Assay Method of Zinc in Cyanide Leach Solution

To ascertain the presence of zinc add a few drops of sodium sulphide solution to 50 cc of the solution to be tested (which should be strongly alkaline), and heat to boiling point. If zinc is present it will come down as a flocculent white precipitate. It sometimes happens that a cyanide solution will contain an appreciable quantity of alumina

Why does Zinc react with copper sulphate solution

Zinc metal can displace copper ions from a solution of copper(II) sulphate. Copper metal and a solution of zinc(II) sulphate are produced. The equation shows that the zinc atoms (metal) have formed positively charged zinc ions, i.e., they have lost electrons. This means the zinc atoms have been oxidised.
