The technique of gold recovery from golden sands is known since ancient times, described by Plutarh, Strabon, Plinius and Diodor from Sicily. For this purpose, buddle ("saitroc"), woven sieves and burned clay boards were used. These boards were rounded, with a very good drainage opening, having on the inner bottom and on the side walls some ...
