Ruzivo rwakajairwa nezve cyanide sodium kutorwa kwegoridhe yaungasaziva

Munyika yekucherwa kwegoridhe, the Cyanide extract process inzira yakakosha inoshandiswa kuburitsa goridhe kubva mumatombo. Nepo vazhinji vangave vachiziva nezve izwi rekuti "cyanide," kuomarara kwekushandiswa kwayo mukubvisa goridhe kunowanzo furatirwa. Ichi chinyorwa chine chinangwa chekujekesa ruzivo rwevanhu vese vakatenderedza Sodium cyanide nebasa rayo mu Goridhe kutorwa maitiro, kuve nechokwadi chekunzwisisa kwakakwana kweiyi nzira yakakosha.

Iyo Cyanide Gold Extraction process

Iyo cyanide yegoridhe yekubvisa maitiro inosanganisira akati wandei akakosha matanho, imwe neimwe ichida kunyatso kudzora kweakasiyana ma paramita kuti ave nechokwadi chemhedzisiro. Zvinhu zvekutanga zvinofanirwa kutariswa zvinosanganisira cyanide concentration, oxygen concentration, alkalinity, uye nguva inodiwa yekuparara. Zvinhu izvi zvakakosha pakuwana hunhu hunodiwa hwe kupora kwegoridhe.

1. Leaching: Danho rekutanga mukuita uku kudonha, uko goridhe rakasimba rinonyungudutswa mune ine oxygen-ine cyanide mhinduro. Iyi mhinduro inobvumira kubviswa kwegoridhe kubva kune ore, kunyatsoiparadzanisa kubva kune mamwe maminera.

2. Kushamba: Kutevera leaching, danho rinotevera kugeza. Kuita uku kunosanganisira kudzoreredza mhinduro ine goridhe mushure mekunyungudika nekusuka goridhe rakanyungudutswa kubva pamusoro pematombo. Chinangwa ndechekuzadzisa kuparadzaniswa kwakasimba-mvura, kuve nechokwadi kuti goridhe rinonyatsoparadzaniswa kubva kune zvakasara.

3. Kutsiva: Nhanho yekupedzisira mukuita kwekubvisa ndeyekutsiva, uko mhinduro ine goridhe inobatwa nesimbi zinc. Iyi nhanho inoderedza uye inoderedza goridhe, ichibvumira kupora kwayo muchimiro chakasimba.

Key Compounds muCyanide Gold Extraction

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

1.Cyanide

Cyanide ndiyo ibwe rekona rekuita leaching. Mumaindasitiri ekushandisa, akati wandei mafomu ecyanide anoshandiswa, kusanganisira 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.

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.
