Matanho ekudzikisa Sodium Cyanide Kushandisa Uchiri Kuchengetedza Mareti ekudzoreredza

Mumaindasitiri emigodhi nekubvisa simbi, sodium cyanide yagara iri chinhu chakakosha pakubvisa simbi dzinokosha dzakadai segoridhe nesirivha nekuda kwekushanda kwayo mukunyungudutsa simbi idzi. Zvisinei, kushandiswa kweSodium Cyanide kune njodzi huru dzezvakatipoteredza nekuchengetedzwa, kusanganisira mukana wekubuda kwecyanide uye kukuvara kwainogona kukonzera kunharaunda neutano hwevanhu. Sezvo mitemo yezvakatipoteredza iri kuramba ichioma, pane kudiwa kuri kukura kwekuderedza kushandiswa kweSodium cyanide pasina kuderedza mwero wekudzorerwa kwesimbi. Iyi blog post inoongorora nzira dzakasiyana siyana uye matekinoroji anogona kubatsira kuwana chiyero ichi chakapfava.

1. Optimize Leaching Maitiro

Maitiro ekuburitsa sodium cyanide ndeapo sodium cyanide inosangana neore kuti inyungudise simbi dzinovavarirwa. Nekugadzirisa ma parameter mukati memaitiro aya, kushandiswa kwecyanide kunogona kudzikiswa zvakanyanya.

1.1 Fine-Tune pH uye Oxygen Levels

Sodium cyanide inoshanda zvakanyanya mukati meiyo pH renji, kazhinji iri pakati pe10 ne11. Kutarisisa uye kunyatso kudzora pH yemushonga weleaching kunogona kuwedzera kuita reactivity kwecyanide. Pamusoro pezvo, okisijeni yakakosha kune oxidation reaction inoita kuti simbi iparare. Yakakwana aeration, kuburikidza nenzira dzakaita sekushandisa mhepo compressors kana okisijeni jekiseni masisitimu, inova nechokwadi chekuti oxidation process inofamba zvakanaka. Nekuchengetedza chiyero chakanaka chepH uye oksijeni, cyanide shoma inodiwa kuti iwane chiyero chakafanana chekubvisa simbi.

1.2 Shandisa Maitiro Ekutanga Kurapa

Kufanorapa iyo ore inogona kuita kuti iwedzere kutendeseka kune cyanide leaching, kuderedza iyo yakazara cyanide inodiwa. Semuenzaniso, kugocha kana bio-oxidation inogona kuputsa zvinhu zvinoramba zviri muore, zvichiburitsa mamwe masimbi anonangwa kumushonga wecyanide. Kudzvanya oxidation ndiyo imwe nzira inoshanda yepamberi yekurapa, iyo inogona kuwedzera pamusoro penzvimbo yeore zvimedu uye kuvandudza kusangana pakati pecyanide nesimbi, nekudaro kuwedzera kudzoreredza mitengo uchishandisa shoma cyanide.

2. Shandura neAlternative Reagents uye Additives

Kuongorora mamwe mareagents uye zvinowedzera zvinogona kupa zvinogoneka zvinotsiva kana zvinowedzera kune sodium cyanide, ichideredza kuvimba kwayo.

2.1 Shandisa Cyanide-Yemahara Leaching Agents

Mazhinji cyanide-isina leaching agents abuda sedzimwe nzira dzinogona kuitika. Thiosulfate, semuenzaniso, yakaratidza vimbiso mukuchera goridhe. Iyo haina muchetura kupfuura sodium cyanide uye inogona kuwana yakaenzana kudzoreredza mitengo pasi pemamiriro akakodzera. Thiosulfate leaching inonyanya kushanda mune ores ine yakakwira huwandu hwemhangura kana zvimwe zvinokanganisa zvinhu, izvo zvinogona kushandisa cyanide mumaitiro echinyakare. Imwe sarudzo ndeye thiourea, iyo inopawo imwe yakasarudzika yezvakatipoteredza yekubvisa simbi, kunyanya kana yakasanganiswa neakakodzera oxidants.

2.2 Batanidza Zvinowedzerwa

Zviwedzerwa zvinogona kuwedzera kushanda kwe sodium cyanide, zvichibvumira kuderedzwa kushandiswa. Lime, semuenzaniso, inowanzoshandiswa kugadzirisa pH yemhinduro yekuchenesa uye kudzivirira kuumbwa kwegasi rinokuvadza rehydrogen cyanide. Pamusoro pezvo, mamwe mapolymers uye ma surfactants anogona kuvandudza kupararira kwecyanide mune ore slurry, zvichiwedzera kugona kwekubatana pakati pecyanide nesimbi. Izvi zvinowedzera zvinogona kubatsira kuderedza kushandiswa kwecyanide kusvika pa20 - 30% uku uchichengetedza mitengo yekudzosa.

3. Kuvandudza Equipment uye Monitoring Systems

Kusimudzira michina uye kuita epamberi ekutarisa masisitimu anogona zvakare kubatsira mukudzikisa sodium cyanide kushandiswa.

3.1 Simudzira Leaching Reactors

Mazuva ano leaching reactors, akadai seagitated tank reactors ane yakagadziridzwa nzira dzekusanganisa, anogona kuve nechokwadi chekugovera kwakafanana kwecyanide mune ore slurry. Izvi zvinovandudza kushanda kwekuparara kwesimbi, zvichiita kuti kushandiswa kwe cyanide shoma. Continuous stirred-tank reactors (CSTRs) ine optimized impeller dhizaini inogona kuwedzera huwandu hwekutamisa mitengo, kuderedza nguva uye huwandu hwecyanide inodiwa kuti ipedze kubviswa kwesimbi.

3.2 Ita Yechokwadi-Nguva Monitoring

Masensa epamberi uye masisitimu ekutarisa anogona kuramba achiyera ma paramita senge cyanide concentration, pH, uye simbi yekunyungudika mazinga mukuita leaching process. Nekuva nedata-chaiyo-nguva, vashandisi vanogona kugadzirisa nekukurumidza kune cyanide dosage, kuve nechokwadi chekuti chete mari inodiwa ndiyo inoshandiswa. Otomatiki kudzora masisitimu anogona kubatanidzwa neaya ma sensor kuti anyatso kudzora kuwedzera kwe cyanide, kudzivirira kushandisa zvakanyanya uye optimize kudzoreredza mitengo.

4. Optimize Ore Kubata uye Kugadzirira

Kubata nekugadzirira matombo nemazvo kunogona kukanganisa kushandiswa kwecyanide uye huwandu hwekudzorerwa kwematombo acho.

4.1 Ore Kukuya Optimization

Kudzora saizi yesimbi kuburikidza nekukuya kwakakwenenzverwa kwakakosha. Finer particle sizes inowedzera nzvimbo inowanikwa kuti cyanide iite nemasimbi, asi kunyanya kugaya kunogona kutungamira mukuwedzera reagent kushandiswa. Nekutsvaga iyo yakakwana particle saizi yekugovera kuburikidza nekuyedza uye maitiro ekuenzanisa, huwandu hwecyanide hunodiwa kune inoshanda kudhirowa simbi hunogona kudzikiswa uchichengetedza yakakwirira kudzoreredza mitengo.

4.2 Ore Sorting Technologies

Kushandisa matekinoroji ekugadzirisa ore, senge X-ray fluorescence (XRF) kuronga kana kurongedza kwemaziso, kunogona kuparadzanisa ore yegiredhi repamusoro kubva kune yakaderera-giredhi ore isati yaitwa leaching process. Izvi zvinobvumira kudonhedzwa kwakanangwa kwezvikamu zvakakosha zveore, kuderedza huwandu hwese hwezvinhu zvinoda kurapwa necyanide nekudaro kuderedza kushandiswa kwecyanide.

Mukupedzisa, kuderedza kushandiswa kwesodium cyanide uku uchichengetedza mitengo yekudzoreredza idambudziko rakawanda rinoda musanganiswa wekugadzirisa maitiro, hunyanzvi hwekuvandudza tekinoroji, uye nekuchenjera manejimendi ekushanda. Nekushandisa nzira dzataurwa pamusoro apa, maindasitiri ekuchera migodhi nesimbi haangogone kuderedza mamiriro avo ezvakatipoteredza asiwo anogona kudzikisa mutengo wekushandisa mukufamba kwenguva. Sezvo tsvakiridzo ichienderera mberi, nzira nyowani uye dzinoshanda zvakanyanya dzingangobuda, dzichiwedzera kuvandudza kusimba kwemaitiro ekubvisa simbi.
