi solution inobvumira kuburitswa kwegoridhe kubva mu mineral, zvichiita kuti rikwanise kuparadzaniswa nemamwe mamineral.

2. Kusuka: Mushure mekubviswa kwegoridhe, danho rinotevera kusukwa. Maitiro aya anosanganisira kudzosa mvura ine goridhe mushure mekubviswa kwegoridhe uye kusukwa goridhe rakanyunguduka kubva pamusoro pezvidimbu zvematombo. Chinangwa ndechekuparadzanisa goridhe nemvura yakasimba, kuve nechokwadi chekuti goridhe rabviswa kubva pane zvasara.

3. Kutsiva: Danho rekupedzisira mukubvisa goridhe nderekutsiva, uko mvura ine goridhe inogadziriswa nesimbi inonzi metallic zinc. Danho iri rinoderedza uye rinoita kuti goridhe rirambe rakasimba, zvichiita kuti ridzoke rakasimba.

Key Compounds muCyanide Gold Extraction

Makomisheni maviri ekutanga anoita basa rakakosha mucyanide goridhe kudhirowa maitiro: cyanide uye inodzivirira alkali.

1.Cyanide

Cyanide ndiyo musimboti wekubvisa tsvina. Mumaindasitiri, mhando dzakasiyana dzecyanide dzinoshandiswa, dzinosanganisira Potassium cyanide (KCN), sodium cyanide (NaCN), Calcium cyanide [Ca(CN)2], uye Ammonium cyanide (NH4CN). Pakati peizvi, sodium cyanide ndiyo inonyanya kushandiswa nekuda kwekushanda kwayo uye kuwanikwa kwayo.

Sodium cyanide ihupfu chena ine muchetura unowanzo gadzirwa mune spherical kana block mafomu kuitira nyore kubata. Simba rayo semumiririri weLeaching inoita kuti ive yakakosha mukuita kwekubvisa goridhe, asi inodawo maprotocol akasimba ekuchengetedza kudzikamisa njodzi dzine chekuita nehupfu hwayo.

2. Dziviriro Alkali

Basa rekuchengetedza alkali mune yecyanide goridhe kuburitsa maitiro haigone kuderedzwa. Chinangwa chikuru chekuwedzera alkali inodzivirira ndeyekuchengetedza kugadzikana kweiyo cyanide mhinduro uye kuderedza kurasikirwa kwecyanide kuburikidza nehydrolysis. Izvi zvinonyanya kukosha mukuona kuti nzira yekudzidzira inoramba ichishanda uye inoshanda.

Chengetedza alkali inowanzowedzerwa panguva yechikamu cheleaching kana panguva yekukuya cyanide ore. Mumamiriro ezvinhu apo kuumbwa kwe ore kwakaoma uye kune zvicherwa zvakadai se pyrrhotite, izvo zvinogona kukanganisa maitiro e cyanide, kuwedzerwa kwekuchengetedza alkali aid mu oxidation kana kunaya kwezvicherwa izvi zvinokuvadza. Izvi hazvisi kungowedzera kushanda kwese kwemaitiro ekuchera asiwo zvinobatsira pakuchengetedza uye kuchengetedza kwezvakatipoteredza kwekushanda.

mhedziso

Iyo cyanide goridhe kudhirowa maitiro inzira yakaomesesa inoda kunzwisisa kwakadzama kweakasiyana makemikari kudyidzana uye maparamita ekushanda. Sodium cyanide, sechinhu chakakosha, inoita basa rakakosha mukubudirira kudzoreredza goridhe kubva mumatombo. Nekudzora zvinhu zvakaita senge cyanide, mazinga eokisijeni, alkalinity, uye nguva yekugadzirisa, mashandiro emigodhi anogona kukwidziridza kuedza kwavo kuburitsa goridhe.

Uyezve, kukosha kwekudzivirira alkali mukudzikamisa cyanide mhinduro uye kuderedza mhedzisiro yemaminerari anokuvadza haigone kufuratirwa. Sezvo indasitiri yezvicherwa ichiramba ichishanduka, kunzwisiswa kwakakwana kwemaitiro aya nemakomponi kuchave kwakakosha pakuona kuti kune kuchengetedzwa, kwakanyatsoshanda, uye nekuchengetedza nharaunda maitiro ekuchera goridhe.

Muchidimbu, nepo sodium cyanide ichiwanzo kutariswa kuburikidza nelenzi yehupfu hwayo, kukosha kwayo mukuita kwekubvisa goridhe kwakakosha. Nekubata ruzivo rwakawanda rwakatenderedza nzira iyi, vane chekuita neindasitiri yezvicherwa vanogona kufamba zviri nani kuoma kwekudzoserwa kwegoridhe uye kubatsira mukufambisira mberi kwemaitiro emigodhi.
