The Properties and Applications of Platinum

Although studied by a number of English, French and Spanish chemists in the mid18th century, Francois Chabaneau was the first to produce a pure sample of platinum metal in 1783. In 1801, Englishman William Wollaston discovered a method for effectively extracting the metal from ore, which is very similar to the process used today.
