The United States has been mining aluminum ore since the mid-1800s.
At one point, the US had an estimated 12 million tons.
That’s less than half the amount of aluminum mined by China today, which is about 50 times more.
That made the prospect of mining aluminum all the more enticing.
But in the mid 2000s, there was a serious slowdown in the mining industry, and there was an increase in demand for aluminum from the mining community.
That led to a boom in aluminum mining in Australia.
But a big problem for aluminum is that it has a very high density, meaning it is more dense than other metals.
That means it has to be heated to more than a million degrees Celsius.
In other words, it takes more energy to melt a pound of aluminum than a pound that’s just a pound lighter.
That was a problem for the aluminum industry in the United States, which was hit hard by the recession of 2008-2009.
The aluminum industry lost millions of jobs.
Aluminum prices dropped dramatically.
So the aluminum miners, the producers of the metal, began looking for ways to diversify their business model.
One way they tried was by selling off their mining operations.
That was a huge boon for the miners, but the price of aluminum had to come down to keep up with demand.
So, aluminum miners started selling off mines.
In order to do that, the aluminum companies had to find new ways to increase the price, which has led to the current situation in the US.
Aluminum prices have dropped to a near-record low of about $2 per pound today, but there are a number of reasons why they have fallen.
The primary reason is the price recovery has been so slow.
It has taken more than two years for prices to recover to pre-2008 levels.
In fact, the last time prices were this low was in 2013, which made it seem as if the recovery was slowing.
So there was more pressure on aluminum prices to be lower.
The other major factor that is affecting the price is a new technology called “sulfur hexafluoride.”
This is a highly efficient way to convert carbon dioxide into sulfuric acid.
It is very much in demand in the world of biofuels.
The cost of sulfur hexaflouride is around $60 per ton.
That makes it very attractive for aluminum miners.
The other major reason that the aluminum prices have been so low is that there has been a decline in production.
The US had about a million tons per year of aluminum mining equipment at the time of the mining boom.
There was a major reduction in that production in recent years.
It’s now about a thousand tons per month.
So what’s the answer?
What does aluminum mining have to do with the global economy?
The answer is that the supply of aluminum is very important.
The world economy is based on the supply and demand of aluminum.
The demand is high, the supply is low.
The world’s aluminum demand is a function of two things: the supply to the United Kingdom and the demand to the rest of the world.
The United Kingdom has the world’s largest amount of iron ore deposits, and it’s very important to the economy.
It generates about 20 percent of the global economic output.
Iron ore is a very strong commodity.
It provides a lot of value to the global financial system, so it is an important element of the economy for the United Kingdoms.
The demand for iron ore is extremely important because the world needs iron ore for a variety of things.
It also provides a very large percentage of the fuel used by automobiles, as well as other large-scale industrial processes.
So when iron ore production is very low, there is a lot more demand for the commodity.
So, when aluminum prices were high, demand for steel ore in the global supply chain was also high.
The global supply of steel ore is about $5 trillion per year.
That is almost 40 percent of total global steel production.
So that’s a very important source of steel for the steel industry.
In the same way, aluminum demand has been very high.
It drives the world economy, and aluminum is a major contributor to that.
So how can aluminum prices rebound?
The U.S. government has been selling off large portions of its aluminum mining operations, and the aluminum producers have been selling their mines to other buyers.
The result has been that the prices of aluminum are down in both the United State and the world at large.
That’s not to say that the price doesn’t have to rebound.
There are still a number issues that need to be resolved.
The price of iron will have to rise to meet the demand for it.
The amount of sulfur used to extract the ore will have a huge impact on the price.
And the price will have
