Superior Industries to showcase eight new products at CONEXPO-CON/AGG 2023

US-based bulk material processing and handling systems specialist, Superior Industries Inc, is planning to showcase more than 250 tons (227 t) of products at CONEXPO-CON/AGG 2023 in Las Vegas, Nevada, in March, with at least eight of the products representing brand new launches.

Included among this new product offering is an expanded cone crusher portfolio, with two brand-new cone models introduced and shown alongside Superior’s Patriot® Bushing Cone.

Superior explained: “First, the Dakota™ Bearing Cone, which will earn credibility for its efficient use of horsepower per tonne, a straightforward lubrication system, and a wide range of liner profiles. The other new cone crusher will be called the Endeavor™ Spider Bushing Cone. Operationally, it’s an uncomplicated design that accepts a wide range of feed sizes with an adjustable stroke for fine tuning.”

Superior also plans to display its Liberty® Jaw, Valor® VSI, and Sentry® HSI crushers.

In addition to this, Superior plans to debut a new quick-to-erect modular wash plant.

According to Superior, its increasingly broad portfolio of Fusion® Modular Platforms are a good match for aggregate producers seeking semi-static plants that are easy to install and maintain with a more economical price tag than portable plants or design-build projects. On display, the company plans to erect a 8 x 20 ft (2.4 m x 6.1 m), three-deck Guardian® Horizontal Wet Screen Fusion Platform with an Aggredry® Dewatering Screen attached to one of the discharge points.

In 2023, it will mark the eighth time Superior will display its famed TeleStacker® Conveyor (pictured) at CONEXPO-CON/AGG – and each show there is new technology to showcase and new success stories to share. With radial travel, variable height and a telescopic conveyor, TeleStacker Conveyors stockpile material in a way that overcomes material segregation. This show, Superior will display a 42 in (1.06 m) x 170 ft (52 m) XTP Swing Axle model with a working automation panel that visitors can interact with in the booth.

Lastly, Superior will display a wide variety of its own conveyor components, with the manufacturer planning to show more than three dozen individual idlers, pulleys, scrapers and other conveyor accessories. New products include a redesigned line of Exterra® Belt Cleaners with some brand-new options, a modular Load Zone Skirting System for dust and spillage control, and unique Application-Specific Idler Bearing Seals for longer-lasting idlers in demanding conditions.

CONEXPO-CON/AGG 2023 will run from March 14-18, 2023, in Las Vegas, Nevada. International Mining is a media sponsor of the event

Tungsten West set to bring Hemerdon tungsten-tin mine back into production

Tungsten West, the mining company focused on recommencing production at the Hemerdon tungsten and tin mine in Devon, England, has announced its intention to proceed with an initial public offering on London’s AIM market.

The company has conditionally raised £39 million ($53 million) before expenses, with plans to debut on the bourse on October 21 with a market capitalisation of approximately £106.2 million.

The net proceeds of the offer, together with the $49 million project financing from a fund managed by Orion Resource Partners, will be used to, among other things, execute the planned capital expenditure and corporate commitments of £44.6 million for improvement works at the Hemerdon Mine, bringing it back into commercial production.

Hemerdon is, Tungsten West says, the third largest tungsten resource globally, as well as being a previously producing mine that was operational from 2015-2018. Tungsten West purchased the Hemerdon Mine in 2019, and has since completed a bankable feasibility study that demonstrated an extensive reserve of approximately 63.3 Mt at 0.18% W and 0.03% Sn, as well as 37.4 Mt of saleable aggregate material. The company estimates that the life of mine is currently 18.5 years with the opportunity to extend this through future investment.

The mine already has the majority of its infrastructure in place, with previous owner Wolf Minerals Ltd having invested over £170 million into the development of the mine and its processing facilities, which include an open-pit mine, mineral processing facility and mine waste facility, the company says. With a substantial amount of existing infrastructure, the development costs associated with re-starting the mine are estimated to be £44.6 million. This existing infrastructure also means that the rebuild is only expected to take 12 months, with parts of the restart project already underway.

Having acquired the mine out of a receivership process, Tungsten West completed a significant amount of work to enable it to understand and address the issues historically experienced by Wolf Minerals, including a 6,113 m geological exploration drilling program and several technical studies. The company has identified the past issues experienced by Wolf Minerals that required rectifying.

“One of the main issues was a poor mineral process route design, with several items of equipment, particularly in the front end of the plant, causing plant downtime and hindering the recovery of the tungsten and tin minerals,” Tungsten West says. “Tungsten West has therefore designated a material proportion of its rebuild costs to modifying and updating the front-end of the processing plant. This will include replacing the existing crushing circuit with new duty and standby primary jaw crushers and secondary cone crushers.”

In addition, the introduction of X-ray Transmission ore sorting, which the company previously carried out tests on with TOMRA Mining in Germany, substantially reduces processing costs by rejecting around 70% of the ore fed to the sorters, it says.

Further upgrades to the plant commenced by the previous operator will be completed, including the dense media separation feed stockpile where 24 hours of surge capacity will be installed, decoupling the front-end of the plant from the concentrator circuit.

“Through these actions, the company expects plant operating time to improve from circa-53% under previous operatorship to the industry standard of circa-81% under Tungsten West,” Tungsten West says.

Tungsten West has identified further opportunities for by-product cash flow through the production and sale of aggregates. A new aggregate plant will be fed with ore sorter rejects and with the waste streams from the processing plant. The business plan is to sell to local aggregate consumers, such as GRS, providing them with a stable, long-term and sustainable source of these materials.

The company says it has implemented a number of initiatives to ensure a minimal impact on the surrounding environment and local community. These include optimising the plants low frequency noise to ensure minimal environmental impact and a fully cash funded £13.2 million restoration bond.

Max Denning, CEO of Tungsten West, says: “With the proposed £39 million raise announced today, and the £36 million funding package from Orion, we will be fully funded for the development of Hemerdon back into production. We look forward to welcoming new investors into this compelling business and working with all our stakeholders to ensure that the newly reinvigorated Hemerdon mine is a beacon of mining excellence in the UK.”

Metso Outotec to supply Vertimills, cone crusher to IAMGOLD’s Côté project

Metso celebrates 10,000th Nordberg HP cone crusher sale

Metso says it has reached the significant milestone of 10,000 Nordberg® HP cone crushers sold globally.

The most popular modern cone crusher in the world, the company says, the HP Series™ celebrates its 30th anniversary this year.

The 10,000th HP cone crusher unit was handed over to the French aggregates and asphalt producer and urban infrastructure development company, Eurovia, in a ceremony held today at Metso’s Mâcon facility in France.

Arto Halonen, Vice President, Aggregates Crushers at Metso, said: “The HP is undoubtedly one of Metso’s most widely used innovations. It’s a technology that has been evolving throughout the years to meet customers’ changing needs, making their operations more successful through proven performance and reliable output. That’s most likely why HP has become an industry standard for a variety of aggregates and mining applications.”

The origin of the HP Series cone crusher can be tracked back to Milwaukee, USA, in the early to mid-1980s. “The technological breakthroughs by the Nordberg research program re-defined crushing performance and provided the basis for a new type of cone crusher introduced in 1989: the Nordberg High-Performance cone crusher series, today simply known as the HP,” Metso said.

Today, HP cone crushers are engineered and manufactured in Metso’s competence centre in Mâcon, France, with manufacturing also in Brazil, China and India.

A versatile crusher, it is used in a wide range of fixed and mobile applications, varying from limestone to taconite and ballast production to manufactured sand, Metso said.

Halonen continued: “Know-how from developing the HP and from thousands and thousands of customer applications around the world has played an integral part in Metso research and development initiatives in crushing.

“This is an important milestone for Metso and we want to thank our customers for their continued confidence in us during the first 30 years of the HP’s journey and look forward to explore new development possibilities in the years to come.”
