Geochemical Analysis – Au +33

Geological Analysis (for Soils, Sediments, Rocks and Drill Core)

Geochemical analysis is inexpensive package that is useful for geochemical exploration, it provides total analysis where elements are activated even when they are in the most refractory minerals. The method does not require fine pulverising and is therefore less vulnerable to loss of gold onto pulveriser surfaces or sample loss. This is an extremely sensitive (low ppb to low ppm range) trace method but it is not just a trace element technique since neutron activation analysis (NAA) is also capable of reporting at per cent levels.
