Advisory services
Focused technical input where operating and investment decisions meet.
Engagements are shaped around a defined plant problem, decision or review mandate.
Technical due diligence
Senior metallurgical review for feasibility, asset assessment, restructuring and capital decisions.
Service detailFurnace and refractory review
Review of loading, lining philosophy, freeze lining, electrode practice, tapping and equipment life.
Service detailRaw materials and process evaluation
Ore, reductant and process-route evaluation linked to plant constraints, product requirements and economics.
Service detailSelected operating outcomes
Results from furnace, sinter and copper-smelter assignments.
