The Chlorination of Gold Ores.

The history of the chlorination process is interesting, and not commonly known, so that a brief account of it will not be out of place. Dr. Percy—rightly called the father of English Metallurgy —in 1848 read a paper on the value of chlorine as a means of extracting gold from ores ; in the same paper he suggested the use of hyposulphite of sodium as an after treatment for the extraction
