    allmineral separation suites: integrated ore sorting design notes for plant engineers

    allmineral separation suites: integrated ore sorting design notes for plant engineers

    First reported on International Mining – News

    30 Second Briefing

    allmineral is expanding from its core wet and dry processing technologies – including air-pulsed density separation, fluidised bed density sorting, magnetic separation and jigging – into integrated ore sorting solutions. Director of Business Development Richard Monteiro Ferreira describes a “separation suite” approach that combines sensor-based ore sorters with downstream jigging and fluidised bed units to optimise cut-off grades and reduce plant mass pull. For plant designers, the key shift is treating ore sorting as a front-end upgrade stage tightly coupled to existing gravity and magnetic circuits rather than a standalone bolt-on.

    Technical Brief

    • Ferreira stresses pre-concentration design must consider sorter by-pass and recirculation streams in the overall mass balance.
    • Sensor-sorter accept/reject criteria are tuned to match downstream jig and fluidised bed cut densities.
    • Control philosophy links sorter product streams to jig stroke/frequency adjustments for stable separation performance.
    • Brownfield retrofits are being engineered as modular “separation suites” to minimise tie-in downtime during plant upgrades.
    • allmineral is targeting orebodies with highly heterogeneous gangue mineralogy where density contrast suits jigging post-sorting.
    • Ferreira notes that sorter feed preparation (top size, fines removal, moisture control) is now a core flowsheet design task.
    • For new plants, the company is pushing trade-off studies comparing capital for larger mills versus higher-intensity front-end separation suites.

    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.
