At Sardis, alluvial gold mining dates to ~700 BC and gold is still produced today. However, owing to the small size of the gold at Sardis, it was necessary to use mercury to amalgamate the goldbearing sluice concentrates as part of a modern economic evaluation of this ancient gold occurrence (Topkaya, 1984) .

mercury is required to extract one gram of gold. However, tailings from this process are often repeatedly run through the ball mills. Each time more auriferous, or goldladen, mercury is produced. Though less mercury escapes by this method, this type of amalgamation is also a significant source of pollution and loss of gold. Read More
