CONCENTRATION OF PLACER GOLD ORE The recovery of placer gold involves processing similar to the processing of most ores. First, the valuable material is sepa-rated from the valueless waste through concentration. The fi-nal concentrate, usually obtained by repeated processing, is smelted or otherwise refined into the final product. This report

MoreGold deposits can be grouped into two primary classes: placer deposits, where the gold is exposed from weathering and erosion, and hard rock, where the gold is still trapped within the host rock. Gold recovery methods for these two types of deposits vary greatly from simple panning to a complex network of grinding, chemical leaching, gravity concentration and more.
