STOICISM presented in the 28th International Mineral Processing Congress (IMPC) in Québec, Canada


    As partner of the STOICISM consortium, Dr. Quentin Dehaine from University of Lorraine, presented orally “Rare earth and rare metals recovery from the micaceous residue using combined gravity/flotation processing route” at the 28th International Mineral Processing Congress (IMPC) that took place from 11 to 15 of September in Québec (Canada). His contribution presents the results of statistical analysis, combined with qualitative mineralogy and highlights the main mineralogical associations and identifies monazite, cassiterite, Nb-rutile and wolframite as the main heavy minerals from the kaolin deposits of St. Austell (UK). In addition, the low grade and fine size range make difficult their recovery by gravity concentration only. In terms of distribution, the metals are predominantly in the finest fraction with 95% of the LREE, 84% of the Sn, 87% of the Nb and 83% of the W distributed in the fine fraction below 100 µm.

    The IMPC, since 1952 and with its over 60 years of existence has been a major driving force for the promotion of excellence in scientific and technical knowledge in mineral processing and extractive metallurgy worldwide. The congress over the years has become truly international with delegates from all parts of the world deliberating on issues facing the mining and minerals processing industry globally.

    With around 1200 participants from 60 countries, 600 oral presentations, 80 industry exhibitors this 28th edition provided the opportunity for networking with peers and partner’s between technology providers, leading universities, as well as improved exchange between process engineers, industry, academia with aim to promote the new techniques of concentration and separation of different ore bodies.
