Aikace-aikace da Muhimmancin Sodium Cyanide a cikin Tsarin Ma'adinai

Sodium cyanide , wani sinadari mai kama da na halitta, yana taka muhimmiyar rawa a cikin tsarin cyanidation a cikin masana'antar haƙar zinare. Amfaninsa yana da bambanci kuma yana da mahimmanci wajen haƙo ƙarfe masu daraja daga ma'adanai.

Zinare Ore Leaching

Ɗaya daga cikin manyan amfani da Sodium cyanide ke yi shine a zubar da ma'adinan zinariya. A cikin wannan tsari, ana haɗa ma'adinan zinariya, bayan an niƙa shi aka niƙa shi ya zama ƙananan ƙwayoyin cuta, yana haɗuwa da wani ruwan da ke ɗauke da Sodium Cyanide . Haɗakar sinadarai tana faruwa tsakanin sodium cyanide da zinariyar da ke cikin ma'adinan, wanda ke haifar da samuwar ions na cyanide na zinariya, waɗanda daga nan ake narkar da su a cikin ruwan. Wannan tsari, wanda aka sani da Cyanide leaching , muhimmin mataki ne na samar da ma'adinan zinariya. Ana iya sauƙaƙe daidaiton sinadarai don amsawar tsakanin zinariya, oxygen, da sodium cyanide a cikin ruwan da ke cikin ruwan kamar haka: 4Au + 8NaCN + O₂ + 2H₂O → 4Na[Au(CN)₂] + 4NaOH. Wannan haɗakar tana ba da damar zinare, wanda galibi yake a cikin ƙarancin yawan ma'adinan, ya narke yadda ya kamata kuma ya rabu da sauran ma'adanai.

Hakar Zinariya

Bayan aikin leaching na cyanide, ana tattara maganin da ke ɗauke da narkar da zinare kuma ana yin ƙarin jiyya don zurfafa zinar. Sodium cyanide yana aiki azaman hazo a wannan matakin. Yana amsawa tare da ions chloride na gwal a cikin maganin don samar da hadaddun cyanide na zinariya. Bayan haka, ana amfani da hanyoyi daban-daban don fitar da gwal daga waɗannan rukunin gidaje. Wata hanya ta gama gari ita ce amfani da ƙurar zinc ko wasu abubuwan ragewa. Zinc yana kawar da zinare daga hadadden cyanide na gwal, wanda ke haifar da hazo na gwal na ƙarfe. Ana iya wakilta martanin kamar: 2Na[Au(CN)₂] + Zn → 2Au + Na₂[Zn(CN)₄]. Wannan tsari yana ba da damar dawo da zinari mai girma - mai tsabta daga maganin leach.

Leaching na Sauran Karfe Karfe

Bayan zinare, sodium cyanide yana kuma samun amfani a cikin zubar da wasu ma'adanai na ƙarfe. Misali, a yanayin azurfa, bayan cire cyanide, ana iya amfani da sodium cyanide a matsayin wakilin cirewa don fitar da azurfa daga maganin. Kamar yadda tsarin cire Gold ke yi, azurfa yana samar da hadaddun cyanide a gaban sodium cyanide. Halayen da ke tsakanin azurfa, sodium cyanide, da oxygen a cikin maganin ruwa yayi kama da na zinariya: 4Ag + 8NaCN + O₂ + 2H₂O → 4Na[Ag(CN)₂] + 4NaOH. Ana iya ƙara sarrafa waɗannan hadaddun cyanide na azurfa don samun azurfar ƙarfe.

A ƙarshe, sinadarin sodium cyanide sinadari ne mai matuƙar muhimmanci a masana'antar sarrafa ma'adanai , musamman a fannin haƙo ƙarfe masu daraja kamar zinariya da azurfa. Duk da haka, yana da muhimmanci a lura cewa saboda yanayinsa mai guba, dole ne a aiwatar da tsauraran matakan tsaro da kare muhalli yayin amfani da shi a ayyukan haƙar ma'adinai don hana duk wani lahani ga lafiyar ɗan adam da muhalli.
