Top 5 most populous megacities worldwide
The United Nations has released fresh data on the most populous cities in the world. Let's take a look at the top megacities by population.
Gold
Gold ranks first on the list of the most profitable metals as it is traditionally considered a safe haven asset. During turbulent times, investors flee en masse to gold. All market participants have long known that gold helps to weather economic storms, although its price does not always show steady growth.
Silver
According to economists, silver is one of the leading precious metals. Sometimes, this metal can compete with gold. However, its price is still lower than the latter. Nevertheless, silver remains popular among investors. From time to time, the silver price rises sharply.
Platinum
Platinum holds third place in this rating. This precious metal is among the leaders due to its popularity among investors. Currently, this metal is widely used in the jewelry industry, radio engineering, computers, and aerospace industry. At the same time, platinum is essential for the automotive industry. For a long time, demand for platinum far exceeded supply, and the metal’s price was twice as much as gold. However, the prices stabilized later.
Lithium
The fourth most profitable metal is lithium. Lithium is also called the "white oil" as it is crucial for the modern global industry. Its consumption will continue to grow as the energy transition occurs. At present, most lithium goes to battery makers. It increases the strength of alloys in metallurgy. According to the estimates, 40% of lithium is used for batteries, 26% for ceramics and glass, 7% for metallurgy, 4% for air conditioning, and 3% for medicine.
Aluminum
Aluminum rounds out the top 5 most popular precious metals. It is the most common metal on Earth, accounting for 8% of the weight of the planet's crust. Even the human body contains it. However, aluminum is rarely found in its pure form. That said, the process of obtaining aluminum is much more complicated than most metals. The properties of aluminum are lightness and ductility, resistance to corrosion, and high electrical and thermal conductivity. It is used in the aerospace industry, automobile, ship, aircraft, building construction, and electronics.
