    Rosh Pinah Zinc water treatment plant: water balance and throughput notes for engineers

    Rosh Pinah Zinc water treatment plant: water balance and throughput notes for engineers

    First reported on International Mining – News

    30 Second Briefing

    Rosh Pinah Zinc and Appian Capital Advisory have commissioned a new process water treatment plant at the Rosh Pinah mine in Namibia as a core element of the RP2.0 expansion. The plant is engineered to retreat and recycle process water from multiple circuits across the operation, cutting freshwater draw and reducing discharge volumes to the site’s TSF and evaporation facilities. For mine planners and process engineers, the scheme tightens the site water balance and may enable higher throughput under existing abstraction permits.

    Technical Brief

    • Plant design treats process water from multiple operational areas, requiring cross-plant piping and control integration.
    • Centralised treatment allows tighter control of water chemistry fed back into the concentrator.
    • Reduced discharge to the TSF is expected to moderate supernatant pond growth and associated stability risks.
    • Lower volumes routed to evaporation facilities should cut operating costs and footprint for future pond expansions.
    • Water recycling capacity is intended to support higher mill utilisation without renegotiating abstraction licences.
    • Similar retreatment plants are increasingly being tied to brownfield expansion phases to unlock latent throughput.

    Our Take

    Rosh Pinah Zinc’s earlier commissioning of Namibia’s first paste backfill plant at the same mine signals a pattern of investing in underground water and tailings management, so a new water treatment plant likely tightens the mine’s overall water balance and reduces reliance on surface storage.

    With Appian Capital Advisory backing both the RP2.0 expansion project and the paste backfill upgrade at Rosh Pinah Zinc, the water treatment plant fits a consistent private-equity playbook in our database of de-risking legacy African base-metal assets through incremental ESG-focused infrastructure.

    Schlam installation kit programme: interface control and uptime gains for mines

    Schlam has launched a new in-house engineered installation kit programme for mining truck bodies and excavator buckets, giving sites a standardised, end-to-end package covering attachment supply and fit-out. Developed under a three-year product development effort, the kits are designed to integrate with Schlam’s load and haul attachments, reducing the need for bespoke on-site fabrication and ad hoc hardware selection. For maintenance and asset teams, this points to more predictable installation times, simplified spares management and tighter control of attachment interface geometry.

    Integra’s 74% reserve lift at Florida Canyon: project economics for mine planners

    Integra Resources’ updated feasibility study for the Florida Canyon heap leach mine in Nevada lifts proven and probable reserves 74% to 1.1 million oz at 0.31 g/t, raises planned output to 82,000 oz gold per year over eight years, and boosts the 5% NPV to US$601 million using a US$4,200/oz price. All-in sustaining costs climb 43% to US$2,331/oz with recovery steady at 62%, but post-tax free cash flow is projected at US$800 million, averaging US$90 million annually. Integra is drilling 42,500 metres around the existing operation to grow resources and fund its DeLamar gold-silver project in Idaho.

    DRC critical minerals strategy: price-setting and supply risks for mine planners

    Democratic Republic of Congo has shifted from price-taker to price-setter in cobalt by imposing ARECOMS-managed export quotas and planning state stockpiles of cobalt, coltan and germanium. Cobalt prices have climbed from about $21,000/t in early 2025 to just over $56,000/t, with Kinshasa forecasting $2.3 billion in fiscal revenues this year versus an estimated $617 million without intervention. Advisory input from Vectus Global and new investment moves such as Virtus Minerals’ acquisition of Chemaf signal tighter supply discipline and a push for higher value-added partnerships.
