The ten-kilometer-thick stratum on the earth’s surface contains six thousandths of titanium, which is 61 times more than copper, and ranks tenth in the crust (ranking elements in the crust: oxygen, silicon, aluminum, iron, calcium, sodium, Potassium, magnesium, hydrogen, titanium), just grab a handful of soil from the ground, which contains a few thousandths of titanium. Titanium ore with reserves of more than 10 million tons in the world is not rare.
There are hundreds of millions of tons of sand and gravel on the earth. Titanium and zirconium, two minerals heavier than sand and gravel, are mixed in the gravel. After the seawater has been washed day and night for millions of years, the heavier ilmenite Crushing with the zircon placer, on the long coast, a piece of titanium ore layer and zirconium ore layer are formed. This mineral layer is a black sand, usually a few centimeters to tens of centimeters thick. Titanium is not ferromagnetic, and nuclear submarines built with High Purity Titanium do not have to worry about attacks by magnetic mines.
