Top 7 Lithium Tailings Extraction Plant Suppliers in the United States

Headquartered in San Francisco, American LithiumTech Solutions has been a cornerstone of the U.S. lithium processing industry since 2008. What started as a small team of engineers with a passion for sustainable mining has grown into a national leader, especially when it comes to lithium tailing ore extraction equipment. Their approach? Combining cutting-edge dry process equipment with a focus on energy efficiency—something that's become a game-changer for mines in water-scarce regions like Nevada and Arizona.

One of their standout products is the LT-5000 Dry Separator, a compact system designed to sift through tailings and separate lithium-rich particles without relying on large amounts of water. "We worked with a mine outside Reno that was struggling with water restrictions," says Maria Gonzalez, the company's lead process engineer. "After installing our dry process equipment, they saw a 35% reduction in operational costs and could keep production going even during droughts." Clients also rave about their after-sales support, with many noting that the team provides on-site training and maintenance checks to ensure equipment runs smoothly for years.

Recent projects include a partnership with a major battery manufacturer to process tailings from an old silver mine in Idaho, turning what was once considered waste into a viable lithium source. With a growing focus on circular economy practices, it's no wonder they've become a go-to for companies looking to meet both production and sustainability goals.

Based in Portland, West Coast Recycling Equipment (WCRE) has built its reputation on two things: robust wet process equipment and industry-leading air pollution control system equipment. Founded in 2012, they recognized early on that while dry processing works for some tailings, others—especially those with high moisture content—require a different approach. Their wet separation systems, paired with advanced air filtration, have made them a top choice for mines in the Pacific Northwest, where rainfall is abundant and environmental regulations are strict.

Their flagship product, the HydraSep W-800, uses a combination of flotation and gravity separation to extract lithium from wet tailings. But what clients love most is the integrated air pollution control system that comes standard. "Mines in Washington and Oregon face tough emissions rules," explains Jason Park, WCRE's sales director. "Our systems capture over 99% of dust and volatile compounds, so operators don't have to worry about fines or community pushback." This focus on compliance has helped them secure contracts with state-run mining projects and private companies alike.

Another area where WCRE shines is scalability. Their equipment ranges from small-scale units processing 500 kg/hour to industrial systems handling 2,500 kg/hour, making them suitable for everything from artisanal mines to large operations. A recent project in British Columbia (though technically in Canada, their reach extends north) involved retrofitting an old copper mine's tailings pond with their wet process equipment, resulting in a 40% lithium recovery rate that the client called "beyond our expectations."

When it comes to full-service solutions, Midwest Industrial Extractors (MIE) in Chicago is hard to beat. Founded in 1995, they've expanded from general industrial equipment to become a leader in lithium tailings extraction, with a focus on providing not just the main processing machines but also the auxiliary equipment that keeps operations running seamlessly. Think conveyors, control panels, water treatment units, and even automated monitoring systems—everything a mine needs to turn tailings into usable lithium.

"We see ourselves as partners, not just suppliers," says CEO Thomas Carter. "A mine might have great extraction equipment, but if the auxiliary systems—like material handling or water recycling—aren't up to par, the whole operation suffers." Their "Turnkey Tailing Package" includes lithium tailing ore extraction equipment, a wet process or dry process system (depending on the site), and all the auxiliary equipment needed to connect it all. For example, a recent project in Michigan's Upper Peninsula included their MIE-3000 Extractor, a series of pneumatic conveyors, and a water treatment unit that recycled 90% of the process water, drastically reducing the mine's environmental footprint.

Clients also appreciate their focus on durability. Midwest winters are harsh, and MIE's equipment is built to withstand extreme temperatures and heavy use. "Our machines in Minnesota have been running 24/7 for three years with minimal downtime," notes a production manager at a lithium processing plant in Duluth. "The auxiliary equipment, like the hydraulic balers for waste material, has held up just as well as the main extractors."

Down in Houston, Southern States Processing Systems (SSPS) has carved out a niche with their innovative use of compact granulator with dry separator equipment. Founded in 2010, they specialize in equipment that's both high-capacity and space-efficient—perfect for mines where real estate is limited or retrofitting existing facilities is necessary.

Their CG-2000 Compact Granulator is a prime example. About the size of a shipping container, it combines granulation (breaking down tailings into uniform particles) and dry separation in one unit, eliminating the need for separate machines and saving valuable floor space. "We worked with a mine in Arkansas that was converting an old warehouse into a processing facility," says SSPS engineer Raj Patel. "Our compact system fit right in, and we were able to get them up and running in just six weeks—half the time of a traditional setup."

Another area where SSPS excels is energy efficiency. Their equipment uses variable-speed motors and smart sensors that adjust power usage based on tailings input, reducing electricity costs by up to 25%. For a mine processing 10,000 tons of tailings per month, that translates to savings of over $100,000 annually. It's no surprise, then, that they've become a favorite among mid-sized operations looking to maximize output without breaking the bank.

Northeast Green Tech (NGT) in Albany may be one of the newer players on this list (founded in 2015), but they've quickly made a name for themselves with their focus on cutting-edge materials science. Their secret weapon? Nano ceramic ball for ball mill equipment, which they've developed to improve the efficiency of grinding tailings into fine particles—a crucial step before separation.

Traditional ball mills use steel balls, which can wear down quickly and contaminate the tailings with iron particles. NGT's nano ceramic balls, however, are harder, lighter, and more durable. "We tested them against steel in our lab," explains Dr. James Wei, the company's R&D director. "The ceramic balls reduced grinding time by 20% and lasted three times longer, which means less downtime for ball replacement and purer tailings for lithium extraction." When paired with their dry separator systems, this technology has helped clients achieve lithium recovery rates of over 85%—well above the industry average of 70-75%.

NGT also prides itself on transparency. They provide clients with detailed data on particle size distribution, recovery rates, and energy usage, allowing mines to fine-tune their processes for optimal results. A recent project with a rare earth mine in Pennsylvania, which also produces lithium-rich tailings, saw a 15% increase in lithium yield after switching to NGT's ceramic ball mills and dry separators.

With a name that hints at their global reach, Pacific Rim Lithium Services (PRLS) in Seattle has built a reputation for equipment that can handle the toughest tailings—including those from overseas projects. Founded in 2003, they started by exporting U.S.-made equipment to mines in Canada and Australia, but in recent years, they've turned their focus back home, bringing that international expertise to U.S. lithium operations.

Their specialty? Wet process equipment designed for high-mud tailings, which are common in the Pacific Northwest and parts of Alaska. The PRLS MudMaster X7 uses a proprietary flocculation system to separate clay and silt from lithium particles, a process that's notoriously tricky with traditional equipment. "Mud can clog screens and slow down separation," says operations manager Kevin Chen. "Our system uses a combination of polymers and centrifugal force to 'clean' the tailings before they reach the separator, making the entire process faster and more efficient."

They're also leaders in air pollution control system equipment, with their EcoFilter 3000 series designed to capture fine dust and harmful emissions. "We recently worked with a mine in British Columbia that was expanding into the U.S. market," Chen adds. "They needed equipment that met both Canadian and U.S. emissions standards, and our EcoFilter was the only system that could do it without sacrificing performance."

What clients love most about PRLS is their flexibility. They offer both stationary and mobile units, the latter of which can be transported to remote sites via truck or barge. "We have a client in Alaska that's only accessible by boat in the summer," notes Chen. "Our mobile wet process units can be set up in days, allowing them to process tailings during the short mining season."

Rounding out our list is Rocky Mountain Extraction Innovators (RMEI) in Denver, a company that's all about rugged reliability. Founded in 1988, they've spent decades building equipment for the Rocky Mountain region's hard-rock mines, and that experience has translated perfectly to lithium tailings extraction. Their machines are designed to handle extreme temperatures, high altitudes, and the rough terrain that's common in states like Colorado, Wyoming, and Montana.

One of their most popular products is the RM-T10 Tailing Processor, a heavy-duty system that combines crushing, grinding, and separation into one unit. "We built this for mines at 8,000 feet or higher," says lead designer Mike Torres. "The motors are rated for high altitude, and the controls are housed in insulated, weatherproof enclosures to keep them safe from snow, rain, and dust." Clients in Wyoming's lithium belt have praised the RM-T10 for its ability to run continuously in sub-zero temperatures, a feat that many competitors' equipment can't match.

They also offer a range of auxiliary equipment, including hydraulic press machines for compacting waste material and conveyors designed to handle steep inclines. "A mine outside Aspen needed to move tailings up a 30-degree slope," Torres recalls. "Our custom-built hydraulic conveyors made that possible, reducing the need for expensive earthmoving to create flat terrain."
