Flowsheet Development and Optimization

Flowsheet Development and Optimization

Capabilities

Sequential, progressively aggressive leach protocols combined with inter-stage cyanidation to determine gold deportment across mineral species. Analogous protocols for copper mineral identification. Critical for selecting the optimal processing route.

Development of complete flowsheets from testwork data, including circuit configuration, equipment selection, reagent schemes, and operating parameters for grinding, flotation, leaching, gravity, and hydrometallurgical circuits.

Systematic testing to define the trade-off between concentrate grade and metal recovery, enabling economic optimization for your specific ore and market conditions.

Evaluation of collectors, frothers, depressants, pH modifiers, and specialty reagents. Dosage optimization and cost-per-tonne analysis for flotation, leaching, and hydrometallurgical circuits.

Multi-stage recycle tests simulating continuous plant operation to generate steady-state data for equipment sizing, water balance, and reagent consumption forecasts.

Testwork across geological domains, ore types, and weathering profiles to quantify metallurgical variability and define geometallurgical domains for mine planning.

Flowsheet development for sulfide-hosted, carbonaceous, telluride, and double-refractory gold ores using pressure oxidation, bio-oxidation, roasting, and ultra-fine grinding.

Integrated flowsheets for complex Cu-Pb-Zn, Cu-Mo, Cu-Au, and polymetallic sulfide ores with sequential or bulk flotation, selective leaching, and impurity rejection.

Process development for rare earth elements (REE), lithium (pegmatite and brine), graphite, vanadium, cobalt, manganese, and battery-grade material production.

Flowsheets for carbonates, clays, feldspar, garnet, mica, phosphate, potash, silica, wollastonite, zeolite, and specialty industrial minerals including brightness upgrading and impurity removal.

Custom process designs for improved recovery, throughput, and cost reduction.

We develop process flowsheets that are engineered to be built. Our metallurgists and process engineers work from bench-scale data through pilot programs to deliver flowsheets that meet bankable feasibility standards — with the confidence that comes from an organization that also builds the plants.

Deliverables

  • Process flowsheet diagrams with mass and water balances
  • Equipment lists and preliminary sizing
  • Reagent consumption estimates and operating cost inputs
  • Testwork reports suitable for NI 43-101, JORC, S-K 1300, and bankable feasibility studies
  • Recommendations for pilot-scale confirmation and engineering studies
