Aug 21, 2020 Since sodium cyanide reacts very strongly with many copper minerals, it generally need 2.3 to 3.4 grams of cyanide to dissolve 1 gram of copper. (3) If the raw gold ore contains sphalerite and smithsonite, it will also react with sodium cyanide to form zinc cyanate and carbonate. The reaction formula is as follows: ZnS+4NaCN→Na2[Zn(CN)4]+Na2S
