how fines dry magnetic separation could solve mining's tailings problem

For decades, tailings have been known as a necessary evil in mining. World Mining Frontiers writer Andrea Valentino talks to Sunil Tripathy, an expert in mineral extraction at the University of Lorraine, about how new fines dry magnetic separation (FDMS) could finally put tailings out to pasture, and investigates the impressive work done by Vale.

On another hot day in January 2019, just around noon, as the sun was reaching its peak, hundreds of miners at the Crrego do Feijo mine were settling down for a break. And why not? Iron mining is hard work especially in a poor part of Brazil like Minas Gerais, where miners often make less than 4 ($5.6) an hour.

But barely could the workers begin their meals than their moment of rest was destroyed suddenly and irreparably. After a nearby dam collapsed, 12,000,000 cubic metres of mud and debris catapulted at 50mph into the building and the miners.

After days of frantic searches, the terrible toll of the accident became clear: 259 people, most of them miners, were confirmed dead. 11 victims were never found, their bodies lost forever in the flood. In the investigation that followed, it became clear that Vale, the mines owner, had made serious mistakes. Among other things, the sirens meant to alert workers of a collapse failed to ring.

Yet examine what happened that terrible day, and these problems pale in comparison to something much more fundamental the reason the dam was there in the first place. Because it used a traditional form of ore separation, creating a colossal pile of muddy waste known as tailings, Vale had to build a dam to store all the slurry.

A disaster was, arguably, just a matter of time. And even if the Crrego do Feijo dam had never collapsed, these tailings create problems all of their own, eroding landscapes, releasing toxic metals and poisoning water supplies.

Though figures on extraction equipment are scarce, numbers from Grand View Research suggest that the global mining equipment market size was valued at $144.37bn in 2019, and is expected to expand by 12.7% a year from 2020 to 2027.

A corollary of all this growth has traditionally meant an avalanche of waste. To illustrate quite how much, Sunil Tripathy, an expert in mineral extraction at the University of Lorraine, takes as his example arguably the most important alloy on earth: steel.

For every thousand tonnes that ends up in skyscrapers or fighter jets, Tripathy explains, processors started with about double that quantity of raw iron ore. Given countries like China pump out nearly a billion tonnes of steel each year, that means one monumental scrapheap.

The mineral is first crushed then funnelled past an electromagnet, the precious material sucked away to safety and the waste product left down below. In so-called wet magnetic separation, water is added too, particularly when refining lower-quality ores.

Whatever its flaws, this technique is cheap and straightforward enough to ingratiate itself with mining engineers the world over. According to work by Research and Markets, the appetite for magnetic separation is expected to reach nearly $1bn by 2025, up from just $685m in 2019.

Even so, wet magnetic separation is far from perfect. Nor do you have to look to massive disasters like the Crrego do Feijo collapse to see it. After being mixed with water, after all, the leftover ore turns into a kind of thick sand. And though it doesnt always end up behind an unstable dam, it does always have to be put somewhere whether piled up into hills or dumped into ditches.

Whats in no doubt, though, is its desultory environmental impact. In 2008, more than 1,500 Canadian ducks died after landing on a tar sands tailing pond in Alberta, while earlier this year, a tailings spill in China polluted a river that serves 200,000 people. These problems extend to the water itself.

As Tripathy notes, the recirculation rate in wet magnetic separation is very low, with upwards of 60% ending up polluted and undrinkable. And given Brazilian miners alone used 250 billion litres of water to produce just 450 tonnes of steel in 2016, thats a colossal strain on the environment.

Even before the 2019 disaster, Vale was busy looking for alternatives to wet magnetic separation. The eventual breakthrough the company made came too late for the victims in Minas Gerais, but it could transform life for other miners and the local environment.

Developed by New Steel, a Vale subsidiary, a company spokesman recently boasted that itll be able to concentrate 30 metric tonnes of ore every single hour. Thats not bad considering the initial investment was a mere $100m.

At the heart of the new system are some incredibly powerful magnets. Made from rare earth metals, they can separate iron ore and other minerals far easier than ceramic alternatives. After crushing the ore, drying it and divvying particles by size, Vales engineers let the super magnets do their thing.

Of course, that still leaves waste material. But because theres no water, its in the form of solid grit rather than muddy tailings. This makes it far simpler to store safely, typically in tidy mounds that can eventually be reclaimed by nature.

No wonder, then, that Tripathy is so enthusiastic about the environmental benefits of FDMS. Water scarcity is a major problem, and maintaining tailing ponds is completely unsustainable. In other words, dry processing has to be adopted as soon as possible.

Nor is it surprising that Vale is adopting its new technology so aggressively. With that initial $100m investment under its belt, the company hopes to spend a further $3.1bn on dry processing facilities over the next few years, and ultimately aims to process 70% of its iron ore water-free by 2024.

As Marcello Spinelli, a director at Vale, said in a July press release: New Steel puts Vale at the forefront of investments in ore processing technology. We will continue to seek solutions that increase the safety of our operations.

All the same, Tripathy is careful to warn that FDMS is not without its flaws. For starters, he says, its rare earth magnets are so powerful that they risk attracting dust and other impurities alongside the precious metals. Particle size is challenging in another way too.

As Tripathy explains, some types of FDMS cant separate ores smaller than 45 frustrating given iron ore particles can be as small as 30. Then there are more fundamental problems of magnetic separation. Materials like iron are perfect for FDMS, after all, but what about non-magnetic metals like aluminium, copper or zinc?

Whatever the challenges of FDMS, however, Tripathy is basically optimistic about the technologys potential. Though it makes the process slightly more expensive, he notes its not a big thing to refine magnetised iron of dust impurities.

Among other things, companies are exploring the viability of digital twin systems, creating computer models of how ore reacts to magnets, then tweaking their real-world counterparts to sharpen efficiency.

Finally, Tripathy suggests that these developments are unimportant when compared with environmental necessity. You need the right technology to avoid water, he says. Your community and your future are dependent on it. A fair point, especially if you examine how climate change is drying out the planet at startling rates.

Even in Brazil, home to the worlds largest rainforest, four million people lack access to safe water. Hopefully FDMS can start redressing the balance and stopping tailings from snuffing out the lives of more poor miners, in Minas Gerais or anywhere else.

Dry low-intensity magnetic separation is confined mainly to the concentration of coarse sands which are strongly magnetic, the process being known as cobbing, and often being carried out in drum separators. Below the 0.5 cm size range, dry separation tends to be replaced by wet methods, which produce much less dust loss and usually a cleaner product. Low-intensity wet separation is now widely used for purifying the magnetic medium in the dense medium separation process, as well as for the concentration of ferromagnetic sands.

Drum separators are the most common machines in current use for cleaning the medium in DMS circuits and are widely used for concentrating finely ground iron ore. They consist essentially of a rotating non-magnetic drum (see attached figure 1 drum separator) containing three to six stationary magnets of alternating polarity, although the Permos separator uses many small magnet blocks, whose direction of magnetisation changes in small steps. This is said to generate a very even magnetic field, requiting less magnetic material. figure 1 drum separator Although initially drum separators employed electromagnets, permanent magnets are used in modern devices, utilising ceramic or rare earth magnetic alloys, which retain their intensity for an indefinite period. Separation is by the pick-up principle. Magnetic particles are lifted by the magnets and pinned to the drum and are conveyed out of the field, leaving the gangue in the tailings compartment. Water is introduced into the machine to provide a current which keeps the pulp in suspension. Field intensities of up to 0.7 T at the pole surfaces can be obtained in this type of separator. The drum separator shown in figure 1 is of the concurrent type, whereby the concentrate is carried forward by the drum and passes through a gap, where it is compressed and dewatered before leaving the separator. This design is most effective for producing an extremely clean magnetic concentrate from relatively coarse materials and is widely used in dense medium recovery systems. The separator shown in figure 2 is of the counter-rotation type, where the feed flows in the opposite direction to the rotation. This type is used in roughing operations, where occasional surges in feed must be handled, where magnetic material losses are to be held to a minimum, while an extremely clean concentrate is not required, and when high solids loading is encountered. figure 2 Counter-rotation drum separator Figure 3 shows a counter-current separator, where the tailings are forced to travel in the opposite direction to the drum rotation and are discharged into the tailings chute. This type of separator is designed for finishing operations on relatively fine material, of particle size less than about 250 m. Drum separators are widely used to treat low grade taconite ores, which contain 40-50% Fe, mainly as magnetite, but in some areas with hematite, finely disseminated in bands in hard siliceous rocks. Very fine grinding is necessary to free the iron minerals that produce a concentrate that requires pelletising before being fed to the blast furnaces. figure 3 Counter-current separator In a typical flowsheet the ore is ground progressively finer, the primary grind usually being undertaken autogenously, or by rod milling, followed by magnetic separation in drum separators. The magnetic concentrate is reground and again treated in drum separators. This concentrate may be further reground, followed by a third stage of magnetic separation. The tailings from each stage of magnetic separation are either rejected or, in some cases, treated by spiral or cone concentrators to recover hematite. The cross-belt separator (see attached figure 4) and disc separators once widely used in the mineral sands industry, particularly for recovering ilmenite from heavy mineral concentrates, are now considered obsolete. They are being replaced with rare earth roll magnetic separators and rare earth drum magnetic separators. figure 4 Cross-belt separator Rare earth roll separators use alternate magnetic and non-magnetic laminations. Feed is carried onto the magnetic roll by means of a thin belt as shown in Figure 4, hence there is no bouncing or scattering of particles as they enter the magnetic zone, and they all enter the magnetic zone with the same horizontal velocity. These factors contribute to achieving a sharp separation. Roll speed can be adjusted over a wide range, allowing the product quality to be dialled in. Dry rare earth drum separators provide a fan of separated particles which can often be seen as distinct streams (see attached figure 5). The fan can be separated into various grades of magnetic product and a nonmagnetic tailing. In some mineral sands applications, drum separators have been integrated with one or more rare earth rolls, arranged to treat the middlings particles from the drum as shown in Figure 5. figure 5 A laboratory dry rare earth drum separator Pictures of Drum Separators Pictures of drum separators produced by Henan Deya Machinery Co., Ltd. magnetic-separator_01magnetic-separator_11magnetic-separator_10magnetic-separator_09magnetic-separator_08magnetic-separator_07magnetic-separator_06magnetic-separator_05magnetic-separator_04magnetic-separator_03magnetic-separator_02
