Amfani da ferrous sulfate don magance wutsiyar a cikin ma'adinin zinare

Wutsiyar ruwan gwal na mines na gwal suna dauke da adadin Cyanide. Koyaya, ions mai ferrius a cikin sulfate ferrous iya amsawa tare da cyanide tare da wutsiya, kuma samar da feande da sauran abubuwa. Wannan amsawar na iya shafar sakamakon amsawa a karkashin wasu yanayi na waje. Misali, lura da cyanide-dauke da sharar sharar mai dauke da ferrous sulfate a karkashin high zazzabi, m ulvivet shin m, da m ultaniveret zai shafi amsawa. Cyean Cyeide yana da m, kuma a lokacin aiwatar da bayan gida, maganin ckindede sauƙi yana ganin koru na ruwa. Bari mu bincika tsarin aikin da sakamakon ƙara cyanide zuwa sulfate. Bari muyi wani gwaji don ƙara cyanide lokacin da akwai mai yawa sulfate. Wannan shine a faɗi, lokacin da aka ƙara wuce gona da iri na sulfate a cikin maganin cyanide, Cyanide za su juya cikin ɓacin rai na fee [Fe (CN (CN) 3] 3, wanda muke yawanci kira Blussian BluSsian. Tabbas, yayin aiwatar da wutsiyar solings a cikin kayan zinare, wasu kamfanoni ba sa zaɓi ƙara ferrous sulfate don magani, amma zaɓi don ƙara ferrious sulfide. Wasu kamfanoni sun zaɓi ƙara ƙarfe da jan ƙarfe a lokaci guda don samar da farin insolable feranode cyanide. Abin baƙin ƙarfe da sauri suna fama da isashshen oxygen daga iska, ya juya duhu mai launin shuɗi, kuma yana samar da ferricyanide.

Ana iya kammala ta hanyar gwaje-gwajen da mafi kyawun yanayin cire cyanide daga bayani tare da sulfate mai zurfi shine samun tsari wanda ke haifar da narkewa da kuma insolable mahadi. A yayin gwaji, mun lasafta shi na Molar rabo daga sakamakon sakamakon ferrous sulfate da CN-. Na farko, ana lissafta rabo bisa stoicometry da SP.39, amma mafi kyau duka rabo da muka samu ta hanyar lissafi ya kasance 0.5. . Mafi Kyawun PH don precititing blusian blues shine 5.5 zuwa 6.5. Gabaɗaya magana, oxygen na iya amfani da ƙarfe na ƙarfe don samar da ions don ferricyanide ions, wanda ya fi rashin lalacewa don cire cyanide. Because ferricyanate ion is quite unstable under acidic conditions, it will react to form ferrous pentacyano complex [Fe(CN)5H2O]3-, which is rapidly oxidized to ferricyanate ion Fe(CN). ) 63-. Waɗannan halayen suna faruwa a dabi'un PH a ƙasa 4. Bayan gwaje-gwajen, a ƙarshe muka yi amfani da hanyar magani ta hanyar amfani da cyanide daga wutsiya ƙimar pH ne na 5.5 zuwa 6.5. Darajar da yawa shine mafi dacewa, da rabo daga f zuwa CN-0.5 shine mafi dacewa don sarrafawa.
