Process Development

Romke Kuyvenhoven starts MDE Minerals Consulting in 2021, with a primary focus on consulting services for robust NI43-101 based geometallurgy and development of sustainable metallurgical processes, contributing to the success of exploration projects and the operational improvement at existing mineral processing plants.

About MDE Minerals Consulting

Romke Kuyvenhoven

Romke Kuyvenhoven, Senior Consultant, M.Sc., MBA

Romke Kuyvenhoven has 25+ years of experience in geometallurgy and process development for applied research projects and for engineering studies at scoping, PEA and PFS level. Her focus has been primarily on porphyry copper and IOCG deposits, with a more recent focus on cobalt as well. She is permanently based in Chile and fully bilingual English-Spanish. More than two decades of professional activity in the region has given her a profound understanding of the Chilean culture and business climate, including extensive experience with NI43-101 reporting regulations.

Sustainable mining development

Sustainable Mining Development in the Andean Region

Adequate management of Environmental, Sustainability and Governance (ESG) aspects is of critical importance. The identification of best processing routes and inclusion of innovative processing technology is a challenging and necessary task, to assure the successful development of a greenfield project. Compliance with local environmental regulations, accomplishment of the financial expectations of the owner's team, and a constructive and long term relationship with neighbouring communities and other stakeholders, are all key in the definition of that succes.
