Abstract - USGS

This model is designed for evaluating deposits where a gravity mill will be used to process ore that can be separated by gravity. Typical deposits where gravity mills are used include free milling gold, some tungsten, and other heavy mineral deposits. The model is valid for feed rates of 100 to 1,000 st/d. Recovery is assumed to be 93%.
