    Atlantic Strategic monazite plant: viability, scale-up and feedstock notes for engineers

    Atlantic Strategic monazite plant: viability, scale-up and feedstock notes for engineers

    First reported on MINING.com

    30 Second Briefing

    Atlantic Strategic Minerals has confirmed the technical viability of a domestic rare earth processing facility in Virginia, with a feasibility study backing a monazite demonstration plant designed to produce 1,000 tonnes per annum of monazite concentrate from existing byproduct streams. The company plans to commission the demo plant within about 12 months at its Stony Creek mineral separation complex, already the largest ilmenite and zircon facility in North America. Capacity could later scale to roughly 5,000 tonnes per annum via plant expansion and third-party feedstock, creating a larger US rare earth-bearing supply source.

    Technical Brief

    • Study relies on “established processing pathways”, indicating no dependence on unproven extraction or separation technology.
    • Monazite circuit will utilise byproduct streams from current mineral sands operations, reducing mining and haulage requirements.
    • Scaling through third-party monazite feedstock implies future logistics, blending and specification-control challenges at Stony Creek.
    • For other US mineral sands operators, the project provides a potential domestic outlet for monazite-rich byproducts.

    Our Take

    Rare earth and monazite items are a small subset of our 1203 Mining stories, so a Virginia‑based processing route positions Atlantic Strategic Minerals in a relatively uncrowded North American mid‑stream segment compared with more frequently covered gold or base‑metal projects.

    The planned five‑fold capacity scale factor at ASM’s Virginia facilities implies a heavy reliance on third‑party monazite and mineral sands feedstock, which could draw in smaller ilmenite and zircon producers in the USA that currently export concentrates rather than upgrade domestically.

    With a 12‑month commissioning timeframe for the demonstration plant, ASM’s rare earths pathway is likely to reach a decision point well before large US tungsten and gold projects in Nevada and elsewhere that carry much higher capex figures in our database, potentially giving it a timing advantage in securing offtake and policy support.

    PLS Pilgangoora 22-sorter TOMRA contract: process design notes for engineers

    TOMRA Mining has secured a contract from Pilgangoora Operations Pty Ltd, a PLS Group subsidiary, to supply 22 sensor-based ore sorters for the P2000 Expansion Project at the Pilgangoora lithium operation in Western Australia. The installation is part of PLS’ pre-Final Investment Decision early works, signalling commitment to large-scale sorting ahead of full project sanction. For process engineers, the move points to increased reliance on front-end sensor-based separation to upgrade run-of-mine feed and manage lithia grade variability before downstream concentration.

    Macmahon’s 42‑month Telfer Gold Mine extension: planning notes for project teams

    Macmahon Contractors has secured a 42‑month extension to provide contract mining services at Greatland Resources’ Telfer Gold Mine in Western Australia, valued at A$485 million over the term. The deal locks in a multi‑year mining services pipeline at one of the state’s major gold operations, supporting continuity of fleet deployment, workforce planning and site-based maintenance. Contractors and suppliers can expect sustained demand for open-pit and underground support services, consumables and rebuilds tied to Telfer’s existing mine plan.

    Metso–Valmet Flowrox pump deal: slurry circuit implications for mine engineers

    Metso has agreed to acquire Valmet’s Flowrox™ peristaltic hose pump and progressive cavity pump technologies, including associated spare parts and service capabilities, targeting abrasive and chemically aggressive slurry duties in mining and minerals processing. The deal adds positive displacement options alongside Metso’s existing slurry and submersible pump lines, enabling tighter process control in applications such as thickener underflow, filter feed and reagent dosing. For operators, the integration should simplify lifecycle support and parts standardisation across critical slurry handling circuits.
