Gold, silver and platinum are precious metals. These metals have low density, higher conductivity, are non-magnetic in nature. They hold a high economic value. Gold is a soft and yellow-coloured metal. It is found in its natural form called ‘nuggets’. Silver, a white-coloured soft metal, occurs in combination with sulphur, copper, lead or arsenic.
