Cyanide Kushandiswa muGoridhe Cyanidation Maitiro

he cyanidation process ibwe repakona mukutorwa kwegoridhe kubva mumatombo ayo. Kunzwisisa kushandiswa kwe sodium cyanide panguva iyi maitiro akakosha pakugadzirisa kushanda zvakanaka uye kuderedza kukanganiswa kwezvakatipoteredza. Ichi chinyorwa chinoongorora nzira dzakasiyana-siyana dzinobatsira mukudyiwa kwe Sodium Cyanide mu goridhe cyanidation Process.

1. Autodecomposition

Sodium cyanide inopinda autodecomposition panguva yecyanidation process. Izvi zvinoguma nekuumbwa kwecarbonic acid, formic acid, uye ammonia. Iyo autodecomposition reactions inogona kuve yakaoma uye inokanganiswa nezvinhu zvakaita setembiricha, kutarisisa, uye kuvapo kwezvimwe zvinokonzeresa.

2. Hydrolysis

Hydrolysis ye Sodium cyanide ndiyo imwe nzira yakakosha yekushandisa. Kuita pakati pemvura uye sodium cyanide kunotevera:

(H2O + NaCN HCN + NaOH)

Hydrogen cyanide (HCN), inoputika uye ine muchetura musanganiswa, inogadzirwa panguva iyi yehydrolysis. Huwandu hweHCN hwakagadzirwa hunoenderana zvakanyanya nealkalinity yemushonga. Kana iyo pH kukosha ichichengetwa pa12 kana kupfuura, mhinduro yecyanide inoramba yakagadzikana. Nekudaro, zvinhu zvinogona kudzikisa pH kukosha, senge kabhoni dhaibhorosi kubva kumhepo, acids mumvura yekugadzira, divalent magnesium ions (Mg2 +) uye trivalent aluminium ions (A13 +), uye zvicherwa zvakasiyana-siyana mune ore kana oxidation zvigadzirwa zve sulfide zvicherwa, inogona kukurumidza kuita hydrolysis reaction.

3. Kuumbwa kweThiocyanate

Sodium cyanide inopindirana nemaminerari esulfide akadai sesimbi, mhangura, uye arsenic kuumba thiocyanate complexes. Aya maitiro anoshandura cyanide ions kuita zvisikwa zvishoma zvisingaite, zvinobudirira kuderedza huwandu hwemahara cyanide inowanikwa. kutorwa kwegoridhe. Kuumbwa kweaya thiocyanate complexes hakungowedzere kushandiswa kwe cyanide asiwo kunokanganisa kushanda kwese kweiyo goridhe cyanidation process.

Kunzwisisa nzira dzekushandisa idzi kunopa ruzivo rwakakosha kune vanoshanda muindasitiri yekuchera goridhe. Nekunyatsotarisisa uye nekudzora mamiriro eiyo cyanidation process, zvinokwanisika kudzikisira kushandiswa kwecyanide, kuvandudza goridhe kudzoreredza mitengo, uye kuderedza nharaunda tsoka yemabasa emigodhi yegoridhe.
