Newbery–Vautin chlorination process - Wikipedia

Claude Theodore James Vautin, a man of much practical experience of gold mining and extraction in Queensland, Australia, together with James Cosmo Newbery, analytical chemist to the government of Victoria, have developed a process which they claim to combine all the advantages of the foregoing methods, and by the addition of certain improvements in the machinery and mode of treatment to overcome the difficulties which have hitherto prevented the general adoption of the chlorination process.

The Extraction of Gold by Amalgamation and Chlorination

The Extraction of Gold by Amalgamation and Chlorination By RALPH W. BIRRELL University of Melbourne he gold ores found above the waterline in the Lachlan Fold Belt of south eastern Australia in the 1850s, were free milling, meaning that most of the gold could be easily separated from the quartz by crushing, followed by amalgamation with mercury. 1 The particles of gold were relatively large ...

US4353740A - Chlorine extraction of gold - Google Patents

A process for treating a particulated gold bearing ore to recover the gold therein is disclosed. The process includes roasting the ore to remove sulfides as sulfur dioxide followed by chlorination of the ore at a temperature of about 350° C. in the presence of iron to form a mixture of volatile gold chlorides and volatile gold-iron chlorides in the chlorine off gases followed by condensing ...

The Chlorination of Gold Ores.

The Chlorination of Gold Ores. By Mr. Donald Clark, M.M.E., B.C.E. The ideal method for extracting fine gold would be to dis-solve out the gold with some solvent which would not attack other minerals present. The solvents known 6o years ago were chlorine, bromine, and cyanide of potassium. Yet in spite of this knowledge it was only comparatively recently that such solvents were successfully ...
