Air press (air tort)

This press is pretty good at concentrating your amalgam prior to processing. I purchased one of these at the Action Mining store when it was in Trona, California prior to them moving to Las Vegas. I had several pounds of amalgam with no retort, but only had nitric acid to do the final process of separating the gold from the mercury, (which I had also purchased from Action Mining). This press will get rid of the excess mercury so that what one has left is a clump of gold with a thin layer of mercury still attached. One does need to use a retort or nitric acid to complete the final separation/recovery. 35 years later, I once again have need of this press so have ordered yet another one. My old press, I use a thin circle of leather chamois, which was the way it was used prior to the filter pads one sees today. It is a very useful tool and well worth the investment. I do have a retort now a days for final processing. (4-Stars since one still has another step to finish after using this awesome press)!
