Abstract - USGS

This model is designed for evaluating deposits where a gold ore requires fluid-bed roasting, typically carbona­ceous or sulfide ore. The cost equations are valid for ore tonnage capacities of 1,000 to 20,000 st/d. For the model, a grade of 0.058 oz/st Au was assumed, with a recovery of 88%.
