Carlin Type gold is a special gold ore, in which gold particles of 0.1 ~ 0.01 µm in size are disseminated in rock minerals, such as pyrite, illite, and montmorillite.
The microsized gold can not be observed, even with the use of a common microscope, hence the name "invisible gold" or "microsized disseminating gold".
This type of gold has deposits all over the world.

By studying the effects of serial reagents on gold ore, our scientists have gradually selected out reagent combinations, which have have various functions for gold ore.
The absorboaggregation flotation technique can effectively separate the Carlin Type gold from other minerals and impurities.
Experimental results have proven a good rate of gold recovery through this new technique.
