Ulloa and Juan found mines with the whitish metal nuggets and took them home to Spain. While platinum-based fuel cells have been commercialized, they are dwarfed in current market share to new technologies like hybrids and electric vehicles (EVs) that have hit the markets in recent years. The manufacturing of specialty silicones may require platinum for highly durable, waterproof, and electrically insulating materials. Another large alluvial deposit is in the Ural Mountains, Russia, and it is still mined. Platinum fuel cells are also used to generate backup power for buildings. This led him to believe he was working with a single metal, but in truth the ore still contained the yet-undiscovered platinum-group metals.

[52] From their first encounters with platinum, the Spanish generally saw the metal as a kind of impurity in gold, and it was treated as such. Scheffer described platinum as being less pliable than gold, but with similar resistance to corrosion. Its long mane juts away from its head, and its face is gray, with green eyes and red pupils, and a green circular pattern below its eyes. It is estimated that about 1/5th of every manufactured product we use today, either contains platinum or requires platinum in some portion of its manufacturing. Due to platinum’s high melt value (3,215°F / 1,768°C), this rare white-colored precious metal is something of a relative newcomer to financial markets (compared to silver or gold). Unfortunately our Platinum Optimum bank account is only available to Standard Bank Group Private Banking clients. [73], During periods of sustained economic stability and growth, the price of platinum tends to be as much as twice the price of gold, whereas during periods of economic uncertainty,[74] the price of platinum tends to decrease due to reduced industrial demand, falling below the price of gold. Alloying this impure platinum residue called "plyoxen" with gold was the only solution at the time to obtain a pliable compound, but nowadays, very pure platinum is available and extremely long wires can be drawn from pure platinum, very easily, due to its crystalline structure, which is similar to that of many soft metals. [32] Platinum also strongly catalyzes the decomposition of hydrogen peroxide into water and oxygen[64] and it is used in fuel cells[65] as a catalyst for the reduction of oxygen. Finally, platinum is resistant to hydrochloric and sulfuric acids, whereas other substances are readily attacked by them. Thank your for your interest in our Standard Bank International solutions.

PtO2, also known as Adams' catalyst, is used as a hydrogenation catalyst, specifically for vegetable oils. 350Pd. [58], If pure platinum is found in placer deposits or other ores, it is isolated from them by various methods of subtracting impurities. Consequently, platinum is often found chemically uncombined as native platinum. [51], In 1735, Antonio de Ulloa and Jorge Juan y Santacilia saw Native Americans mining platinum while the Spaniards were travelling through Colombia and Peru for eight years.
