Are precious metals on the cusp of a major rise in price?
Precious Metals Review
by Ron Hall
Gold, silver, platinum and palladium are probably the most recognized of the
group of metals referred to as precious although there are four others that fall
into this classification namely ruthenium, rhodium, iridium and osmium that
together with platinum and palladium are collectively known as the platinum
group metals.
Often referred to as noble metals – meaning that they resist attack by acids
and other reagents and do not corrode easily (although silver does tarnish) –
the precious metals tend to be attractive, durable, malleable and ductile.
