Refractories recycling has 'limited impact' on primary mineral de

摘要

The recycling of used refractory products to provide a source of raw materials has only slightly dented demand for virgin minerals, recent analysis of the refractories market shows. Minerals targeted for reclamation in the recycling process include magnesia, alumina, zirconia and silicon carbide, although the economic viability of using secondary sources of these materials has been strained by low prices in primary markets.
