Kurapa kweCyanide muGoridhe Leaching Tailings

Kuwanda kweCyanidation uye Ngozi yeCyanide

Cyanidation inoshandiswa zvakanyanya nehuwandu hwemigodhi yegoridhe pasi rose uye inogona kuramba yakapararira mumakore anotevera. Zvisinei, Cyanide chinhu chine muchetura chinosvibisa. Kuvapo kwayo mumvura yetsvina uye miswe inogona kukanganisa zvakanyanya vanhu nenharaunda. Nokudaro, zvakakosha kudzora izvi zvinosvibisa.

Cyanide Leaching process uye Yayo By - zvigadzirwa

Cyanide leaching inoshandura goridhe kuita mvura - inonyungudika cyanide complexes uye parizvino ndiyo nzira yakajairika uye inoshanda yekubvisa goridhe kubva mumatombo. Kuita uku kunoda kuwanda kwe cyanide kuti iwedzere kudzoreredza goridhe, kugadzira cyanide - ine tsvina muchimiro chemiswe nemvura. Yemahara cyanide, iyo yekutanga ne-chigadzirwa mumetallurgical process, inoonekwa seyakanyanya muchetura fomu yecyanide sezvo inogona kukonzeresa zvinokuvadza kunyangwe pakudzika kwakadzika. Mamwe marudzi ecyanide anogona kunyungudika zviri nyore kuita cyanide yemahara pasi pemamiriro e acidic.

Iko Kudikanwa Kwekurapa Cyanide - ine Miswe

Iko kudzoreredzwa kwechisikigo kwecyanide mumaswe kune bio - isingakuvadzi nhanho inotora nguva yakareba. Naizvozvo, cyanide - ine miswe inofanirwa kurapwa isati yaburitswa mukati menharaunda kudzivirira kukanganisa kwakashata panharaunda yekugamuchira. Kuparara kwe cyanide mukati Gold leaching tailings rave riri rimwe rematambudziko makuru akatarisana nemigodhi yegoridhe mumakumi mashoma emakore apfuura. Nekudaro, kurapwa kwakaringana kwecyanide mumisara kwakakosha kudzivirira kana kudzikisa nharaunda uye hutano matambudziko.

Maitiro Aripo Ekurapa eCyanide

Kwemakore, akati wandei ebhayoloji, emuviri, uye makemikari matekiniki, pamwe ne electrolytic oxidation uye dzimwe nzira dzekuora kana kudzoreredza cyanide, dzakagadzirwa kurapa cyanide mhinduro. Parizvino, matekiniki anoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri ekuora kwecyanide anosanganisira INCO process, alkaline chlorination process, activated carbon process, ozonation process, iyo hydrogen peroxide oxidation process, uye hydrogen cyanide kupora. Iyo INCO uye alkaline chlorination maitiro anoshandiswa kubvisa yakakwira -concentration cyanide asi haigone kusvibisa cyanide zvachose. Activated kabhoni inogona adsorb uye aggregate cyanide asi haigone kuiparadza. Iyo ozonation uye hydrogen peroxide oxidation maitiro anoshandiswa kurapa yakaderera - concentration cyanide ine kushoma kwechipiri kusvibiswa, asi iwo anodhura. Hydrogen cyanide kudzoreredza inogona kuderedza cyanide zvemukati uye mutengo asi haizadzise zvinodiwa kuti tailings backfilling.

Backfilling Technology uye Cyanide Removal Research

Backfilling tekinoroji ndiyo yakanakisa sarudzo kuti migodhi iparadze mabhodhoro ezviwanikwa, nharaunda, uye chengetedzo. Nekudaro, zvinhu zvinokuvadza senge zvakasara zvesimbi zvinhu uye zvinonyungudutsa mugoridhe - leaching tailings dzinofanirwa kunyatsogadziriswa isati yadzoreredzwa kudzivirira kusvibiswa kwemvura yepasi. Tsvagiridzo yekubvisa cyanide yakanyanya kutarisisa pamvura yetsvina yemaindasitiri. Tsvagiridzo yekubvisa cyanide mugoridhe - leaching tailings, kusanganisira mvura yetsvina uye miswe, ichiri shoma. Iko kuumbwa kwemaminerari egoridhe ores kwakaomarara, uye makemikari zvinhu zvakaita secyanide, activated kabhoni poda, uye hydrogen peroxide inowedzerwa kune iyo beneficiation process, zvichiita kuti kuumbwa kwemiswe kuve kuoma. Yakawanda yeyakasara cyanide mumiswe inoshambadzirwa zvakasimba pamusoro pemaminerari, uye zvishoma chete zvemahara cyanide uye hydrolyzed yakaoma cyanide inogona kupinda muleachate. Naizvozvo, zvinodikanwa kutsvaga nzira dzinoshanda dzekubvisa cyanide.

Iko kuomarara kweCN⁻ Kuparara uye Remangwana Retsvagiridzo Yekutungamira

Kuora kwakakodzera kweCN⁻ inzira yakaoma. Zvinoda kusanganiswa kwenzira dzakawanda dzekuvandudza kushanda kwekurapa uye kufunga nezvehupfumi hwekurapa. Kushandisa nzira dzakasanganiswa kubvisa cyanide igwara rinovimbisa rekutsvaga mune ramangwana.
