Metso Outotec delivers new generation feedwell for improved thickener, clarifier performance

Metso Outotec says it is launching the Metso Outotec Reactorwell™, a new generation feedwell for maximising thickener and clarifier performance while minimising flocculant consumption and bringing significant operational cost efficiencies.

The feed system features high solids retention and mixing efficiency. It also eliminates feed short-circuiting and offers low shear for ideal floccule growth and even discharge symmetry, the company said.

The new feed system provides optimum feed conditioning for thickeners and clarifiers, and, thanks to its many benefits in addition to low flocculant usage, the Reactorwell is part of Metso Outotec’s sustainable Planet Positive portfolio.

Brian Berger, Vice President, Thickeners and Clarifiers at Metso Outotec, said: “The Reactorwell enables a big leap forward in thickener and clarifier performance as it utilises maximum settling area due to its high exit symmetry. It also provides improved overflow clarity as well as higher underflow density. Additionally, the Reactorwell allows better thickener operability with an improved response to process changes.

The Reactorwell is, the company says, easy to maintain due to its intelligent design and modularity. It consistently achieves high unit area throughput and the improved Autodil™ performance minimises the need for pumped dilution, leading to lower total cost of ownership.

Metso Outotec’s Concorde Cell flotation tech to recover fine and ultra-fine particles

Metso Outotec says it is launching its groundbreaking Concorde Cell™ flotation technology to provide efficient fine and ultra-fine particle recovery.

This Planet Positive technology sets a new benchmark in high-intensity pneumatic flotation, reducing plant operation costs and contributing to sustainability of operations through minimised energy and water consumption per tonnes of metal produced, the OEM said.

Back in August, Metso Outotec said it would supply Concorde Cell technology to a “major nickel producer” in Western Australia as part of its concentrator modernisation. It later turned out that this was for BHP Nickel West at the Mount Keith operation where the concentrator capacity is being increased from 10.5 Mt/y to 12 Mt/y, and ultimately 15 Mt/y.

The patented Metso Outotec Concorde Cell technology is the first fine and ultra-fine flotation solution for more finely disseminated and complex orebodies that have previously been inaccessible, according to the company.

Antti Rinne, Vice President, Flotation at Metso Outotec, said: “The need to process more finely disseminated and complex ore grades, as well as the declining ore grades and the demand for improved flotation selectivity, all bring new challenges to minerals processing flowsheets. The new Concorde Cell technology helps flotation circuits overcome these challenges and recover the previously unachievable ore value.”

The Concorde Cell forced-air Blast Tubes treat 100% of fresh feed combined with tailings recycling for improved performance, allowing, Metso Outotec, says finer grinding to get extra liberation without the risk of valuable particles lost into tailings. It also provides a very high shear environment with increased bubble surface area flux for faster flotation kinetics, plus optimised froth recovery and improved selectivity, the company said.

“Combining the well-proven TankCell® technology with Concorde Cells is a low-risk and high-benefit approach for minerals processing flowsheets,” Rinne said. “The cell produces very high shear and extremely fine bubbles, which increases recovery in particles under 20 microns.”

The offering also includes Blast Tube retrofit kits for upgrading the metallurgical performance of self-aspirated pneumatic flotation cells to the Concorde Cell technology. In addition, Metso Outotec says it can provide a complete slurry handling package for the Concorde Cell, including pumps, spare parts, as well as optimisation and maintenance services.

Metso Outotec invests in Lappeenranta filtration technology centre

Metso Outotec is opening a new laser welding unit, customised for demanding production conditions, at its filtration technology centre in Lappeenranta, Finland.

The new laser welding unit will add to the centre’s manufacturing capacity and enable the production of higher-quality welded structures in a safer and more environmentally friendly manner, the company says. The value of the investment is approximately €1 million ($1.2 million).

Markku Teräsvasara, President of Metso Outotec’s Minerals business, says: “Investing in an efficient laser welding unit is one example of our desire to focus on being an industry leader also in filtration technology.

“In Lappeenranta, we produce several types of filters used in demanding industrial applications. We have systematically developed our capabilities in Lappeenranta over the years. Today, the technology centre for solid-liquid separation, which we opened in 2015, serves customers around the world.”

In addition to Lappeenranta, Metso Outotec provides filtration technology to customers worldwide from its Turku and Suzhou facilities in China, Jussi Venäläinen, Vice President of Metso Outotec’s Filtration Business Line says.

“Our filtration equipment is used, for example, in the mining, chemical and food industries,” he says. “All of them require reliable filtration to ensure high quality of their end products.”

Metso Outotec says its filtration technology centre in Lappeenranta plays an important role in the development of industry innovations. In addition to manufacturing, the centre operates a Dewatering Technology Center, which is focused on solid-liquid separation. It also has continuous cooperation with the Lappeenranta-Lahti University of Technology, among others.

Venäläinen added: “We have a long legacy of filtration expertise – our first filters were made as early as the 1930s in Sala, Sweden. Our selection of filtration technologies is the largest in the field, and their energy, emission and water efficiency is in a league of its own.

“Most of the filtration solutions are part of our Planet Positive range of products. Our filters are safe, easy to use, and quick to maintain, and their high level of automation enables continuous optimisation and remote support. We also provide comprehensive filter maintenance, including lifecycle services.”

Metso Outotec has carried out more than 14,000 filtration tests and delivered more than 5,000 filters for various applications worldwide. Most of the filters are sold under the Larox® product name along with Metso Outotec corporate branding.

In Finland, industrial filter production began in 1977 in Lappeenranta under Larox Oy. In 2009, it continued under Outotec (Filters) Oy, and, after the Metso Minerals and Outotec merger, the filtration technology centre became a part of Metso Outotec. The Lappeenranta site employs around 200 people.

Metso Outotec to deliver ‘multiple’ Vertimills to Ferrexpo’s Ukraine iron ore ops

Metso Outotec is to deliver multiple energy-efficient Vertimill® VTM-3000 stirred mills to Ferrexpo in Ukraine, with the vertical grinding mills set to become the largest of their kind to be installed in the country.

Once the mills have been installed, Ferrexpo’s iron ore beneficiation complex will be the largest VTM installation on the continent, Metso Outotec said, with several Vertimills already operating at the plant.

Typical values for this type of an order is in the range of €30-40 million ($35.7-47.6 million), depending on the scope of delivery, the company said. The order was booked in the company’s Minerals’ June quarter orders received.

Vertimill technology is part of Metso Outotec’s Planet Positive offering, providing the lowest total cost of ownership compared with other grinding mills in many applications thanks to its high energy efficiency, reduced media consumption, low installation cost as well as minimal liner wear and maintenance, the company claims. It is capable of handling feed sizes of up to 6 mm and grinding to product sizes of 30 microns or less. Vertimill is available in standard mill sizes ranging from 11 kW to 3,352 kW.

Ferrexpo has plans to increase output from its iron ore operations in Ukraine from 32 Mt/y to more than 80 Mt/y.
