Abstract

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 oz/st Au was assumed, with a recovery of 88%. Mine-run ore is fed to a jaw crusher, then to a SAG mill for grinding. The ore is then run over a jig

Gold Statistics and Information

Gold has been treasured since ancient times for its beauty and permanence. Most of the gold that is fabricated today goes into the manufacture of jewelry. However, because of its superior electrical conductivity and resistance to corrosion and other desirable combinations of physical and chemical properties, gold also emerged in the late 20th century as an essential

A process whereby gold is extracted by "heaping" broken ore on sloping impermeable pads and continually applying to the heaps a weak cyanide solution which dissolves the contained gold. The gold-laden solution is then collected for gold recovery. High grade: Rich ore. As a verb, it refers to selective mining of the best ore in a deposit.

Gold has been recovered from some pretty lean ores, being profitably extracted from ores yielding less than two hundredths of an ounce in a ton of rock.
