Mhedzisiro yeMagiredhi Akasiyana Ore paKushandiswa kweSodium Cyanide muKushanda Kwemigodhi.

Munzvimbo yemugodhi, kunyanya mumatanho ekuchera goridhe uko cyanidation inzira yakajairika, kunzwisisa hukama huripo. Ore giredhi uye Sodium Cyanide kushandiswa kwakakosha. Sodium cyanide inoita basa rakakosha mukunyungudutsa goridhe kubva kune ore matrix, asi huwandu hunodiwa hunogona kusiyana zvakanyanya zvichienderana negiredhi resimbi iri kugadziriswa.

Kunzwisisa Ore Giredhi

Ore giredhi inoreva kuwanda kwechicherwa chakakosha, segoridhe, mukati mesimbi. Yakakwira-giredhi ores ine huwandu hwakati wandei hwemaminerari anodiwa, nepo yakaderera-giredhi ores ine yakanyanya kuderera. Semuenzaniso, ore yegoridhe yegiredhi repamusoro inogona kunge iine magiramu akati wandei egoridhe patani ye ore, nepo ore yegiredhi yakaderera inogona kuva isingasviki giramu rimwe patani.

Iyo Cyanidation process

The Cyanidation nzira tizvishandise sodium cyanide mhinduro dzekuita negoridhe mune ore. Muhupo hweokisijeni, iyo cyanide ions mu Sodium cyanide mushonga unosanganisa negoridhe kuti uite soluble complex. Iyi kemikari inoita inobvumira kuti goridhe riparadzaniswe kubva kune ore matrix, zvichiita kuti zvive nyore kubvisa. Iyo nzira inoshandiswa zvakanyanya nekuti inoshanda mukubvisa goridhe kubva mumhando dzakasiyana dzematombo.

Impact yeOre Giredhi paSodium Cyanide Consumption

High - Grade Ores

Lower Relative Consumption: Paunenge uchibata nepamusoro-giredhi ores, huwandu hwesodium cyanide inodiwa payuniti yemaminerari anokosha (semuenzaniso, pagiramu yegoridhe) kazhinji yakaderera. Izvi zvinodaro nekuti kune huwandu hwepamusoro hwechinangwa cheminerari mune vhoriyamu diki yeore. Semuyenzaniso, kana chicherwa chegoridhe chepamusoro chine magiramu gumi egoridhe patani, uye zvinoda 10 kg ye sodium cyanide patani ye ore kuti iwane chiyero chekuchera, Kushandiswa kwe sodium cyanide pagiramu regoridhe i 0.2 kg. Huwandu hushoma hwegangue (iyo isiri-yakakosha zvicherwa muore) mune yakakwira-giredhi ores zvinoreva kuti kune mashoma maitiro epadivi anogona kudya cyanide.

Faster Reaction Kinetics: High-giredhi ores inowanzoita nekukurumidza neiyo cyanide mhinduro. Iyo yakakwira yekumisikidzwa kwemaminerari inotangwa inopa mamwe masaiti eiyo cyanide - kuita kwegoridhe kuitika. Nekuda kweizvozvo, iyo yekubvisa maitiro inogona kupedzwa munguva pfupi, izvo zvinogona zvakare kubatsira kudzikisa yakazara cyanide kushandiswa. Izvi zvinodaro nekuti iyo cyanide mhinduro yakarebesa ichisangana neore, inozonyanya kudyiwa nemabatiro epadivi senge hydrolysis kana kuita nehumwe hutsvina mune ore.

Yakaderera - Grade Ores

Higher Relative Consumption: Yakaderera-giredhi ores kazhinji inoda huwandu hwepamusoro hwesodium cyanide payuniti yemaminerari akakosha. Funga nezvegoridhe regiredhi rakaderera rine 0.5 magiramu egoridhe patani. Kuti uwane mwero wekuchera unonzwisisika, ungangoda 1.5 kg ye sodium cyanide patani ye ore. Muchiitiko ichi, iyo sodium cyanide inoshandiswa pagiramu yegoridhe ndeye 3 kg, iyo yakanyanya kukwirira kupfuura yemuenzaniso wepamusoro wegiredhi. Chikonzero cheizvi ndechekuti kune huwandu hukuru hwemaminerari e gangue mune yakaderera-giredhi ores. Aya maminerari e gangue anogona kuita ne cyanide, kungave nekugadzira macomplexes kana nekushandisa oxygen mumhinduro, izvo zviri zviviri zvinowedzera cyanide inodiwa.

Zvishoma Zvinoita Maitiro: Maitiro ekubvisa kune yakaderera-giredhi ores anowanzo kunonoka. Kudzikira kwechicherwa chinoreva kuti maion ecyanide anofanirwa kutsvaga nepakati pehuwandu hwematombo kuti awane uye aite negoridhe. Iyi nguva yakareba yekuita nguva inogona kutungamirira mukuwedzera kushandiswa kwecyanide nekuda kwekuita kwemativi. Pamusoro pezvo, mune zvimwe zviitiko, kutsiva kunonoka kwekuita mwero, yakakwira cyanide concentrations inogona kushandiswa mumhinduro, ichiwedzera kuwedzera kushandiswa kwese.

Zvimwe Zvinokanganisa Hukama

Mineralogy yeOre: Kuvapo kwemamwe mamineral muore kunogona kukanganisa zvakanyanya kushandiswa kwecyanide zvisinei negiredhi reore. Zvicherwa zvakaita semhangura, zinc, arsenic, uye antimony zvinogona kuita necyanide, zvichigadzira macomplexes akatsiga zvobva zvapedza cyanide yaizowanikwa pakutorwa kwegoridhe. Semuenzaniso, zvicherwa zvemhangura zvinogona kuita necyanide kuumba mhangura - cyanide complexes, uye kana ore yacho iine huwandu hwakakura hwemhangura, kushandiswa kwecyanide kuchawedzera zvakanyanya, kunyangwe kune yakakwirira-giredhi goridhe ores.

Particle Saizi uye Surface Nzvimbo: Saizi yezvimedu zveore nenzvimbo yadzo inotambawo basa. Ores dzakatsetseka dzine nzvimbo yakakura pamusoro, iyo inogona kusimudzira kusangana pakati pemushonga wecyanide nezvidimbu zvegoridhe. Nekudaro, kana ore yapera - pasi, inogona zvakare kuwedzera huwandu hwemaminerari e gangue anoburitswa uye anowanikwa kuita necyanide. Ichi chinhu chinogona kukanganisa kushandiswa kwecyanide zvakasiyana kune yakakwira - uye yakaderera - giredhi ores, asi kazhinji, kutonga kwakaringana kwehukuru hwechikamu kwakakosha kukwirisa kushandiswa kwecyanide.

mhedziso

Mukupfupisa, giredhi reiyo ore rine simba rakakura pahuwandu hwesodium cyanide inodiwa mukuita cyanidation. Yepamusoro-giredhi ores inowanzoda shoma sodium cyanide pachikamu cheminerari yakakosha uye inokurumidza kuita kinetics, nepo yakaderera-giredhi ores inoda huwandu hwepamusoro hwecyanide uye kazhinji inononoka kuita mareti. Nekudaro, zvimwe zvinhu zvakaita senge mineralogy yeore uye saizi yechidimbu inodawo kunyatsotariswa pakusarudza iyo yakakwana sodium cyanide dosage mumabasa emigodhi. Nekunzwisisa hukama uhwu, vashandi vemumigodhi vanogona kunyatsoita uye mutengo - zvinobudirira kutora zvicherwa zvakakosha uku vachideredza kukanganisa kwezvakatipoteredza kune chekuita nekushandiswa kwesodium cyanide.
