Jasper County Democrat, Volume 1, Number 29, Rensselaer, Jasper County, 29 October 1898 — Extracting Gold. [ARTICLE]

Extracting Gold.

Gold is now extracted by mixing the ore with common salt and sulphuric acid, then adding a solution of permanganate of potash. Hydrochloric acid Is formed, and chlorine is liberated to combine with the gold, forming chloride of gold. This new method as employed at Mount Morgan, Queensland, Is said to have advantages over the amalgamation and cyanide processes. It Is more searching than mercury, and can be applied to ores containing copper.
