Gold production in global mines has been declining except from China because it is foreseeable that gold mining will be exhausted. The increase in China’s gold production in recent years has only been temporary. As the current demand for gold on the market far exceeds the supply, the imbalance between supply and demand continues.
The most acidic liquid in the world, “Aqua regia”, can even dissolve gold!
The most acidic liquid in the world is the so-called aqua regia, also referred to as the “liquid that can dissolve most of the metals in the world.” Silver is the only substance that aqua regia cannot dissolve. However, aqua regia can be used in a variety of fields due to its capacity to dissolve metals other than silver.
The origin of “Aqua regia”
The history of Aqua regia is extensive. Abu Musa Jabir ibn Hayyan, an Arab Muslim scientist, created it in the year 800. It can be said that the development of aqua regia led to the later flourishing of alchemy in Europe. Aqua regia is still used today in many different fields. Wang Shuifu was hailed as an invention that would usher in a new era as soon as he appeared. We can also say that it can emphasize how exceptional the invention of aqua regia is because it uses a cutting-edge and modern technology.
The light of hope: gold recycling
Additionally, manufacturing uses gold. However, the gold that was used to adorn industrial products will also be thrown away once they are no longer needed. Under this cycle, it is conceivable that the market’s supply of gold will decline year after year. It can also be said that this is a challenging time for the manufacturing sector that uses gold as a raw material because the price of gold keeps rising. The aqua regia can now assist in lowering the price of gold.
Aqua regia can dissolve the gold used in industrial products (especially circuit boards) and then restore it, preventing the market’s supply of gold from steadily declining. The problematic issue of gold reduction is brought on by aqua regia’s recycling process, which
has transformed the waste into the hope of gold recycling supply.
“Urban Mine”
Industrial products have always had very fixed waste disposal sites as their final destination. These landfills are now sometimes referred to as urban mines. Urban mines are, as the name implies, mines that are abundant in different metal resources that can be recycled and used by people.
Urban mines are not impenetrable, though. Sorting gold and other metals is a labor-intensive and inefficient process, making it challenging to put into practice.
