In Benguet province, a group of miners have been using the mercury-free gravity-borax method (GBM) for gold extraction for decades. This method basically requires the same equipment as the amalgamation methods. However, after the rod milling, an ore concentrate holding the heavy minerals is produced by using a launder (gold sluice) and a gold washing pan.
Such equipment isn't cheap of coarse but if you're going to be handling thousands of pounds of rock, it's just too much to consider panning as an option for processing. Another possibility that needs to be considered is the use of mercury in capturing the finest gold particles from your ores.
