Background and activities

Process metallurgist with extensive non-ferrous and light metal experience (Cu, Ni, Zn, Mg, and Al) and knowledgeable in electric furnace design.

Experienced in first-of-a-kind metallurgical plants and commercialization of new technology, including technology and financial risk management.  More than 20 years of experience in the metallurgical industry (nickel, ferro-nickel, zinc, copper, magnesium, aluminium and materials) in plant operations, project engineering and applied research.

Areas of Experience:

  • Process engineering – Flowsheets and modelling (Metsim®), mass-energy balances, P&ID’s, instrumentation selection, process control functional descriptions, HAZOP, standard operating procedures, materials of construction, continuous improvement
  • Finite element modelling (COMSOL® 4.2a) of liquid and induction systems including computational fluid dynamics, AC/DC, magneto-hydrodynamics and heat transfer
  • Induction heating – Coil design, work piece power, resistance, inductance, and impedance
  • Slag resistance furnace design – Prediction of resistance, electrode sizing, required transformer current-voltage range, estimation of thermal efficiency, cooled copper block design, high intensity operation, refractory and cooling systems
  • Smelting technology – Nickel Smelting Technology, Rotary Kiln Electric Furnace FeNi, Carbothermic aluminium, Spent aluminium pot lining, Mitsubishi process, Noranda reactor
  • Fluid particle technology – Flash drying, calcining, roasters, fluid beds, cyclones, classifiers
  • Pneumatic conveying and materials handling – Dense and dilute phase, screening, conveyors, airslides, bucket elevators, solids metering devices, storage bins and silos, etc.
  • Industrial gas cleaning – Electrostatic precipitators, baghouses, cyclones, acid plants
  • Magnesium production – Magnola Process, preparation of anhydrous magnesium chloride
  • Hydrometallurgy – Mixing and leaching, autoclaves, membrane technology
