Feldspar mining in Canada came to an end during 1972 after many years of continuous activity. The deposits are not exhausted and the domestic demand for this product is expected to continue at about the same level as in recent years. The size of the industry does not justify the installation of expensive equipment in the mills, but it is believed that a modest profit could be made by a small operation using rudimentary methods of separation. Largescale and accurate mapping of the pegmatite dykes could help in planning mining operations for a better recovery of a uniform product.
