  • The cyanide process of gold extraction involves leaching

     · The cyanide process of gold extraction involves leaching out gold from its ore with CNin the presence of Q in water to form R. Subsequently R is treated with T to obtain Au and Z. Choose the correct option(s) (A) Q is O 2 (B) R is Au(CN) 4 (C) Z is Zn(CN)4 2– (D) T is Zn

     · Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.
