more. If placer deposits contain both gold and a heavy radioactive mineral like monazite, the radiation counter can lead to the gold concentrations by detecting the monazite that is concentrated with it. A "black light," which is commonly used in prospecting for scheelite (an ore of tungsten), also is useful in identifying fluorescent

· Gold/silver base metal concentrate deportment. Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 60-70% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.
FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES
of the individual gold particles in the ore. Relatively coarse gold particles that are liberated from the gangue mineral phase by crushing and grinding are readily recovered by gravity techniques, because of the large difference in specific gravity between gold (SG 19.3) and most gangue minerals (SG 2 to 3).
When primary gold deposits are eroded away by weather (temperature, wind, water) over millions of years, it is referred to as secondary deposits. The gold is flushed out of the rock and accumulates with other heavy minerals as fine gold dust or as small grains, the so-called "nuggets", in the shallows of streams and rivers.

extents. Native gold occurrences vary widely in particle size and mineral association. Gold deposits can be classified into two primary classes: placer, where the gold has already been liberated from the host rock by natural weathering, typically by water erosion; and hard rock (or lode), where the gold is still locked within the host rock.
