Drywashing for Fine Gold | ICMJs Prospecting and Mining Journal

I try to avoid processing too much clay-bound material in favor of more loamy or sandy conditions. In loamy or sandy conditions, silty clays can be very minimal, allowing for fine placer gold particles to be free within the detrital alluvium, and the alluvium itself is pretty free with very little binding to itself. As a result, there is an.

Estimating process design gold extraction, leach residence time and .

As with high clay-bearing ore, where pulp viscosity can hinder mass transfer, minimizing the influence of test equipment on gold extraction kinetics may require low pulp densities. This introduces interpretative complexity since cyanide consumption changes as a function of pulp density. Activated carbon also consumes.
