    One World Lithium DLCE nanobubble trials: process and scale-up notes for engineers

    One World Lithium DLCE nanobubble trials: process and scale-up notes for engineers

    First reported on MINING.com

    30 Second Briefing

    One World Lithium has delivered Moleaer industrial nanobubble generators to laboratories at the University of California, Irvine and the University of British Columbia to advance its single-step direct lithium carbonation extraction (DLCE) process. The collaboration aims to move from bench-scale to a mobile, containerised pilot plant at Moleaer’s Los Angeles facilities by early 2027, using CO₂ nanobubble extraction on natural brines to produce direct lithium carbonate and co-produce sodium, calcium, magnesium and potassium carbonates. Phase 2 lab work will test lithium-bearing clays, targeting acid-free extraction without sulphuric acid, soda ash, sorbents or multi-stage concentration.

    Technical Brief

    • Moleaer’s industrial nanobubble generators are now installed on-site at both UCI and UBC laboratories.
    • Two patent-pending DLCE applications were secured from earlier bench-scale work completed by June 2023.
    • UBC and UCI were formally engaged in June 2026 to collaborate with Moleaer on DLCE R&D.
    • Research methods include continuous laboratory testing on natural brines and lithium-bearing clays using CO₂ nanobubble contactors.
    • Phase 2 clay work focuses on formulating lithium slurries and testing carbonate production under varied operating conditions.
    • Process design intentionally excludes sulphuric acid, soda ash, sorbents and multi-stage concentration, targeting simplified flowsheets.

    Our Take

    Lithium and lithium carbonate pieces in our database increasingly sit at the intersection of 'Research' and 'Sustainability' tags, signalling that lab-scale separation technologies like OWL’s DLCE are becoming a key competitive lever rather than a side-stream R&D activity.

    The presence of sodium, calcium, magnesium and potassium in the chemistry focus aligns with other brine-processing items in our database, where operators are looking to monetise or at least neutralise multi-ion streams, suggesting DLCE’s commercial success may hinge on how it handles these co-ions rather than lithium alone.

    Hitachi Construction Machinery Americas Bell ADTs: fleet planning notes for mines

    Hitachi Construction Machinery Americas, set to be rebranded as LANDCROS Americas in April 2027, is adding three Bell Equipment articulated dump trucks to its North American lineup, the ZD30, ZD45 and ZD50, covering the 30–50 t class. The models, due for launch in early 2027, target mine haul and large earthworks fleets needing mid-range payload options between rigid trucks and smaller ADTs. For mine planners and contractors, the move broadens mixed-fleet choices and may simplify parts and dealer support across Hitachi-branded loading and haulage assets.

    Martin Engineering urethane belt sealing: dust and spillage lessons for mine engineers

    Martin Engineering has rolled out a new portfolio of polyurethane conveyor belt sealing systems for transfer points across Europe, the Middle East, Africa and India, aimed at eliminating spillage and fugitive dust where bulk materials load onto moving belts. The urethane skirting and sealing designs target common leakage zones at loading chutes and skirtboards, offering longer wear life than rubber and tighter control of the loading zone. For mine operators, the systems are intended to reduce cleanup labour, limit dust exposure around transfer points and stabilise belt tracking.

    Epiroc drill bit recycling programme: circular consumables insights for mine teams

    Epiroc is rolling out a Drill Bit Recycling Program that lets mine operators return end‑of‑service rock drilling bits so tungsten carbide and steel can be recovered and fed back into new tool production. The scheme targets worn top hammer and down‑the‑hole bits that still contain high‑value hardmetal inserts, reducing primary raw material demand and scrap disposal. For drill and blast teams, this formalises a closed-loop route for consumables procurement and waste management without changing existing drilling parameters or fleet.
