FEATURE: Chinese pay price for world’s rare earths addiction

NOT WORTH IT:Some researchers say the income from the mining cannot make up for the environmental degradation, while farmers say they have lost their income

Farmer Wang Tao used to grow corn, potatoes and wheat within a stone’s throw of a dumping ground for rare earths waste until toxic chemicals leaked into the water supply and poisoned his land.

Farmers living near the 10km2 expanse in northern China say they have lost teeth and their hair has turned white while tests show the soil and water contain high levels of cancer-causing radioactive materials.

“We are victims. The tailings dam has contaminated us,” Wang, 60, said at his home near Baotou city in Inner Mongolia, home to the world’s largest deposits of rare earths, which are vital in making many high-tech products.

“In this place, if you eat the contaminated food or drink the contaminated water it will harm your body,” Wang said, pointing toward lifeless fields now strewn with rubbish around Dalahai village, a few hundred meters from the dump.

China produces more than 95 percent of the world’s rare earths — 17 elements used in the manufacture of products ranging from iPods to flat-screen televisions and electric cars.

Two-thirds of that is processed in mineral-rich Baotou on the edge of the Gobi desert.

Environmental groups have long criticized rare earths mining for spewing toxic chemicals and radioactive thorium and uranium into the air, water and soil, which can cause cancer and birth defects among residents and animals.

Beijing, keen to burnish its green credentials and tighten its grip over the highly sought-after metals, has started cleaning up the industry by closing illegal mines, setting tougher environmental standards and restricting exports.

However, Wang and the other farmers in Dalahai blame state-owned giant Baogang Group, China’s largest producer of rare earths and a major iron ore miner and steel producer, for poisoning their fields and ruining their livelihoods.

Strong winds whip across the millions of tonnes of waste at the dump, blowing toxic and radioactive materials toward local villages.

“It is the pollution from the tailings dam,” Wang Er, 52, said, pointing a dirty finger at his spiky hair that started turning white 30 years ago.

Baogang, which has rare earths and iron ore refineries stretching for about 7km along a road in the area, did not respond to reporter requests for comment.

However, a 2006 study by local environment authorities showed levels of thorium, a by-product of rare earths processing, in Dalahai’s soil were 36 times higher than other areas of Baotou, state media have reported.

“People are suffering severely,” the Chinese-language National Business Daily said in December, citing the official study.

Sixty-six villagers died of cancer between 1993 and 2005 while crop yields fell “substantially.”

“There is not one step of the rare earth mining process that is not disastrous to the environment,” Greenpeace China’s toxics campaign manager Jamie Choi (崔喜晶) said in a recent report.

Choi said the impact of the government crackdown depends on whether it is “implemented properly.”

The environmental damage caused by rare earths mining in China could be irreversible, according to Wang Guozhen (王國珍), a former vice president of the -government-linked China Nonferrous Engineering and Research Institute.

“The money we earned from selling rare earths is not enough to repair the environment ... definitely not enough,” Wang said.

As demand for rare earths soars, China is slashing export quotas. Analysts say Beijing wants to drive up global prices and preserve the metals for its own burgeoning high-tech industries.
