Industrial Minerals also reports that it has some good news to share at last! It would appear that prospects are promising for the sillimanite group minerals (andalusite, kyanite, sillimanite, and mullite), whose key market is refractories, followed by casting, abrasives and ceramics. At the expense of bauxite, and with the refractories market showing some signs of initial recovery, those active in the supply of sillimanite minerals might be forgiven for some cautious optimism not long after the dark days of 2009. Imerys has recently unveiled its Euros 30M investment in new and expanded aluminosilciate refractory raw materials supply, and the much awaited Peuvian andalusite source is beginning to show serious signs of coming to fruition.
