PURE GOLD AND IRON FROM SAND - Elmer Gates

2006-12-20  marvelous method has been perfected by which unlimited quantities of the purest iron and gold can be extracted from sand. This means that immense tracts of what has always been believed to be worthless territory—such as the arid, sandy plains of the West—are, on account of this wonderful discovery, turned into a treasure-ground whose value can hardly be estimated. All sand does not contain gold or iron, except in inappreciable traces. The ordinary sand of Maryland or Virginia or Indiana does not. But throughout this country sands are found containing iron in inexhaustible quantities. You may find such sand, in many localities, without going farther afield than your own yard. By the invention which Professor Gates has perfected the gold and iron is easily separated from the sand
