Founded in 2010, GreenMining Solutions Africa has grown from a niche equipment distributor to a full-service provider of lithium tailings processing systems. What really sets them apart? They don't just sell machines—they design custom solutions tailored to South Africa's unique geological conditions. "We've worked on everything from old tin mine tailings in Mpumalanga to lithium-rich residues in the Northern Cape," says Johannes Kruger, their lead engineer. "Each site has different challenges, so a one-size-fits-all approach never works."
Core Equipment: Their flagship lithium tailing ore extraction equipment is built around a modular dry process system. It starts with a high-efficiency crusher to break down coarse tailings, followed by a spiral separator that uses gravity to separate lithium minerals from waste. What's innovative here is their use of nano ceramic ball for ball mill equipment in the grinding stage. These tiny ceramic balls reduce friction by 30% compared to traditional steel balls, meaning less energy use and lower maintenance costs. "Our clients report saving up to 20% on electricity bills after switching to these balls," Kruger adds.
Local presence is another big plus. With offices in Johannesburg and Cape Town, GreenMining offers 24/7 technical support—a lifesaver for mines in remote areas. Their recent project with a lithium mine in Brits, North West Province, is a case in point: they installed a 300-ton-per-day tailings plant that boosted lithium recovery rates from 12% to 28% in just three months. "The mine was about to shut down its tailings operations," Kruger recalls. "Now they're turning a waste product into a revenue stream."
If there's one word to describe LithiumTech Innovations, it's "innovation." This Cape Town-based startup, founded in 2018, has quickly made a name for itself by blending cutting-edge tech with a focus on sustainability. "We started because we saw a gap: most tailings equipment was designed for other minerals, not lithium," explains CEO Zanele Mbeki. "Lithium particles are finer, more delicate—you need equipment that can handle that without losing valuable material."
Their star product? The Compact Granulator with Dry Separator , a compact system designed for small to medium mines. Unlike bulkier plants, this unit fits into shipping containers, making it easy to transport to remote sites. It uses a combination of air classification and electrostatic separation to isolate lithium, and it's surprisingly efficient: processing up to 100 tons of tailings per day while using 40% less water than traditional wet processes. "Water scarcity is a huge issue in South Africa," Mbeki notes. "Our dry process equipment cuts down on water use entirely, which is a game-changer for mines in the Karoo or Limpopo."
LithiumTech also stands out for its focus on hydraulic briquetter equipment . Once lithium is extracted, the leftover waste (called "gangue") is often powdery and hard to dispose of. Their hydraulic briquetters compress this waste into dense blocks that can be safely stored or even repurposed for construction. "It's not just about extraction—it's about closing the loop," Mbeki says. Their recent partnership with a community-owned mine in Lesotho (just outside the South African border) has been a success story: the mine now recovers 220 kg of lithium per day from tailings and sells the briquetted waste to local brick manufacturers. Talk about a win-win.
AMRS has been a heavyweight in South Africa's mining equipment scene since 1995, but they've recently pivoted hard into lithium tailings—and it's paying off. With a factory in Durban where they manufacture 80% of their equipment locally, they're able to keep costs low and delivery times short. "We don't import pre-built machines," says operations director Piet van der Merwe. "We source steel from Newcastle, motors from Johannesburg, and assemble everything here. That means if a client needs a part replaced, we can have it to them in 48 hours, not 4 weeks."
Their tailing ore extraction equipment lineup includes both wet and dry process options, but their wet process systems are particularly popular for high-clay tailings (common in parts of the Eastern Cape). These systems use a series of flotation cells and cyclones to separate lithium, and they're built tough: van der Merwe boasts that their equipment can run 24/7 for up to 18 months without major overhauls. "We test every machine in our Durban factory under extreme conditions—high dust, high humidity—to make sure it holds up in the field," he explains. They also offer a unique "pay-per-ton" model, where clients pay based on how much tailings they process, rather than upfront. "It lowers the barrier for smaller mines that might not have the capital to invest in a full plant," van der Merwe adds.
AMRS has also made strides in air pollution control system equipment , a critical consideration for mines near residential areas. Their extraction plants come with built-in dust collectors and HEPA filters that reduce particulate emissions by 99%. "Regulations are getting stricter, and that's a good thing," van der Merwe says. "Our systems help mines stay compliant while keeping their workers healthy." A recent project in the Bushveld Complex (a region known for platinum and chrome mining) saw AMRS install a 500-ton-per-day tailings plant that now recovers lithium as a byproduct—turning a previously unprofitable site into a multi-mineral operation.
NextGen Lithium Processing is the new kid on the block, founded in 2021, but they're already making waves with their focus on automation and data-driven extraction. "Traditional tailings processing is often a guessing game," says founder Naledi Dlamini, a former mining engineer with Anglo American. "Miners might adjust settings manually, but they don't have real-time data on how much lithium they're actually recovering. We're changing that."
Their Lithium Tailing Intelligence System (LTIS) is a game-changer. It combines their standard extraction equipment ( crushers, separators, ball mills with nano ceramic ball tech) with sensors and AI software that monitors every step of the process. "The system tracks particle size, lithium concentration, and energy use in real time," Dlamini explains. "If recovery rates ｄｒｏｐ by even 2%, it automatically adjusts the separator speed or ball mill rotation. Clients can log in from their phones to see live metrics—no more waiting for lab results." For large mines, this means less waste and higher yields. A gold mine in Free State that switched to LTIS last year reported a 12% increase in lithium recovery within the first month.
NextGen also offers training programs for mine workers, which is crucial in a sector facing skills shortages. "We don't just hand over the keys and leave," Dlamini says. "Our team spends 2 weeks on-site training operators to use the tech, and we offer monthly check-ins. It's about building capacity, not just selling equipment." Their focus on education has made them a favorite among government-backed mining initiatives, including a recent project with the Department of Mineral Resources to recover lithium from abandoned tin mine tailings in Mpumalanga. The project, which employs 30 local workers, is on track to produce 500 tons of lithium concentrate per year.
Southern Cross Extractors rounds out our list with a focus on affordability and scalability. Founded in 2015, they specialize in entry-level to mid-sized lithium tailings plants, making them ideal for startups or community mines. "Not everyone needs a 1,000-ton-per-day plant," says sales manager Lerato Mokoena. "We have options for operations processing just 10 tons per day, all the way up to 300 tons. And we finance them too—no need for huge upfront payments."
Their most popular model, the SC-150 Tailing Processor , is a compact, all-in-one unit that includes a crusher, ball mill, separator, and hydraulic briquetter —all for a price tag that's 30% lower than comparable imports. It's designed for ease of use, with a simple control panel and minimal maintenance needs. "We've had clients with no prior mining experience set up the SC-150 in under a week," Mokoena laughs. The briquetter, in particular, is a hit: it compresses extracted lithium into dense pellets that are easy to transport to refineries. "Refineries hate loose powder—it's messy and loses value in transit," Mokoena explains. "Our briquettes have a 98% density rate, so clients get top dollar for their lithium."
Southern Cross also prides itself on after-sales service. With a call center in Pretoria staffed 24/7, they're quick to troubleshoot issues. "A mine in the Northern Cape once called us at 2 a.m. because their separator jammed," Mokoena recalls. "Our technician walked them through fixing it over the phone in 15 minutes. Downtime costs money, so we take responsiveness seriously." Their commitment to small-scale miners has earned them a loyal following—they now supply equipment to over 40 community mines across South Africa, helping to drive local economic growth.
