The Story of Stuff - Annie Leonard [30]
If I wanted to examine every kind of metal and mineral that gets extracted to make our Stuff, it would take several books’ worth of stories. So let’s look at a select handful of rocks that get dug up or blasted out of the ground. They’re pretty representative of the way all the metals and minerals needed for our Stuff are extracted.
Gold and Diamonds
Gold is used for a lot of things, from dentistry to glassblowing to stockpiling wealth. Gold is also used in electronics; virtually every modern electronic device—cell phones, laptops, televisions, GPS systems, MP3 players—has a bit of gold in it. But the biggest use, dwarfing all the rest, is jewelry. Jewelry accounts for more than 75 percent of the total amount of gold consumed today.82
Maybe you have a piece of gold jewelry that’s very dear to you. You’re not alone. I don’t have much of it, but I do have one little gold ring, given to me by a long-ago love.
When he wanted to buy me a ring, I insisted on an old one and a small one. I’d seen gold mines in South Africa. I knew that gold mining is horribly polluting, is routinely linked to human rights violations, and that more than three-quarters of the gold mined around the world ends up in jewelry. Since there is a lot of gold in jewelry rattling around in old ladies’ dresser drawers and increasingly in piles of e-waste, why fuel the market for mining more? So he got me an antique ring from the Tiny Jewel Box store in Washington, D.C. It’s inscribed “16 Mai 1896” and has a fleck of sapphire surrounded by tiny pearls not much larger than pencil dots.
I love that my ring has a past from long before me. Given the spelling of “May,” it was likely presented to someone in France or Germany. And given its tiny size, it seems unlikely to have been an engagement ring: perhaps a sweet-sixteen ring? I’ve often gazed at it and imagined its life on the finger of a young European woman and wondered who gave it to her. And of course the metal had a life before her, before being shaped into a ring.
Where was the gold for my sweet little ring mined? Maybe South Africa? For years, South Africa has supplied much of the world’s gold and still provides more than a quarter of today’s demand. When I visited South Africa in the mid-1990s, I looked out the window of the car in which I was riding and wondered aloud what geologic processes could have created so many randomly spaced small hills that covered the countryside. “Those aren’t hills,” my South African host explained. “Those are piles of mining waste.”
Mining enough gold for an average gold wedding ring creates about 20 tons of hazardous mining waste,83 which is sometimes dumped in rivers or the sea, sometimes just left right where it was created, as I saw in South Africa. The reason it’s toxic is that to get the gold from the ore, mining companies use a process called heap leaching, which means piling up the gold-containing ore and pouring cyanide over it to let it slowly drip through, extracting the gold on its way. At the same time, the cyanide also extracts toxic metals, including cadmium, lead, and mercury. The cyanide and toxic metal liquid runoff ends up in a big pool, from which the gold is extracted, leaving behind a heavy metal and cyanide contaminated pond next to a heavy metal and cyanide contaminated hill of leftover ore. Cyanide, I probably don’t need to remind you, is a deadly poison. An amount about the size of a grain of rice is enough to off a human being, and one-millionth of a gram of it in a liter of water kills fish,84 which is a big problem since much mine waste ends up in rivers
