Gold Recovery 101 - Sepro Mineral Systems

Gold and silver contained inside some sulfides amalgamates poorly, and in those early days, amalgamation was the chief recovery method for hard rock ores. The old timers developed the pan processes where they ground up the ore and amalgam mixture for hours at a time (the Washoe Process), and for some ores that did the job.
