Gold extraction refers to the processes required to extract gold from its ores. This may require a gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes However, froth flotation processes may also be used to concentrate the gold. The appearance is typical of very good gold-quartz ore.
