SIDBEC-NORMINES was incorporated in 1976. In addition to the production of concentrate at Lac Jeannine, near Gagnon, from ore extracted from the Fire Lake mine, its operations now include, since the end of 1977, a secondary concentrator and a pelletizing plant at Port-Cartier.The main objective of SIDBEC-NORMINES is to produce annually six million tons of iron oxide pellets, of which three million tons with a low silica content are to meet the requirements of direct reduction.SIDBEC-NORMINES' pellet plant is located adjacent to the port facilities of Quebec Cartier Mining Company, east of Port-Cartier. The plant is designed to produce both types of pellets on two separate parallel agglomerating lines. The upgraded concentrate (plus 68% Fe) is produced utilizing wet high-intensity magnetic separators (Jones).In addition to the upgrading installations, the pellet plant includes a grinding section and a disc balling section; the induration of both types of pellets is carried out on two Dravo pellet furnaces, each of which has an annual nominal capacity of three million tons.This paper describes the process and the physical installations and reports on the results obtained since the start-up of the plant on November 29, 1977.
