Mayflower Mill - Silverton, Colorado - San Juan County Historical Society

The Mill recovered metals from the ore by gravity separation and by selective flotation. Sulfide ore minerals were concentrated by froth flotation, a method used in the early twentieth century that allowed processing of ores. The original mill equipment is still in working order. It is the only intact and functional mill of its kind in Colorado.
