| Abstract: | In HCl medium, cotton cellulose xanthate absorb the solution where the abandoned electronics circuit board is dissolved by the king water. Impurity are washed out by 6mol/L HCl. The AuCl 4 - is eluted with 5% Na 2SO 3 at a flow rate of 1mL/min.After the elute is concentrated, Au is precipitated by 20% Na 2SO 3. The gold of 99.59% purity is got. |
