SPEAKER BIOS

  • Dr. Valeriy Kosynkin
  • Dr. Valery Kosynkin is one of the world's preeminent chemists and metallurgists for Rare Earth Elements

(REE). Dr. Kosynkin holds a doctorate of philosophy from Moscow State University. Since 1959, Dr. Kosynkin has been employed by VNIIHT – The Russian Leading Institute of Chemical technology, initially as a Researcher in Uranium technologies, and from 1973 as the Head of Research and Development for REE chemistry and

  • technology. Dr. Kosynkin has overseen the technical research and commissioning of REE production and

extraction facilities in Russia, Ukraine, Estonia and Kazakhstan.

Jean-Paul Tognet

  • Jean-Paul Tognet is a retired French chemist and nuclear engineer having spent his 35 year business career in

the Rare Earths sector. . In 1982, he began to lead the chemical engineering department at the Rhone-Poulenc Rare Earths plant in La Rochelle, France. Then, as Industrial and Raw Materials Director from 1992 to 1999 he managed the development of Rhone Poulenc RE plants in France, USA, Japan and China. Rhone Poulenc’s name eventually changed to Rhodia (now a branch of Solvay) where he continued global upstream management and finally was placed in charge of the evaluation of new Rare Earth projects globally

Steve Mackowski

  • Mr. Mackowski joined Hastings after serving at rare earths company Arafura Resources Ltd. as General

Manager Projects Development & Technology. Mr. Mackowski is a qualified engineer in mineral processing with

  • ver 30 years technical and operational experience in rare earths, uranium, industrial minerals, nickel, kaolin

and iron ore.
