The Properties and Appliions of Platinum
Platinum metal has a number of useful properties, which explains its appliion in a wide range of industries. It is one of the densest metal elements—almost twice as dense as lead—and very stable, giving the metal excellent corrosion resistant properties. A good conductor of electricity, platinum is also malleable (able to be formed without breaking) and ductile (able to be deformed

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

The blast furnace is filled with iron ore, coke and limestone. A very hot blast of air is blown in, where it causes the coke to burn. The extreme heat makes the carbon react with iron ore, taking off the oxygen from iron oxides, and making carbon dioxide. The carbon dioxide is a gas and it leaves the mix. There is some sand in with the iron.
