How to Purify Gold

Apr 24 2017In 1874 Dr Emil Wohlwill of the Norddeutsche Affinerie in Hamburg Germany developed a method to purify gold through electrolysis The unpurified gold ore is fashioned into a 100-ounce anode whereas pure gold strips make up the cathode The electrolyte solution is a mix of gold chloride and hydrochloric acid

Xanthate

Xanthate salts are produced by the reaction of an alkoxide salt with carbon disulfide The reaction involves the attack of the alkoxide nucleophile on the electrophile CS 2 Often the alkoxide is generated in situ by treating the alcohol with sodium or potassium hydroxide ROH + CS 2 + KOH → ROCS 2 K + H 2 O For example sodium ethoxide gives sodium ethyl xanthate
