Izvo Zvikumbiro uye Kukosha kweSodium Cyanide muMineral Processing

Sodium cyanide, inorganic compound, inoita basa rakakosha mukuita cyanidation mukati meindasitiri yekuchera goridhe. Mashandisirwo ayo akasiyana uye akakosha mukutorwa kwesimbi dzinokosha kubva mu ores.

Gold Ore Leaching

Imwe yekutanga kushandiswa kwe Sodium cyanide iri mukucherwa kwegoridhe. Mukuita uku, ore yegoridhe, mushure mekupwanyiwa nekugayiwa kuita zvidimbu zvidimbu, inounzwa musanganiswa nemushonga wemvura une. Sodium Cyanide. Kemikari inoitika pakati sodium cyanide uye goridhe iri mumatombo, zvichiita kuti pave negoridhe cyanide ions, iyo inobva yanyungudutswa mumushonga. Iyi nzira, inozivikanwa se Cyanide leaching, inhanho yakakosha uye yakakosha mukubatsirwa kwegoridhe ore. Kemikari equation yemaitiro pakati pegoridhe, okisijeni, uye sodium cyanide mumushonga wemvura unogona kurerutswa se: 4Au + 8NaCN + O₂ + 2H₂O → 4Na[Au(CN)₂] + 4NaOH. Kuita uku kunobvumira goridhe, iro rinowanzo wanikwa munzvimbo dzakaderera muore, kunyatsonyungudika uye kuparadzaniswa kubva kune mamwe mamineral.

Kuchera Goridhe

Kutevera iyo cyanide leaching process, mhinduro ine goridhe yakanyungudika inounganidzwa uye inoiswa mukumwe kurapwa kuti iwedzere goridhe. Sodium cyanide inoshanda seyakagadzika padanho iri. Inopindirana neiyo goridhe chloride ions mumhinduro kuumba goridhe cyanide complexes. Zvadaro, nzira dzakasiyana-siyana dzinoshandiswa kuburitsa goridhe kubva kune aya macomplexes. Imwe nzira yakajairika ndeyekushandisa zinc guruva kana zvimwe zvinoderedza. Zinc inobvisa goridhe kubva kugoridhe cyanide, zvichikonzera kunaya kwegoridhe resimbi. Mhedzisiro yacho inogona kumiririrwa se: 2Na[Au(CN)₂] + Zn → 2Au + Na₂[Zn(CN)₄]. Iyi nzira inogonesa kudzoreredza kwepamusoro-kuchena goridhe kubva kune leach mhinduro.

Leaching yemamwe Metal Ores

Kupfuura goridhe, sodium cyanide inowanawo kushanda mukudonha kwemamwe masimbi esimbi. Semuyenzaniso, kana iri sirivheri ores, mushure me cyanide leaching, sodium cyanide inogona kushandiswa semushonga wekubvisa kuburitsa sirivha kubva mumhinduro. Zvakafanana ne Gold extractionn process, sirivheri inoumba cyanide complexes pamberi pe sodium cyanide. Kuita pakati pesirivheri, sodium cyanide, uye okisijeni mumushonga wemvura yakafanana neyegoridhe: 4Ag + 8NaCN + O₂ + 2H₂O → 4Na[Ag(CN)₂] + 4NaOH. Iyi silver cyanide complexes inogona kuenderera mberi kugadziriswa kuti iwane simbi yesirivha.

Mukupedzisa, sodium cyanide ikemikari inokosha mu Mineral processing indasitiri, kunyanya mukucherwa kwesimbi dzinokosha segoridhe nesirivha. Nekudaro, zvakakosha kuziva kuti nekuda kwehunhu hwayo hwehupfu, kuchengetedzwa kwakasimba uye matanho ekuchengetedza kwezvakatipoteredza anofanirwa kuitwa panguva yekushandiswa kwayo mumabasa emigodhi kudzivirira chero kukuvadza kuhutano hwevanhu uye nharaunda.
