Lavoisier succeeded in melting platinum using oxygen to enhance the heat of the furnace but it would still be many years before a process could be found to produce commercial quantities. Of course, that was prior to Lavoisier's beheading at the height of the French Revolution in 1794.
Platinum catalysts are used in the contact process for producing sulfuric acid, in the Ostwald process for the production of nitric acid, and in petroleum cracking, as well as in a variety of other reactions. Platinum is also used as a catalyst in fuel cells and in catalytic converters for automobiles.
Platinum is rarely found on its own, but in combination with other base and precious metals. Extraction of the pure metal from ores is a complex process, and includes milling the ore, a froth ...
The Platinum Process. To the eye accustomed to the punch of a silver gelatin print, a platinum print will often feel "softer" or lower in contrast. In reality there are actually more steps between pure black and pure white in platinum prints than in a silver gelatin print. This contributes to the deeper, richer feeling you experience when looking at these prints.

Fabrication of Platinum Alloy Ingots. Any small chips of gold alloys imbedded in the platinum alloys during the rolling process will be melted into the platinum during the annealing which is above the melting point of most gold alloys. Platinum alloys have a tendency to smear or build up on the rolls in rolling mills.
