There is no fixed formula for setting up the proper air flows and downward pitch on the recovery system of a drywasher. A lot depends upon the nature of the material that you are processing, how heavy it is, whether or not the material is angular or waterworn and the purity (specific gravity) and size of the gold being recovered. Each of these variables is likely to affect how you must set ...

gold, referred to as flour, flood, or colloidal gold, is lost in processing. Early miners recovered no more than 60% of assayed gold values, and as late as 1945 recovery of free gold averaged only 7075% (Spiller, 1983). Moreover, it is likely that most remaining placer deposits have a higher percentage
