About Ahmad G.

Hi there!  My name is Ahmad Ghahreman (well, some people know me with my former last name which was a bit too long: Ghahremaninezhad!).  I joined the Robert M. Buchan Mining Department at Queen’s University in January 2014 with the intention to build a strong Hydrometallurgy Research Group at Queen’s University.

During the past years I have been fortunate to gain post-doctoral work experience with Barrick Gold Corp. as a Metallurgist at Barrick Technology Centre. Since joining Queen’s University I have been actively involved in many projects with the Government of Canada, several senior and junior Canadian mining companies, as well as international and US based mining companies, as a consultant.

My main metals of interest are gold, copper, strategic metals such as lithium and rare earth metals, minerals such as potash and nitrates, and I have been involved in several waste and toxic elements remediation projects, such as mercury problem in gold industry and arsenic immobilization process development.
