Platinum Mining | Processing Equipment | Flow Chart

Platinum (element #78, symbol Pt) is a dense, silvery-gray metal. The platinum group of elements consists of metals with similar physical properties as platinum and these elements are among the rarest in the Earth's crust. They have high melting points, are dense or heavy and are non-reactive with other elements.
