The large majority use amalgamation either as the final process to extract gold from gravity concentrates or from the whole ore. This latter …
PLACER GOLD RECOVERY METHODS
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
