    Amermin–Ulterra critical minerals recycling: process and supply insights for miners

    Amermin–Ulterra critical minerals recycling: process and supply insights for miners

    First reported on MINING.com

    30 Second Briefing

    US recycler Amermin and Ulterra Drilling Technologies are extending their critical minerals recycling partnership to handle Ulterra’s waste streams from Argentina and Canada, on top of existing US volumes. The Texas-based firms already process more than 21 waste streams, including tungsten, cobalt, nickel, manganese, blast media, and synthetic and industrial diamond, and recycled over 1.4 million pounds of Ulterra material in 2025. Amermin is using an $11.5 million US Department of Energy grant to scale processing so end-of-life drilling and tooling inputs can be returned as manufacturing-grade feedstock.

    Technical Brief

    • Amermin’s flowsheet handles at least 21 distinct waste streams, including tungsten, cobalt, copper, nickel and zinc.
    • Precious and hard-phase recovery includes silver, carbon, iron, manganese, blast media, and synthetic/industrial diamond fractions.
    • DOE’s Office of Fossil Energy and Carbon Management is the funding channel for the US$11.5 million scale-up grant.
    • Recovered outputs are specified as “manufacturing-grade inputs”, implying metallurgical quality suitable for direct remanufacturing.
    • Supply-chain risk focus is on “geopolitically complex” sources, with recycling framed as an allied-supply alternative.
    • Ulterra’s drilling-tool waste becomes a controlled secondary ore stream, reducing primary mining demand for several critical metals.
    • Similar drill-tool recycling schemes could integrate with mine-site scrap segregation to pre-condition material for such refineries.

    Our Take

    The involvement of the U.S. Department of Energy’s Office of Fossil Energy and Carbon Management signals that Amermin’s recycling of tungsten, cobalt and other critical minerals is being treated as a strategic supply-security play, not just a waste-management exercise, which could ease future permitting and grant access in the USA.

    Recycling more than 21 distinct waste streams into critical minerals and blast media positions Amermin and Ulterra as potential suppliers into both mining and industrial-abrasive markets, giving them a hedge against commodity price volatility in individual metals such as nickel, copper or zinc.

    Within our 1201 Mining stories, only a subset of critical-minerals coverage involves large-scale secondary recovery; this 1.4-million-pound recycling effort in 2025 suggests that, for some operators, urban/industrial mining is starting to approach the materiality of smaller primary projects, especially for niche inputs like industrial diamond and rare earths.

    Minnova’s C$76M PL gold mine restart: economics and strip risks for engineers

    Minnova plans a C$76.2 million restart of the brownfield PL gold mine near Sherridon, Manitoba, targeting 62,200 oz per year over 10 years from a high‑grade open pit feeding an existing 1,000 t/d plant, which is slated to double to 2,000 t/d in year two. The September resource stands at 3.76 million measured and indicated tonnes at 4.98 g/t Au (601,158 oz) plus 1.67 million inferred tonnes at 3.78 g/t (202,810 oz), with open pits carrying a high 21:1 waste‑to‑ore strip ratio. At US$3,000/oz gold, the PEA projects an after‑tax NPV5 of US$180.6 million, 111% IRR, eight‑month payback and all‑in sustaining costs of US$2,288/oz, but value falls sharply at lower prices, underlining cost and strip sensitivity.

    Caterpillar Resource Industries leadership shift: fleet and autonomy cues for miners

    Caterpillar has confirmed that Denise Johnson, Group President of Resource Industries since 2016 and a key figure in expanding autonomous haulage and large mining truck platforms, will retire on 1 February 2027. Derrick York, currently President of Solar Turbines and a Caterpillar Senior Vice President overseeing industrial gas turbines and compressor sets, will become Group President of Resource Industries on 1 November 2026, with Johnson shifting to an advisory role. The handover timetable gives miners nearly a year of overlap to align major fleet, autonomy and support contracts with the incoming leadership.

    Anglo American copper scarcity and tech tie-ups: key takeaways for mine planners

    Tech companies are in talks to buy equity in Anglo American to secure long-term copper and other data centre metals, as Comex copper trades near $6.52/lb and LME cash copper recently hit a record $14,822/t. Anglo’s planned merger with Teck Resources would create a roughly $90 billion group producing about 1.2 million tonnes of copper per year, controlling around 5% of global supply, but is still awaiting Chinese antitrust clearance tied to concentrate flows to local smelters. Wanblad also warned Anglo may close its Brazilian nickel operations at Codemin and Barro Alto if the EU blocks the $500 million sale to MMG despite proposed long-term European ferronickel supply commitments.
