Final yr, scientists introduced the invention of two new minerals: elaliite and elkinstantonite. These have been fascinating finds, maybe much more so as a result of they got here from a 15-ton meteorite that had hurtled by means of house to crash down in Somalia.
Whereas there are presently almost 6,000 mineral species acknowledged by the International Mineralogical Association, Robert Hazen, a mineralogist on the Carnegie Institution’s Geophysical Laboratory and George Mason College, says there are an estimated 9,000 to 10,000 minerals that exist proper right here on our personal planet.
“Most of these minerals are going to be extraordinarily uncommon, they’re going to be tiny,” he says. “But every of them tells us one thing concerning the previous, about how planets work, about the place life got here from and who we’re.”
Seaborgite, for instance — a brand new mineral species introduced in 2021 that claimed the title of “mineral of the year” — was present in Utah. It’s “clear with vitreous luster and really pale-yellow streak,” exhibiting “shiny lime-green fluorescence” underneath a laser, in response to the researchers who first described it.
An Invaluable Commodity
As a result of they are often discovered throughout us, people have lengthy trusted minerals for a complete number of makes use of.
They presently make up vital components of the tech we rely on, for instance, together with the screen you’re utilizing to learn this. Our personal our bodies need them to stay healthy. We additionally covet valuable minerals merely for his or her magnificence or as objects of examine.
Cobalt and lithium are essential parts of rechargeable batteries, for instance. Phosphorus, derived from phosphate rock, is a fertilizer that fuels agriculture the world over, whereas copper finds its manner into any number of electronics as a result of its conductivity. And for those who’re rummaging round in your pocket for cash, there’s an excellent likelihood you’ll select one containing nickel.

“I go searching my workplace and I see all of the various things — it is exhausting to determine a single factor that is not derived, in a technique or one other, from minerals,” Hazen says. If minerals have been to go, he continues, “your world would simply vanish.”
Human Affect
As a lot as minerals have formed us as a species, nevertheless, people are additionally shaping minerals.
Hazen was a part of a group that identified a group of minerals that happen “principally or completely as a consequence of human processes.” There are over 200 of those such mineral species to date.
However our dependence on minerals comes with social and environmental prices. The mining of many of those minerals is wrapped up in points comparable to baby labor, abuses of staff’ rights, and the degradation and lack of pure ecosystems. The cobalt that drives our tech is simply one example.
New frontiers of mineral availability — such because the ocean ground — provide different alternatives, but in addition include nice, presumably unexpected dangers of their very own, say scientists. A spike in demand plus the crunch on availability of minerals important to the transition to “inexperienced” applied sciences comparable to electric cars, wind generators and photo voltaic panels however makes this prospect enticing for some.

Considering Twice
Amid hovering demand, there are warnings of lithium shortages, for instance. Merely put, there may be not an infinite variety of lithium-rich deposits ultimate for mining around the globe … however that doesn’t imply we’re going to expire, says Hazen.
“We will mine them out and run out of lithium in that sense, however each cubic foot of seawater has lithium in it,” he says. “It simply prices more cash and extra effort.” Estimates state that round 180 billion tons of lithium are discovered within the oceans.
Typically, nevertheless, Hazen is of the view that the impulse to seize minerals wherever they exist must be approached with “excessive care and warning,” given the potential penalties.
“The minerals aren’t going wherever,” he says. “They’ve been there for tens to perhaps tons of of 1000’s of years and, presumably, they’ll nonetheless be there hundreds of thousands of years sooner or later until we determine to use them.”
