ore, the estimated production for 1986 was reported as only 25 million st (2). This slump was partly due to the availability of cheaper and superior iron ore pellets from foreign sources and to the decline in domestic steel consumption. The decreased demand had a dramatic influence on the iron ore industry, as shown by the
