THE MOST EFFICIENT CONCENTRATOR AVAILABLE IN THE INDUSTRY TODAY
Enough experience in the use of jigs in placer operation has been accumulated now to establish their application as the most modern and efficient way of recovering placer values. Comparisons of the work of jigs with that of riffles on many different operations in the United States as well as abroad and under various conditions have demonstrated that 5 to 40 percent higher recoveries can be obtained with jigs, with an average of about 15%.
It is in the placer ground that is characterized by the occurrence of extremely fine gold, of an excessive proportion of sand, or of a large amount of heavy constituents such as black sands (all deterrents to efficient recovery of Gold by riffles) that large operations as well as small have found the IRD Pan American Jig to be almost indespensable.
