Silver Amalgamation, James A. Pack

Professional Degree Theses

"The process of amalgamation is one of the oldest known methods of extracting silver from its ores. The process arose from the finding of rich silver ores in districts where little or no fuel existed.

This method of silver extraction has been known and used for over three hundred years; but the method of pan amalgamation which came into use much later and has been so fully developed under American management is the one which we will here consider.

The process of pan amalgamation is peculiarly adapted to certain mining districts of the western territory of the United States"--page 2.
