AMI, Department Science and Technology in association with the SAIMM are hosting the
ZrTa2011
New Metals Development Network Conference
12 - 14 October 2011
Mount Grace Country House & Spa, Magaliesburg
The Advanced Metals Initiative (AMI) of the South African Department of Science and Technology (DST) facilitates research, development and innovation across the whole value chain in the field of advanced metals.
The goal is to achieve sustainable local mineral beneficiation and to increase the downstream value addition of local advanced metals in a sustainable manner through industry, relevant research and development, technology transfer, and ultimately, commercialisation.
ZrTa2011 aims to bring together researchers, industry and government stakeholders to share and debate the latest trends, research and innovative solutions in the field of zirconium, hafnium, niobium and tantalum metals. This is the focus of the New Metals Development Network of the AMI.
The event kicks off with a Student Seminar covering the full scope of the AMI on 12 October 2011. This includes all the networks, namely Light Metals (Ti, Al, Mg), Precious Metals (Au & PGMs), New Metals (Zr, Hf, Nb & Ta) and Ferrous & Base Metals. Students are encouraged to take advantage of this opportunity to share their research with peers and to improve their presentation skills.
Conference delegates will be treated to a cocktail reception function on the evening of 12 October 2011 and the conference dinner will take place the next evening.
ZrTa2011 formally starts on the morning of 13 October 2011 and runs through to the afternoon of 14 October 2011.
