Marathon Gold taps Metso Outotec for Valentine processing plant equipment

Marathon Gold has awarded Metso Outotec with orders for key processing equipment for the Valentine gold project in Newfoundland, Canada.

The combined order value of approximately €15 million ($14.9 million) has been booked in Minerals’ Sepetmber-quarter orders received.

“We chose Metso Outotec equipment because of their brand reputation, technology-oriented equipment, commitment to safety and environment, and their service footprint in Atlantic Canada,” Paolo Toscano, Vice President, Projects, Marathon Gold Corporation, said.

Metso Outotec’s scope of delivery consists of a VF Series™ grizzly feeder, a Nordberg® jaw crusher, Planet Positive Premier® SAG and ball mills, a Mill Reline Machine (MRM), vibrating screens and a high-rate tailings thickener with Reactorwell™ feed system.

Andy Lingenfelter, Vice President, Minerals Sales in North and Central America, added: “We are excited to work on the Valentine gold project with Marathon. We were able to align with the project’s key value drivers at an early stage and provide to-the-point technical support.

“Marathon has selected leading-class equipment for their gold production process, and they will also be able to benefit from our broad-based service organisation.”

An April 2021 feasibility study outlined an open-pit mining and conventional milling operation at Valentine with a 2.5 Mt/y processing rate over a 13-year mine life with a 31.5% after-tax internal rate of return and initial capital costs of C$305 million ($228 million). The project has estimated proven reserves of 1.4 Moz (29.68 Mt at 1.46 g/t) and probable reserves of 650,000 oz (17.38 Mt at 1.17 g/t).

Metso Outotec integrates tailings and water treatment solutions into one TMS offering

Metso Outotec says is introducing its comprehensive Tailings Management Solutions offering for the sustainable management of mine tailings.

The offering unites products with decades of process expertise and covers tailings thickening and dewatering as well as handling through conveying and dry stacking, it said. In addition, Metso Outotec offers a portfolio of solutions for the treatment of water produced during dewatering, enabling closed water loops while managing the level of impurities within the recycled water.

Dr Piia Suvio, Director, Tailings and Water, Metso Outotec, said: “The rising demand for sustainably mined materials and stricter environmental legislation are pushing the need for more advanced technology for safe processing and storing of the tailings. Water resource efficiency is also becoming more and more important. These factors, combined with the need to capture the full value of ore, for example, by reprocessing the tailings to extract the remaining valuable minerals, lead to a continuously increasing need for sophisticated tailings management solutions.”

Dr Suvio added: “With our extensive process expertise, we can offer cutting-edge technology solutions for any tailings management need to reduce water use, environmental impact, risks, and costs. Together with our customers, we can reshape the future of tailings and drive responsible management practices that help the business and society to prosper,” says Suvio.

Metso Outotec has been involved in the development of tailings management solutions and equipment for over 50 years. Today, a lot of emphasis is put on the design stage, which includes, for example, test work and studies supported by process simulations carried out with the recently launched Metso Outotec Geminex™ digital twin, allowing accurate plant design and sizing.

Metso Outotec’s Tailings Management Solutions consist of a wide range of Planet Positive equipment and feature performance and capacity guarantees:

  • Thickening plant units are based on Metso Outotec IPS, HRT, HCT and PT technologies. The Reactorwell™ feed system and Vane Feedwell™ provide enhanced mixing, dilution, and retention of the feed, maximising flocculant adsorption and aggregate growth. The advanced Metso Outotec control systems, such as the thickener optimiser, help improve the overall performance of the thickening plant unit;
  • Filtration plant units are based on proven FFP or FP-S filtration technology. The Metso Outotec filtration plant unit is specifically designed for high-volume tailings processing, leading to savings in operational and maintenance costs;
  • The company’s extensive conveying and stacking portfolio consists of robust components and is built to last and perform under even the toughest conditions; and
  • Metso Outotec process water recycling plants enable the recovery and reuse of water within the production process with enhanced metal recovery within the flotation circuit.

Metso Outotec says it supports its tailings management portfolio with a full range of parts, inspections, process optimisation and Life Cycle Services.

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.
