About Durba


I support mining, metals, and battery-materials projects with process engineering and metallurgical expertise during conceptual, feasibility, and basic engineering phases.

My experience covers lithium, Au-Cu, REE, and precious-metals processing, with a strong focus on mass and water balances, process simulations (HSC, Aspen, Excel), flowsheet development, and equipment selection. I work closely with multidisciplinary teams, contributing to HAZOPs, CAPEX-OPEX evaluations, and clear, decision-oriented technical documentation.

I bring a practical, cost-aware engineering approach, helping clients de-risk projects and move efficiently from concept to execution.

Typical deliverables:
process flowsheets, mass & water balances, simulation studies, equipment selection concepts, and feasibility-level technical reports.
