About Platinum - Gold and silver mines

Irrespective of the chemical separation processes used, the platinum metals are recovered in a finely divided metallic powder form. They can be converted to massive metal form by electron-beam melting. The lower-melting-point metals palladium and platinum can be fused by induction melting techniques.
