Cabot Specialty Fluids, a division of Cabot Corporation, mines the TANCO pegmatite, near Lac du Bonnet, Manitoba. This paper describes TANCO's history and operations, including production changes brought on by market conditions. Also discussed are how changes in both technology and product specifications influence the mining and processing of the ore. TANCO began as an underground tantalum mining operation in 1969, with occasional shipments of pollucite (cesium ore) and rubidium ore. With the decline of the tantalum market in the early 1980s, TANCO shifted production to its large reserves of spodumene, a lithium-bearing mineral. Various grades of ceramic-quality lithium concentrate are produced, including 7.25% lithium, 6.8% lithium, -200 mesh and spodulite. Tantalum production recommenced in the late 1980s, and Cabot Corporation now exclusively purchases the tantalum concentrate. Pollucite became a primary ore in the mid-1990s with the creation of Cabot Specialty Fluids and its on site production of cesium formate, a high-density brine designed as a drilling fluid for deep-sea oil and gas wells. A recent expansion allows for the production of conventional cesium chemicals as well.
