Methods Of Placer Mining

Many creeks and rivers in the west are still good gold producers. This book describes methods of extracting placer gold, including rocker, tom, sluice, electrostatic, and hydraulic concentrators.

Mining historian Kerby Jackson introduces us to a classic mining work in this important re-issue of "Elementary Methods of Placer Mining." Unavailable since 1944, this publication offers rare insights into the art of finding and recovering placer gold. Included in this small booklet are facts about the geology of alluvial gold deposits, the various types of placer gold deposits and the metals associated with placer gold. Also included are basic instructions on panning for gold, the use of sluice boxes, rocker boxes, as well as the recovery of fine gold by amalgamation plates and other methods. Basic plans to build your own mining equipment is also included. Written mainly for miners in Idaho, this short booklet also includes an overview of where to find gold in Idaho.
