Ademir Ramirez

Process Manager, South America

Ademir is a chemical engineer with over 38 years of experience in the design, evaluation, construction and management of mining and chemical projects, specializing in extractive metallurgy for metalliferous ores, lithium brines and mineral salts.

I agree with Einstein – “Insanity is doing the same thing over and over again and expecting different results!” I am driven to always look for new ways.

Ademir is a highly skilled chemical engineer and mining industry expert with a broad range of experience in studies, project delivery and project/business management. As Process Manager at Ausenco, he is responsible for developing and overseeing a team of engineers focused on delivering projects/studies for copper, gold, iron, molybdenum and lithium. He is also responsible for further developing our lithium capabilities and for the strategic pursuit of lithium opportunities in Chile and Argentina.

Ademir has worked on numerous lithium projects in South America in various roles including project manager, study manager and senior process specialist. His major lithium project experience includes the La Negra Expansion Phase 3-4 (previously named Capricornio) where he was Process Lead, responsible for the application of a leading edge process for using salar brines and solar evaporation ponds. Additionally, he was a study manager for the Maricunga Lithium Project in Chile, responsible for the design of a lithium carbonate process plant. At SKM, he held the role of Chief Technical Officer and was a senior peer reviewer and project manager for various projects, including the role of functional peer reviewer for the feasibility study and basic engineering phases of the Olaroz Lithium Project in Argentina.

In the field of biometallurgy, Ademir was one of the pioneers in the development of a bioleaching process that involves a strain of archaea (a primitive species of bacteria) to leach sulphur minerals. He is a fellow member of the Instituto de Ingenioros de Minas de Chile and regularly presents papers at local mining and chemical conventions throughout Latin America.
