Kunnawa Carbon Adsorption

Yawanci, ba a dawo da zinare kai tsaye ba. Madadin haka, ana niƙa ma'adinan don fitar da zinare, wanda daga nan zai yi aiki da Sodium Cyanide a cikin wani tsari da ake kira cyanidation. Tsarin yana da alaƙa da waɗannan halayen sinadarai: Bayan an samar da hadaddun ƙarfe (NaAu(CN)2), carbon da aka kunna zai sha hadaddun cyanide na zinare daga rafin ɗaukar zinare ( abin sha mai ciki ).

4 Au + 8(NaCN) + O ₂ + H ₂ O = 4 NaAu(CN) ₂ + 4 NaOH

Zane da ke sama yana nuna ƊAƊA zinare a kan faranti na graphitic na carbon da aka kunna . Zinariya kaɗai ba ta narkewa, kuma ba za ta shanye ta cikin sauƙi ta hanyar carbon da aka kunna ba har sai ta yi cyanidate, ta samar da hadadden haɗin gwiwa na zinare- cyanide da ake kira dicyanoaurate. Wannan hadadden zinare-cyanide ne ke jan hankalin babban yankin saman da ake samu akan carbon da aka kunna, wanda ke ba da damar dabarun murmurewa iri-iri.
