FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES
refractory gold ore. Ones under 80% are considered refractory. In assessing the economic benefit of the extra processing that must be done to improve recovery from refractory or partially refractory ores, one must consider the incremental improvement in gold recovery versus standard grinding and cyanidation, and the incremental increase in costs to achieve this improvement.
