Why is gold a renewable resource?
Gold is not a renewable resource. When we have mined all the existing gold from the Earth, there will be no more gold.
Non-renewable resources are environmental resources that cannot be replenished. Once they have been used up, there will be no more. Most non-renewable resources are minerals, which are mined, for example, gold, iron ore, titanium. Coal and oil are known as fossil fuels and are also non-renewable.
Metallic resources are things like Gold, Silver, Tin, Copper, Lead, Zinc, Iron, Nickel, Chromium, and Aluminum.
Gold is in hot demand as an investment, a status symbol, and a key component in many electronic products. But it's also a finite resource, and there will eventually come a stage when there is none left to be mined.
Diamonds are non-renewable resources. Non-renewable resources are those that cannot be easily replenished or replaced. Diamonds take a long time to develop naturally.
Gold is the chemical element with 79 protons in each atomic nucleus. Every atom containing 79 protons is a gold atom, and all gold atoms behave the same chemically. In principle, we can therefore create gold by simply assembling 79 protons (and enough neutrons to make the nucleus stable).
Renewable energy share of end-use:
The metals for which renewable energy is a significant share of end-use are cobalt, lithium, rare earths and tellurium.
Metals are not a renewable resource. They are found in rock, called ore, which is a part of the earth's crust. There is a finite amount of metal in the earth, and there is a financial and environmental cost to mining and refining it into a usable product.
Gold is mineral but petroleum,and coal are fossil fuels.
Since the planet has a finite supply of gold, running out of the natural resource is conceivable. According to US Geological Survey estimates, there is only about 52,000 tons of mineable gold still in the ground.
Can gold be recycled?
Fortunately, gold can be recycled over and over and still be just as good as it was the day it was mined. So, recycled gold is a sustainable commodity, as it never decreases in value. By reusing gold, the environment can be protected from additional harm.
The United States holds the largest stockpile of gold reserves in the world by a considerable margin at over 8,100 tons. The U.S. government has almost as many reserves as the next three largest gold-holding countries combined (Germany, Italy, and France).
About 244,000 metric tons of gold has been discovered to date (187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons). Most of that gold has come from just three countries: China, Australia, and South Africa.
With gold having been in use since the dawn of history and new mining still occurring, it may seem strange to think of a day when there is no more gold to be extracted from the ground. Nevertheless, like any other limited natural resource, there is a finite supply of gold in the world.
Gold is heavenly, in every sense of the word. Most people don't know this but, while we mine for gold here on earth, all of the gold that's deposited in our planet was formed during the explosions of stars and collisions of asteroids, and eventually found its way to earth over time.
Salt is considered a non-renewable natural resource because the time it takes natural processes to create more salt is longer than the time it takes for people to use it up.
Sunlight is a renewable resource, and its most direct use is achieved by capturing the sun's energy. A variety of solar energy technologies are used to convert the sun's energy and light into heat: illumination, hot water, electricity and (paradoxically) cooling systems for businesses and industry.
Why do people call water a "renewable" resource? Water may be considered an inexhaustible resource because the total supply of water in the biosphere is not affected by human activities. Water is not destroyed by human uses, although it may be held for a time in combination with other chemicals.
Gold does not react with most chemicals but is attacked by chlorine, fluorine, aqua regia and cyanide and dissolves in mercury. In particular, gold is insoluble in nitric acid, which will dissolve most other metals.
Gold is rare throughout the Universe because it's a relatively hefty atom, consisting of 79 protons and 118 neutrons. That makes it hard to produce, even in the incredible heat and pressure of the 'chemical forges' of supernovae, the deaths of giant stars responsible for creating most chemical elements.
What color makes gold?
What Two Colors Make Gold? Making gold paint is actually very simple. All you need is a warm shade of yellow and a light, warm shade of brown paint. For that extra sparkle, you can add a touch of gold glitter powder to your paint mixture.
Solar panel companies prefer lithium-ion batteries because they can store more energy, hold that energy longer than other batteries, and have a higher Depth of Discharge. Also known as DoD, Depth of Discharge is the percentage to which a battery can be used, related to its total capacity.
Titanium – metal of the future.
Wood is considered humankind's very first source of energy. Today it is still the most important single source of renewable energy providing about 6 percent of the global total primary energy supply.
Are We Going to Run Out of Copper? It Is Highly Improbable! Since 1960, there has always been, on average, 38 years of reserves, and significantly greater amounts of known resources (USGS data). In addition, recycling, innovation and mining exploration continue to contribute to the long-term availability of copper.
There have been some estimates that we might run out of iron ore by 2070, but, this is one estimate only. Whether or not we run out of iron ore depends on a range of variables, which we list in the guide below.
No, steel is not a renewable resource. Steel can only be made from iron, which must be mined from the ground in order to be useful.
We haven't found a good substitute for oil, in terms of its availability and fitness for purpose. Although the supply is finite, oil is plentiful and the technology to extract it continues to improve, making it ever-more economic to produce and use. The same is also largely true for natural gas.
In the past, black gold was the nickname for oil, especially as people who found it trickling out of the ground made a small fortune — akin to finding gold. Now black gold is the term that defines blackened gold. Black gold looks edgy and stylish, giving jewelry a fresh and modern look that yellow gold can't provide.
According to the MAHB, the world's oil reserves will run out by 2052, natural gas by 2060 and coal by 2090.
Is there gold on the moon?
The moon isn't so barren after all. A 2009 NASA mission—in which a rocket slammed into the moon and a second spacecraft studied the blast—revealed that the lunar surface contains an array of compounds, including gold, silver, and mercury, according to PBS.
Chrysopoeia, the artificial production of gold, is the symbolic goal of alchemy. Such transmutation is possible in particle accelerators or nuclear reactors, although the production cost is currently many times the market price of gold.
One study found there is only about one gram of gold for every 100 million metric tons of ocean water in the Atlantic and north Pacific. There is also (undissolved) gold in/on the seafloor. The ocean, however, is deep, meaning that gold deposits are a mile or two underwater.
Gold is the most non-reactive of all metals and does not rust. Gold is so pliable that it can be made into sewing thread. Gold can conduct heat and electricity. Apart from copper and caesium, Gold is the only non-white coloured metal.
Recycled gold is gold that is previously part of another piece of jewelry and it's been melted down and refined, and cast again and made into a new piece of jewelry. The good thing about gold is that it can be infinitely recycled, it can be melted down millions of times and never lose its integrity.

Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides. The white color of quartz makes it easy to spot in many environments.
There is no specific depth at which gold can be found. Examples of this are the Welcome Stranger – the largest gold nugget ever found – which was retrieved at only 3cm (1.18in) below the surface. Oppositely, gold mining operations today take place at a depth of around 3km (1.8 miles) under the Earth's surface.
Soils Associated with Gold Deposits. By far, the best-known type of soil which may indicate the presence of gold is known as “black sand.” Black sands are certainly not proof of the existence of nearby gold, only that the soil has a lot of minerals and heavy metals, one of which is gold.
It can typically take between 10 and 20 years after a deposit is discovered before a gold mine is ready to produce material that can be refined into bullion. Discover the key stages in the life cycle of a mine below.
Why is gold so expensive?
Gold's value is ultimately a social construction: it is valuable because we all agree it has been and will be in the future. Still, gold's lustrous and metallic qualities, its relative scarcity, and the difficulty of extraction have only added to the perception of gold as a valuable commodity.
Satellite imaging has shown that the top 10 centimetres of regolith (moon soil) at the south pole of the moon appear to hold about 100 times more gold than the richest mines on earth. Only a few years ago, most geologists would have laughed at the idea of mining anything from our moon.
We do know that gold makes up about four parts per billion of the earth's crust. What we don't know, however, is precisely how much gold is still out there. The WGC estimates that there are 54,000 tonnes of “below-ground gold reserves” waiting to be mined.
The fact that active volcanoes produce gold is not that surprising, Dr. Noble said. Significant quantities of gold are also being found along mid-ocean ridges, where so-called "black smokers" emit magma from beneath the ocean floor. Such spots are loaded with minerals, he said.
The Extraterrestrial Element
Unlike other metals that form in the Earth's crust, gold comes from space. Stars are made mostly of helium and hydrogen, which provide light. Inside the star's core, nuclear fusion churns out energy.
While nuclear fusion within the Sun makes many elements, the Sun cannot synthesize gold. The considerable energy required to make gold only occurs when stars explode in a supernova or when neutron stars collide. Under these extreme conditions, heavy elements form via the rapid neutron-capture process or r-process.
On earth, gold is one of the most valuable precious metals and rarest natural minerals. It is also one of the 118 elements so far discovered and classified by humans.
Scientists at Hokkaido University in Japan have developed a photoelectrode that uses gold to convert far more sunlight to energy than is currently possible.
Gold is mineral but petroleum,and coal are fossil fuels.
Theoretically, it's possible to form gold by the nuclear processes of fusion, fission, and radioactive decay. It's easiest for scientists to transmute gold by bombarding the heavier element mercury and producing gold via decay. Gold cannot be produced via chemistry or alchemy.
How much gold is left in the Earth?
About 244,000 metric tons of gold has been discovered to date (187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons). Most of that gold has come from just three countries: China, Australia, and South Africa.
Rare Combinations. Almost all gold mined on Earth is native gold; that is, the gold is in a pure or nearly pure state. Unlike copper, silver, iron and other metals, gold rarely combines with other nonmetallic elements to form complex minerals. It is this quality that also makes it resist corrosion.
Since the planet has a finite supply of gold, running out of the natural resource is conceivable. According to US Geological Survey estimates, there is only about 52,000 tons of mineable gold still in the ground.
An adult human body weighing 70 kg contains about 0.2 milligrams of gold. It's been found that the element plays an important health function, helping to maintain our joints, as well as facilitating the transmittal of electrical signals throughout the body.
In studying the different uses of gold in the healing arts, we find that for thousands of years acupuncturists used silver and gold needles. It was said that gold is warm and stimulating while silver contains a cold, inhibiting factor.
Gold has several qualities that have made it exceptionally valuable throughout history. It is attractive in colour and brightness, durable to the point of virtual indestructibility, highly malleable, and usually found in nature in a comparatively pure form.
We haven't found a good substitute for oil, in terms of its availability and fitness for purpose. Although the supply is finite, oil is plentiful and the technology to extract it continues to improve, making it ever-more economic to produce and use. The same is also largely true for natural gas.
