When Lakes Become a Soup of Minerals: the Fate of Great Salt Lake

Leave a reply

In the summer 2024, a California startup plans to start construction on a project to suck up water from the Great Salt Lake, Utah, United States to extract one of its many valuable minerals: lithium, a critical ingredient in the rechargeable batteries used in electric vehicles. The water will then be reinjected back into the lake, which Lilac Solutions says addresses concerns about the damaging effects of mineral extraction. At its peak, Lilac says it will use a series of pipes to suck up 80,000 gallons of water a minute to harvest the mineral. The company plans to eventually produce up to 20,000 tons of battery-grade lithium a year.

The effort is one of dozens of projects across the U.S. racing to build up a domestic supply of lithium and other battery minerals as the Biden administration is dedicating billions of dollars to strengthening the U.S. battery supply chain and reducing reliance on China, which dominates the global production of battery minerals.

One common extraction method of lithium pumps briny underground water into vast man-made ponds, where evaporation separates lithium from other elements over 18 months or more. Mining companies in Chile and elsewhere have used the approach, which drains scarce water resources and can leave deposits of toxic residues.

Lilac says its technology is much faster, taking a matter of hours from the time of extraction, while preserving water levels. Its method deploys reusable ceramic “beads” that attach to lithium atoms to separate them from the brine.

At the Great Salt Lake, mineral extraction is nothing new. The lake has been shrinking for decades because of agricultural, industrial and other diversions of its feed waters. Extraction of minerals accounts for about 13% of its water diversion, according to a 2019 study. Meanwhile, the lake has become a concentrated soup of minerals, since it doesn’t have an outlet that lets it discharge the ones that flow into it.

Global Nuclear Waste Movements: from Estonia to Utah

Leave a reply

Regulators are weighing whether a local uranium company can import the material for processing at a mill near the border of a Native American reservation. For Energy Fuels Inc , the shipment represents an economic lifeline, after the company posted an operating loss of $7.8 million for the first quarter of 2020. Its president in March 2020 described the U.S. uranium industry as being “on the cusp of complete collapse.”
But for the Ute Mountain Ute Tribe living near the facility – the only operational uranium mill in the United States – the proposal has stoked fears that tribal land will become a dumping ground for global radioactive waste. Both the White Mesa mill and the tribal reservation are in San Juan County, Utah’s poorest.

The mill, built in 1979, was only meant to process conventional uranium ores from the Colorado Plateau for up to 20 years, the tribe says. The Navajo Utah Commission and Navajo Nation have also that the company’s application be rejected. “The state of Utah must recognize and acknowledge the reality that the mill is far past its design life and no longer a conventional uranium mill, but, instead, a radioactive waste dump seeking to operate for decades, if not a millennium,” the Ute Mountain Ute Tribe said in a document submitted to the state….

The 660 tons of powdered material in question, now sitting in 2,000 drums at a plant on the Estonian coast near the Russian border, would be Energy Fuels’ first-ever radioactive import from outside North America. The powder is a byproduct from tantalum and niobium mining by Estonian company Silmet, which contains uranium. But it cannot stay within Estonia, where there is no licensed facility for reprocessing radioactive material. Energy Fuels says there is enough uranium in that byproduct that it is worth processing. Opponents say Energy Fuels is simply taking in waste, which would be stored on site. According to Energy Fuels business from the shipment would help the company keep its 70 workers employed.

Energy Fuels anticipates demand for domestic uranium could rise, after the Trump administration in April 2020 proposed a $1.5 billion federal uranium reserve that would purchase uranium from domestic producers. Such a reserve, however, would need Congressional approval – a major hurdle. The reserve was one of the main proposals to come from a federal Nuclear Fuel Working Group aimed at reviving the U.S. uranium and nuclear industry. The United States currently imports over 90% of its uranium from abroad for its reactors.

Salt Lakes of the World

Utah Great Salt Lake has shrunk to a depth of about 14 feet—nearly half its former average since it was settled by the Mormons 170 years ago. Under a controversial engineering plan, the lake would recede even further….State engineers want to siphon off some of the river water that flows into the lake and use it for the Salt Lake City area’s booming population. Proponents say the plan, which calls for lapping up a fifth of Bear River’s current unused flow, is essential for meeting the region’s needs.

But critics note that the diversion would cause the lake to drop by almost a foot, according to state estimates, eventually exposing 30 square miles of lake bed and potentially worsening the dust storms that regularly blanket the region and ruining a fragile wetlands habitat.

The debate echoes concerns heard in many other arid parts of the world. Salt lake ecology is especially delicate and requires a certain amount of fresh water to maintain a saline balance. Brine shrimp, for instance, could die off if the water becomes too salty.

In the Middle East, diversion of the Jordan and other rivers that feed the Dead Sea has shriveled the famous body of saltwater and its once robust tourism. The Aral Sea between Kazakhstan and Uzbekistan has shrunk to about 10% of its original size after diversions.

Critics, including environmental groups and affected businesses, say that under the new diversion plan lake-dependent businesses such as brine shrimp fishing would suffer, as would farmers whose land could be inundated upstream if existing dams are raised to retain more water. In all, the lake accounts for an estimated $1.3 billion in annual economic output, according to Utah State University, much of it from the shrimping industry, as well as mineral extraction and tourism.

The plan would also destroy wetlands along the lake shoreline that provide food and habitat for an estimated eight million birds, said Zach Frankel, executive director of Utah Rivers Council, an environmental group opposed to the project.

But proponents say the diversion of up to 72 billion gallons of water—enough to meet the needs of a city of one million for a year—is needed to forestall anticipated shortages for one of the fastest-growing regions in the country….“If Utah continues to grow, it’s not a matter of if but when we are going to need more water,” said state Sen. Stuart Adams, the Republican majority whip, who sponsored a bill to begin funding the estimated $1.5 billion project.
