Expertise
Our engineers are process specialists first. That means the flowsheet drives the plant layout, not the other way round.
The commodities we know best.
Lead & Zinc
Roast–leach–electrowin, lead smelting and refining, Waelz, secondary zinc and residues.
Copper
Concentrators, smelting and converting, SX-EW, anode and cathode refining.
Gold & Silver
CIL and CIP, pressure and bio-oxidation, elution, electrowinning and refining.
Other Non-Ferrous Metals
Nickel, cobalt, antimony and complex polymetallic feeds.
Every unit operation from ore to refined metal.
Mineral Processing
Comminution, classification, flotation, separation and dewatering.
Pyrometallurgy
Smelting, converting, slag chemistry and refractory design.
