Summary

The method described is based on treatment of the finely ground ore sample with concentrated nitric acid, removal of the soluble salts and finally extraction of the residue by hydrogen chloride, containing some chlorine. The gold in the last solution is precipitated together with mercury sulphide and then determined dokimastically. Results are satisfactory.
