Ask The Experts—Using classifiers
December 2010 by Chris RalphQ: I would like to know how to use a classifier when I dump my gravel into my sluice box. I would also like to know what sizes classifiers come in. I know that they are in sizes like -3/4. What does the “minus” in the size mean? Thanks for any help you can give me.

I am trying to find any information about using bubbles to separate platinum from sands and small particles. I think it has to have a surfactant in the process. Do you know of this bubble tech?
