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

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.
