Extraction of Gold

Extraction of Gold

The socalled quot brown gold quot is formed by the action of nitric acid on an alloy of gold and silver containing 20 per cent, of gold. The silver dissolves, leaving the gold as a brown, spongy sheet, reconverted at 1040176 C. into ordinary gold. The brown form β differs from ordinary α gold in density and magnetic properties.
